Drywall mud, also called joint compound, is a gypsum-based paste used to finish drywall joints and corners in new drywall installations. It’s also handy for repairing cracks and holes in existing drywall and plaster surfaces. Drywall mud comes in a few basic types, and each has its advantages and disadvantages. You may choose one type for your project or use a combination of compounds for the desired results.

What Is Joint Compound or Mud?

Joint compound, commonly called mud, is the wet material that is used for drywall installation to adhere paper joint tape, fill joints, and to top paper and mesh joint tapes, as well as for plastic and metal corner beads. It can also be used to repair holes and cracks in drywall and plaster.

Types of Joint Compound

All-Purpose Compound: Best All-Around Drywall Mud

Professional drywall installers sometimes use different types of muds for different stages of the process. For example, some professionals use a mud just for embedding paper tape, another mud for setting a base layer to cover the tape, and another mud for topping the joints.

All-purpose compound is a pre-mixed mud sold in buckets and boxes. It can be used for all phases of drywall finishing: embedding joint tape and filler and finish coats, as well as for texturing and skim-coating. Because it is lightweight and has a slow drying time, it’s very easy to work with and is the preferred option for DIYers for coating the first three layers over drywall joints. However, an all-purpose compound is not as strong as other types, such as topping compound.

A specialty form of all-purpose compound is known as lightweight all-purpose mud, which is similar to standard all-purpose mud but is lighter in weight. Some pros find it inferior for taping seams since it contains less binding agent. The lightweight form of all-purpose mud is sometimes used for the first and second coat on seams and for finishing corner bead. It is a very easy mud to sand.

Topping Compound: Best Mud for Final Coats

Topping compound is the ideal mud to use after the first two coats of taping compound have been applied to a taped drywall joint. Topping compound is a low-shrinking compound that goes on smoothly and offers a very strong bond. It is also highly workable. Topping compound typically is sold in dry powder that you mix with water. This does make it less convenient than premixed compound, but it allows you to mix just as much as you need; you can save the rest of the dry powder for future use. Topping compound is sold in pre-mixed boxes or buckets, too, though, so you can purchase whichever type you prefer.

Topping compound is not recommended for embedding joint tape—the first coat on most drywall joints. When applied properly, a topping compound should reduce your sanding time in comparison to lightweight compounds, such as all-purpose mud.

Taping Compound: Best for Applying Tape and Covering Plaster Cracks

True to its name, a taping compound is ideal for embedding joint tape for the first phase of finishing drywall joints. Taping compound dries harder and is more difficult to sand than all-purpose and topping compounds. Taping compound is also the best option if you need to cover plaster cracks and when superior bonding and crack-resistance are required, such as around door and window openings (which tend to crack due to house settling). It is also the best mud option for laminating drywall panels in multi-layer partitions and ceilings.

Quick-Setting Compound: Best When Time Is Critical

Commonly called “hot mud,” quick-setting compound is ideal when you need to finish a job quickly or when you want to apply multiple coats on the same day. Sometimes called simply “setting compound,” this form is also useful for filling deep cracks and holes in drywall and plaster, where drying time can become an issue. If you are working in an area with high humidity, you might want to use this compound to ensure a proper drywall finish. It sets by chemical reaction, rather than simple evaporation of water, as is the case with other compounds. This means that quick-setting compound will set in damp conditions.

Quick-setting mud comes in a dry powder that must be mixed with water and applied immediately. Be sure to follow the manufacturer’s recommendations prior to use. It is available with different setting times, ranging from five minutes to 90 minutes. “Lightweight” formulas are relatively easy to sand.

What Are Dry and Pre-Mixed Joint Compounds?

Drywall joint compound comes in either of two forms: dry or wet. Dry joint compound is the classic type that has been used for years and is still used by professionals. Wet joint compound is a newer product more aimed at the residential do-it-yourselfer.

Both dry and pre-mixed joint compounds contain latex additives to add strength and flexibility. When mixed appropriately, both cover the same amount of drywall: about 125 to 150 pounds of compound covering about 1,000 square feet of drywall panels.

Dry Joint Compound

Joint compound in the dry form is a powder that usually comes in large paper bags. The dry product must be mixed with potable water in a separate container to form workable mud. This product is usually not labeled as being dry. Simply, it will be called joint compound with the qualifiers ready-mixed or pre-mixed omitted.

Pre-Mixed (Wet) Joint Compound

Wet joint compound, called pre-mixed or ready-mixed, is available in plastic buckets. All water necessary has already been added to the joint compound, though it is possible to thin out the consistency with additional water.

Should You Buy an Electric Joint Compound Mixer?

If you do decide to go the dry joint compound route, an electric mixer may help with mixing since the product is heavy and stiff.

It is possible to mix small amounts of dry mud with an electric corded drill and a paddle mixer. But a mud mixer has a strong motor and low torque for turning heavy compounds, even small mixes of concrete. Plus, it saves your drill for what it was made for: drilling.

How much mudding with dry mix would you have to do to justify the purchase of a mud mixer? Since dry joint compound costs virtually the same amount per square foot of coverage as pre-mixed joint compound, purchasing an electric mixer may only make sense financially if you will need to use it often and with huge quantities of dry joint compound: A good 1/2-inch electric drill with a 7 or 8 amp rating will mix a small quantity of mud easily.

Tip

For most applications, dry and pre-mixed joint compound are virtually the same, although the pre-mixed option requires less prep work. Common reasons to choose dry mix are that it can dry more quickly, is easier to mix and use in very small amounts, offers extra adhesion when using mesh tape, and has an extra-hard set.

Note that skim coating is extremely thin and is considered to be part of a premium level 5 drywall finish, something that few homeowners will ever take on. Since most drywall finishing confines itself to narrow joint strips, you would need to finish around 400 average-sized rooms’ joints to justify the cost of the machine.

Hot Mud Drywall Process: Your Complete Guide

If you’re new to the home improvement scene, you may be shocked by how many different types of drywall and drywall supplies there are. And the first time you hear the term “hot mud,” you might picture brown, goopy soil at high temperatures. If you’re not sure how to use hot mud, or what it is, keep reading for the complete guide to the hot mud drywall process.

What is mudding?

Mudding involves layering thin coats of a special compound over the drywall joints, scraping it smooth, and ensuring that all cracks and crevices are covered so you have a nice, flat surface to paint later. You may have to apply several coats of drywall mud, depending on the condition of the wall.

The compound you’ll use, far from being brown like regular mud, is typically white, textured like paste. Once you apply it, it needs time to dry and cure, and then it will need to be sanded smooth before you can proceed to the next step.

What is hot mud for drywall?

“Hot mud” is simply a term used to refer to the drywall compound that you mix up yourself. The word “hot” indicates that once you mix up a batch, you’d better get started and use it quickly because it will begin to set within the amount of time listed on the bag.

Hot mud drywall mix comes in powder form, usually packaged in paper bags with a tough plastic lining to keep moisture out.

Why choose hot mud drywall products?

You can buy pre-mixed drywall compound, but some contractors and homeowners prefer to mix the compound themselves so they can obtain the consistency they want. Plus, hot mud tends to be cheaper, since the burden of the labor rests on the purchaser.

Hot mud drywall products tend to act like cement once they’re mixed in that they have a limited lifespan before they harden beyond usability. However, the hot mud drywall compound gives you a tough bond and sturdy result.

In addition, these compounds often dry faster than the pre-mixed versions. If you’d rather not wait around for hours to start the next step in your project, a hot mud drywall compound might be the right choice for you.

Hot mud deadlines

When you purchase the bags of powder for mixing up your hot mud, be sure to choose a variety that suits your timeline. For example, some types of hot mud set very quickly. Silver Set 20 by Beadex can be worked for only 20 minutes before it begins to set.

You’ll find bags labeled with other time limits, like 40 minutes or 90 minutes. Consider the size of your project and select a type of hot mud with a workable time span.

When to start mudding?

When you’re preparing a wall for finishing, you first place the sheets or panels of drywall and screw them to the studs. Make sure all your screws are drilled in tight, and then pack that drywall compound firmly into the crevices and scrape it smooth. Next, tape those sections with paper drywall tape, self-stick fiberglass tape, or a similar option.

Once the room is taped, you can use more drywall mud along the joints of the drywall sections. The seams at the edges of the rooms are particularly important and difficult to do, so take your time on the corners and along the lines where the walls meet the floor or ceiling. You can purchase inside corner tools to make these areas easier to treat.

How to use hot mud?

Be sure you have all your tools on hand: paddles, knives, buckets, trays, hot mud drywall mix, a face mask or filter, and a power mixer to stir the compound. As with any chemical substance, follow the instructions on the package precisely and adhere to any rules of safe usage. You should begin by filling your mixture bucket with water; if you put the powder in first, the texture of your hot mud won’t be right.

If your compound looks too soupy, add more powder. If it’s too thick, add a bit of water. It may take a few tries to get a perfect consistency, which is a thick yet workable paste, almost like cake frosting. Always mix a little more compound than you expect to need, so you don’t have to stop in the middle of the job to mix up more.

Keep in mind that hot mud doesn’t always provide the smoothest finish. If the consistency isn’t just right, you may end up with a bumpy or grainy surface. You can sand the imperfections or use a final layer of pre-mixed, all-purpose mud to finish things off.

If you’re nervous about using hot mud drywall compound the first time, choose a single wall or a small section of the room, rather than attempting an entire room in one sitting. Once you’ve played around with the compound, you’ll feel more comfortable hot mudding the other areas of your space that need attention.

Different Types of Drywall Mud

Last time you visited the local hardware store or big box home improvement store like the Home Depot® or Lowes® looking for drywall mud you may have been puzzled by the variety. Do all joint compounds work the same or should you use a certain type of mud for certain applications?

Let’s discuss the two basic categories of drywall mud. Then we can discuss the choices within each category. This article is not meant as a review of any brand or recommendation of a certain product line, rather this is a general discussion that applies to several different brands of drywall compound.

What are the two main categories of drywall mud?

Quick-Setting Drywall Mud – “hot mud”

Pre-Mixed Drywall Mud

Quick-setting or “hot mud”.

Quick-setting drywall mud comes in powdered form usually in plastic lined paper bags. The plastic lining keeps moisture out and preserves freshness. Keeping the powdered mud dry is critical. When water comes in contact with hot mud it begins an irreversible chemical reaction that causes the mud to harden.

Once quick-setting drywall mud hardens you cannot reuse it. If a bag of hot mud contains even a few small pieces of hardened mud, it can render the entire bag unusable. Hardened lumps of hot mud cause scratches in drywall seams and make it very difficult to create truly smooth finishes.

Hot mud set time

When it comes to hot-mud, there is a difference between hardening and drying. Hot mud hardens as a result of a chemical reaction. Manufacturers mix different amounts of hardening agents into the material causing it to set up at different times.

Hot mud is packaged according to the time it takes to harden. For example, quick-setting drywall mud is sold in packages labeled 5-minute, 20-minute, 45-minute, 90-minute or higher. This refers to the length of time it takes from when the powder comes in contact with water to when it hardens and can be re-coated.

Actual working time is generally less than the time listed. For example, 45-minute hot mud may begin to set up in 30-35 minutes. Hot dry conditions can cause 5-minute mud to set before you even get a chance to spread it on your patch.

The working time can vary slightly depending on a few factors. High humidity or cooler temperatures causes hot mud to take longer to set. If you need quick-setting drywall powder to set up faster than normal, mixing it with hot water instead of cold will usually do the trick.

Hot mud dry time

Remember, the time associated with quick-setting drywall compound is the hardening time, not the drying time. For instance, even though 45-minute hot mud may harden within 45 minutes, it can take several hours to dry completely depending on ambient temperature and humidity levels.

When using hot mud you will notice it turn from dark grey to white. The mud is not considered completely dry until it turns completely white in appearance. Unlike traditional drywall compound, it does not shrink as it dries, so it is possible to add additional coats of hot mud before it has completely dried. It is best however, not to paint over hot mud until it has completely dried.

When to use “hot” mud

Quick-setting drywall mud is great for small patch jobs where you don’t want to wait 24 hours before applying a second coat. Hot mud is also used on large drywall jobs for bedding-in mesh drywall tape. This allows the pros to tape and first coat seams all within the first day on a job.

Many pros feel that quick-setting mud provides a stronger base coat and therefore protects better against cracking. Because of this, some use it as a first coat when finishing corner bead.

Most pros agree that when you use mesh drywall tape, you should always use quick-setting mud as a first coat. Mesh tape does not provide a strong a bond with the drywall paper and therefore needs the added strength of hot mud. Some manufacturers recommend using quick-setting compound when choosing mesh tape.

Quick setting mud is rarely used as a finish coat. Quick setting mud is more difficult to sand than “lightweight all purpose” mud which makes it very difficult to create truly smooth surfaces. Even when hot mud is used for coating patches, a skim coat of lightweight all purpose mud is often used to finish the patch.

There are several brands of quick-setting drywall mud. The pros all have their preferred brands and different reasons for each. Two popular brands are USG SHEETROCK_® brand EZ-sand and Gold Bond_® brand Pro Form_® quick-setting drywall mud.

Why is it called “hot” mud?

Why is it called “hot” mud? We cannot say for certain how it got that name but there are a couple of possibilities. As hot mud hardens, the chemical reaction creates a small amount of heat which may be a reason some people call it hot mud. Or, it could simply come from the fact that you have to move quickly because it will harden up on you if you don’t finish within its specified time.

What is Durabond

_®?

Sometimes you will hear hot mud referred to as Durabond_®. Durabond_® is a trademarked name that refers specifically to a product made by USG_®. It was one of the first types of quick setting drywall mud that was used extensively in the workplace and for this reason the name became closely associated with quick setting drywall mud.

Durabond_® is similar to Sheetrock_® in that it is simply a brand name that has become popular over the years. Most tradesmen these days prefer types of quick setting drywall mud that are easier to work with and easier to sand than Durabond_®. But in some areas, all brands of hot mud are referred to as Durabond_®.

Pre-mixed drywall mud

The other main category of drywall mud is pre-mixed drywall mud. This is what most people think of when they talking about drywall mud.

Pre-mixed drywall mud is sold in either 4.5 gallon buckets or in boxes (cartons) containing a plastic bag of mud. Most often, the boxes of mud are also 4.5 gallons in volume but occasionally you will find 3.5 gallon boxes. Therefore, if you see a box of drywall mud that seems cheeper than most, make sure to check the volume. Pre-mixed drywall mud is, as the name indicates, pre-mixed and ready to use.

Pre-mixed drywall mud is almost always thinned with water before using. The amount of water used depends on how the mud will be applied. For example, bedding in tape requires a thinner than normal consistency.

A thin consistency is also needed when using automatic taping tools to allow a smooth flow of mud through the drywall mud pump. However, if it is too thin, it will be difficult to spread and will shrink back, creating voids. Texture mud is the thinnest of all. It takes time and training to understand what consistency of mud should be used with each application.

When shopping for drywall mud you may notice different types of pre-mixed mud. The three most commonly used are “all purpose”, “lightweight all purpose” and “topping”. There are of course several other types of joint compound available however these are the most common.

All Purpose Joint Compound

All purpose drywall mud, as the name indicates, is made for all applications. All purpose mud has bonding agents that increase the holding power of drywall tape so it is good for bedding in seams. It is sometimes used to first coat seams and corner beads.

All purpose is not often used as a finish coat because it is more difficult to sand than “lightweight all purpose” joint compounds. However some professionals will use it in limited applications for finish coat because it creates a durable finish. The downside is that it is harder to sand and therefore, the finishing has to be of very good quality.

Lightweight All Purpose Joint Compound

Lightweight all purpose drywall mud, as the name indicates, is made for all applications yet is lighter in weight than all purpose mud. Many pros believe that lightweight joint compound contains less binding agents and therefore is inferior when taping seams. However, it is hard to know for sure since manufacturers don’t openly publish comprehensive lists of drywall mud ingredients. Lightweight compound is often used for first and second coat of seams and corner bead. It is almost always used as a finish coat because of its ease of sanding.

Topping compound

Topping compound is used less often then all purpose or lightweight mud. It can be used to top coat seams and corner bead. It is not recommended for taping joints. Topping compound is whiter in color than all purpose and even whiter than lightweight all purpose. One common use for topping mud is texture applications.

Are joint compounds compatible with one another?

Generally speaking, all types of drywall mud are compatible with one another. Joint compounds can be used over each other but most manufacturers do not recommend mixing the compounds together. It is always the best practice to refer to the manufacturer’s specific recommendations.

Drywall mud comes in both premixed and powdered varieties. DIY-ers usually prefer premixed drywall mud because it’s ready to use out of the bucket and requires no preparation.

Professional drywall finishers tend to prefer mixing their compound, allowing them to get the mud to their preferred consistency.

Whether using dry or premixed mud, there are several different types of mud, each designed for various purposes. Depending on what stage in the process you’re at, you’ll find that one kind of mud is best suited for that portion of the project. These include:

Quick-setting joint compound (hot mud)
Taping mud
Topping mud
All-purpose joint compound
Lightweight all-purpose joint compound

5 Types of Drywall Mud, Explained

Now that we have a rough idea of the different types of drywall mud, let’s examine them in greater detail so you can choose the best product for the job.

1. Quick-Setting Joint Compound

Our Top Pick

Quick-setting joint compound, which is commonly referred to as hot mud, is a powdered product you mix with water to create the compound.

What separates this compound from other types of drywall mud is how quickly it hardens, and hardening agents are added to the powder so it sets up more rapidly than other compounds. Quickset is available in a variety of setting times, ranging from 20-minute to 90-minute.

The faster the drying time, the less time you have to work with the mud before it hardens. As time elapses, the product becomes more challenging to work with.

As soon as quickset is mixed with water, the working time clock starts, so you’ll want to keep that in mind when selecting a compound. Exposure to air and moisture can begin the chemical reaction that causes quickset to harden.

So you must keep the unused product airtight and in a dry location. Quickset is often used for embedding tape in drywall because it helps encourage adhesion between the tape and drywall paper, and it provides a stronger bond than all-purpose products.

But, it doesn’t sand well, so it should never be used as a finish coat since it’s challenging to achieve a smooth and consistent finish. Quickset is an ideal product for instances where time is an issue.

For small patches, quickset can allow you to finish the job in a day, instead of having to wait 24-hours to sand and paint the patch. It’s also useful for embedding tape and for taping and applying the first coat on the seams in one day.

2. Taping Mud

Out Top Pick

Taping compound is very similar to quickset because it contains bonding agents that help with adhesion during the taping process. But, taping mud dries more slowly than quickset, and it’s more forgiving to work with, especially for beginners.

This product dries hard and resists cracking, making it an excellent choice for fixing plaster cracks and making repairs. Taping mud is also a smart choice for areas around doors and windows that are more prone to cracking as the building settles.

Like quickset, taping mud is difficult to sand, so it’s never used for topcoats because it’s so challenging to finish well.

3. Topping Compound

Topping compound is typically used for the final polish coats on a new drywall installation or texturing a wall. Of all the drywall compounds, topping compound generally is the easiest to work with, and it provides the longest working time.

Once it’s dry, topping compound is extremely easy to sand, and it cuts down finishing time compared to other drywall compounds, including lightweight all-purpose.

Reach for this compound after you’ve already applied two coats to your taped joints, and it will help you save time on sanding and finishing.

4. All-Purpose Joint Compound

Our Top Pick

USG 380501-048 380501 Mix Joint Compound

Check Latest Price

We may earn a commission when you click this link, at no extra cost to you.

All-purpose compound is the one-stop-shop of the joint compound world, and you can use it confidently for every phase of drywall finishing. All-purpose compound is reasonably lightweight, provides a long working time, and it’s easy to use.

All-purpose compound contains enough binding agents that it can be used for taping seams.

But it’s still easy to sand, which makes it a fine choice for polish coats, as well. All-purpose joint compound is typically sold in buckets, and it has a blue lid to differentiate it from other premixed compounds.

5. Lightweight All-Purpose Joint Compound

Our Top Pick

Usg Beadex Lite All Purpose Joint Compound

Check Latest Price

We may earn a commission when you click this link, at no extra cost to you.

Lightweight all-purpose compound is a lighter-weight product that’s exceptionally easy to use. It doesn’t contain as much binding agent as standard all-purpose, so most pros will avoid using it when taping joints. However, its lightweight consistency and ease of sanding make it an excellent choice for finish coats.

Since lightweight compound is so easy to apply, it’s a popular product to use when a heavier coat is necessary. Reach for lightweight compound when coating over corner bead, around electrical boxes, and other areas that require extensive coverage.

Premixed vs. Powdered Joint Compounds

Joint compounds come in both premixed and powder varieties. The premixed product is sold in large buckets, and it’s ready for use right out of the bucket.

Powdered joint compounds come in large paper bags, and they must be mixed with water to the proper consistency before they’re ready for use. Either product can be used for all your drywall finishing needs.

It’s mostly a matter of personal preference. Powdered compound is slightly less expensive, has a longer shelf life, and is protected against freezing.

Premixed compound is a bit more expensive, but it’s ready to use right out of the bucket. The trade-off with premixed compound is that it’s useless if it freezes and it’s susceptible to mold and spoilage.

Things to Consider

irote Chuenwiset/Shutterstock

Whether you’re a seasoned pro or a DIYer looking to tackle your first drywall project, there are some things to consider that will help you take your project to the next level. Here’s what you’ll want to keep in mind:

Ensure any nails or screws are properly driven just below the face of the drywall.
Use a utility knife to trim off any loose or torn paper from the drywall before you begin spackling.
Use a primer to prep any areas where there is torn paper before finishing them.
Use a quick-setting compound to fill gaps where two pieces of drywall meet before you begin taping.
Use a quick-setting compound for your first coat over areas that require extensive compound, such as over corner bead.
Cut out areas where tape has bubbled and coat with additional compound. Tape bubbles are impossible to hide and will show through on the final surface.
Thin out premixed compound with a bit of water so that it flows more smoothly and is easier to use.

Frequently Asked Questions

Below are some of the most common questions DIYers have about the different types of drywall mud.

What are the different types of drywall mud?

Drywall pros use various products at different stages of the finishing process. While it’s possible to achieve a solid finish using a single product, you’ll be able to achieve a premium wall finish if you use the proper mud at each stage of the job.

All-purpose joint compound: Solid all-around performance, and it can be used for all phases of taping.
Lightweight all-purpose joint compound: Light and easy to use. Not as durable as other compounds.
Taping mud: Contains additional binding agents to adhere to the tape—best for taping.
Topping mud: Harder with less shrinkage than other compounds. Ideal for finish coats.
Quick-setting joint compound: A quick-drying joint compound that allows you to save time, but is more challenging to work with.

What is the difference between spackle and drywall mud?

Drywall mud or joint compound is a wall finishing material made from gypsum and limestone. It’s used when taping walls during new construction or significant wall refinishing projects. Spackle is quite similar to joint compound.

But it also has binding agents to help it adhere to the wall surface. Spackle is typically best for small repairs, while drywall mud or joint compound are preferred for larger projects.

What type of mud should I use?

The type of mud you use depends mainly on the project you’re working on and the finish quality you’re looking to achieve. You could use an all-purpose compound for every phase of the taping process, but you can achieve the best results by using the correct compound for each job stage.

Taping compound is ideal for the first two tape coats, while a topping mud for the polish coats will reduce your sanding time and help you achieve a premium wall finish.

What is the easiest drywall mud to use?

Lightweight all-purpose joint compound is typically the easiest drywall mud to use. Most brands use a green lid to differentiate the lightweight from regular all-purpose compounds.

This mud provides excellent coverage, and it’s easy to sand. But, it isn’t as durable as other compounds, so professionals usually opt for regular all-purpose or specific compounds for each phase.

What is 20min mud?

When you see drywall mud sold as 20-minute, 45-minute, or 90-minute, this refers to the time it takes for the mud to set up. 20-minute mud is the fastest setting drywall mud.

It can be recoated 20 minutes after it’s mixed with water. Because of its shorter setting time, 20-minute mud is the most difficult product to use.

Does premixed drywall mud go bad?

Both premixed and powdered drywall muds have a shelf life. Usually, the manufacturer’s recommended shelf life is 9 months after opening for premixed compound and 1 year for powdered.

If kept properly in an airtight container, drywall mud can last far beyond its shelf life. Exposure to air dramatically reduces both products’ shelf life, which is especially true with premixed mud.

If the mud is discolored, has a foul smell, or isn’t as pliable as it should be, you should throw it out and use new drywall mud for your project.

So, What Are the Types of Drywall Mud?

Whether you’re making a minor repair or tackling a significant wall finishing project, using the correct type of drywall mud is the foolproof way to achieve a smooth and professional wall finish that will stand up to the test of time.

As you get more comfortable with drywall finishing, you’re sure to pick up some tricks along the way that allow you to work faster and cleaner while achieving an excellent finish.

As a beginner, use what you’re most comfortable with, and always look to learn new tricks and techniques to improve your finishing skills.

A one-hour drywall mud patch!

Not every drywall repair requires new sheetrock installation. In a lot of cases, a simple coat of drywall mud can hide gouges and unfinished areas. This article shows you how to make simple mud patch repairs to your walls. And carry out the whole process in one hour or less!

Tool List:

Spray bottle

Drywall sanding paddle

Mesh screens

Margin trowel

Best Picks:

A 13″ MUD PAN is perfect for mixing and containing small batches!

Likewise, a 12” TAPING KNIFE gives great, broad smoothing ability.

A HEAT GUN is the secret to FAST mud patches! WAGNER makes a great one:

Step 1: Choose Your Joint Compound

Bags of 20 minute drywall mud

Are you ready to tackle drywall repairs? Many homeowners buy 5 gallon buckets of joint compound. Admittedly, these bucket portions can be helpful for mudding an entire room. However, they are overkill for patching small areas.

Introducing Hot Mud

A far more effective solution is using 20-minute joint compound. This fast-setting powder is perfect for carrying out numerous small projects over time. (It can be found at Lowes or Home Depot.)

Typically, you just need a few cups for a small repair. Then, store the rest of the compound in a heavy garbage bag. Tie off at the top to prevent the powder from taking on moisture.

I realize you may be intimidated by the idea of mixing your own drywall mud. But, once you see how easy it is in the steps ahead, you might change your mind.

Step 2: Prep The Area

Sanding an unfinished area to prepare for a drywall patch

To begin your repair, lightly sand the area where you’ll apply your mud patch. (Here, a wall-mount sink was removed..)

When you sand the wall, you provide the area with more “tooth”. In other words, you roughen the existing texture. That makes the new mud grip the surface better.

Use your drywall sander paddle to pass a low-grit mesh pad over the area in sall circular sweeps. Be sure to scour a space several inches larger than the repair site itself. This helps when you “feather” the drywall mud outwards.

Step 3: Mix Your Joint Compound

Pour just a little bit of water into your mud pan. About a ¼” depth is good to start with. Now, use a cup to begin shaking the dry joint compound into the water in the pan.

Cover the water with joint compound (the powder will mostly float on the surface). Then, use your margin trowel to mix the components.

Drag the trowel edgewise through the center of the pan slowly. Sudden motions at this point will just cause a powder explosion! Very carefully swirl the two parts together until the water begins to soak the powder. When this happens, you have a lumpy paste in the pan.

Now, work the trowel through he mix more vigorously. Periodically scrape the walls of the pan. This pulls the paste towards the center, where it can be mixed effectively. It also keeps your pan clean.

What Result Am I Looking For?

Ultimately, the goal is to achieve a consistency similar to peanut butter. The mud should hold the shape of a groove when you drag your finger through it. Very importantly, eliminate any chunks or bubbles in the mixture. That keeps pockets of air or dry powder from showing up on the wall later.

If your mixture seems too soupy, add a little more compound. If it seems too doughy, splash in a little more water. A little experimentation will help you get the right combination.

Here’s a good video for mixing small batches:

Step 4: Let The Fresh Drywall Mud “Set Up”

When your drywall mud is the right consistency, set it aside for a full minute. A chemical reaction is taking place in the pan. The mud is achieving something known as a “false set.”

I have no idea why this occurs, but every good plasterer knows about it. The compound thickens somewhat at this point. But don’t worry. It’s just a natural part of the chemical process.

When a minute is up, mix the mud again. This quickly softens the mud in the pan. Work it right back into a smooth consistency. Now, you’re ready to apply!

Step 5: Trowel The Mud Onto The Wall

Trowel the first coat of mud onto the wall, using your 12″ drywall knife.

We’re not covering tape joints in this project. Therefore, there’s really no point to use anything but a 12” drywall knife. The wider blade will really help “fan out” the material. (If your patch area is really small, use a smaller knife, 4″ or 6″).

Press the blade of the knife into the compound and drag some to the side of the pan. Now, press firmly. Scrape the blade up the wall in a smooth draw. This pulls the mud on the edge of the knife from the mud in the pan. As well as you can, minimize ridges.

Keep It Clean!

If you have some compound on the back of the knife, scrape it off on the top edge of the pan. Also, make sure there aren’t any globs hanging off the sides of the knife. You want a clean “line” of mud sitting on the edge of the blade.

Spread the mud onto your repair area. Leave the thickest amount in the center of the repair area. Work your way outward to the edges.

Don’t worry about ridges in the patch at this point. You just want to get the whole area covered. Make a soft, low mound of mud, thin to non-existent at the edges; deepest in the middle. (By deep, I mean no more than 1/8” or so. )

Keep a bucket half-full of water nearby for cleaning off your tools. Scrape any excess mud into a trash bag, then clean out your mud pan thoroughly in the bucket. Let your pan and drywall knives dry to prevent rusting.

Your first coat is done! You’re ready for the interesting part…

Step 6: “Reactivate” And Scrape The Drywall Compound

I learned this trick from a master plasterer. It’s a bit difficult to get the hang of. But when you do, you speed up any plaster repair ten-fold!

Wait until the drywall mud becomes a bit stiff on the wall. It’s hard to say for sure when this will happen. Factors in your house like air temperature and moisture content cause the mud to dry faster or slower.

For twenty-minute joint compound, though, it’ll generally occur after about 15 minutes. The compound begins to take on a dull, greenish color. The mud no longer moves when poked or scraped.

Lightly spray your new patch.

Spritz!

When this happens, use a spray bottle to squirt a fine mist of clean water onto the mud. Be sure to soak all the mud. (You may want to tape a piece of plastic to the wall below—water dribbling down will get on your base trim otherwise.)

When you wet the mud at this stage, you briefly “reactivate” it. This makes it workable for a few more minutes.

With the area thoroughly wetted, pull your 12” knife over the area. Do this from the outer edges toward the center.

Work the mud again. Pull from the edges inward.

When you do this properly, the mud begins to smooth out. A slurry of mud paste builds up on the edge of your blade. Keep it there! It will fill in divots and pocks as the blade travels over the surface.

Don’t go overboard here. You just want to flatten out the highs and fill in the lows on the wall. It drastically cuts down on the need to sand later. It will also set you up for the next smooth coat!

Step 7: Dry The New Drywall Mud With A Heat Gun

Dry the new mud with a heat gun. Be careful! These things get HOT.

(WARNING: This next step speeds things up tremendously if you want to try it. BUT BE CAREFUL! A heat gun produces an incredible amount of heat. If you misuse it, you can even cause a fire.)

Painters and drywallers speed up the set time of their hot mud by using heat guns. This quickly dries wet paint and mud. I utterly rely on heat guns for small repairs like this.

Plug the gun in, switch it on, and position it a few inches away from your wall patch. Move the gun around in a pattern. Pass it back and forth repeatedly over the entire area.

The heat from the gun causes the patch to “parch,” or go through the drying process very quickly. You’ll see this happen as the compound goes from a smooth, dullish gray to a bone-white color.

Don’t let the gun point at any one area for too long! Move it around until the whole area is relatively dry.

Set the gun aside when the patch is fairly dry. BUT BE EXTREMELY CAREFUL! The nozzle is hot enough to burn anything it touches. Ff possible, hang the gun up by the little hook provided, or set it on a stone or concrete surface.

Step 8: Repeat The Process

A second coat of drywall mud has been applied to the patch.

At this point, begin the entire process again. Lightly sand the wall patch with a medium-grit mesh, just enough to give it a little more tooth. Then, mix up another batch of joint compound and trowel it over the first patch.

Pull this layer out just a little wider than the first. Remember to pull the mud from the perimeter towards the center. Focus on getting a smooth finish this time around. Work with smaller amounts of mud on your knife.

When the second coat begins to set up, repeat the spraying process. Then trowel mud towards the center of the patch once more, smoothing the mud.

Ideally, all traces of the old damage should be gone now. Your patch surface should look fairly smooth. Dry it with your heat gun. But clean your tools first!

Notice that dark spots emerge through newly dried areas after a few moments. This is moisture escaping from deeper regions of the patch. Pass the heat gun over these areas until no new dark spots emerge.

Step 9: Sand the Drywall Patch

Sanding the new patch, using a sanding paddle

Walk away for a little while at this point, if you want. In a warm, dry house, the 20-minute mud will finish drying pretty quickly.

Check that the whole patch is bone-white and extremely hard. If so, use a fine-grit mesh on your sanding paddle to sand the entire area. Feather the perimeter carefully! Don’t scar the old paint and drywall around your patch by being too aggressive.

If everything goes according to plan, you have a well-blended patch. Finally you’re ready for primer and paint!

Wrap-up

Obviously, there are skills that need to be practiced in order to make this process routine. But, drywall mud is really pretty forgiving.

Remember, you can do as many coats as you like. Just use smaller amounts of mud for each subsequent coat. And ALWAYS be careful with the heat gun.

With twenty-minute mud and a few drywall tools, you can to patch superficial drywall damage in record time!

How Thick Can Sheetrock Mud Be?

Professional drywall tapers make the process of mudding drywall look easy. However, it’s a technical process that requires skill and knowledge to do correctly, so your drywall looks its absolute best. Sheetrock mud is an excellent tool for renovating or fixing your walls, but how thick should you apply it?

Sheetrock mud can be as thick as 4.72 inches (12 centimeters). However, you generally want the mud to be as thin as possible while still covering all screw heads and butt joints.

The rest of this article details the ideal thickness of Sheetrock mud, what to do if you have too thick of a coat, what Sheetrock mud is, when to use this substance, and how to mud a wall. If you have a wall that needs renovation, keep reading to get the best results doing the repairs yourself.

What’s the Average Thickness of Sheetrock Mud?

If you’re fixing or renovating your walls, you’ll need to apply a joint compound called drywall mud. If you use it correctly, the mud will dry quickly, and your drywall will look smooth and seamless.

The average thickness of Sheetrock mud is about a quarter of an inch (0.64 cm). However, you can apply it up to a thickness of 12 centimeters (4.72 in). It would be best to keep it flush with your walls, so the thickness may vary depending on the spot.

In general, you’ll want to apply the mud in the thinnest layers possible.

When using Sheetrock mud along the joints, you’ll want to make the mud flush with the face of the drywall. When using it on screw heads and butt joints, you also want a thin layer, but you need to make sure the tape is completely covered.

What Do You Do if You Put Too Much Mud on Your Drywall?

If you put too much mud on your drywall, you can fix the issue by sanding it with sandpaper or a wet sanding sponge. All you have to do is wait for the joint compound to dry, then sand down the bumps and bulges.

You can sand the wall using simple sandpaper, such as this Verones 90 Piece Sandpaper Set (available on Amazon.com). This package comes with multiple grits, so you’ve got everything you need in one box. It’s also durable enough for the job and has a high service life.

If you do have to sand down Sheetrock mud, there will be a lot of dust, so make sure you have a respiratory mask to avoid inhaling the dust.

A better option than sandpaper is to use a wet sanding sponge, such as this Onarway Sanding Sponge (available on Amazon.com). These sponges come in a 10-pack with different courses and grits, last long, and provide more polish than regular sandpaper. Additionally, using a wet sanding sponge results in less dust, so there’s less risk of inhalation.

If you use too much Sheetrock mud and don’t sand it down, you’re going to get cracks in your drywall. Cracks can also occur if you don’t wait until the first layer of joint compound is completely dry before applying another layer.

What Is Sheetrock Mud?

Sheetrock mud is quick-setting drywall mud, also called joint compound, that’s good for small patch jobs. Sheetrock is a brand that makes drywall mud that has become increasingly popular over the years.

Quick-setting drywall mud comes in a powder in plastic-lined paper bags, preserving the freshness and keeping any moisture out.

Hot mud is mixed with hardening agents to make this fantastic joint sealer. Then, it is sold in packages according to how long it takes to harden.

This mud is perfect for drywall installation since it is an ideal material to seal up paper joint tape, fill joints, top paper and mesh joint tapes, and repair holes and cracks in drywall and plaster.

This mud sets because of a chemical reaction, unlike other joint compounds that rely on water evaporation.

Sheetrock brand mud is a ready mix drying type joint compound with a hard-finish surface that can be applied by hand or with a mechanical tool. It would be best to store this mud at 55 to 95 degrees Fahrenheit (12.78-35°C) in a dry location. When you store it properly, it has a shelf life of up to nine months.

When To Use Sheetrock Mud

Quick-setting mud is best for small patch jobs, jobs you need to get done quickly, or jobs when you need to apply multiple coats on the same day. Sheetrock mud, in particular, is best for skim coating, embedding tape, and filling and finishing.

You can buy US Gypsum All-Purpose Joint Compound (available on Amazon.com). This mud is an all-purpose mud, so you can use it for any joinery purposes, but it’s perfect for sheetrock!

You can also get Sheetrock Topping Joint Compound on Amazon.com. Topping compounds are best to use after applying two coats of taping compounds to a drywall joint. This mud goes on smoothly, has a strong bond, and reduces sanding time significantly.

The Wall-Mudding Process

Mudding a wall can be intimidating. However, I’m here to help you make the job simple!

So, let’s break the wall-mudding process down into some simple steps:

Cover the floor to prevent Sheetrock mud splatter. Mudding can get messy, so make sure you protect your floor.
Pre-fill any gaps using a setting compound. Using a setting compound makes the surface smoother, which will help you get as thin a layer as possible when using Sheetrock mud. Let the compound harden before you proceed with applying the joint compound.
Apply a coat of Sheetrock mud to screw indentations and joints. When you fit drywall panels together, the angles form an indentation, so you’ll need to use the sheetrock mud to fill these indentations.
Cover the mud with tape. This process, called “bedding,” will keep the mud looking smooth and prevent it from shifting as it cures.
Tape inside corners and apply mud to outside corners. Be sure to wipe any excess mud from the walls every step of the way.
Mud any butt joints. Butt joints occur when you fit untapered ends of drywall together. Make sure you only use as much mud as is necessary. However, the mud layers will likely be thicker at these points than anywhere else.

If this process seems completely overwhelming, you can invest in the help of a professional.

Conclusion

Sheetrock mud is an excellent tool for renovating and repairing your walls, especially if you’re in a hurry. Luckily, it’s pretty easy to use, too! If you don’t apply the mud too thick, your walls will look like they’ve been professionally done at a fraction of the price and in less time.

Arrangement of curved gypsum board boxes, “peninsulas”, “lakes” and “streams”

If you install not a straight PNP profile as a ceiling guide, but a notched and curved one, then you can make a box of arbitrary shape (Fig. 168).

Fig. 168. Curvilinear drywall box

To obtain profiles of the “snake” or “zigzag” type, a conventional PNP profile is used, in which the side shelf and back are cut with scissors, after which the profile is bent (Fig. 169). The cuts are made in increments of 50 to 150 mm, depending on what radius you want to bend the profile to. A step of more than 150 mm allows you to get a “zigzag”.

Fig. 169. Installation of a curved drywall box

A curved profile is installed on the base ceiling. In this case, it is better to fasten the profile in each incised segment.

Further, everything is done in the same sequence as the manufacture of a conventional box: a drywall strip is attached to the PNP guide profile, to which, in turn, a second PNP profile is attached, incised similarly to the first, and to them there are racks and transverse shorties made of PP profile .

If the short pieces are long, in order to avoid deflection, they are additionally attached to the base ceiling with direct hangers. If the height of the direct suspension installed in the usual U-shaped way is not enough, then the method of attaching the suspension is changed, in this case the suspension is attached to the base ceiling at one of the ends and bent in the form of the letter G. For one fastening of the transverse profile to the base ceiling, two G are installed -shaped suspension (on both sides of the profile). For two or more fasteners, one L-shaped suspension is installed, but they are fastened alternately – either on one or the other side of the profile.

There are several ways to bend drywall along a curved profile.

1. Dry fold.

If the radius of curvature of the guide profile is large, then you can try to bend a strip of drywall onto it without any preliminary preparation. Attach a strip of drywall to the guide profile and screw it with a self-tapping screw in the middle of the profile, then, bending the drywall onto the profile, fasten it in 150 mm increments, driving the “wave” to the ends of the profile.

2. Dry fold with undercut.

If, using the first method, you overestimated the radius of the bend and feel that when bending the plasterboard strip onto the profile, it is about to break, GCR cutting is used.

Cut the stretched side of the gypsum plasterboard strip along a vertically set ruler with a pitch of 50 to 150 mm, cutting through the cardboard and gypsum core to the inner compressed cardboard layer. In this way, with a minimum trimming step, drywall can even be bent into a wheel. True, the structure after such a bend needs continuous puttying, the cut grooves are clogged with putty and it is pulled out, that is, the curvature of the box wall becomes smooth transitions. Fasten drywall to the profile in each cut segment.

3. Wet fold.

Wet gypsum board bends more easily than dry and to a smaller radius. To wet drywall, its surface is rolled with a special roller with needles (piercing roller) or many, many holes are drilled in drywall with an awl or a thin drill and a drill. Pierced drywall is placed on wooden linings and watered until the gypsum core is saturated (stops absorbing water). The raw sheet is attached to the guide profile, bent and fixed. The remaining frame structures are immediately mounted, with the goal of rigidly fixing the GKL before it dries. In general, the same thing is done as when applying a plaster bandage to a broken arm or leg: the plaster bandage is soaked and fixed on the limb, and then dries and fixes the shape that was given to it. The raw drywall sheet fixed on the frame is left to dry completely. No other drywall work has yet been done.

By increasing the dimensions of the box, it is possible to carry out a structure, conventionally called a “peninsula”. And if you make curved boxes around the perimeter of the room, then a “lake” or “stream” will appear in the middle part of the ceiling. Using this method of arranging a simple box, you can implement the most daring design decisions (Fig. 170).

Fig. 170. This method can be used to produce not only arched and wavy boxes, but also ceiling “peninsulas” and “lakes” of any shape

The purpose of the site is not to describe design ceilings, there are many beautiful sites and magazines for this. It will be enough for you to look at the photo in order to then do something similar at home without the invitation of construction masters: the described technology for creating boxes is very simple. By the way, it differs from the technologies of the companies Knauf, Rigips and Lafarge, recognized leaders in the production of drywall, it was developed by ordinary builders and simplified to the limit. Simplification of technology does not affect the quality of work. Unfortunately, any gypsum plasterboard ceiling structures attached to the walls and the base ceiling at the same time are prone to the likelihood of cracking in the seams. Therefore, many builders use continuous gluing of structures with fiberglass, followed by puttying.

When installing a box along a wall with a window, it is wise to step back from the corner and not cover the corner formed by the ceiling and wall with the box in order to place curtains or blinds in it. To arrange a box of this design, it is necessary to introduce another ceiling guide into its frame (Fig. 171), and do not make a PNP guide profile along the wall.

Fig. 171. Arrangement of a drywall box with a distance from the wall

Such a box is made according to the same scheme described above: plasterboard strips are attached to the PNP ceiling guides, the bottom guide profiles of the PNP are screwed to them, to which racks and transverse short pieces of PP ceiling profiles are attached.

Similarly, ceiling “islands” of any shape and size are made. With large dimensions of the transverse profiles of the PP, they are additionally attached to the base ceiling with straight hangers, bent in a U- or L-shape. Take the installation step of PP transverse profiles and direct hangers the same as when installing a simple leveling ceiling with perimeter guide profiles.

Fastener for attaching plasterboard to the ceiling. Types, applications

Such a finishing material as drywall provides an opportunity to obtain a flat surface of the ceiling. And if we take into account the cost / performance ratio, it turns out that it is the most economical of its kind. After all, its functionality is not limited to just alignment. Plasterboard ceiling sheathing allows you to hide elements of various engineering and technical systems. In addition, using this material, it is possible to create multi-level complex structures. And in the space between the ceiling and the GKL (hereinafter referred to as the Gypsum Board), experienced home craftsmen, if necessary, place insulation, soundproofing plates and even lighting elements. However, in order for the structure to be characterized by strength and serve for a long time, it is necessary, first of all, to correctly create a frame for attaching this material to the ceiling. We’ll talk about all this.

Mounting methods

Today, there are 3 methods of fixing the GKL to the ceiling.

Using a special adhesive. This option is resorted to in case of extreme undesirability of reducing the height of the ceiling. However, it is fraught with significant difficulties: the average setting time of the glue is somewhere around twenty minutes. It is simply impossible to hold the material with your hands during this time. Therefore, to fix the GKL, you need to take care of a special kind of masts in advance. Another disadvantage of this method of attaching drywall to the ceiling is the impossibility of laying electrical wiring under this material, not to mention other engineering and technical communications. In addition, the level of heat and sound insulating characteristics of the living space itself does not increase due to the absence of an air gap between the gypsum board and the surface to be treated. Basically, the adhesive fastening of drywall is practiced when it is necessary to level the load-bearing walls.
Formation of a wooden crate (see. Fig.).

This method also has disadvantages. In particular, the beams whose cross-sectional side exceeds 40.0 millimeters are actively damaged by representatives of the Hymenoptera order – ants and other pests. And the combustibility of wood requires the processing of the lathing made from it with special impregnation. However, most flame retardants have a shelf life of four years.
The best option is to create a frame for fixing the GKL from a metal profile. The main advantages of this method are: wear resistance combined with durability; fire and moisture resistance; the strength of the metal determines the reliability of the structure; ease of installation.

Even such a disadvantage as a high level of sound conductivity is leveled by placing soundproofing plates, for example, basalt, or mineral wool, between the ceiling and the plasterboard.

As practice shows, in order to assemble a frame from a metal profile, it is enough to have only minimal building skills and a certain set of tools. But an obligatory preliminary step is a careful calculation of the required material, as well as auxiliary parts – these include connectors, the so-called. “crabs” and elements called suspensions.

Types of lathing under the plasterboard on the ceiling

Metal frames that serve to ensure the fastening of drywall sheets to the ceiling are of two types.

Cellular structure. Bearing profiles form a kind of lattice. This design is used most often.
transverse structure. It differs in the location of metal profiles – only in one direction. Plasterboard sheets are fixed on the frame not along, but across. This type of crate is used, mainly by experienced home craftsmen.

There are frames both single-level and multi-level. Ceilings with two or more tiers are characterized by the complexity of calculation and installation. Therefore, to create a project of such a design, it would be advisable to resort to the expensive services of a professional designer. But the unusual, non-standard appearance more than compensates for the costs incurred.

Stages of GKL fixing to the ceiling

The formation of plasterboard ceiling sheathing is a process that includes a number of steps. Let’s consider each of them in more detail.

Getting Started

First of all, you need to take care of the availability of the tool. The home master will need:

painting (chopping or tracer) cord;
a screwdriver or a lightweight drill for screwing self-tapping screws;
level. You can get by with water. But it is better to use a laser level;
grinder, which serves to cut the metal profile of the required size;
a drill equipped with a mechanism designed for impact drilling, or a household hammer drill.

Sketching

After preparing the tool, before heading to a store selling building materials, you need to create a detailed frame diagram of metal profiles for gypsum boards. It should indicate the points of attachment of its elements to the ceiling. Also on the sketch, you need to display places for lamps and channels through which you have to stretch wires for speakers, electrical power cables and a home LAN harness. In addition, it is necessary to provide for the implementation of heat and sound insulation.

To form a frame under the GKL for the ceiling, you will need a guide profile (PN designation), a carrier profile (PP), as well as the above auxiliary parts – suspensions and connectors of a specific configuration – crabs. With the help of the latter, the rails are paired, placed in the longitudinal and transverse directions relative to the central axis of symmetry of the crate. When calculating the required amount of plasterboard and related components / materials, the perimeter of the room to be sheathed and its area serve as the initial data.

The step of marking the places of installation of suspensions is 60. 0 centimeters. To give the multi-tiered ceiling the required reliability, its structure is strengthened by means of vertical racks, as well as jumpers placed in the corners. The total number of elements of each of these types is the same.

Simplified drawing and summary table

When creating a simplified drawing of a frame structure, the use of specialized computer software (for example, AutoCAD) is not necessary at all. It is enough that the image of the elements is clear to the home master himself. If the project provides for two tiers, for each of them you can use different colors with explanatory footnotes. In case of more levels, all of them are drawn separately.

After the formation of a simplified drawing, data on the applied main and auxiliary elements are entered in the table. It should also include information about:

dowels, with which the structure will be attached to the ceiling;
drills for these dowels or self-tapping screws;
self-tapping screws, through which the profile is fastened to suspensions and connecting crabs;
cutting circle (can be universal) for the grinder available.

You also need to remember the need to purchase goggles and a marker for marking on the profile. Buy fasteners should be with a 10 percent margin.

Preparatory work

Preparatory work should be carried out with particular accuracy, since the quality of the structure being created depends on them.

First, the mounting line of the guide profile is marked. This should be done taking into account the required distance between the plasterboard and the ceiling. So, if you plan to:

hide only the electrical wiring under the drywall, it is enough to lower the frame by 3-5 centimeters;
install built-in lighting fixtures, you will need to provide free space, with a height of 8 to 10 centimeters;
hide the elements of the ventilation system, the frame should be lowered by 10 cm-12 cm.

The points drawn on the wall are connected by a strictly horizontal line. To ensure this requirement, it is necessary to use a tracer cord (coated thread) and a level.

Then the installation lines of the guide profile are marked – as a result, a grid should be formed on the surface of the ceiling. Then it is necessary to mark on the ceiling, as well as along the load-bearing walls, places for installing dowels or self-tapping screws.

Hole drilling

To create nests in the ceiling and wall under the guide profile (designation UD) and hangers, an impact electric drill or a hammer drill is used. Wherein:

the tool must be held so that the drill or drill, respectively, are perpendicular to the surface to be treated;
this procedure should be performed, making sure that there are no electrical wiring in the places of future drilling / drilling.

Fastening the guide profile

First, vertical suspensions are fixed. The guideline for performing this procedure is the lines of placement of the carrier profile prepared according to the sketch. The distance / step between adjacent suspensions is about 50.0-60.0 centimeters. The distance from the wall of the first such element and the last is 30.0 centimeters.

Working with a guide profile involves pre-gluing a sealing tape on its outer side. This will lead to an improvement in the heat and sound insulation characteristics of the sheathing structure where it will adjoin the load-bearing wall.

The guide is a UD type profile. It must be fixed on each tier of the structure around the entire perimeter of the working room. Calculation of the required linear footage (designation L _running) is carried out according to the following formula:

L = M×S, where

M is the number of levels in the frame being formed;

S is the perimeter of the sheathed room.

The fastening step using a dowel is usually as follows: 30.0 cm. The distance of the first fixation point of the guide metal profile from the nearest corner is 10. 0 cm.

Forming the crate and fixing the plasterboard

The carrier profile (type CD) is inserted/inserted into the guide with a step of 60.0 cm across the entire width of the working room. The distance from the wall of the extreme such elements, that is, the first and, accordingly, the last, is 10 centimeters. Fastening of jumpers (transverse profiles) is carried out in increments of 60.0 cm, taking into account the placement of the planned lighting fixtures. The dimensions of the carrier profile are 5.0 mm less than the distance between adjacent guide profiles.

The next step is to fix the hangers with self-tapping screws, followed by fixing the guide profiles. Increasing their length is carried out by means of crabs or special extension cords.

To fully understand how the crate is formed on the ceiling, it is enough to study the above figure.

The final stage is the actual fastening of drywall to the frame. Solid GKL are mounted in a perpendicular direction relative to the longitudinal axis of the guide profiles. Fastening is carried out using self-tapping screws. Their heads should be recessed into the material by about 2-3 millimeters. Docking of sheets is carried out in the middle of the guide profiles.

Helpful hints

So that there are no complaints about the quality of drywall sheathing, it is worth listening to the recommendations of professionals.

Lines with smooth bends are made using a special arched profile, which is distinguished by the presence of cuts on the walls. But he cannot be a bearer. This factor introduces certain requirements for the creation of the structure. In particular, in places where arched and load-bearing profiles are connected, additional suspensions should be installed.
The fastening of the GKL on the formed frame must be started from the window opening of the room.
In real life, there may be significant deviations of the lines forming the room from those established by building codes. This is manifested in the fact that the angles between adjacent walls or between the walls of the working room and the ceiling are not equal to 90 °, the ceiling overlap is not in the same horizontal plane, etc. In the case when the ceiling height “jumps”, suspensions subject to adjustment by means of threads should be used.
Using a laser level significantly speeds up the marking procedure. In case of absence, it can be rented – that is, for rent. The cost will pay off the time saved and the pleasure gained from working with high-tech professional equipment.

Conclusion

With strict adherence to the instructions, the creation of a plasterboard ceiling is possible even for people who have only basic building skills. As a result, high quality of work and significant cost minimization will be achieved.

AQUAPANEL

Aquapanel is a sheet finishing material. The basis of the aquapanel is cement, reinforced over the entire surface with a construction fiberglass mesh. Aquapanel is completely moisture resistant material. Aquapanel is produced for interior and exterior decoration. The aquapanel for internal works is applied to damp rooms. The walls and facades of the building are lined with aquapanel for outdoor work.

REINFORCING TAPE

Reinforcing tape is a special roll material designed for gluing corners (internal and external) of plasterboard walls and structures, as well as joints of plasterboard sheets. Reinforced tape is an essential material when working with drywall.

ARCHED gypsum board

Arched gypsum board is a flexible gypsum board, 6 mm thick, for producing curved, curved surfaces. Arched drywall is reinforced with fiberglass, which allows arched drywall to be bent without a “wet” bending process.

Gypsum (from the Greek gypsos – lime, chalk) is a mineral, the scientific name is aqueous calcium sulfate. Gypsum has a layered crystal lattice structure. Pure gypsum, without impurities, has no color and is absolutely transparent. In the presence of impurities, gray, yellow, pink, brown and other similar colors are added to the color. As a building material, gypsum is widely used to produce binders, for the manufacture of gypsum, gypsum concrete products, finishing materials, such as drywall, ornamental (selenite) and facing stone, gypsum concrete. Gypsum is also used in the production of enamels, paints, and glazes. Gypsum passes air well, otherwise it can “breathe”. It is chemically neutral, does not smell sharply and does not contain toxic substances. A distinctive feature of gypsum is its absolute non-combustibility and high heat-insulating ability.

GYPSUM PLASTER

GYPSUM PLASTER is a dry mortar based on gypsum with special chemical additives. Gypsum plaster is used in construction to level walls and ceilings for subsequent wallpapering or high-quality painting. Gypsum plaster dries quickly, is technologically advanced in work and, with certain skills, can serve as a finishing layer for preparing walls.

Gypsum fiber sheet (GVL)

GYPSUM FIBER SHEET (GVL) is a high quality building and finishing sheet material made of building gypsum and paper fibers. GVL sheets are used to increase the fire resistance of load-bearing floors, partitions, wall and ceiling cladding. A gypsum-fiber sheet is made moisture resistant, its name is GVLV, it is used as a floor element. Moisture-resistant gypsum-fiber sheet (GVLV) is specially impregnated to prevent destruction under the action of moisture. As an element of a dry floor screed, the gypsum fiber sheet is produced with special edges with edges for assembly.

GYPSUM FIBER

Gypsum fiber – same as Gypsum fiber sheet.

Drywall

gypsum board – This is a composite building material. Drywall is produced in sheets with a length of 2.5 to 4.8 meters, with a width of 1.2–1.3 meters and a thickness of 8 to 24 mm.

The base of a drywall sheet is called the core. The core is made of gypsum, and the core is lined with dense but thin cardboard in several layers. To achieve the desired characteristics of the gypsum core of drywall, such as strength, elasticity, density, special chemical components are added to the gypsum core. The lining cardboard plays the role of a reinforcing frame. In addition, cardboard plays the role of a base for applying any finishing materials (plaster, wallpaper, paint, tiles). Drywall is non-combustible and fire-resistant material, while it is both hard and flexible. Drywall is environmentally friendly, has no toxic components and does not have a harmful effect on the environment, which is confirmed by hygienic and radiation certificates. Drywall has good soundproofing and energy-saving properties. It absorbs moisture when it is in excess and releases it when the air is too dry. The last important quality of the material is called the “breathing” of the material and is taken into account when finishing indoors. Also, drywall has an acidity similar to that of human skin. These last two properties allow you to regulate the microclimate of the premises in a natural way, creating a favorable microclimate for humans.

Vinyl-Coated Gypsum Board

VINYL-COATED GYPSUM BOARD – These are plasterboard finish panels with a decorative face finish. These panels are classified into paper-based PVC (polyvinyl chloride film) coated panels called Isoplen; panels with decorative coating “Pletex”; panels coated with PVC decorative film PDSO or PDO; panels coated with PVC material “Devilon”.

Gypsum boards

GYPSUM SHEETS is a type of finishing material. Both standard GKL and moisture-resistant sheets – GKLV and fire-resistant sheets – GKLVO are made. All types of sheets of various thicknesses and sizes. Substances that destroy fungi are introduced into the GKVL sheets; these sheets are used for finishing bathrooms, bathrooms and kitchens. Fire-resistant sheets are used for finishing various air ducts, chimneys and shafts.

GKL

GKL – plasterboard. This is a sheet building material made of gypsum (core) and cardboard. Used for fast and high-quality interior decoration. GKL have good soundproofing and refractory characteristics.

GKL – standard drywall sheet. It is used for interior decoration in rooms with normal humidity. GKL standard is suitable for finishing the ceiling, walls and easily erected partitions. GKLV is a moisture-resistant drywall used in rooms with high humidity. Moisture resistance of drywall is achieved by special additives, they prevent the penetration of moisture. Knauf fireproof drywall sheet is used for fire exits and protection of structures from open flames.

D

Dowels

Dowels are sealing devices for secure fastening of screws, nails and screws in building structures (walls, ceilings, floors). Plastic dowels have replaced the well-known wooden plugs, revolutionizing fasteners. The dowel, made of polymeric materials, when inserted into the hole, is clamped by the expanding forces that arise when it is screwed, while the fastening reliability does not change with time. The correct selection of the drill and fastener for the dowel is important.

Dowel – nails

Dowel – nails are long plastic dowels complete with knurled or threaded nail-shaped screws. Dowel-nails are designed for mounting structures in masonry without voids and concrete, by hammering. Available, dowel nails with or without a hat, the kit may include plastic or metal dowels. Fastening with dowel-nails is reliable, and the metal dowel-nail is fireproof, and is successfully used in the installation of false ceilings made of plasterboard and other structures. During installation, the dowel with a nail is inserted into a hole in the wall, through a fixed rail, then the nail is hammered.

Zh

Sheet metal

Sheet metal for the manufacture of mounting structures (profiles) for plasterboard finishing. Tinplate is cold-rolled annealed sheet steel up to 0.32 mm thick. To protect against corrosion, protective coatings are applied to the metal surface. The best protective properties are white (tinned) tin coated with a layer of tin. A protective layer is applied, tin by the hot method (hot tinned), with a layer of 1.6–2.5 microns thick and by electrolytic deposition, with a tin layer of 0.34–1.56 microns. For work with drywall, the use of unprotected profiles is not recommended. It is also not recommended to use profiles coated without tin (electrolytically chromium-plated coatings, with a protective chromium layer thickness of 0.01-0.05 microns, with a layer of epoxy-phenol varnish 3-8 microns thick, this design quickly collapses and corrodes).

Z

Filling putty

Filling putty is a gypsum-based putty for interior work, designed for finishing surface leveling, sealing cracks, and also filling joints between sheets of gypsum boards. Putty is used for the following bases: plastered surfaces, drywall, GKVL sheets.

Sound insulation tape

Sound insulation tape (sealing tape) is a strip of rolled material 30 meters long and 3 mm thick, made of elastic polyethylene foam (isolon) with a closed cell structure. For ease of installation, one surface of the tape has an adhesive layer. The soundproofing tape has good sound insulation from impacts, is easy to cut and glues well, is durable, resistant to fungi, ultraviolet (solar) radiation. Maintains elasticity from -80°C to +100°C.

K

The quality of drywall work

The quality of drywall work largely depends on the finish of seams and joints. If the sheets are glued, then it is better to seal the joints with the same mastic on which the sheets are glued. When mounting the sheets on the frame, the joints are sealed with gypsum putty with preliminary gluing with mounting tape.

L

Sealing tape

Sealing tape (Dichtungsband) is a polyurethane or foam-rubber self-adhesive tape for gluing rails and rack profiles for drywall to the outside of shelves to improve sound insulation and reduce thermal deformations. Tape is a mandatory material used when working with drywall.

M

Drywall hammer

Drywall hammer, special hammer model with rubber handle, if not available use 200g carpenter’s hammer.

H

Special knife

Hand tool with retractable blade. The visible, triangular cutting edge is used to cut drywall sheets. Also for these purposes, a corner carpenter’s knife or a sharp shoe knife is suitable.

Metal shears

Hand or electric tool used to cut metal profiles for plasterboard constructions.

Hacksaw

Hand tool with interchangeable blades used for cutting drywall profiles.

O

Chopping cord

Tool for marking the surface when working with drywall. The chopping cord should be elastic, not too stretchy, not too thin, so that the broken marking line is clearly visible on the surface.

Plumb bob

Plumb bob is a tool for checking the verticality of drywall during installation. An elementary plumb line is a cord, at the end of which a weight is attached. A cylinder with a tapered end or a cone is used as a load. A loop is made at the other end of the cord for mounting on a wall, ceiling or finger. The color of the cord is chosen to be noticeable in order to be clearly visible against the surrounding background. The plumb line can be combined with a protractor to accurately determine the angle of deviation. By using a plumb line, a level and a goniometer in combination, it is possible to make vertical markings for plasterboard structures with the necessary accuracy.

Tongue-and-groove slabs (PGP)

Gypsum tongue-and-groove slab is a building material in the form of rectangular slabs. Plates can have grooves and ridges for high-precision joining during installation. The surface of tongue-and-groove slabs has a smooth and even surface, which can exclude additional plastering. Used tongue-and-groove plates for interior partitions. There are moisture-resistant tongue-and-groove plates for use in wet rooms. PGP have good soundproofing characteristics, high fire resistance and this differs from foam blocks.

Hammer drill

Hand-held electric tool. Powerful impact drill with standard options: multi-speed gearbox, impact function, reverse – reverse, sometimes, electronic speed control. The power of household hammers ranges from 500-1000 watts. The rotary hammer easily copes with drilling holes in concrete, brick, etc.

The rule is a hand tool in the form of a long, even aluminum profile truncated on one side. Used when working with drywall for cutting it and sometimes for plastering work.

Punch – a special hand tool for punching holes in metal profiles for plasterboard in order to connect them.

R

Drywall cutting

Drywall cutting is done with a sharp knife, saw or strip cutter. After cutting through a sheet of drywall, the sheet is broken perpendicular to the notch or cut. To process the edges of the cut drywall, a peeling planer or a coarse-grained skin fixed on a wooden block is used. To remove the chamfer under the putty, an edge planer is used. When cutting drywall, it must be taken into account that the thinned edge of the drywall always joins with the thinned edge, and the cut edge with the cut one. If it is planned to putty the seams between sheets with reinforcing tape, a chamfer of 45 ° is removed on the cuts of the plates (this is a third of the sheet thickness). If it is planned to putty without a reinforcing tape, the chamfer is removed at 22.5 ° (this is two-thirds of the sheet thickness). It is better to cut the drywall sheet in height from above. In practice, the even factory edge of the sheet from below does not collapse when installed on the holder during installation. Apertures and holes in drywall structures are cut already in the finished skin.

Metal T-Tier

Metal T-Tier is a large-format measuring tool used for marking drywall sheets.

Tape measure

Tape measure flexible measuring tool for marking out drywall.

Self-tapping screws

Self-tapping screws is a colloquial name that has become a trade and professional terminology. Self-tapping screws are two types of fasteners: self-tapping screws and screws. The name of the fastener is based on the principle of fastening, the screw cuts its own thread. Self-tapping screws are used in mechanical engineering and when screwed into metal, due to their hardness, they create threaded grooves. This allows you to repeatedly screw in and out the screws, as in a nut. In the same way, self-tapping screws are fastened in the thickness of wood, drywall. To work with drywall, there are self-tapping screws that fasten metal to metal and drywall to metal frame.

Falcon

Falcon 40cm x 40cm light sheet metal with handle attached perpendicular to it. The falcon serves as a kind of tray for mortar during plastering work.

Special putties

Special putties for sealing joints between plasterboard or gypsum fiber boards. These putties are characterized by increased elasticity and a high coefficient of adhesion to the base on which they are applied. Putties are used as finishing putties, to prepare plasterboard surfaces for final finishing (painting or wallpapering). Special putties are more suitable than others for complex curved surfaces.

Subform

Subform is a peeling planer for edging drywall sheets.

Superfinish putties

Superfinish putties High quality putty materials for very fine finishing of all surfaces.

T

Grater

Grater is a tool for fixing abrasive meshes and grinding putty surfaces.

Third Arm

The Third Arm is a pole with a crossbar or platform at the end to support drywall sheets as they are attached to the ceiling.

У

Angle grinder

Angle grinder is a hand-held electric tool commonly called a grinder. With the help of a “grinder” they cut metal profiles and sheets, a corner, clean the seams after welding and perform a number of other related works. The replaceable cutting discs of the angle grinder allow you to process both metal and stone.

Building levels

Building levels, drywall tools. Alcohol, water and laser levels are used.

Ф

Finishing putties

Finishing putties are used for sealing cracks, scratches and other small defects and for final leveling of the surface. Apply in a thin layer no more than 1 mm. Putties applied up to 0.5 mm are called superfinishing.

Ш

Spatula

Spatula (from German: Spatel) is more often a metal, plastic or rubber tool, in the form of a spatula, used for applying fillers. When working with drywall, steel spatulas are used, with a narrow and wide working part, with plastic or wooden handles. Narrow spatulas 100 mm are needed for sealing joints with reinforcing tape, wide ones of 200 and 250 mm are used for puttying the entire surface of plasterboard structures. There are special spatulas for finishing external and internal corners of structures.

Putties, putties

Putties, putties, dry or pasty building materials, for leveling (puttying) surfaces before applying finishing materials to them. Putties contain film-forming materials, fillers (chalk, barite, talc, etc.) and pigments (zinc white, ocher).

A distinction is made between oil, varnish and adhesive putties, which are based respectively on drying oils, varnishes and natural adhesives. Due to the low content of film-forming materials (5-12 times less than the content of fillers and pigments), putties cannot ensure reliable adhesion of covering layers to putty without a primer layer. Spatulas are used for manual application of putties. Pre-prepared putties can be applied by pneumatic spraying. The thickness of one layer of putty reaches 300 microns. The dried layer of putty is well polished with an abrasive sandpaper or mesh. In construction, mainly glue and oil putties are used.

Screwdriver

Screwdriver is a hand-held electric tool, a kind of drill. It is used in various installation works with drywall. Using a screwdriver, a self-tapping screw (self-tapping screw) quickly and reliably fastens a drywall sheet to a wooden or metal frame, without pre-drilling. The screwdriver has several modes of rotation. Available in various modifications, most screwdrivers are battery operated.

Stretch ceiling or drywall – which is better. Pros and cons, where is it better to install

Ceiling decoration in shaping the interior of any room plays a key role. Properly selected materials and visual effects allow you to create the desired style, hide the shortcomings of overlap or communication, focus on important details, emphasize the taste of the owners. The required qualities are formed by a combination of the characteristics and properties of the front coating and the internal structure in combination with lighting and backlighting. Two technologies provide the most opportunities for implementing various ideas. At the heart of one of them is a stretch fabric, and the other is drywall. Let us consider in detail which option is better, having studied their features, common points and differences.

What do they have in common?

The popularity of drywall and stretch fabrics for ceiling decoration compared to other methods is due to an important common advantage. They allow you to form a perfectly flat surface, hiding communications and overlap flaws. There is no need to use mortars, primers or thick layers of plaster. All work is carried out almost “dry”.

The front material is fixed on special profiles that form a frame with the necessary internal technical channels. Wiring is mounted inside, fasteners for lamps, lamps or chandeliers are placed. With such important similarities, technologies have significant differences that provide available features, cost and other aspects.

Stretch ceiling

A stretch ceiling is a structure based on a thin canvas fixed with harpoons or other special fixtures on aluminum or plastic profiles mounted on the ceiling around the perimeter of the room. This material is the main element that provides attractiveness. Thanks to good tension, the canvas forms a perfectly smooth surface.

Harpoons or other fasteners are located on the support profiles, with the help of which the required height and geometry of the facing material are set. The height is determined taking into account communications, defects in the base and the lighting system (backlight), assuming the presence of space sufficient to accommodate wiring, ceiling lamps, other equipment and internal parts.

Benefits

Easy to install . Installation of a stretch ceiling is carried out within 3-4 hours. Such a period can be shocking in the face of the fact that it takes several days to install plasterboard structures. At the same time, it is quite difficult to perform high-quality work on your own. Especially if there is no heat gun, relevant skills or experience with profiles, lighting systems.
Minimum dust and contamination . The installation of the tension structure does not involve complicated preparation or “wet” steps. All irregularities and defects are hidden behind the canvas. You need to remove only those parts of the old coating that can break off and damage the film from the back.
Moisture resistance . PVC stretch fabrics protect the base from moisture. Due to this, they are indispensable in the arrangement of rooms with high humidity, where there is evaporation, a lot of condensate forms. They also act as an additional protective barrier when the room is flooded from above. Water collects on the canvas, protecting furniture and other items from getting wet. This is an important advantage for apartment owners in high-rise buildings.
Finish coat not required. Color, texture, visual effects – all this is selected at the stage of order formation and project development. Additional work after stretching the canvas is not required. This greatly speeds up the installation process.
Large selection of . Unlike drywall, stretch ceilings can create unique visual effects. The canvas can be transparent, have an additional drawing or photo on the back, and even a three-dimensional illustration that will be visible when the lighting is turned on. In addition, this technology has a large selection of shades and textures. The surface of the ceiling can be matte, satin, glossy, fabric or a combination of several canvases of different types.
Easy care . To care for a smooth surface, you do not need to use special tools. The canvas is wiped as it gets dirty with a damp cloth.
Unique combination with lighting . The ability to select transparency creates unique conditions for creating an original interior and all sorts of effects in combination with lighting. You can, for example, imitate the starry sky, clouds, lightning and more.
Durability . The service life of high-quality canvases exceeds 15 years. During this time, they do not lose color, pattern clarity, texture or other properties, and do not sag. Problems begin only when the rules of operation are not followed.
Takes up minimal space . You can stretch the canvas at a distance of 3-4 centimeters from the ceiling. Due to this, a noticeable decrease in the level of the ceiling is excluded. This is an important advantage for apartment buildings and private buildings with low wall heights.
Versatility . Stretch ceilings can be used for decoration of residential, commercial, administrative and other premises. A large selection of types and textures of canvases with different characteristics allows you to select the best option, taking into account humidity, temperature changes, and other operating conditions of the room. Eco-friendly material is allowed to be used for decoration of children’s rooms and medical and recreational facilities.

Drawbacks

With a large list of important advantages, stretch ceilings also have disadvantages. They cannot be called critical, but they can play a key role in choosing the material for facing a particular room. Therefore, these points should always be taken into account. The disadvantages include:

Low puncture resistance . Thin fabric is easy to pierce with sharp objects. Due to good tension, even a tiny cut can “spread” and render the coating unusable. These problems make it possible to solve materials with a fabric structure. It is formed from many intertwined threads. This solution increases the resistance to cuts and temperature fluctuations, but at the same time makes the canvas permeable to moisture.
Mechanical deformations . Materials are not designed for loads. It is forbidden to put foreign objects on a thin canvas. The thin film will sag. Because of this, the base must be prepared before work, removing particles of easily peeling old finish from the floor.
Not repairable . If the canvas is damaged, it will have to be replaced completely. The material is not repaired with overlays or other means. At the same time, the presence of a ready-made frame makes the replacement quick and much cheaper compared to installing a new design.
Fear of high temperature, fire . When the wiring ignites, the material begins to melt. The problem is partially solved by more expensive products with special impregnations or coatings. Plus, electrical work should be trusted exclusively to professionals.

Plasterboard ceiling

A plasterboard ceiling is a suspended structure that forms an ideal flat surface, allowing you to equip several levels for zoning and creating visual effects with a combination of different fixtures and colors. It is based on a frame made of metal profiles fixed on the ceiling and walls. The technology is similar to the alignment of walls. The difference is that here you need to work in a horizontal plane. Drywall sheets play the role of a finishing base on which a facing layer is applied, more often – wallpaper or paint. The joints between the sheets are filled with a special solution, which excludes visible and tactile seams at the end of the work.

Benefits

Can be used at all temperatures . The material is not affected by high temperatures and their fluctuations. If there are no sources of evaporation or humidifiers in the room, the design will retain its original appearance all year round even without heating.
Mechanical resistance . Durable sheets are resistant to moderate mechanical stress. They are elastic enough to form a rigid base for cladding with various finishing materials. Drywall is quite difficult to damage. At the same time, sharp objects are still able to leave a noticeable mark on the surface.
Repairability . Against the background of a stretch ceiling, this advantage seems quite significant. Unlike a competitor, in case of damage it is not necessary to replace the entire coating. An area with a cut or gouge is easily repaired with a small insert. In some cases, repairs may require the replacement of one or more sheets.
Great versatility in creating three-dimensional shapes . The boards are easy to cut and, when wet, can be shaped into complex shapes. Joints are treated with a gypsum-based solution. As a result, you can create exclusive design forms, arches. The required geometry is set by a steel frame and harpoons that hold the material, which imposes certain restrictions.
Enhanced acoustic performance . Multi-layer structure – gypsum inside and cardboard sheets outside form a good sound insulation. Drywall can be combined with additional materials, which will increase the effect several times, providing additional thermal insulation. Stretch fabrics in this regard lose significantly due to the thin structure.
Flame resistant, no toxic emissions . Unlike polymer films, drywall does not melt even in direct contact with fire. At the same time, it is not capable of completely protecting against fire, like a stretch fabric.

Drawbacks

The disadvantages of plasterboard-based ceilings are more significant compared to tensile structures. Therefore, they are used for cladding less often.

Permanent installation . The installation of a plasterboard ceiling takes from 2 to 5 days. The exact time depends on the amount of work and skills. You can install the structure yourself, but there is a high risk of damage to the sheets during installation due to the large size. Against the background of a stretch ceiling, such a flaw is quite serious.
Room pollution . Working with sheets containing gypsum is accompanied by the release of a large amount of dust. Therefore, at the time of installation, you will have to free up the room as much as possible and cover all the furniture with a protective film. The likelihood of contamination is also high at the stage of leveling, sealing the seams and applying the finishing facing material.
Takes up a lot of space . The canvas can “reduce” the height of the ceiling by 3-4 centimeters, and drywall – at least 8 centimeters. This difference is due to the complexity of the frame and the relatively large thickness of the plates.
Requires finishing . Upon completion of the installation of the sheets, the seams must be sealed. For this, gypsum mortars are used. Only after complete sealing is the facing layer mounted in the form of wallpaper or painting.
Drywall is “afraid” of moisture . When flooded from above, the material intensively absorbs water, soaks and collapses. As a result, the whole room will not only be wet, but also heavily soiled, covered with a solution of gypsum mixed with finishing materials.

Price

Comparative calculation of the cost of arranging ceilings is a complex process, especially without accurate initial data. At the same time, there is a significant difference that has a key influence on the formation of prices – labor costs. For example, a PVC stretch fabric is mounted by 2-3 specialists using a heat gun. With the installation of profiles and lighting, this can take 3-4 hours. Work with drywall by a similar team lasts several days. Even with self-installation and saving on labor, the purchase of materials for a stretch ceiling will cost several times cheaper.

The price of a stretch ceiling largely depends on the quality of the canvas and the effects. By choosing the simplest options, you can significantly reduce costs without sacrificing quality, reliability and durability. Plus, when using drywall, you need to additionally take into account the cost of the front coating – paint or wallpaper.

Which is better: stretch or plaster ceiling?

Comparing the negative and positive aspects of ceiling cladding technologies, it is easy to single out the undisputed favorite – stretch fabrics. A variety of materials allows you to equip bedrooms, bathrooms, kitchens, vestibules, balconies, offices and other premises. Visual effects provide unique opportunities that drywall is absolutely not capable of. Plus, the installation of tension structures takes a minimum of time without preliminary preparation of the premises.

You can get acquainted with the variety of available materials in the catalog of the 100 ceilings store. We have a large selection of quality fabrics from leading manufacturers. Experienced managers are always ready to answer questions, help with the choice.

an easy way to tear off old canvases from gypsum board

Pasting surfaces from gypsum plasterboard is carried out with various roll materials using a variety of techniques. Sometimes, if necessary, remove wallpaper from drywall, there are numerous difficulties. The problem is that the base is easily damaged, this requires a special approach. For each situation, an individual solution is chosen.

Removing wallpaper from a puttied surface

GKL boards coated with a thin layer of finishing mixture are more resistant to external influences, but due to the fact that pasting is done with different products, the removal method is selected individually.

Paper products

This variation is very popular due to its affordability and ease of installation. To remove such a finish, the following work is carried out:
1. The presence of delamination is determined. Over time, the decorative surface for various reasons may move away from the base, which contributes to faster dismantling.
2. With a knife, the sheets are trimmed and slightly pry off, part can be torn off without any extra effort.
3. Carefully glued areas require a more serious approach using liquid. Water at a temperature above room temperature is poured into the container, a sponge is wetted, the desired areas are processed. An alternative is a spray bottle. The application is repeated 2-3 times so that the coating is well saturated. Next, the edge is carefully pry off with a spatula and the rest of the old wallpaper is removed.
Removal of old paper sheets is usually not difficult, for easier removal the wallpaper is moistened with warm water

Water can be used to remove almost all types of paper materials, the main thing is to minimize damage to the finish layer of putty, which will facilitate surface preparation.

Vinyl sheets

This option has a stronger outer layer, but in most cases paper-based versions are used for gluing walls. Unlike the previous method, perforation of the coating is required. Processing should be minimal so as not to damage the putty and prevent liquid from penetrating the drywall.

Removal technique:
- The outer vinyl layer can be scratched with a utility or utility knife or perforated with a spiked roller. The tool rolls the surface several times, but without much pressure.
  Various tools are used to break the integrity of the vinyl flooring, but in the case of drywall, it is desirable to use either a spiked roller or a special tool with spiked wheels
- A soap solution of ordinary warm water and detergent is applied in several steps. After impregnation of a certain area, the wallpaper is immediately put on and removed.
- Small areas may remain on the surface, which will be easily peeled off if a sponge is briefly applied to them.
This method avoids damage to the cardboard if the putty is damaged.

Paintable non-woven

It is much more difficult to remove such material correctly, especially if there is an additional decorative coating. Just tearing off the wallpaper without serious damage to the base will not work, so you can use the steam method, which allows you to remove well-glued and thick materials.

Note! Such dismantling requires special care: strong heating should not be allowed so that the cardboard does not peel off from the base.

Process diagram:
1. A selected area is treated with a steam generator.
2. The cover immediately slides off and pulls to the side.
3. If it is not possible to peel off a large strip, then a quick temperature treatment must be carried out again.
The steam generator gives a quick result, therefore, when working with drywall, it must be used in short sessions, otherwise the supporting cardboard layer may move away from the plaster

The method of gradual removal of the wallpaper layer is longer:
1. The colored coating is carefully peeled off. First you need to remove areas that easily move away.
2. The remaining places are treated with hot water or steam.
3. The base can have a strong adhesion to the GKL, then it will not work to peel off the layer, so it is sanded and the putty surface is recreated.
Sometimes it is not possible to determine exactly the most appropriate method, in which case several options or a combination are applied, taking into account the best result.

Removing old materials pasted directly onto drywall

Ripping off any wallpaper without an intermediate layer of putty is not an easy task. It is almost impossible not to damage the base in such a situation, therefore, the procedure requires using the most effective method – chemical. To remove old wallpaper, reagents with a special mark are used.

Specialty chemicals are considered very effective in wallpaper stripping, but they tend to have a strong odor and can be toxic

Work is performed with gloves, goggles and a respirator. The agent must be applied to the surface evenly, otherwise the pieces will come off along with the coating. To exclude serious damage to the cardboard, the readiness of the canvases for removal should be checked constantly, and not be guided by the time specified in the instructions.

Tip! You can also treat the surface with ordinary wallpaper glue: it will impregnate the canvas and pull it away from the base.

What if the wallpaper cannot be removed without damaging the drywall?

This problem occurs when the gypsum board coating and the glued sheets are firmly bonded. In this case, the decorative layer can be removed only with a serious violation of the structure. Such a defect, especially with large-scale damage, will significantly reduce the reliability of the walls.

It is extremely difficult to recoat the wallpaper, so the following procedure can be used:
1. A wide trowel is used to remove the top layer. The blade is placed at a slight angle to the surface, almost parallel, the treated areas are slightly wetted and quickly peeled off without excessive pressure, so as not to damage the drywall.
2. Dry sanding and priming. After applying the mixture, the presence of delamination is checked.
3. The surface is covered with a thin layer of putty with high adhesion.
Alternatively, the wallpaper is completely peeled off from the surface:
1. Part of the canvas is pryed off with a sharp spatula, the material is removed with a smooth movement. To avoid severe damage to the GCR, the blade is constantly exposed to difficult areas.
2. Careful priming in progress. A thin layer of putty and a reinforcing mesh are laid on seriously deformed places.
3. The coating is fully processed with the finishing mixture.
Removal of old wallpaper from plasterboard with subsequent reinforcement of the surface

It is taken into account that the methods that are used when it is impossible to remove the wallpaper without damaging the plasterboard do not always provide the desired result. On surfaces with delaminations and voids, it is not recommended to stick artificial stone, brick or tile.

Application of film

Self-adhesive tape can be reflective, plain, with a relief pattern, glossy. On the reverse side, it is covered with adhesive. Different types of film have features that are reflected on the drywall surface depending on the room.

Kitchen. Humidity and temperature fluctuations are always present in the kitchen. For protection and a beautiful finish, drywall can be pasted over with a self-adhesive film. The drywall hood, pasted over with this material, will be protected from grease, dust, moisture. At the same time, have a wonderful modern design. Using self-adhesive film in the kitchenGypsum board boxes are pasted over to match the overall tone of the kitchen, sometimes these products are covered with a glossy monochromatic film. GKL shelves on the wall and drywall niches can be pasted over with a film, thereby protecting the drywall from water ingress on them.
Toilet, bathroom. Excellent protection plus modern design. With a numerous choice of film, a bathroom can be made under the seashore with white sand or pasted over, for example, a plasterboard podium with sea pebbles.
Children’s room. You cannot draw on a self-adhesive film – the pencil does not draw, the felt-tip pen is erased, the paint turns into droplets that can be easily wiped off with a rag. Therefore, plasterboard furniture and walls can be pasted over with self-adhesive film in a children’s style. It will be interesting for the child and at the same time protect from the pranks of the baby. The self-adhesive film fits perfectly into the children’s room
Corridor. In this room, the switch, drywall doorways get dirty the fastest, with frequent washing, the top layer of the finish is erased, and then the drywall itself. When pasting with a film, such problems will not arise. Easy cleaning is guaranteed even when heavily soiled. The self-adhesive film works great in the corridor
The living room has a plasterboard fireplace. When pasting it with a film under a wild stone, a visualization of naturalness will appear. At the same time, the design of the room will be preserved.

Drywall filming tools

In order to stick the film on drywall, you need a set of drywall tools:

Ruler or meter.
Pencil, marker.
Construction knife or good big scissors.
Soft spatula (non-metallic).
Hairdryer or dryer.
Soft cloth, rag.

Tools for applying self-adhesive film
Filming drywall requires time and patience. You need to be careful in measuring and cutting the film. When pasting a large surface (wall or ceiling), you will need an assistant.

Surface preparation

One of the most important steps is to prepare the surface for film gluing.

Surface must be dry. If the drywall has recently been covered with putty on top, it should be dry and cleaned of pebbles and strips left during puttying;
The surface must be free of dust. The best cleaning of drywall from dust is to work with a vacuum cleaner. Because when cleaning the surface with a cloth, small dust particles remain, which will prevent better adhesion;Preparation of the drywall surface for the sticker
If you plan to stick not one type of film, but several, that is, to make the wall combined, then you should make markings and take measurements. As a last resort, you should draw a layout according to which the film will be cut out and pasted onto drywall;
When gluing a gypsum board ceiling, be sure to carefully measure each curve and corner. Glossy film in bright light will show joints, so this should be taken responsibly;
If the film was in a cold room, it must be brought into the room where it will be mounted before installation.

If these rules are observed, the adhesive film will have a long service life.

Installing the film on drywall

Before pasting the film, it is necessary to dry and heat the corners of the surface with a building dryer. After that, you need to do the following:

The plasterboard surface should be coated with a primer and wait for it to dry.
When the roll is unrolled, a gray marking can be seen on the back of the film. The lines are marked for precise centimeter cuts. Gray lines on self-adhesive film
Cut out the patterns with a sharp object so that there are no jagged edges. And also this must be done carefully, because the film under certain lighting conditions can show its joints.
Self-adhesive film imitating brickwork or brickwork must be cut at the seam in the illustration. Self-adhesive film for brickwork
On the cut out piece of film, it is required to detach the paper from the back by 5 cm, no more.
Next, carefully apply the film to the surface along the desired boundaries. When gluing one edge, gradually peel off the paper from the back and glue the film.
The film must be smoothed during the gluing process from the center to the edges. In this case, a soft rag or a special spatula is used. It is necessary to stick the film gradually, smoothing it out
To smooth the film, slightly pressing your hand or spatula against it so that it does not stretch (but it all depends on the quality of the material). The process of smoothing the self-adhesive film with a spatula
If there is a “wrinkle” or air left when applying the film to the plasterboard surface, you should go back and correct the mistake.
If an air bubble has formed after the surface has been completely glued, then a thin needle is carefully pierced and the air is expelled.

As can be seen from the described process, there are no difficulties. You should be careful and not rush. See in the video how to glue the self-adhesive film.

Cover the ceiling with glossy film

Applying the film to a homemade plasterboard ceiling creates a glossy look that reflects the light from the lighting fixtures on the ceiling and creates an imitation of a beautiful stretch ceiling. When creating this surface, accuracy in dimensions and cutting is required, as well as accuracy.
Glossy film

All preparatory work must be done before applying the film. This also includes the careful processing of seams on a drywall surface.
The surface must be coated with a primer mixture before gluing.
The measurements taken from the ceiling are transferred to a film roll and cut out.
Next, the cut section of the film is applied to the ceiling and carefully glued. Here, the film should be smoothed with a napkin. It does not leave micro-scratches visible in the light on the glossy surface.
The air bubble is pierced with a fine needle. The air is expelled, and the film is glued slowly and carefully so that a wrinkle does not appear.
On a two-level gypsum board ceiling, you can apply a combination film gloss plus matt. This will highlight the shiny surface, smooth out sharp corners and make softer edges. Ceiling with glossy self-adhesive film

The combined self-adhesive film can also be used depending on the lighting fixtures. If the backlight is made for zoning the room, then the darker areas are made with a matte film, and the bright section of the ceiling is made with a glossy self-adhesive.

Removing self-adhesive film from plasterboard surface

The film is applied to the surface practically and for a long time. How to dismantle the film from drywall? There are a number of rules for this.

Take hot water and soak the self-adhesive.
Wait a little while for the adhesive to soften.
Next, carefully remove the film with a spatula. Care must be taken not to damage the drywall surface.
If the adhesive does not swell with water, then a blow dryer is required. It softens the adhesive with hot air and the film can be easily removed from the drywall.
