Do I need to plaster drywall? How to cover drywall with plaster: necessary tools and materials. Determining the need for plaster
Quite often, novice home craftsmen wonder what and how to plaster drywall. Let's start with the fact that gypsum board is also called dry plaster.
Why is gypsum board called plaster?
Firstly, with the help of sheets of this material you can level the walls and ceiling, as well as repair plane defects. Secondly, the installation of gypsum boards is not associated with Thirdly, after installing the sheets, the wall becomes even and smooth, which allows you to begin finishing work almost immediately. Some people believe that it is not necessary to bring drywall to perfect smoothness. However, the opinions of experts on this issue are divided.
Do I need to plaster?
If you also wondered whether drywall is plastered, then you should look into this in more detail. Some argue that there is no need to plaster the sheets - this is in vain and takes a lot of effort and time. Other craftsmen claim that the process of applying plaster is necessary when the wall has been subjected to stress and has lost its original appearance.
In general, you can plaster drywall only if it has moisture-resistant qualities. The composition should be applied in several passes, in thin layers, each of which is covered with a primer. To do this, you should use the composition deep penetration, intended for gypsum-containing materials.
Results
Understanding the question of whether it is necessary to plaster drywall is a thankless task. Some believe that a thin layer of putty will be enough, while others argue that plastering the surface is necessary. If you want to achieve an ideal result, then you should carry out similar preparation, the features of which will be discussed below.
Additional recommendations for the drywall preparation process before applying plaster
If you are thinking about the question of how to plaster drywall under wallpaper, then you should also know about the features of surface preparation. Due to the fact that gypsum board is most often installed using screws, indentations and irregularities remain on its surface. Sometimes drywall is bent during installation, and sometimes a needle roller is used to create curved structures. After such an impact, a huge number of grooves remain on the canvases. It is important to eliminate all these shortcomings before gluing wallpaper.
The need to use a primer is due to the fact that it is important to increase adhesion between drywall and subsequent finishing layers. The primer must be applied to every centimeter of the sheathing. For this, a foam roller or wide brush is usually used. You should not wet the sheet too much, otherwise it may become deformed.
After you have figured out the question of whether it is possible to plaster drywall, you should apply putty, which will hide the joints of the sheets and recessed screws. A sickle tape is applied on top of the putty layer. Where the canvases meet at an angle, which can be external or internal, the flaws should be leveled with perforated aluminum profiles, which are applied to the corners covered with putty.
Excess mixture should be removed by smoothing the surface of the profile. As soon as the drywall has dried after applying the putty, it should be primed again in the same way as described above. The surface prepared in this way can be used not only for gluing wallpaper, but also for paste mixtures or dry stone chips made from minerals of different colors.
If you plan to prepare drywall before gluing wallpaper by applying plaster, then the composition will help level out problem areas, such as potholes or dents. This must be done in several approaches; each previous layer should be given time to dry.
If you need to repair small potholes and dents, then the surface is covered with a primer at the first stage, and then a layer of putty is applied, and a little later - a layer of plaster. It must be remembered that the putty layer should not exceed 3 mm in thickness. If the potholes have a more impressive depth, then you cannot do without plaster.
Before plastering drywall, you should familiarize yourself with the technology, which does not recommend hiding frame installation errors with a thick layer of plaster. This will rid the surface of defects, but over time the sheets will not be able to hold the applied layer of plaster. This will cause their deformation and the occurrence of cracks, as well as peeling of the plaster layer. If you have identified fairly large curvatures, then it is better to replace the sheets with high-quality material.
If you are wondering how to plaster drywall, you should know that the material is applied to the surface in a thin layer, and the base is first primed. If we're talking about about granular coatings, these can be factory-produced paste mixtures that are ready for use.
The compositions are applied using a sprayer or trowel; the thickness of the layer will depend on the diameter of the grains. The first parameter should exceed the fractionality by 1.5-2 times. Dry colored stone chips are sprayed onto the surface, which is pre-lubricated with an adhesive composition.
Instructions for applying plaster
If you are also one of the home craftsmen who are faced with the question of how to plaster drywall, then you should know about the peculiarities of carrying out such work. As soon as the installation of the sheets has been completed, their surface must be cleaned of settled dust. An industrial vacuum cleaner copes with this task perfectly. If this is not available, then you can use improvised means. They are rags that are pre-moistened with water.
At the next stage, joints, seams and irregularities are puttied. As soon as this layer has dried, the treated areas must be covered with a leveling layer. Using a primer suitable for plasterboard surfaces, you need to treat the base with it. It is recommended to choose a primer for these manipulations. moisture-resistant plasterboard. Only then can you begin
These works should be carried out at moderate air humidity and temperatures ranging from +5 to +35 °C. The technician should use a respirator or gauze bandage, as well as rubber gloves. After completion of the work, the tool is washed, and the remains finishing material should be tightly closed and stored in a dry place. Sometimes plaster is used to restore a damaged layer.
Plastering the ceiling before gluing wallpaper
If you are faced with the question of how to properly plaster drywall installed on the ceiling, then it is important to familiarize yourself with the technology. For the reason that you will have to spend quite a lot of time under the ceiling, and applying the compositions cannot be called convenient process, you should purchase a roller with an extension for the handle. With its help it will be possible to work at a height of up to 4 m.
We plaster the drywall with our own hands in the ceiling area, scooping the mixture from a container with a spatula. The composition should be transferred to a trowel, and then press the tool tightly to the plane at an acute angle with respect to the surface. The plaster will be of better quality if you use this method without using a sprayer. A dense layer can only be achieved by using a powerful compressor. It is important that the movements be smooth, the direction can be any, the main requirement is that the composition be applied in a thin layer.
If necessary, the trowel must be passed over the surface again. The next batch of plaster is applied without a gap, close to the first batch. The smaller the portions, the smaller the strokes should be, ultimately this will achieve a better effect. As soon as the first layer has dried, you can proceed to the formation of the finishing layer. This work must be carried out with a trowel; there should be more overlapping strokes if you want to get a darker area of the coating. Instead of trowels, craftsmen sometimes use other tools such as textured rollers.
Conclusion
Plastering plasterboard is necessary when it is necessary to hide installation defects and cavities from fasteners, as well as joints between sheets. It should be remembered that plaster is applied only after priming and puttying the surface. Once all the layers are dry, you can move on to the final leveling before wallpapering. It is important to seal the outer corners, which will also be finished with wallpaper.
The solution is applied to the corners in a minimal amount. It is important that it is only enough to cover the plane of the corner. The perforated profile is then applied to the corner and leveled using a building level. If you notice that the corner is sunk, then plasterboard construction was not assembled quite evenly. You can correct the situation by placing more putty under the metal.
At its core, the unexpected question of how to plaster drywall is not a priority, since this material is just a dry type of plasters. It is much more important to decide on the finish in advance, that is, it would be more correct to immediately ask yourself whether it is necessary to cover plaster composition a perfectly flat surface? The answer will be positive if a decorative mixture is chosen as the finishing material.
What should you do before plastering drywall?
Usually, craftsmen or the owners of apartments and houses themselves undertake the complex and painstaking installation of profiles at a level so that in the end, after the sheets of drywall are fixed with screws, a flat surface is obtained. That is, they try to achieve with less labor the same result that is obtained after applying liquid plaster mixture. And if one material is replaced by another, do they need to be combined? Quite if you prefer decorative plaster as a coating rather than paint or wallpaper.
In this case, drywall will play the role of a perfectly prepared, leveled surface, however, given that this material gets wet easily, it is better to take waterproof sheets. And this is the first thing you should take care of before plastering the drywall. The second thing you need is a special deep penetration primer. As for the finishing material, it is recommended to opt for quick-drying mixtures, so that during the hardening process of the coating, as little water as possible passes into the base sheets.

Foundation preparation process
Because it's about doing plastering works, we will assume that we have already installed the plasterboard covering. But before moving on to finishing, you need to carefully prepare the surface. It would seem that the sheets are already perfectly smooth. However, if the sequence of their installation was followed to the smallest detail, the screws must be recessed, and this already creates unevenness. The seams of the joints may not be completely smooth individual parts sheathing, and one should take into account the possibility that a needle roller was used to create the curved structures, which left a large number of notches. All these small surface imperfections should be eliminated.
Preparing drywall for putty - step-by-step diagram
Step 1: Priming
To increase the adhesion of all subsequent finishing layers that will cover the drywall, we take a pre-prepared primer and carefully cover every square centimeter of the sheathing with it. For this purpose, you can use a wide brush or foam roller. Be careful not to wet the sheets too much to avoid warping them.
Step 2: Puttying seams and fastening points
As a rule, putty is sold ready-made, so open the container and take a trowel. Scoop up the mixture in small portions and apply a thin layer both at the joints of the sheets and over the recessed screws, smoothing it well. We put a sickle tape on top.
Step 3: Editing Corners
Where sheets of drywall meet at an angle, internal or external, it is impossible to use putty alone to smooth out the flaws. Therefore, we use special aluminum perforated profiles, placing them on the corners covered with putty. Excess mixture that protrudes through the holes is smoothed over the profiles, completely hiding them.
How to coat drywall?
After the putty has been applied to the prepared surface, the walls (and the ceiling, if you want to treat it too) are primed again in the same way as described above. This is done so that the plaster lays well on the smoothed mixture, which hides all the unevenness. And if you have not yet reconsidered your decision in favor of wallpaper, you can start choosing finishing line-up. You have few options - these can be pasty mixtures with coarse-grained inclusions, or dry stone chips from mixed minerals of different colors.
Plasters with a high liquid content should be applied exclusively to moisture-resistant plasterboard sheets to avoid warping of the sheathing.
Having chosen the first option, you need to prepare a steel trowel with smooth surface and smooth edges or, for more liquid compositions, a sprayer that allows you to apply the mixture in an even thin layer. But what to do with dry crumbs? Everything is simple, first the sheets of wall covering are lubricated with a special adhesive mastic composition, and only then, using a sprayer on the base air compressor, stone grain is applied. However, since it has nothing to do with plasters, we will not consider this option further.
Plastering plasterboard walls with your own hands - what should you do?
So, the surface is completely prepared, leveled, primed, and ahead of us final stage work - covering the walls, and possibly the ceiling, with a decorative plaster mixture. We talked about what it should be like above, so there shouldn’t be any problems with purchasing finishing material, if, of course, it is available in stores in your city. We will need a trowel and a rectangular spatula or a textured roller. Some application techniques require a trowel.
Plastering plasterboard walls - step-by-step diagram
Step 1: If we plaster the ceiling
When applied decorative composition both on the walls and on the ceiling, you must definitely start with the latter, and only after finishing the ceiling, move on to the vertical surfaces. Since it is inconvenient to work under the ceiling, and moving scaffolding or stepladders will take a lot of time, it is recommended to use a roller with a special extension for the handle, which allows you to work at a height of up to 4 meters.
Step 2: First strokes
Using a spatula, scoop up a little mixture from the container and transfer it to a trowel, after which we press it firmly, flat side up, at an acute angle to the surface. Plastering plasterboard walls with your own hands is done with better quality than with a spray (a dense layer is obtained only when using a powerful compressor). Movements should be smooth, you can choose any direction, the main thing is to apply the composition in a thin layer. If necessary, we carry out the trowel again. The next batch of the mixture is applied almost without a gap, close to the first. The smaller the portions, the fewer strokes, and the more beautiful the finish will be in the end.
Step 3: Second Layer
When the strokes of the first layer have dried, you can move on to the second, finishing one. It is applied either with the same trowel, and the more overlapping strokes are made, the darker the coating area will turn out, but if you can simply overlap the lower strokes and small spaces between them, the surface will be lighter. This way you can create entire compositions by playing with halftones. Instead of a trowel, you can use textured roller, applying the composition directly to them and ultimately obtaining not only a uniform, but also a relief coating.
Plaster on drywall can only be applied with a roller from the very first moment finishing works. In this case, you need to roll the textured nozzle directly over the composition poured into a small trough (sometimes rollers are sold along with such trays), and then apply it to the wall in one motion from bottom to top. If the layer applied with a trowel sometimes needs to be processed with a smoothing iron, then after the roller there is no need to smooth the surface, the finish is final. For frescoes, plaster is applied exclusively with a trowel.
Dry leveling of walls allows you to quickly eliminate surface defects and significantly speed up repairs. But it leaves unsightly joints and visible self-tapping screws - so you will need to plaster the drywall. The surface is finished partially (masking the joints), or completely ().
In this article we will look at the main ones for drywall, the features of their choice, as well as the technology for applying them to sheathed walls and ceilings.
How to properly finish plasterboard walls and ceilings
GCR is a simple and inexpensive way to level surfaces. The sheets are attached to a special lathing, which allows for quick processing large areas, mask irregularities, provide additional sound insulation.
Advice: if in the room high humidity, it is better to choose moisture-resistant material.Moisture-resistant sheets have a green-blue tint
Preparatory work
Rough plaster plasterboard boards is performed after applying a primer that will enhance adhesion to the surface. The screws are pre-deepened so that they do not form unevenness, and recesses are eliminated.
Attention: Do not wet the sheets with primer too much, as this may cause them to deform.
Leveling the surface with a starting mixture - plastering plasterboard walls with your own hands
Next is executed Preliminary processing fastening points and seams between sheets. The dowels are masked with a thin layer of the mixture, the joints between the plasterboard slabs are reinforced with a special reinforcing mesh tape and plastered. A spatula is passed across the joints and then along them. After the putty has dried, its remnants are removed by sanding.
On a note: Drywall primer plaster is prepared immediately before application, as it hardens quickly.
Banding joints will protect the surface from cracking
The external corners where the plasterboard sheets meet are reinforced with aluminum perforated corners. Place them on the putty corners and cover with a layer of the mixture on top.
Strengthening the corners before puttying will protect them from deformation during operation.
A plasterboard wall depends on the type of finish. Thick wallpaper can be glued by sealing only the seams between the sheets. For thin fabrics, it is necessary to putty the surface completely 2 times. Drywall plaster for painting is carried out in 2-3 layers.
First, take a small amount of the mixture onto a spatula, transfer it to a trowel and apply it to the surface at an acute angle, spreading it in a thin layer. Movements are made in any direction, the main thing is that they are smooth and uniform.
Please note: there is no need to take breaks between applying the starter and finishing putty- thin layer gypsum mixture dries quickly.
Applying a rough layer of plaster on gypsum board
The finishing layer of putty is applied with the same trowel. The more overlapping strokes are applied, the darker and denser the coating will be.
The last layer of plaster is designed to hide all errors and irregularities that arose during rough processing
After drying, the ceiling and walls are sanded. To do this, use a grater with a sanding mesh, or a sander with a dust suction function.
Advice: When sanding, it is better to use a respirator or bandage to protect yourself from dust.
Sanding will remove any unevenness and prepare the surface for finishing.

Choosing decorative plaster for drywall, which is better
How to finish gypsum board? To give surfaces a relief, decorative plaster on drywall is ideal. It is a paste of a homogeneous structure, or interspersed with small/large grains and stone chips.
Advice: For finishing, quick-drying mixtures are selected, the moisture from which will not transfer to the base sheets.
Specialization: master of internal and exterior decoration(plaster, putty, tiles, drywall, lining, laminate and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, renovations in an apartment or house were done on a turnkey basis with all necessary types works
Let me start with the fact that if you are thinking about the question of how to plaster drywall under wallpaper, then this is not necessary. The only important thing here is to seal the seams and irregularities that exist on the plane.
For the front finish you just need flat wall and nothing more, and the gypsum board represents just such a structure. That is why I propose to understand everything in order: how to level the wall, how to seal the seams and, finally, how to plaster the surface of the drywall.

Table of drywall varieties
So, as I already said, there is no point in plastering drywall, since wallpaper and paint can be applied directly to it. However, it is necessary to seal the seams so that there are no differences.
When leveling surfaces using gypsum boards, there are some nuances that I will dwell on in more detail:
- To hang wallpaper you need a flat surface, and to do this you should get rid of the joints. Most often this is a PLUK edge - a thin type of fold that can be filled with putty;
- during normal installation, the joints are sealed with putty reinforced with PVC tape, which is glued directly to the paper - there is an adhesive side;
- the instructions warn that for rigidity it is necessary to provide reinforcement, although it can be done not only with sickle tape, but also with paper tape;
In my opinion, it is much better to use paper tape for the front, since it is much easier to plaster the surface with it. The fact is that it is thin and you can easily putty on it without noticing changes.
Plastering
If you are interested in the question of whether it is necessary to plaster drywall under wallpaper, then you are deeply mistaken - you have an excellent, flat surface, therefore, there is a base. If you apply putty, you will simply get extra work - the isogypsum will take your money, but at the same time you will not gain anything in a technological sense.
However, the answer to the question whether it is possible to plaster drywall with your own hands will be positive - yes, you can. And in some cases it is even necessary.
For example, if you want to paint a room, especially in light shades, then it is best to apply a layer of putty, as in the photo above. In this case, color differences will not be visible on the finished surface.
But again, the answer to the question of whether it is necessary to plaster gypsum board cannot be unambiguous - everything is done at your discretion and based on the specific situation.
If you decide to take action on how to plaster drywall, then the layer of plaster should be no more than 0.5-1.0 mm.
In this case, it does not matter at all where the spatula blade is directed - the main thing is that there are no grooves or depressions left.
What matters is the angle at which you hold the spatula to the surface - the larger (dumb) it is, the thicker the layer will be and, vice versa, accordingly.
You can also apply decorative plaster on drywall. You can take any putty and use it on flat surface. The fact is that gypsum board is already dry plaster of walls, all you have to do is add uniqueness to it, for example, cover it with “bark beetle”.
There are no differences in how to plaster a ceiling or a wall, but, as I mentioned, any work on the surface of the ceiling is somewhat more difficult, since you need to pull your hands up. In any case, the joints need to be sealed. You can use either sickle tape or paper tape here.
If the room is large, the plasterboard is hemmed in a checkerboard pattern, as in the top image. This avoids cracking at the joints. This method is especially relevant if you live near an airfield, railway or a busy highway.
But here the question of how to plaster a ceiling, or rather, how to do it correctly, again comes down to sealing the seams - you need to start with them:
- first you prime the seams;
- seal them with paper tape or sickle tape;
- let it dry;
- then cover the entire area with finishing putty.
The photo shows the result of correct actions
I would also like to say that ceilings are plastered in 99% of cases; as a rule, they are prepared for painting. Only as an exception are they covered with wallpaper or tiles, and the price in such a situation varies depending on the cost of the materials.
You can, of course, paint drywall, but you will need to apply 4-5 layers of paint, whereas with putty - only one or two.
I draw your attention to the fact that plaster is a leveling of the surface, and plasterboard already levels it, so putty is needed here only as a decoration. There is also no point in using starting powder mixtures - immediately work with the finishing mixture.
And one more important point- it is advisable to do all the work (I mean one plane - a wall or ceiling) at one time, so that there is no docking. This is especially important for decorative plasters - if they are combined, it will be noticeable even to the naked eye.
Conclusion
So, the answer to the question of whether decorative plaster (or regular plaster) can be applied to drywall will be positive. However, you should determine whether there is a need for this. There are no two opinions here either - there can only be an overconsumption of material and labor costs.
If you have specific questions on this topic, then ask them to us on the site forum or in the comments. Before that, watch the video in this article, here you will find visual information.
Sometimes during the renovation of a room whose walls are lined plasterboard sheets, the question arises - how to plaster drywall?
Despite its apparent simplicity, the question is far from idle, since drywall is often called “dry plaster”.
It is in the subtleties of the rather complex and ambiguous relationship between coating and plaster that we will try to understand this material.
So first, and main question— Is it possible to plaster drywall?
To date, there is no consensus on this issue, Unfortunately no. Many experts are inclined to believe that such surfaces (and even more so if the wall is made of a fairly cheap, non-moisture-resistant sheet) should not be plastered under any circumstances.
Sooner or later, under the influence of moisture from the composition and its considerable mass, the base will deform, which will lead to cracking of the layer.
However, there is an alternative opinion, which says that it is possible to plaster drywall. If you're careful, of course.
IN in this case“Caution” means, first of all:
- exclusively on a moisture-resistant sheet.
- Use of special deep penetration primers.
- Distributing the mass in thin layers in several stages.
The only exception regarding which experts are unanimous is. It is not only possible, but also necessary to apply it to a sheet; such a mass is one of the most popular materials for wall decoration.
Determining the need for plaster
As you probably already understood, plastering drywall is a rather difficult task with sometimes unpredictable results. These are the characteristics of the sheet; it can really become deformed under a thick layer of finishing. Or it may last for many years.
So, when should you plaster?
- If the wall cladding has significant curvatures or displacements, finishing will not solve this problem, and in the future may significantly aggravate it. If you become the “lucky” owner of such a wall, it is better not to fight the consequences, but to eliminate the cause. Serious distortions can only be corrected by reinstallation, replacing sheets with moisture-resistant ones.
- But minor unevenness in the sheathing can still be plastered. It also makes sense to apply the mixture over dents and pre-filled seams.
- Well, the only case (we have already mentioned it above) is the use decorative covering. There are practically no restrictions here, since the decorative mass is applied, as a rule, in a fairly thin layer, and its composition ensures rapid polymerization and drying.
And compliance with the application technology on the base does not lead to negative consequences.
So, let's assume you have already decided whether the drywall needs to be plastered, or whether you can get by with putty. It remains to choose the most suitable technology and the composition of the mixture. Let's get started.
Application technology
When applying, you must follow the work technology; the slightest violations can lead to undesirable consequences.
Preparing walls for final finishing
- We clean the surface from dust that inevitably forms during its installation. An industrial vacuum cleaner is best suited for this, but if you don’t have one, you can remove dust with improvised means.
- The next stage is filling of seams, joints and irregularities. For putty, both ready-made and dry putty mixtures can be used. If dry mixtures are used, prepare them immediately before work.
- First, fill the joint cavities and large uneven areas with putty. After the putty has hardened, apply a leveling layer.
- Now you can move on to the key stage of preparation - priming.
Primer
For bases, special primer mixtures are used (such as Tiefgrund LF or similar characteristics). Such primers penetrate deeply into the thickness of the base and strengthen it, ensuring adhesion to the mixtures.
For best effect on at this stage It is better to use acrylate primers, which have vapor-permeable properties (do not isolate water vapor).
Apply the primer in one layer using a roller or brush (for walls with a small area).
Note! Work on drywall is carried out only after the primer has completely dried! For acrylate primers, drying time is 1-2 hours.
After the seams are filled and the primer is applied, you can proceed to leveling the walls.
Applying plaster
Instructions for distributing plaster with your own hands:
The mass is applied in a thin layer (no thicker than 2-3 mm) using wide spatula or a metal smoother. If plaster is used to level out deep unevenness, the distribution is carried out in several stages. Remember that in this case it is better to apply 3-4 layers of several millimeters each than 1 thick layer at once.
Not any plaster is suitable for finishing plasterboard surfaces. It is best to use mixtures based on a gypsum binder (for example, Knauf Rotband).
In order for the finish to “stick” better, you can use fiberglass mesh with a 5 mm mesh.
After the plaster layer has completely dried, you can begin finishing the plasterboard walls. In this case, it is better to use vapor-permeable materials for finishing that do not prevent water vapor from escaping from under the finishing.
Decorative plasterboard plaster To finish plasterboard surfaces, it is better to use fine-grained decorative plaster. This is due to the fact that laying coarse-grained fractions requires applying a sufficiently thick layer, and in the case of plasterboard walls
this is undesirable.
The process follows the following scheme:
The plasterboard base must be dry and clean. Before starting work, the surface should be completely dust-free.
After the surface is dust-free, we proceed to filling the seams. We fill the seams with putty in several stages, providing sufficient time for the coating to dry and polymerize. As a result, seams and irregularities must be puttied in the same plane as the drywall.
Note! When leveling the surface of drywall for decorative plastering, you may not achieve as smooth a surface as when leveling for painting. The texture of the plaster hides all irregularities well. Apply an acrylate primer to the putty base. For decorative plastering, the same primers are used as for finishing ordinary drywall lime plaster
. The primer is applied in one step, in one layer.
Apply plaster to the primed drywall. We apply it using a spatula or trowel, in a layer of 2-3 mm.
Note! When applying decorative plaster to a plasterboard base during the formation of the relief, do not apply excessive force. This can cause the drywall to warp.
Further processing (painting, coating protective composition) can only be carried out after the surface has completely dried.
Summing up
Now you know how to properly plaster drywall. In order to more accurately understand the technological and practical issue, presented on our website detailed photo instructions, in which you will find necessary information on this issue. Good luck!
