Good plaster for apartment renovation: which one is better to choose. Which plaster is better for walls and ceilings Construction mixture for leveling walls

Previously, to level the walls or ceiling in an apartment, one single method was used - finishing the surfaces with cement mortar.

Today, there are various ways to solve such problems, one of which is the use of gypsum plaster, which allows easily and quickly correct various shortcomings working area.

What is this type of mixture?

Gypsum plaster is produced in the form of a dry (sometimes ready-made) mixture, the basis for which is natural gypsum, containing lime and perlite additives.

Ready mix looks like a pasty mass and is used to perform interior decoration premises.

To apply the solution, both manual and machine methods are used.

Which is better - cement or gypsum?

The question often arises: which plaster to choose? Let's try to figure this out.

Cement mixture is more common used for outdoor work. Its main component is lime, which acts as a plasticizer. It makes the solution more plastic and prevents cracks from appearing on the frozen surface.

Cement mixture, unlike gypsum, has increased stability resistant to moisture and low temperatures, and can be used for a longer time.

However, gypsum plaster superior to cement in environmental friendliness. When using a gypsum mortar, the finished surface has a smooth structure, while a cement coating requires finishing procedures.

Among main distinctive properties of both mixtures the following can be distinguished:

• cement plaster has a lower price;
• the main advantages of gypsum mortar are high adhesion and plasticity, this greatly facilitates plastering work;
• The main disadvantage of cement mortar is the need to apply a minimum layer with a thickness of 20 mm. In the case of a gypsum mixture, this figure is 5-10 mm, depending on the manufacturer.

Comparing gypsum and cement taking into account the nature of the finishing work, we can say that for external plastering it is more suitable option- This cement mortar, while for interior decoration it is better to choose a gypsum mixture.

Manufacturers

Today in the production of gypsum mixtures many manufacturers compete that offer various options products. Each type of mixture has its own specifications and properties. Below will be presented short review some types of plaster.

Knauf

Rotband plaster from Knauf is used for construction and interior repair work.

Well suited for finishing bathroom walls, as well as smooth wall surfaces and ceilings in residential areas. Can be applied to walls made of any material.

Mixture composition: gypsum powder with light filler and polymer additives that improve adhesion. Consumption per 1 m2 with a layer thickness of 10 mm – 8-8.5 kg. This type of mixture has a high rating among consumers.

Advantages:

• fire resistance;
• environmental friendliness;
• high-quality adhesion;
• vapor permeability.

The disadvantages include the need to use a special primer in cases where the plaster is applied in several layers, as well as the high cost of the mixture.

Volma

Some consider it a domestic analogue of Knauf, differing lower cost. It is used both for leveling surfaces during minor repairs and for performing capital works when finishing procedures are carried out from scratch.

Can also be applied when creating decorative elements, arches and reliefs. The consumption rate per 1m2 is 8 kg.

Advantages:

• using this mixture, you can level the walls with one layer up to 60 mm thick. However, experts recommend applying no more than 30-40 mm for more convenient plastering work;
• the soft solution is plastic and easy to apply;
• plaster is a pure white color (some mixtures may have a pinkish, light gray or beige tint).

The disadvantage of Volma is the use of gypsum from various deposits in its production, which in some cases negatively affects the quality of the plaster.

Ceresit

Depending on the type, it can be used for applying thin decorative layers on surfaces of various types.

Whether it be bases made of cement, concrete, plasterboard, chipboards and other materials, or for surface leveling both indoors and outdoors.

Consumption: 2.4 kg per 1 m2 with a layer thickness of 1 mm.

Advantages:

• impact resistance;
• vapor permeability;
• hydrophobicity;
• resistance to weathering and ultraviolet radiation;
• frost resistance.

Unis

Designed for leveling vertical and horizontal surfaces (ceilings, walls). Contains a special additive – perlite, due to which the setting time of the solution is reduced. The average consumption with a layer thickness of 5 mm is 4.5 kg per 1 m2.

Advantages:

• plastic;
• moisture resistance;
• ease of use;
• more a light weight, unlike other materials.

Flaws:

• the finished mixture is suitable for use for a short time (50 minutes);
• inferior in strength to drywall and cement mortar;
• the need to use a primer when carrying out plastering work.

Founds

Used for leveling walls and ceilings inside dry rooms.

This plaster can be used to treat any type of surface.

Consumption: 9 kg per 1 m2 with a layer thickness of 10 mm.

Advantages:

• ease of use, the plaster is easy to apply and level;
• high vapor permeability;
• After rubbing, the surface acquires a smooth structure and does not require the application of putty.

Prospectors

Facade plaster is used for applying on durable and reliable surfaces not exposed to moisture. Material consumption is 9.5 kg per 1 m2 with a layer thickness of 10 mm.

Advantages: in this regard, the performance of the “Starateli” mixture is almost the same as that of previous types. To these we can only add accessibility and reasonable cost of material, which are achieved due to the fact that this product is produced by a domestic manufacturer.

Why prime walls before plastering?

This question has several answers:

1. During the priming process, dust and grains of sand are removed from the surface. In addition, the primer fills small cracks.
2. The adhesion of the surface to the plaster solution improves.
3. The likelihood that the walls will become damp in the future is reduced.
4. Correctly selected and applied primer will increase the service life of the plaster coating.
5. When choosing a primer with antifungal properties, the treated surface will be protected from the formation of mold and bacteria.

Almost everyone who decides to carry out renovations in a house or apartment encounters the curvature of walls. A surface that has deviations within a few millimeters per meter is very rare. Much more often, existing shortcomings make you think about how to level the wall with plaster. Of course, this is not the only solution, but the most commonly used one, since even a person without much experience can perform it.

When it comes directly to working with surfaces, a difficult situation immediately arises, because construction market There are many types of material for these purposes. And the question of which plaster to choose for leveling walls becomes a real problem for many.

There are two main options to focus on.

Cement based plaster

This mixture is considered universal. It must be taken into account that there are two varieties that differ in the fraction they contain. To create the main (rough) coating, a material with inclusions of coarse sand is used. Finishing is done using products with the addition of very fine sand. In any case, finishing lining with putty will be required, especially if paint will act as a decorative layer.

Cement based plaster

The cement mixture has the following advantages:

1. Low cost, which often determines its popularity.
2. Durability. If you follow the application technology, the service life is calculated in decades.
3. Quick preparation of the solution and ease of application. The setting is not too fast, which is ideal for beginners.

Advice! To make the mixture more plastic, acquire better fixation and antibacterial properties, add a little lime to it. It should be taken into account that this component previously acted as independent species plaster, but currently it no longer meets the requirements.

Cement plaster is low cost and highly durable, which makes it a very popular material for leveling walls.

There are also significant disadvantages:

• The applied layer cannot be thicker than 1.5–2.5 cm, otherwise there is a high probability of cracking. Therefore, if the situation requires it, it is advisable to split the process into stages, additionally using a reinforcing mesh.
• The long setting of the solution is not only a positive aspect, but also causes some problems, because the entire process requires much more time.

All this affects the fact that the work turns out to be more tiring. But in some cases, cement mortar may be the only solution.

This option is very popular for because it has many positive characteristics:

1. Safety. The material is completely safe for humans and pets, which makes it indispensable when used in a children's room.
2. Excellent moisture absorption. This indicator affects the microclimate of the room. It is the gypsum mixture that has unique property– absorb excess moisture from the air and, if necessary, release it back.
3. Economical. The solution consumption is significantly lower than the previous version, which allows you to treat a larger area with the same ratio of materials.

A significant disadvantage is the rapid setting. Therefore, the work must be carried out quickly, which requires the presence of certain skills. You cannot prepare more mixture than is necessary for a certain area, because the excess completely loses its properties. Many consider the disadvantages to be higher cost than that of a cement product. But you need to take into account that the consumption of this material is less, this evens out the difference.

So which plaster is better? This question does not have a clear answer; one must proceed from specific situation, based on the parameters and characteristics of the room.

Ways to level walls

There are two main ways to level walls using plaster. But no matter which one you use, it all starts with preparation:

• The surface is cleared of all protruding elements. If the base is brick wall, then it is advisable to unstitch the existing seams.
• Dust and dirt are thoroughly removed.
• Impregnation is carried out with a primer composition that increases adhesion. The solution is selected depending on the base and the selected material. There must be at least two layers applied.
• Antifungal agents should be taken care of. In most cases, they are included in the primer, but it is better to pre-treat with highly targeted preparations.

It is necessary to take care in advance of choosing all the required tools.

Beacon method

Leveling walls with plaster according to beacons is good decision, if there are significant deficiencies and the area of ​​work is quite large. Difficulties can only arise during the installation of the guides.

The beacons are being attached different methods, but the most commonly used is installation on plaster or cement.

The technology is as follows:

1. Markings are made on the surface. Lines are drawn from ceiling to floor in strictly vertical accordance. The step between them is no more than 100 cm. In general, it is more convenient to focus on the length of the rule.
2. Special slats are purchased. It is important to make sure that they are level.
3. Screws are screwed in along the edges, top and bottom, and a cord is pulled between them.
4. The two outer profiles are attached first. To do this, a small amount of solution is dotted onto the lines. The rail is pressed a little and checked for level, after final alignment it is secured.
5. The remaining slats are beaten along the cord.

After the guides are fixed well enough, the main alignment stage begins:

On a note! To get even corners and avoid long-term work with them, you must follow simple rule: Allow a little time for the first wall to dry. This will eliminate the occurrence of distortions.

Follow-up when leveling

Leveling is not considered complete until the surface is completely ready. Therefore, the following final procedures are required:

• Grouting allows you to correct minor imperfections that could arise from the rule or after removing the beacons. To get a truly smooth surface, work must be completed within 12 hours after the plaster has set.
• For work, use a trowel or spatula, which is moistened in water. Movements on the grouting surface should be fast and multidirectional.
• The final stage, which takes place a couple of hours after the first, can be performed using a sponge. It is moistened in water and squeezed out. The walls are rubbed well, but without excessive pressure. Strong wetting of the coating must be completely avoided.

If everything is done correctly, the result will be a smooth plastered surface.

Beaconless method

If the walls do not have significant deviations, then a simpler option can be used for alignment. It must be borne in mind that it is almost impossible to obtain perfect evenness using this method. Therefore, it is more suitable for subsequent wallpapering or the use of decorative elements.

1. An even profile, strip or rule is applied to the wall, and any imperfections are noted along the entire perimeter.
2. Large protrusions are cleaned off or knocked down. When performing this process, you need to constantly apply a level so that instead of a mound you don’t get a hole.
3. The solution is poured into the recesses and immediately leveled.
4. After treating the area, apply the rule over the surface. If necessary, add a little solution to remove significant differences.
5. Finish the remaining wall area.

On a note! There is a dry type of plaster - gypsum boards. With their help, it is possible to achieve the desired result much faster. But the disadvantage of this option is the reduction in room area.

Plastering using the beaconless method is quite labor-intensive work, and it is not possible to cover large areas and completely eliminate defects. This method is most suitable for small surfaces where installing beacons simply does not make sense.

The following video will help you study in detail the process of leveling walls with plaster without using beacons.

Finishing work requires mandatory preparation of the base surface. Repairing cracks, holes, strengthening collapsing areas is always present work during renovations in an apartment, house, or any building. It is also necessary to level the walls for most types of decorative coatings. The main and most common way to achieve these goals remains plastering. This option has a number of advantages, one of which is strengthening the entire structure. There are several types of plaster used for walls. Each of them has its own characteristics and is used according to operating conditions.

Types of plaster compositions for walls

Construction mixtures intended for leveling walls consist of a binder base and additives that increase their functionality. The following is used as a binding material:

• cement;
• gin;
• lime;
• gypsum.

Gypsum plasters and cement-sand mixtures (CSM) are used most often. They are characterized by good plasticity and accompanying useful properties, which allows the formation of smooth surfaces during finishing.

If lime is added to a cement-based mixture, the plasticity of the solution improves. It becomes more convenient to work with him. Such compositions are called cement-lime.

In construction stores there are ready-made products packaged in special bags that help preserve the mixtures. Materials are allocated for initial (starting) finishing and finishing, for internal and facade works. They differ in particle size, constituent substances, resistance to external influences, price. The materials sold are intended for manual or machine application.

You can prepare cement-sand and gypsum plaster yourself. This, despite the increasing time costs, can save significant money. Most often, they make their own cement mortars because it is cheaper.

Plaster and putty are different materials. The differences are as follows:

• when plastering, the surface turns out to be rougher than after putty;
• in the first case, it is allowed to apply a layer up to 80 mm thick, in the second - not exceeding 5 mm;
• plaster is a material for initial finishing, and putty is for finishing.

Plastering refers to the “wet” version of leveling work. Before applying the solution, the base is always prepared.

Once the base coat has been created, the room can be decorated using decorative varieties plaster. The choice in this direction is very extensive. Mixtures are divided into the following types:

• structural;
• textured;
• Venetian.

By composition material is used in mainly based on the following components:

• acrylic;
• silicone resin;
• special glass.

Decorative materials are distinguished by their high price and excellent decorative properties. They protect the lower layers well. They are used for interior and exterior work.

Which plaster to choose for leveling walls directly depends on the conditions in which it will be used: outside the building or inside. This is due to the properties of the materials included in the composition: moisture resistance, strength, and the ability to withstand temperature changes without changes.

Comparative characteristics of cement-sand and gypsum mixtures

You should choose which plaster is better, gypsum or cement, based on the characteristics of the materials. This is due to the fact that each room has its own microclimatic conditions: humidity, traffic, temperature fluctuations and others.

A comparison of DSP and gypsum mixture is presented in the table below.

Characteristic	Gypsum composition	Cement-sand mixture
permeability to water vapor, mg/mchPa	from 0.11 to 0.14	0,09
average consumption per area of ​​1 sq.m. with a coating thickness of 1 cm, kg	from 7 to 10	from 12 to 20
moisture resistance (hygroscopicity)	humidity should not be more than 60%	moisture-resistant material
average setting period	about 50 min	2 hours

In wet rooms (bathrooms, kitchens), moisture-resistant gypsum-based mixtures or even ordinary ones are used. The last finished surface is treated with a waterproofing solution and a protective decorative coating is applied on top. It is easier to plaster ceilings with gypsum compounds.

If we look at it from an economic point of view, we get the following:

• cement-sand mixture is cheaper (by about a third);
• consumption gypsum materials may be on average 2 times smaller;
• Practically it turns out to be approximately the same amount.

It turns out that from the financial side it is impossible to say which best plaster is for walls.

The positive thing is that the gypsum coating dries faster and the next layer can be applied. But at the same time, one should take into account the short setting time of the mixed solution. After hardening, it is not recommended to dilute it with water, because the material will not acquire the required strength.

The cement mortar can be mixed for 2 hours. During this time it retains its plasticity. But you have to wait many times longer for the created coating to dry.

When carrying out external work and finishing wet rooms, it is recommended to give preference to cement-sand compositions. In dry rooms, it is more convenient to use gypsum mixtures, because they have better contact with the surface of the base, allow you to apply thinner layers, and with high-quality plaster and grout, you don’t even need to putty.

Options for preparing solutions at home

Ranok offers a lot to choose from ready-made options compositions. But when funds for repairs are limited, you have to look for another way out.

Mixtures for leveling walls can be prepared independently without much difficulty. This will be the most a budget option. But the time required to prepare the solution will increase. It is also necessary to take into account that various additives are added to the composition of factory plasters, depending on the purpose of the material: antibacterial, antifungal, improving frost resistance, plasticizers and others. This improves their performance.

You can also add additives to the solution you prepare yourself, but you will need to purchase them additionally.

Options for the proportions of plastering compositions, taking into account common application techniques, are presented in the table below.

The process of preparing the material in order to level the walls is as follows:

• dry ingredients are mixed in the specified proportions;
• then add water and stir the solution, bringing it to the desired consistency;
• then add various additives as needed and mix.

The work can be done manually with a shovel (and for small volumes with a trowel) or using a mixer. Even faster and easier is to use a concrete mixer. But the volume of the batch must be such that it can be worked out before it hardens.

In the manufacture of cement paste, the proportion of sand depends on the grade of cement: the higher it is, the more it can be added. Also, the proportions depend on the purpose of the solution: outside it is recommended to use a more durable option.

When preparing, you need to ensure that the sand used is clean. It is better not to use expired cement.

When prepared independently, you get cheap gypsum plaster or cement plaster, depending on the purpose of the solution. As practice shows, savings can reach 30%. Which plaster to use, ready-made or self-prepared, depends mainly on the price factor and the available time.

Popular ready-made formulations

The choice of plaster, in addition to determining the composition, is complicated by even more brands. Products with almost identical components have different prices.

The performance characteristics of the material depend on its purpose. A product that is similar in terms of this indicator is also similar in properties.

• Knauf;
• Volma;
• Ceresit;
• Unis;
• Founds;
• Prospectors.

The brands considered are gypsum and cement plaster; it is impossible to say which is better. But, if we take into account the degree of popularity among consumers, the Rotband plaster from Knauf stands out. With approximately the same characteristics, domestic products are cheaper than foreign ones.

Application methods

Today, when carrying out repair work, two plastering methods are used: manual and machine.

Wall leveling technology plaster solutions on different basis manually identical. The work is carried out according to the following scheme:

• prepare the work surface: remove old or defective finishes, clean from contaminants;
• prime;
• if differences exceed 3 cm, beacons are placed;
• apply the working mixture;
• the next level is thrown onto the previous one;
• The steps are repeated until the walls are level.

The use of plastering machines significantly increases productivity. The process goes like this:

• connect the mechanism to the power supply network, water supply;
• pour the dry mixture into a special compartment;
• everything is mixed inside the mixing chamber;
• the solution is supplied through a hose under pressure;
• The plasterer applies it to the surface of the base.

The machine monitors the quality of the composition. The worker adds material and applies it.

For manual plastering important point is compliance with work technology. Before choosing plaster, you should definitely take into account the method of application it is intended for.

An overview of plaster mixtures from different manufacturers is shown in the following video.

Ready-made materials for leveling walls based on gypsum and cement allow you to repair all defects and prepare surfaces for decorative design. The correct choice of mixture and adherence to plastering technology is a guarantee of obtaining good result, extending the service life of the building. High-quality repairs require financial investments. Helps you save self-cooking working solution, doing all the work yourself. But such an inexpensive option requires certain construction skills and knowledge.

Have you decided to renovate and don’t know where to start? More precisely, you know, but you’re afraid to admit it to yourself, because you look at your walls with a shudder. Yes, their curvature in most of our apartments is simply amazing. Therefore, the question of choosing a plaster mixture is relevant for everyone who has decided to do the repairs themselves.

There are not so many options for plasters, and we are all familiar with them:

• Cement;
• Plasters based on gypsum;
• Clay compositions.

On a note.

Primers and putties are also used to level walls, so their choice rests entirely with you. The primer is used for the initial treatment of the prepared base. For gypsum compositions, finishing putty is not required.

The surface treated with cement plaster must be puttied.

Construction plaster mixtures used to level walls can be either cement or gypsum.

We will omit clay, which is so popular for lovers of environmental cleanliness, since hardly anyone will buy such a miracle in a store. In any case, the choice depends on the room in which we are going to level the walls.

We will try to consider in detail all types of plasters, identifying the positive and negative properties each.

For the right choice it is very important.

Cement mixtures

In addition to sand of fine and coarse fractions and cement of various brands, cement plasters may contain lime. It gives the finished solution certain properties, which we will discuss below.

Construction mixtures used for leveling brick, concrete and other walls, in addition to the main components, include special polymer additives. This is related to the accuracy of preparing the solution:

• The mixture is poured into water (but not vice versa);
• Stir thoroughly with a construction mixer;
• Allow to stand for three to five minutes for the polymer additives to take effect;
• Mix again.

In the future, adding water or a dry mixture is not allowed, as its structure changes and adhesion deteriorates.

However, seasoned construction workers have learned to do this without harm to the final result.

Dry mixes are a box of surprises in their own way. Using them for leveling, you can save a lot of money (if you know all the nuances). For us, who do construction once or twice in our lives, compliance with the recommendations indicated on the packaging by the manufacturer is necessary.

On a note.

The quality of plaster depends not only on the size of sand granules or the addition of polymers. The brand of cement also plays a big role. The higher the M number indicated on the packaging, the stronger the final coating will be.

It is not advisable to choose super durable grades for leveling, for example, with M400 or M500, since they are more expensive, and the strength of the plaster on the walls of the house is not so high loads to use such strong cement.

This plaster mixture usually includes M150 grade material. This strength is sufficient for most residential buildings.

This type of plasters can be divided into two groups - cement-sand and cement-lime. The former contains cement with sand and polymer additives, while the latter, in addition to these components, also contains lime.

Cement-sand mixtures, properties

You can either choose this plaster in a store (ready-made dry mixture) or make it yourself.

It is clear that we will not be able to add any polymers there to improve its plasticity, but how Alternative option, it is possible to use a small amount of dishwashing detergent. Cement-based mixtures used to level walls are universal and can be used in wet areas.

Your choice (what it is intended for) depends on the size of the sand.

Solutions with large grains are suitable for rough work, since it is impossible to rub them perfectly, without streaks and holes. Plasters with finer fractions are suitable for fine finishing, as they rub well and the surface is smooth.

The advantages of cement-sand plasters include:

• Low cost;
• Durability of the finished solution;
• Ability to choose proportions and cook yourself;
• Applying a cement-based mixture for leveling walls does not require special knowledge.

Minuses:

• Cement-based plaster mixtures may crack after drying, especially if the layer was applied too thickly;
• The labor intensity of the process and its physical complexity;
• Poor adhesion to concrete walls (it is recommended to use special primers containing quartz sand);
• Drying time for each layer.

On a note.

When selecting components for making your own cement plaster, pay attention to the quality of the sand. It should not contain impurities (≤5% clay or silt is allowed). Choose grain sizes of 2/2.5 mm (for rough plaster) and 1.5/2 mm (for finishing plaster). A fraction of less than 1.5 mm will lead to cracking of the dried surface.

Therefore, a ready-made plaster mixture is preferable, since there is no need to independently control most of the parameters.

Dry ones are stored better and are not afraid of frost, but the packaging should be protected from moisture.

Cement-lime mixtures, properties

Lime is added to cement plaster to increase its plasticity. Such compositions behave like gypsum, but the life of the finished solution is longer, and the base itself can remain suitable for rubbing for a long time. Choose them if you want to get a high-quality surface and save a lot of money.

Pros:

• Protection against fungi and mold (antifungal properties of lime)
• Plasticity, while the mixture does not flake and does not fall off from the base;
• Cement-lime plaster has high “stickiness”.

  It can be used to work on concrete and even wood (shingles);

• The base, leveled with this composition, regulates the humidity in the room.

This choice is also due to the fact that it is convenient to work with walls covered with building cement-lime mixtures, because they do not fall off in layers, do not crumble, and drill well.

Minuses:

• Low compressive strength;
• The cost is higher than that of conventional cement-sand mixtures.

Pros and cons of gypsum mixtures

An excellent alternative to plasterboard and cement-lime plasters are gypsum mixtures, which are excellent for leveling dry walls, for example, in residential areas (living room, dining room, bedroom).

They have several cons– high cost compared to cement-lime and, especially, cement-sand ones, they are afraid of water, since gypsum has high water absorption, they harden quickly.

Therefore, immediately knead large volume Gypsum plaster is not allowed.

TO pros Let's consider plasticity and ease of use. You can begin leveling almost immediately after application; such mixtures have good sound insulation and heat insulation qualities.

The layer dries quite quickly.

When choosing plaster, remember that it requires some skill. A dried solution is not suitable for use. They throw him away.

The choice of gypsum mixtures is also advisable because it is possible to simultaneously apply a layer up to 6 centimeters thick.

They can be used to level walls that are piled up at the top. In addition, one layer is often enough to make the surface perfectly flat and smooth.

Brands producing various plasters

Foreign and domestic companies have long mastered the production of various plaster mixtures. Here are just a few of them.

Foreign companies producing dry plasters:

• Knauf;
• Concrete;
• Ilmax (Belarus);
• Plitonite (Russian-German).

Domestic companies:

• Ceresite;
• Bolars;
• Eunice;
• Litokol;
• Besto;
• Ivsil;
• Volma;
• Found.

As you can see, the choice is huge.

Each brand produces both gypsum and cement plasters. In addition to dry mixtures, the product line also includes other materials necessary for work - primers, putties.

Russian brands are represented in the majority, but the quality of their leveling mixtures is no worse than that of foreign ones.

Which plaster is better for walls and ceilings

Therefore, the choice is yours.

Before going to the store, carefully calculate the expected consumption of material for leveling the walls and buy it with a small margin.

Decide on the type of plaster (dry or ready-to-use, gypsum or cement). Also, do not forget to purchase primers and putties from the company you have chosen, because they are adapted to each other. Using products from different manufacturers may not give the results you expect.

Overview of wall leveling mixtures

The presence of an uneven wall shows that urgent measures need to be taken to solve this problem.

A room looks ugly if the walls are uneven or curved. We'll give you some useful tips about how to sort walls yourself without touching strangers, and talk about ways to level walls.

So let's think about ways to level the walls.

The first method is to level the multi-layer if the wall is curved. Some layers of plaster applied to the wall must be filled in the right places. This procedure is repeated several times until significant improvement occurs. The following method is compensated by drywall. This method is the simplest and most convenient, sheets of drywall are glued to the wall as you coordinate yourself to make the desired thickness and cavities in the wall to complete the alignment.

Another way is to reconcile the so-called beacons.

This method is suitable for those who have too curved walls and that other methods do not help; only with the help of beacons can a positive result be achieved.

After applying the beacons, you should use a mixture of plaster, and then use a second layer of whale. Let it dry and wake up again to plaster the wall, the result will be obvious.

What mixtures can you choose to level the walls?

Today there are many mixtures for smoothing walls.

Manufacturers and various companies offer their products, so it is important to choose not only a high-quality product, but also an affordable one. Together we will understand which mixture is better to choose. To level the walls, use dry mixtures, which are then divided into rows. There are some types of dry mixes: base color and putty, patches for interior and exterior use, stainless flooring, adhesives and special purposes like fire retardant.

All these types of mixtures must be carefully selected, specifically adapted to the problem of uneven walls and strictly follow the instructions for use.

Each company that produces its products is unique.

At the market you can find the most famous brands that perform dry cleaning. For example, KNAUF is a well-known German company, Vetonit is a French company and many Russian manufacturers, such as Bolars and Volma, as well as many others. Each of these companies will help you achieve certain results, if you do everything right and follow all the steps, then you will have to manage them yourself.

We'll look at the three main types needed for a level wall.

These include example, whales and gypsum. The coating is necessary to secure the material to the wall, improve adhesion, and keep the material dense and more stable. The plaster is needed directly for leveling, without even measuring it. Therefore, it is important to know which mixture to choose, and on which wall - brick or concrete.

And finally, the kit is used to eliminate small errors and roughness on the wall.

Tools and materials necessary for working with wall leveling.

All parts require certain tools and materials.

We will look at what tools are important for leveling the walls of a house. To match the wall kit, the following tools are needed: plaster and base, small and large trowel, especially at the angle of the trowel, Rende needed for sanding, for undercoat, necessary cushions, for mixing necessary utensils

If you are leveling beacon walls, you will need tools such as a screwdriver, punch, putty knife, striped line, dowels.

Here are the basic tools you'll need to help you straighten and straighten your walls effectively!

How to straighten the walls yourself.

Which plaster is better

(Instructions for photos and videos).

Let's say you need to build walls in brick house, the procedure itself begins, especially by laying down the powder. Spray some water on the wall to create surface moisture and use gypsum mortars. It should be noted that the plaster is applied in three layers to the wall. We will discuss them in more detail. There are layers such as mites, soil and covers. The spray is a thinner solution applied to the exposed wall and the entire process is suddenly completed to fill all the cracks.

The next layer is soil, which is the densest of the three layers and is applied to the wall in several stages.

The last layer will be the cover, which is one of the smallest deposits on the wall, as it is made of fine sand.

It should be used in a circular bend across the entire wall so you have a completely flat surface.

It is very important to remember that when applying any layer of powder or plaster to a wall, each of them may dry out, it will largely depend on the material and thickness of the coating. We believe that the walls you have will not only be the same, but they will also have their own uniqueness and your work will bring long-awaited results.

Leveling walls by hand

The need to eliminate defects and unevenness on the walls is beyond doubt. High-quality preparation of premises for finishing with wallpaper is an obligatory stage in construction. The choice of materials and technology for carrying out work depends on the degree of curvature of the walls and wear of the old layer of plaster, the depth of the cracks, deviation from the vertical, as well as the amount Money allocated for leveling the walls for wallpaper, repair time.

Methods for eliminating defects and uneven walls

In accordance with the requirements of SNiP, the vertical and horizontal deviation when plastering indoor enclosing structures should not exceed 3 mm per 1 m² of their area.

The technology for leveling walls under wallpaper is based on the use of gypsum board sheets and liquid mixtures. These include plaster or putty. A wide range of materials for performing this procedure provides the opportunity to choose best option and qualitatively prepare wall surfaces for wallpapering.

In the absence of experience and skill, it is not recommended to carry out finishing work yourself.

It is better to seek the help of professional craftsmen who have experience and practical skills in eliminating defects and irregularities, ordering their services at competitive prices.

Leveling with putty

If minor defects are detected and the difference between the diagonals of the walls does not exceed 10 mm, it is recommended to use putty to level the walls.

The materials are sold in the form of ready-to-use solutions or dry formulations that must be diluted with water in accordance with the manufacturer's instructions. The putty consumption rate is 1 kg per 1 m² of surface to be leveled.

The technological process of high-quality preparation of walls before finishing them with wallpaper and eliminating minor cosmetic defects using dry or liquid mixtures involves performing certain stages.

These include:

• cleaning wall surfaces from dust, cobwebs and their subsequent treatment with antibacterial agents;
• wall primer;
• applying a layer of starting putty, the thickness of which is determined by the angle of inclination of the spatula to the wall;
• laying the painting mesh on the first layer of leveling material;
• applying a second layer of putty in the direction perpendicular to the starting layer of finishing material;
• washing out the finishing layer of the liquid mixture intended to level the surfaces of vertical enclosing structures indoors with a primer composition;
• sanding walls using sandpaper, a special mesh for removing roughness after the putty mixture has dried.

At each stage, after applying a layer of putty, it is necessary to give time to remove moisture from the solution.

The material dries within 24 hours. Quality control of work after each stage, carried out in accordance with the technology of wall putty, eliminates the need for rework. The surfaces will be smooth and ready for wallpapering.

Leveling with plaster

Knowing how to level walls for wallpaper using plaster, you can get perfectly smooth surfaces in the presence of recesses with a depth of 2 cm, and horizontal and vertical deviations of up to 15 cm.

The finishing material is presented in various types and can be based on a lime mixture, cement-sand or gypsum mortar.

The technology of leveling wall surfaces using plaster is considered the most complex and labor-intensive process for eliminating deep flaws, requiring certain skills and professionalism. The material is distinguished by its versatility, functionality, resistance to moisture, pathogenic microflora, ease of maintenance, and the ability to give walls perfectly smooth contours.

At all stages of leveling surfaces with plaster before gluing wallpaper, it is recommended to be careful and avoid haste. Each layer of finishing material applied to the wall must dry completely.

How to level the walls? Materials for leveling walls

Otherwise, excess moisture will lead to damage to the wallpaper, and gluing it will turn into a complex, time-consuming process.

The procedure for leveling surfaces with plaster is to carry out a number of activities. These include:

• identifying the depth of defects and unevenness of wall surfaces;
• thorough cleaning of vertical enclosing structures from dust, old decorative coatings, dirt;
• treatment with a primer solution;
• consolidation plaster mesh with cells 5x5 cm, necessary to prevent cracking of the leveling coating;
• installation of beacons along the edges of walls using a building level and over the entire surface area in increments of 20 cm, determining their location using a cord;
• wetting vertical enclosing structures that need to be leveled with finishing material before decorating with wallpaper;
• applying a layer of liquid coarse-grained mixture, 3-5 mm thick;
• waiting for the plaster to dry completely;
• applying a base layer of leveling mixtures to eliminate deep flaws and uneven walls, 5-7 mm thick;
• waiting for the solution to set until it dries completely;
• creating a finishing layer of plaster with a thickness of 2mm to 4mm;
• leveling the surface of plastered walls with metal floats so that the leveled surfaces are perfectly flat and smooth;
• primer treatment for the highest quality preparation of walls for wallpapering.

Before all stages of layer-by-layer application of coarse-grained finishing material to eliminate deep defects on the walls, quality control of the work performed is carried out.

For these purposes, a building level is used. Wallpapering walls is allowed 1-2 weeks after the leveling mixtures have completely dried.

Alignment with gypsum board sheets

Application plasterboard sheets to eliminate defects and severe unevenness of walls before decorating with wallpaper, it provides the opportunity to solve problems of any level of complexity. The material is environmentally friendly, easy to install and can minimize labor and time costs before finishing the premises.

With the help of gypsum plasterboard sheets, uneven walls are perfectly leveled. And decorating them with wallpaper will provide an opportunity to provide unusual design and create original interior in room.

The technology for installing gypsum plasterboard sheets is determined by the level of curvature of the walls.

If their values ​​exceed 7 cm, it is recommended to install a frame from a metal profiled corner or wooden blocks and attach drywall to it with self-tapping screws in increments of at least 30 cm. If a lower level of wall curvature is detected, gypsum board sheets can be glued to the walls using special solutions that ensure high-quality fixation to their surfaces.

The stages of leveling walls with gypsum board sheets include:

• determination of drywall fastening technology;
• marking the location of sockets, switches and plasterboard sheets on the leveling surface;
• installation of drywall to the walls;
• puttying of the joints between gypsum board sheets and fastening elements, in the case of using self-tapping screws for attaching them to the frame.

When leveling the surface with plasterboard, it is necessary to adjust the position of the sheets according to the building level.

Such methods of eliminating unevenness and defects of wall surfaces before wallpapering them provide an opportunity to choose the best option and create a unique interior style.

Properly aligned walls are the key quality repairs!

Leveling walls with wet mixtures

Despite the ease and convenience of leveling walls with materials made from sheet metal, the most common balancing method with wet mixtures.

Wet mixtures are plaster and whales, which you can buy in ready-made stores.

For this you don't need high level scraps, and you can buy wall smoothing compound at any building store.

The essence of the task is to clean the wall of old finished materials, measure the unevenness (this can be done using a construction level or stretching any rope along the wall) and level them in layers.

Hard and dirty

Not all apartments can boast of smooth walls. And if this may not be noticeable when wallpapering, then when installing ceiling plinth, all the shortcomings immediately emerge. Most often this can be found in houses built in the 50s and 60s. Depending on the degree of curvature, there are several ways to level the walls with your own hands. They will be discussed in the article.

Leveling walls with plasterboard

This is the most acceptable option for leveling walls and ceilings with your own hands. Fastening sheets of drywall does not require special skills, and the work is done quite quickly. There are 2 ways to do this. If the curvature of the walls does not exceed a level difference of 4 cm per 2 linear meters, then a faster one will do. frameless method. If it is necessary to hide communications or additionally insulate the walls during leveling, install a frame.



Before starting work, you need to select the right material:

• for a living room with normal humidity, ordinary drywall with a gray front side is suitable;
• for a bathroom or any other room with high humidity, to level the walls, choose a special moisture-resistant gypsum board with a green front side. It has special impregnations, but costs a little more than usual;
• for rooms that have high fire-resistant requirements, for example a kitchen, it is recommended to choose GKLVO. These sheets are moisture and fire resistant, green in color with red markings.

Technology for leveling walls with plasterboard without a frame

When the walls are almost flat and have minor differences, the stages of work will look like this:

• thorough preparation of the base, including complete removal of wallpaper or paint to the plaster layer;
• Next, it is recommended to tap the entire wall; if voids are found or the plaster is coming off in some places, it must be cleaned and a layer of putty applied to level it;
• at the end, remove all dust from the walls using a broom or vacuum cleaner. If this is not done, the layer of dust will reduce the adhesion of the adhesive to the base;
• Now the surface can be primed. Since gypsum board sheets are heavy, it is better to use special primers for concrete that contain sand. This will increase the reliability of fastening to glue;



• Drywall adhesive is always sold dry. Before work, dilute the required amount (it is better to prepare a little for the first time) of glue. The consistency should be similar to an adhesive composition for tiles, that is, to be quite thick. For kneading, use a screwdriver or drill with a mixer attachment. Before starting work, it must sit for 5 minutes;
• The method of applying the glue will depend on what facing material in the future it is planned to apply it to the aligned plasterboard wall. If it is wallpaper, then glue is applied around the perimeter and in the center in small portions. But for finishing with heavy tiles or stone, the adhesive composition is distributed evenly with a notched spatula over the entire surface of the sheet, also having previously applied it to the wall itself;
• The gypsum board sheet is applied to the wall, leveled and pressed tightly by gently tapping it with a rubber hammer or fist. Do not forget that this is a fragile material and can easily crack.



• If there is a socket at the attachment point, then before attaching the sheet, its location is marked on it. You can cut it after fixing it directly in place;

Tip: cutting drywall evenly and accurately is quite difficult, so there are often miscalculations. It is best to immediately putty such places using serpyanka. If the hole is made in the wrong place, then it must be sealed with alabaster.

• Having attached the first sheet in the corner of the room, the second one is mounted closely to it. They should be located on the same level. If, when pressed, the glue comes out beyond the sheet, it must be immediately carefully cleaned off with a spatula. There should not be even small gaps between the sheets.

Leveling walls with plasterboard with very strong unevenness

In some cases, the walls have significant differences in height, but it is not possible to make a sheathing frame. For example, if the room is very small. If you don’t want to work with putty, you can also turn to gypsum board sheets. In this case, the order of work will be as follows:

• in fact, it will not be possible to do without a frame entirely, but instead of slats or a profile whose thickness is at least 3-4 cm, plasterboard will be used. To do this, a sheet 9 mm thick is cut into strips 10-12 cm wide;



• they are glued vertically in increments of 40 cm. It is advisable to use glue with the greatest fixation; apply it in a thick layer. In the future, it will be he who will take on the maximum load. The composition is given time to fully set - 2-3 days;
• Then the sheets themselves are glued to the finished frame. IN in this case better to refuse wall option 12.5 mm thick and choose thinner and lighter 9 mm thick plasterboard, originally intended for the ceiling.

Advice: despite its apparent ease, leveling walls with plasterboard without a frame is quite labor-intensive and difficult. You not only need to choose the right adhesive composition, but also carefully seal all resulting joints with putty.



Aligning walls with plasterboard with frame

• When arranging the frame, preliminary preparation of the walls is reduced to a minimum. But it is still advisable to remove all loose coating, be it peeling wallpaper or crumbling plaster. If possible, walls are treated with antiseptic primers.
• Both inexpensive wooden slats and special ones are suitable for lathing. metal profiles. The latter are recommended for use in rooms with high humidity. If wall leveling work is carried out in wooden house, then the frame is attached using self-tapping screws; in an apartment with brick or concrete walls you will need a hammer drill and dowels.
• The first profile rail is mounted in the corner vertically along the entire height of the wall. All subsequent ones are arranged similarly in increments of 60 cm. This distance is due to the standard width of the plasterboard sheet of 120 cm.



• On all other walls, slats are attached in the same way. Be sure to make a sheathing around each window and doorway in the form of a border. When it is finished on all the walls to be leveled, they begin to attach the sheets.
• First, place whole sheets, starting from the bottom. The standard height is 250 cm, for most city apartments this is enough to create a seamless coating. When the ceiling height is higher, a patch of plasterboard cut to exact size is made on top.

Tip: GKL sheets around the perimeter have beveled edges, making them easier to putty. Therefore, when connecting small pieces of materials, you must try to ensure that these edges are at the joints.

• For fixation, black 35 mm self-tapping screws are used in 15 cm increments along all slats, which are located under the sheet. They should fit into the material in such a way that the caps do not stick out, but do not go deep either, but are exactly flush with the surface. When the sheet is completely screwed, you need to check all the screws; it happens that some of them begin to stick out. In this case, they should be tightened.



Tip: they are sold to cut drywall special devices, but for small scales a regular stationery knife will do. First, firmly apply a guide (for example, a rail, a level) and make an even cut along it stationery knife, deepening it into the material as much as possible. We must try to cut through all the plaster, for this you need 2-3 passes with a knife. Then the sheet is lightly pressed in this place and the back side of the cardboard is cut through. As a result of such work, a lot of gypsum dust is generated.

• Attaching all the drywall is only the first step in leveling the walls with your own hands. Then they are primed and first only the joints and places where the screws are screwed are puttied. For greater strength and to prevent subsequent cracking at the joints of individual sheets of drywall, they are glued with sickle tape. It goes deep into the putty composition so that it does not protrude beyond its limits. Having finished the work, the composition is left to dry for a day.



• Next, apply a finishing layer of plaster or putty over the entire surface of the wall. This hard work, in the process of which, it is necessary to make an absolutely flat surface of the entire wall area. No sagging or depressions should be allowed. Even further sanding special grater will not allow you to completely hide them, and they will certainly appear not only through painting, but even through textured wallpaper.

Leveling walls with putty

• Another traditional way of leveling walls is with or without putty. It is used in the construction of new brick houses or when renovating apartments.
• To do the job efficiently, you need to choose the right putty composition. They differ in composition depending on the intended operating conditions. There are two main types: gypsum and cement putty. Let's look at how to work with each of these compounds.

Leveling the surface of the walls with gypsum putty

• This is an excellent composition if you need to level walls small area. This is due to the fact that the composition hardens and sets quite quickly. For this reason, it is also recommended for repairing and sealing small cracks or chips that need to be repaired as quickly as possible and work can continue.
• It is sold in dry or prepared form. The second option is preferable for those who have little experience in working with such compositions, and therefore the application speed is low. Dry putty should be diluted with a drill at medium speed and small quantities. After mixing the mixture, it is immediately applied to the wall. The edges are completely smoothed out, bringing them to “zero”.
• The finished solution is sold in bags or buckets. There is no need to keep the entire container open during work, but it is advisable to take small portions into an additional container.
• Putty is applied to the walls in a thick layer. To do this, take the mixture with a spatula and attach it to the wall using a spray. As a result, it should fill the entire wall very tightly, with virtually no gaps. And it is immediately leveled with a wide spatula. Movements are made smooth without too much pressure. It is necessary to achieve smoothness and evenness of the layer. The first layer is aligned horizontally. As a rule, it is enough, but if a second layer is required, then it is applied only after the previous one has completely hardened. Align it vertically.



• Having used the entire composition in the container, it must be cleared of the remnants of the old mixture, otherwise it will turn into hard lumps and spoil the next portion.

Tip: putty has poor adhesion to painted surfaces. Therefore, if the foundation has an old paintwork, then it is completely cleared. If that doesn’t work, then use a knife to make as many cuts as possible.

• Experts recommend using in a simple way How to achieve absolute smoothness of putty walls. To do this, it is moistened with a spray bottle or any other sprayer 15 minutes after completion of work. And immediately level with a metal spatula. In this case, a finishing layer of plaster is no longer needed and you can immediately apply paint or glue wallpaper.

Leveling the surface of the walls with cement putty

At its core, cement putty is similar to mortar. But only purified components are used for it, such as:

• fine sand that has been cleaned to remove large particles;
• high quality cement with polymer additives.

All this made it possible to create a solution of high quality and with the required elasticity. The setting time is longer than that of the gypsum analogue, so a larger area can be treated at a time, carefully leveling the surface.



Stages of work

• Cement putty is sold in dry form. To prepare it, you need to take the required amount of clean cold water and pour the mixture into it, stirring continuously. This can be done using a drill or manually. If the composition is not made according to the instructions, then in the end it is necessary to achieve a homogeneous mass with a viscous consistency.

Tip: if you need to level a large area of ​​walls, you can save money and prepare the solution yourself. To do this, mix cement of a grade not lower than M400 ¼ part of the mass and add fine-grained sand ¾ part of the mass.

• The walls are treated with a primer, and a thick layer of putty is applied to them by spraying with a spatula. And it is immediately leveled with horizontal smooth movements. For finishing treatment, 20 minutes after completion of work, it is moistened with water and smoothed with a spatula.



• It is recommended to check the surface of each layer using a level or a long rule.
• If the thickness of the putty layer is from 2 to 4 cm, you will need to use a painting mesh to strengthen it. With a layer of 5 cm or more, you cannot do without a special reinforcing mesh made of thin metal.
• The best way to level walls with plaster is to work with beacons. By setting them correctly, you can be sure of high-quality subsequent leveling with the mixture.

Aligning walls with beacons

Materials suitable for use as beacons:

• metal profiles specially designed for this purpose, which are sold in all hardware stores;
• To install string beacons, wire or thin cable is suitable.

Stages of work

• First of all, beacons are placed. Depending on the chosen method, they are attached to cement mortar or self-tapping screws. With this method of leveling walls, it is imperative to take care of an even rule, the length of which is at least 2 m. The distance between the vertical beacons must necessarily be less than the selected length of the rule.
• Dowels are attached to the top of the wall at the required pitch, and the lighthouse cable is tied to them. Having leveled it vertically using a level, a second dowel is attached from below, and the cable is pulled tightly between them. This cable will become a guide, under which a high track of cement mortar is applied so that the string is fixed on it.



• When the mortar is completely dry, the cable is removed, and the remaining cement mortar becomes the future beacon for leveling the wall.
• Profiles are attached in a similar way. But with the difference that they don’t have to be removed. If it is decided to remove them, then the resulting grooves are finally filled with putty.

Mixtures for leveling walls

Based on the composition of the mixture for leveling walls, they are divided into: cement, gypsum, polymer or complex. In addition, depending on what grain size is used in them: concrete, mortar or dispersed.

Until today, the most popular compositions were those based on lime, sand or cement. This is due to their low price, good ductility and moisture resistance. But they are increasingly being preferred to more modern polymer mixtures, which have better characteristics and are more versatile.

Composition of dry mixtures:

• binders, functional fillers. Their function is to prevent the solution from hardening too quickly. They also reduce the hygroscopic properties of the mixture;
• cellulose ethers. They must be present in the composition, as they are thickeners and prevent separation of the solution. To operate at subzero temperatures, antifreeze components are included;
• modifiers. They can radically influence the characteristics of the putty. For example, increase or decrease the hardening speed. If you plan to work with putty at high temperatures, you need to use a composition with an extended hardening time;
• aqueous inhibitors. Thanks to them, plaster compositions for leveling walls have high plasticity without adding a large amount of water. In this connection, the strength of the finished coating is significantly improved;
• polymers. This is the most important component. It is thanks to him that the adhesion of plaster to any surface increases. In addition, polymer components improve resistance to mechanical damage.



Advice: when choosing a dry mixture for leveling walls, you need to pay attention to the following characteristics:

• on the size of the sand fraction in the composition;
• per brand of cement. It is designated by the letter "M" followed by a numerical value. The higher it is, the better quality cement used, but its price is also higher. To level the walls in an apartment, you should not overpay for M400 or M500, which are intended for load-bearing walls. The composition marked M 150 is quite sufficient;
• for the presence of polymer additives.

Cement-sand mixtures for leveling walls

• In factory conditions, polymers are always present in its composition. When making it at home with your own hands, dishwashing liquid is added as a plasticizer. The cement-sand composition is universal and suitable for use in rooms with high humidity.
• For rough leveling, a cheaper mixture containing coarse sand is suitable. To create a smooth surface, you need to choose a finishing putty with fine sand.
• The main advantages are the low price and the ability to do it yourself, as well as suitability for work by a person with no experience.



Disadvantages include poor adhesion to concrete base, prolonged drying, as well as a fairly high probability of cracking. The composition is viscous and heavy, which makes working with it physically labor-intensive.

Cement-lime mixtures for leveling walls

• Their properties are similar to gypsum plasters. Instead of sand, it uses lime, which gives the solution elasticity, preserving its quality longer.
• Lime prevents the appearance of mold and mildew on the walls and regulates the level of humidity in the room. Unlike the previous composition, it adheres well to concrete without preliminary preparation. And if necessary, drill a hole in the wall, it will not crumble.

Disadvantages are a higher price than sand mortar and low compressive strength.



Gypsum mixtures for leveling walls

• This is an excellent option for use on walls in residential areas with normal humidity. When applied, an environmentally friendly and vapor-permeable layer is formed.
• In addition to its plasticity and ease of use, it dries quickly, which reduces the time of repair work, and also has sound and heat insulation characteristics. Suitable for leveling walls where there are differences in height up to 6 cm.

But still, the high cost, hygroscopicity and rapid setting make it less universal.

Heat-saving mixtures for leveling walls

Today you can find these on sale. This is an excellent option for apartments in panel houses, where the walls are quite thin and do not have additional insulation.

• Heat-saving plaster is made on the basis of a dry cement-lime mixture with the addition of perlite or polystyrene foam beads. They are suitable for rough leveling and require application over a finishing leveling layer.
• To achieve the desired effect, the layer of such plaster should be 10 cm thick. But due to low adhesion, it is recommended to spray it first. To do this, the mixture is diluted more liquidly (the consistency of sour cream) and sprayed onto the walls with a layer of 2-3 mm.

Tips for purchasing a composition for leveling walls with plaster

• It's better to pay more but buy plaster famous manufacturer, which has recommended high quality of its products.
• For leveling walls made of foam concrete, a gypsum composition is best suited. It quickly absorbs moisture from the applied composition, so at the end of the work, water is sprayed on top so that the composition does not crack.



• Although gypsum plasters are more expensive, their consumption is more economical. So, on average, to level 1m2 of wall you will need 15 kg cement composition and only 10 gk of gypsum.
• You should not buy the entire volume of plaster at once (if you need a lot). First, try it out and if it’s convenient to work with, buy the rest.
• Improper storage damages the plaster. Gypsum begins to set too quickly, and cement begins to slide off the wall when applied.
