Today it is difficult to imagine a quality repair without plastering the walls. In principle, you can do without plaster. If we are talking about repairs in a panel house, it is quite possible to use putty there (but even then not in any case), but if we talk about brick houses, then in them without a powerful plaster layer, a quality repair simply will not work. Modern types of plaster are designed to carry not only a finishing, but also a decorative function. Thus, to create a beautiful and reliable home, you need to correctly select the appropriate plaster for repairs.

Its main purpose is known to everyone who has ever encountered the problem of correcting irregularities on the walls. House builders are not always able to do the job in good faith, so in domestic buildings there are often walls with pronounced irregularities and roughness, and which may even deviate from the norm in terms of level. Here, to eliminate all these problems, plaster mixtures are used.
Currently, the modern market is able to offer a huge range of plaster, ranging from construction to decorative. There are three main types in total:
As part of the plaster of any kind there is a binding base, which attaches the entire mass to the walls, and it is also designed to ensure reliable contact with the bearing surface after drying is completed.
Cement plasters – they are the most popular on the market and combine operational durability, ease of use and cheap price. They can be used for both interior and exterior decoration. This solution, in principle, can be made independently if Portland cement is available. It only needs to be diluted with sand of various fineness, which will act as a filler. The advantages of these solutions are called high resistance to adverse weather events, they perfectly tolerate both summer heat and winter frost. Their disadvantages are the occurrence of cracks that form after drying (you will have to close them up with putty). Among other things, cement-based mixtures cling weakly to concrete bases, so when plastering walls in a panel house with such mixtures, you will need to tinker pretty much or choose a different composition. An additional disadvantage will be that, as a result of their excessive mass, they can shrink and practically “slide” along the wall. Finishing cement plaster is best done with a primer.
Gypsum compositions - in them, gypsum acts as a binding base, which, upon contact with water, becomes viscous and has greater adhesion to the surface than cement.Gypsum fractions are somewhat smaller compared to cement, so this solution can even serve as a putty. After applying such a composition and drying it, the surface becomes very smooth and does not even require finishing sanding. It is possible to immediately stick wallpaper or apply paint on such a surface, however, it is better to play it safe and prime it. Gypsum dries extremely quickly (about twice as fast as cement), which significantly saves repair time. The disadvantages of plaster based on gypsum include its poor resistance to moisture. It is simply not recommended to use these solutions in bathrooms and bathrooms, as well as an external finishing material. However, for indoor living spaces, this will be an excellent option. Nevertheless, gypsum is also poorly resistant to mechanical stress and is afraid of strong blows or cuts.
Lime mortars - they differ in the complexity of application, but, in turn, are considered extremely environmentally friendly. They are used for finishing various types of surfaces (and even wood). Such mixtures have excellent antibacterial properties, which makes them indispensable for finishing rooms with high humidity.
Acrylic plaster used as a decorative option. It lays down quickly and dries quickly. However, it is extremely sensitive to ultraviolet rays, therefore it is necessary to avoid permanent exposure of the treated surface to direct sunlight.
Silicate compounds - they are prepared on the basis of liquid glass. Perfectly pass gaseous substances, including steam. After drying, they do not form cracks at all, they mainly play a decorative role.
Silicone plasters – perfectly adhere to different surfaces, providing the maximum level of adhesion. Resistant to aggressive environments and substances with acid-base properties. They also play the role of a decorative finishing material.
Mineral solutions - are intended for better adhesion to the materials that will be used for final finishing. Its structure includes small chips, which helps different materials better adhere to the surface.
Each composition has its own texture. First of all, this applies to decorative plasters. So, on the basis of cement plaster, you can perform original decoration in the styles of "bark beetle" or "fur coat", and after painting them (the walls) will generally look like an exclusive design idea. Thus, if the goal is not to complete the original finish, then there is no need to spend money on expensive compositions.
In addition, you should pay attention to the mass of the composition and, before applying it, once again make sure that the walls can withstand it. If it is planned to process a thick layer of walls from thin-block ASGs, then it is necessary to select a lighter solution.
At the same time, you should pay attention to the type of surface where the plaster will be laid. An incorrectly selected composition will not achieve proper adhesion, and after drying, the entire wall may even collapse. Therefore, when buying a mixture, you should familiarize yourself with the manufacturer's recommendations and with what type of surface he advises to treat with this composition.
Before plastering, you need to make all the necessary measurements of wall deviations using plumb lines and levels. You also need to calculate the required volume of the solution in advance, but it is better to take it with a margin.
Plastering bathrooms will depend on the material from which the walls are made. The main condition that will be presented to the mixture is that it must have water-repellent properties, because there will be constant contact of the walls with moisture in the room. An excellent option for finishing such premises is tile. In a relatively dry bathroom or in a well-ventilated shower room, a water-repellent gypsum mix can be used for finishing. Nevertheless, despite the fact that it repels moisture well, it is still prone to destruction over time.
In this case, the cement base will become a more versatile tool and the best option for finishing the described premises. It can be produced in various modifications, depending on the wall material:
To process the ceiling and the water pipes located near it, you will need a silicone-based plaster for wet rooms with special inclusions. Such a building substance is called sanitizing and is characterized by high performance properties.
Ideally smooth walls can be achieved not only with the help of drywall, but also with the help of special plaster solutions. The choice of funds will depend on personal preferences and be determined by the material from which the walls are made. For leveling large areas, it is preferable to use a lime or cement base. To level walls with small cracks and potholes, the following types of plaster can be used:
Before pasting the walls with wallpaper, they must be leveled to hide cracks and depressions, fill the seams between the masonry, etc. Otherwise, due to an uneven surface, the wallpaper may overlap or, conversely, a gap may form between the joints of the two canvases. Among other things, plastering the walls will give them additional thermal insulation properties and will not let cold air into the room, and warm air will not let it out.
Often, plaster can be confused with putty.They, of course, are a bit similar in their properties, but there is also a significant difference - the plaster mixture is used to treat surfaces with a high level of curvature and it has more properties of facade plaster, because there is a filler in its structure. Putty, on the contrary, has a smoother structure and is applied over the plastered surface in order to smooth out the graininess of the latter.
At the same time, there is no single answer to the question of the best plaster for apartment walls. In each particular case, everything will depend on many parameters: wall material (brick or concrete), expected operating conditions (high humidity, standard temperature conditions) and many others. In any case, in order to achieve the highest quality result, no one forbids combining different types of mixtures.
To make a decision on the use of a particular type of mixture for finishing (dry or wet), it is necessary to determine the properties of the coating to be processed. Dry plaster is often referred to as drywall, and wet is the alignment of walls with a liquid solution. When using the former, the thickness of the coating must always be adjusted, which is in direct proportion to the level of surface roughness. Each designated type has its positive and negative sides.
The structure of drywall includes three layers: cardboard itself, a gypsum layer and cardboard again. It can be used not only for trimming wall surfaces, but also for arranging suspended ceilings, as well as window and door slopes and various partitions. Its merits are as follows:
Its disadvantages include the possible occurrence of cracking, the lack of resistance to hot steam and moisture, the difficulty of attaching various accessories to its surface.
Wet plaster is often called monolithic, which is due to the fact that upon completion of drying, it leaves a perfectly flat surface (without joints). Such processing takes much more time than laying drywall sheets. The master must manually apply the finished mixture to the wall surface and properly level it before it dries. The advantages of wet plaster include:
Decorative plastering is used as a finishing wall covering. A wide range of textures and colors allows you to choose a specific plaster type for the desired interior. According to the basic connecting element, again, it can be divided into:
mineral solutions are prepared on the basis of cement, and special mineral elements, marble chips, etc. are added to their composition. It is produced as a standard in the form of a dry powder, which must be diluted with water before work.This coating has a high degree of adhesion to the surface, and it can easily be given the color and texture of any material (wood, drywall, plywood, etc.). The advantages of such a coating can be called excellent resistance to mechanical damage, environmental safety, fire resistance and increased strength.
into the structure silicone mixtures are mixed with resin, which makes the structure of the material more original (“bark beetle”, “lamb” style). Due to its elasticity, it is very convenient to work with such a mass. It passes steam well, is resistant to moisture, has UV protection, can be self-cleaned and does not collect excess dust. Even if dirt gets on the coating, it can be easily removed with a damp sponge.
Acrylic solutions are made on the basis of acrylic resin. They resist temperature changes well, are not subject to cracking, and are sold immediately ready-made. But it is strictly not recommended to cover walls that are insulated with mineral wool with this solution.
AT silicate liquid glass is added to the mixture, so the mixture becomes elastic and durable and does not crack over time. And taking care of it is as easy as shelling pears: to clean the dust, you can simply wash the wall with any detergent. The mixture itself dries quickly, so professional skills will be required to apply it to the walls.
The structure of this sample contains reinforcing fibers and water-repellent elements. Equally well suited for both exterior and interior decoration. Excellent performance is observed on various surfaces: brick, concrete, aerated concrete. Does not form cracks after drying.
