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), and if we talk about brick houses, then in them without a powerful plaster layer, a high-quality repair simply will not work. Modern types of plaster are designed to carry not only finishing, but also decorative function. Thus, to create a beautiful and reliable home, it is necessary to correctly select the appropriate plaster for repair.

Its main purpose is known to everyone who has ever faced the problem of correcting irregularities on the walls. House builders are not always able to do the job conscientiously, therefore in domestic buildings there are often walls with pronounced irregularities and roughness, and which may even deviate from the norm in terms of level. It is to eliminate all these problems that plaster mixes are used.
Currently, the modern market is able to offer a huge assortment of plaster, ranging from construction to decorative. In total, there are three main types:
In the composition of any kind of plaster 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 complete.
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 just needs to be diluted with sand of various fineness, which will play the role of 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 considered the occurrence of cracks that form after drying (they will have to be repaired with putty). Among other things, cement-based mixtures weakly cling to concrete bases, therefore, when plastering walls in a panel house with such mixtures, you will need to tinker a lot 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. It is better to use a primer to finish the cement plaster.
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 has a slightly smaller fraction than cement, so this solution can even function as a putty. After applying a similar composition and drying it, the surface becomes very smooth and does not even require finishing sanding. On such a surface, it is possible to immediately stick wallpaper or apply paint, however, it is better to insure yourself and prime it. Gypsum dries extremely quickly (about twice as fast as cement), which significantly saves repair time. The disadvantages of gypsum-based plaster include its poor resistance to moisture. It is simply not recommended to use these solutions in bathrooms and bathrooms, as well as as an external finishing material. However, for indoor living spaces, this will be an excellent option. Still, gypsum is also weakly resistant to mechanical stress and is afraid of strong impacts 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 lies down quickly and dries quickly. However, it is extremely susceptible to ultraviolet rays, therefore it is necessary to avoid constant exposure of the treated surface to direct sunlight.
Silicate compounds - they are prepared on the basis of liquid glass. Gaseous substances, including steam, are perfectly permeable. After drying, they absolutely do not form cracks, mainly they perform a decorative role.
Silicone plasters - adhere perfectly to different surfaces, providing maximum adhesion. Resistant to aggressive media and substances with acid-base properties. They also play the role of decorative finishing material.
Mineral solutions - are intended for better adhesion to the materials with which the final finishing will be made. Small chips are included in its structure, 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 make original decoration in the styles of "bark beetle" or "fur coat", and after painting them (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 make sure once again that the walls will withstand it before applying. If it is supposed to be processed with a thick layer of walls made of thin-block ASGs, then you need to choose 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 collapse in general. Therefore, when buying a mixture, you should familiarize yourself with the manufacturer's recommendations and with what type of surface he advises to process 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 solution in advance, but it is better to take it with a margin.
Plastering of bathrooms will depend on the material from which the walls are made. The main condition that will be imposed on the mixture is that it must have water-repellent properties, because in the room there will be constant contact of the walls with moisture. Tile is considered an excellent option for finishing such premises. In a relatively dry bathroom or in a well-ventilated shower room, a water-repellent plaster mix can be used for finishing. Nevertheless, despite the fact that it repels moisture well, it is still subject 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 water pipes located near it, you will need plaster for wet rooms on a silicone base with special inclusions. Such a building substance is called sanitizing and is characterized by high performance properties.
Perfectly flat walls can be achieved not only with drywall, but also with special plaster solutions. The choice of tools will depend on personal preference and will 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. The following types of plaster can be used to level walls with small cracks and potholes:
Before pasting the walls with wallpaper, they must be leveled to hide cracks and depressions, fill the seams between masonry, etc. Otherwise, due to the uneven surface, the wallpaper may overlap each other, or, conversely, a gap may form between the joints of 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 will not let out warm air.
Often times, plaster can be confused with putty. They, of course, are a little 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 other hand, has a smoother structure and is applied over the plastered surface in order to smooth out the granularity of the latter.
At the same time, there is no definite 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 (increased humidity, standard temperature regime) and many others. In any case, in order to achieve the highest quality result, no one forbids combining various types of mixtures.
To make a decision on the use of a particular type of mixture (dry or wet) for finishing, it is necessary to determine the properties of the coating to be treated. Dry plaster is often referred to as drywall, and wet is called leveling the walls with a grout. 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 species has its positive and negative sides.
The structure of drywall includes three layers: directly cardboard, gypsum layer and again cardboard. 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 advantages are as follows:
Its disadvantages include the possible appearance of cracking, 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). This processing takes much more time than laying drywall sheets. The craftsman must manually apply the finished mixture to the wall surface and properly level it until it is dry. The pluses of wet plaster include:
Decorative plastering is used as a finishing wall covering. A large assortment of textured and color solutions allows you to choose a certain type of plaster for the desired interior. According to the basic connecting element, it can again be subdivided into:
Mineral mortars 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 dry powder, which must be diluted with water before use. 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", style "lamb"). Due to its elasticity, it is very convenient to work with such a mass. It is highly vapor permeable, moisture resistant, UV protected, self-cleaning 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 extremes well, are not susceptible to cracking, and are sold immediately ready-made. But it is strictly not recommended to cover the walls that are insulated with mineral wool with this solution.
IN 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 remove dust, you can simply wash the wall with any detergent. The mixture itself dries quickly, so professional skills are required to apply it to walls.
The structure of this sample contains reinforcing fibers and water-repellent elements. Equally well suited for outdoor and indoor decoration. Excellent performance is observed on various surfaces: brick, concrete, aerated concrete. Does not crack after drying.
