- Mineral. It is a cement-sand mixture to which polymers are added to improve the elasticity and adhesion of the plaster. Mineral facade plasters are easy to apply, vapor-permeable, and have water-repellent properties. Due to their vapor permeability, mineral mixtures are suitable for insulating facades using both basalt wool and foam. The disadvantages of mineral plaster include a small resistance to mechanical damage and fragility - after 10 years, they will definitely have to be repaired, because cracks appear quite quickly. In addition, mineral mixes for facades are sold mainly in bags and in white, you have to paint on top
- Acrylic. Such facade plasters are based on acrylic resins. This type is considered the most resistant to mechanical damage, the facade can last up to 25 years. However, acrylic plasters are vapor-resistant, therefore they are not suitable for thermal insulation of facades with mineral wool. The disadvantages of acrylic mixtures include the fact that they attract dust, which is not washed off by rains. This leads to a deterioration in the appearance of the wall
- Silicate. This facade plaster, in contrast to acrylic, repels dust, washes well, which allows you to keep the original appearance of the facade for many years. Plastic, durable, created on the basis of aqueous potassium glass with the addition of plasticizers. It is the plasticity that makes the silicate plaster crack-resistant
- Silicone. This type of facade plaster is by far the most "advanced" and technologically advanced. It is created on the basis of silicone resin, an even more plastic version with high elongation rates and a long service life - up to 25 years. Silicone plaster is anti-static, easy to clean, can be used on the facades of houses next to dusty roads

Facade plaster can be divided into four types:
Mineral. It is a cement-sand mixture to which polymers are added to improve the elasticity and adhesion of the plaster. Mineral facade plasters are easy to apply, vapor-permeable, and have water-repellent properties. Due to their vapor permeability, mineral mixtures are suitable for insulating facades using both basalt wool and foam. The disadvantages of mineral plaster include a small resistance to mechanical damage and fragility - after 10 years, they will definitely have to be repaired, because cracks appear quite quickly. In addition, mineral mixes for facades are sold mainly in bags and in white, you have to paint on top

Acrylic. Such facade plasters are based on acrylic resins. This type is considered the most resistant to mechanical damage, the facade can last up to 25 years. However, acrylic plasters are vapor-resistant, therefore they are not suitable for thermal insulation of facades with mineral wool. The disadvantages of acrylic mixtures include the fact that they attract dust, which is not washed off by rains. This leads to a deterioration in the appearance of the wall

Silicate. This facade plaster, in contrast to acrylic, repels dust, washes well, which allows you to keep the original appearance of the facade for many years. Plastic, durable, created on the basis of aqueous potassium glass with the addition of plasticizers. It is the plasticity that makes the silicate plaster crack-resistant

Silicone. This type of facade plaster is by far the most "advanced" and technologically advanced. It is created on the basis of silicone resin, an even more plastic version with high elongation rates and a long service life - up to 25 years. Silicone plaster is anti-static, easy to clean, can be used on the facades of houses next to dusty roads

We wrote about the choice of paint for the facade. So, in the case of mineral plaster, it is best to choose silicate paint, which will additionally protect the walls from cracking.
It is important to remember that the smoother the surface, the easier it is to crack. A rough facade will last longer. In our country, the most popular options for plaster texture are corrugated "bark beetle" and a rough "lamb". "Bark beetle" contains pebbles, this type of texture is often called pebble plaster. The "lamb" can be formed with a roller, simply with a twisted rag, a broom or a scraper, which will provide a different arrangement of lumps of plaster.

Important! Gypsum plasters are intended exclusively for indoor use!
As for the price, the most affordable is cement-based mineral plaster, that is, the first type we have described. The most expensive is silicone.

We must not forget that the plastering of the facade is carried out only after the complete shrinkage of the new house has occurred. Of course, first you should complete all work with the roof and wiring communications. The facade must be cleaned of salts, grease and dust, and primed. If the plaster is applied in dry and hot weather, the wall surface should be moistened. The most difficult thing will be to apply a layer of plaster to the mineral wool, if this material was used to insulate the facade.
