One of the most widely used options for finishing buildings - decorative facade plaster. It creates a layer that protects the walls from external environmental influences and does not need further refinement. With this coating at the same time hide unevenness and decorate the walls. From the choice of material and the quality of the application depends on how the building will look.
This method of decoration is very valuable for the ease of application, resistance to temperature changes, relatively low cost, the possibility of creating an interesting texture and a wide color palette. Building mixtures of the new generation greatly facilitate the work of the masters and allow performing very complex and diverse facade facades.
Traditionally, the cement plaster is used for the primary leveling of the walls.

Properties of decorative protective coatings
The produced mixtures abound in variants of textures, colors and degree of readiness for use. Filler
always is a crushed stone of different fractions - from sand to 5 mm grains, but the binders can be different:
- Cement. They are considered the cheapest. A small selection of colors (white and gray colors), because there are few stable pigments, and the rest fade in a few seasons, but it is possible to tint with silicate paints. Allow walls to "breathe", but protect them from moisture, incombustible and undemanding in application. In case of mechanical damage, microcracks may appear. Effectively look when using brilliant additives and marble chips, but this greatly increases the cost. The service life is 10-30 years.
- Silicate. Steam-permeable and therefore suitable for porous walls (eg aerated concrete). The astringent is called "liquid glass", because after hardening it acquires the same properties. Due to the fact that they are rapidly frozen, they are capricious in their work, therefore they require high skill for the application. Repel dust and easy to clean. Durable - promise up to 50 years of faithful service.
- Acrylic. Ready-mixed based on acrylic resin, dissolving in water. Moisture-proof, therefore suitable for regions with high humidity. Resistant to the development of fungi and mold. Easy to work, because they are elastic and adhere well to the surface. Elastic, do not crack when deforming the walls. Disadvantages are: combustible, low vapor permeability, dust and dirt easily adhere to the surface. Operated for 15-25 years.
- Silicone. Ready mixes for making coatings are not thicker than 4 mm. Binder is a silicone resin - a kind of rubber, which gives excellent adhesion to the surface and high resistance to mechanical stress. High vapor permeability, therefore can be used on almost all surfaces. Universal material with dirt-repellent properties, allowing for a long time to maintain a decent appearance of the building. Resistant to ultraviolet light. Easy to clean in the rain. Durable, it serves up to 60 years, but is not too popular because of its high cost.
The composition of silicone plaster includes crumbs of specified sizes and adhesive solution. Mixtures are designed for thin-layer decorative coating: concrete, gypsum, wooden, wooden bases.

How to choose the right plaster?
The walls of the house can be made of any building material, but the outer covering must necessarily correspond to it. Several types of decorative facade plaster are available, so you can choose the right one for any walls.
The choice should be answered responsibly and thoroughly, taking into account many factors: financial possibilities, aesthetic preferences, the surface structure of the application and the priorities of the owner of the house.
For example, no matter how strong a coating with an acrylic binder, it quickly burns out, so it will need to be repainted every few years. If the owner likes diversity and is going to change the color of the house often, then for him such a question will be insignificant.
Cement decorative plaster for the facade is applied in a thick layer, but the acrylic and silicate ones belong to thin-layered ones and are therefore more demanding on the substrate to be applied. It will have to be covered with a coloring primer in the color of the future plaster.
If you plan to decorate the facade with decorative plaster yourself, you need to carefully prepare. This is a painstaking work, on which the appearance of the dwelling depends, its "packaging", which creates an image for the owner of the room, tells about his prosperity and taste. Only with a competent approach can the walls of the building be decorated, and they will serve for many decades.
