During the construction and repair, the materials of the walls must be strengthened, protect against moisture penetration. The primer for the facade simultaneously increases the adhesion and retains the vapor permeability of the walls. As a result, the finishing material is well held. Painting and glue consumption decreases. The preservation of masonry and finishing increases. The appearance of the building is improved due to the smooth tone of the decorative coating. All incoming deep penetration primers and smooth surfaces comply with the requirements of the GOST OF THE RF security and environmental friendliness.

Walls in varying degrees are hygroscopic. They are destroyed from moisture and frost. The primer deep penetrates the brick and wood. It creates a protective film, binds fragile particles together, strengthening the texture of the wall. On smooth surfaces of the type of concrete, a rough coating is formed, which improves adhesion with glue and paint.
As a result of the use of primer facade for smooth surfaces and deep penetration, specifications are improved:
- The surface strengthens;
- Adhesion improves - adopted adhesion;
- protects against mold, fungus, insect destruction;
- The flow rate of the adhesive and paint decreases;
- increases the ability to push water;
- The coating layer falls smoothly;
- The decorative surface acquires uniform tonality and gloss.

All compounds used in construction must comply with GOST. Therefore, the mixtures of protective and deep penetration is not recommended independently. When buying protective compounds, pay attention to its application. Fixing mixtures with protective properties are intended for porous and fibrous structures:
- brick;
- wood;
- Penals and aerated concrete;
- a natural stone;
- Cement-sand solutions.
Metal, glass and ceramics have a dense surface. They are covered with soil to create a rough surface, improve adhesion.

The flow rate of deep penetration in accordance with GOST is measured by calculation per unit area. The facade or for internal work is indicated on the package next to the base, for the processing of which it is intended.
Composition of facade primers
Deep penetration primer facade
The mixture for the facade, regardless of the depth of penetration, has a complex composition. In addition to the main component, it includes various additives depending on the porch of the wall element to which it is applied. For wood, these are anti-epires and antioxidants protecting insects and moisture. Technical characteristics of stone and concrete improve the binders for outdoor work.
According to the main binding component of the primer for external and internal works:
- acrylic;
- Alkyd.
Both materials correspond to GOST. Alkyd is sold ready for use and differs in the depth of penetration into the material. It is the optimal option for wood. Acrylic for the convenience of the work can be diluted with water and apply to the crawle. When finishing the facade, four groups of protective bonding compositions differ. Their characteristics, application and consumption are shown in Table:
| Type of primer | application area | Consumption, ml / m2 |
| Alkyd facade | tree, chipboard, dvp, cardboard, | 100 - 120. |
| Acrylic facade | plaster, wood, brick, stone, aerated concrete | 120 - 150. |
| priming | metal | 80 - 120. |
| Deep penetration | tree, brick, stone | 100 |
The consumption of primer depends on its viscosity, the depth of penetration and the porosity of the material to which is applied. The air temperature should be above 5 degrees. In the frost, water crystallizes and destroys the structure. Evaporation and drying does not occur. The binding component is frozen, loses the ability of particles clutch. Goste determined the temperature limits of external work. They must be indicated on the packaging of each type of primer.
Characteristics, composition and GOST requirements
Finishing walls of facade primer
Requirements and specifications are indicated in GOST ISO 9001-2001 of the Russian Federation in the section on construction and finishing materials for external work. The primer of deep penetration includes resins. They bind to each other particles of material. Antipirens are protected from moisture penetration. Antistatics kill pores fungus and mold. Depending on the material and climatic zone, other fillers can be introduced.

Holding the amount of primer that you will need for work, make measurements of all walls and socle. Calculate the area of the coating, deducting door and window openings. Round up to a larger number of containers in which the primer of deep penetration is sold.

The resulting quantity must be added at least 5%. This unrecorded consumption is associated:
- the error of measurements and calculations;
- a deeper layer of impregnation of material by primer;
- non-compliance of the temperature calculation according to GOST;
- Unforeseen spending material.
Acrylic mixture for outdoor work
Primer facade at home
The composition of the acrylic protective mixture is represented by a colloidal solution of polymer resin and water. Plant components, wax, dyes, fibers, sand and abrasive materials are added to give certain qualities. When dried after applying the primer, the water evaporates, and the composition inside is polymed. It connects particles of material and creates a protective film and the necessary texture.
The technical characteristics of the coating acrylic primer for external work depend on the additives. For metal and other materials with a smooth surface and a low liquid absorption coefficient, quartz sand is added. It creates a rough surface, which is easily held with putty and paint. GOST is prohibited from staining of smooth water repellent materials without preliminary processing of the soil.

Conconokontact has more soil. It is applied to concrete capable of absorbing moisture. To align the surface, various fillers are added to it, including cement and sand. Acrylic primer for concrete surfaces partially replaces the putty. It is applied in 2 and 3 layers on very uneven planes. Significantly improves adhesion and other plate characteristics.
