Gypsum and a qualitatively made putty smooth enough to glue wallpaper on them without additional processing. Then it turns out that the consumption of glue to 1m2 exceeds the calculated standards. After time, deciding to change the wallpaper, it is found that they are removed with the top layer of plaster, and quickly make cosmetic repair does not work. To avoid such trouble will help primer deep penetration. It fills the pores in the surface of the walls, and the glue consumption will be less. The film formed from above will allow you to carefully remove the old coating and quickly update the interior with your own hands.
Grinding deep penetration
Primer, deep penetrating into the porous surface
Ground wall
My friend is finishing his home. Trying to do if possible with your own hands. He came to me with a question, which primer deep penetration is better and how it acts, its characteristics. What will happen if the ground does not use and what differs different types of impregnation. Vadik was interested in the composition, safe for residential rooms and resistant when conducting outdoor work. Primers must correspond to GOST R ISO 9001-2001. I showed a friend where it is written on the reverse side and advised to always look.
The primer of deep penetration is absorbed into the material of the walls on a greater depth. It remedies the surface, filling the pores. From the top with drying, a solid film is formed. As a result:
- The loose structure of the treated surface is reinforced;
- decreases the consumption of glue and paints on m2;
- Woods of wood and plastered acquire moisture resistance;
- The paint falls to a smooth layer and dries faster;
- improves adhesion;
- Walls breathe;
- Supplements are protected from fungus, mold, insects;
- Wallpaper and paint with subsequent repair are easily removed;
- Finishing longer saves gloss and fresh look.
Manufacturers create mixes in their recipes. The most popular impregnations from firms optimist, prospectors; Lacra, Axton. Deep penetration primer has a safe composition for human health:
- resin;
- adhesives;
- bitumens;
- oils;
- Drying accelerators.
For beginner masters, who for the first time make repair walls with their own hands, it is more convenient to use primers containing pigments. Then it is clearly visible, the entire surface of the tree is covered or there are skipping.

Drying accelerators may not be included in the impregnation. You can buy an additive yourself. I showed a friend that there are primers for wood, brick and metal, as part of which these substances are not indicated. We added practically pipette. It is worth pouring the accelerator more, and the gloss disappeared, the surface became rough.
Acrylic-based primer
Independent finishing of the walls of the primer
Inside the house in residential rooms, we used acrylic primer deep penetration used for internal works with their own hands. It is without a strong smell, well absorbed into the surface. You can work in the range of temperatures from +5 to +30 degrees. The composition is used on an acrylic basis for outer walls, work can be performed in the summer.
In terms of its action, acrylic primers of deep penetration can be called simultaneously:
- penetrating;
- strengthening;
- antiseptic;
- Universal.
Fungicides and other additives are added against the destruction of insects and mold. Anti-grapple and antiseptic mixture does not allow larvae and it's time to develop inside the tree and other wall material. A large selection of protective impregnations is provided by the company Optimist, Knauf, Cerezite. There are compounds against mold and Axton and Lacra companies.
The composition for external work and, raw interior premises add substances that repel water. Antistics do not give dust linger on the surface of the walls.
Acrylic composition for impregnation of walls from various companies is distinguished by consumption and how much time will dry the layer. To select the optimal option and purchase all the materials of one company, Vadik made the table.
| Name of the primer | How much dries, hour | Consumption, ml on 1m2 | Used on materials |
| Optimist | 2. | 100 - 250. | Tree, Brick, Concrete, Plasterboard, Plaster |
| Cerepes | 4 - 6 | 100 - 200. | Tree, Brick, Concrete, Cement, Stone, Plaster |
| Knauff | 3. | 70 - 100. | Concrete, Cement, Plaster, Plasterboard |
| Lacra | 3. | 50 - 100. | Brick, plaster, concrete |
| Bolls. | 12 | 80. | Tree, Brick, Plaster, Gisokarton, Gypsum, Concrete, Cement |
| Axton. | 2. | 100 | Tree, plaster, concrete, cement. |
For materials with loose texture: wood, foam concrete and others, adhesive add to the primer. It fastens cracks and pores, increases the strength and service life of the material. From the correct impregnation selection depends on how much the coating will last and when the next repair is.

The primer of deep penetration for outdoor and internal works is sold in plastic containers of different sizes and you can buy as you need to repair with your own hands. For example, the composition of an optimist with antiseptic additives is packaged 1, 5, 10 liters. They are acquired by those who want to make repairs with their own hands. For professional use, the capacity of 50 liters is sold. Combines this group of materials branded sticker optimist green.
The reverse side is indicated:
- GOST;
- The basis is acrylic;
- structure;
- For which walls and floors are applicable;
- Additional components;
- flow per 1m2 or how many surfaces in m2 can be coated with 1 liter of composition;
- Additives against mold and fungus;
- color when applied and after complete drying;
- how much will dry before applying the next layer and how much to complete hardening;
- Optimal temperature for storing and conducting outdoor work.
In addition, there may be other information, for example: is there a latex additive, there is no smell, the diluent type used tool.
For concrete need a special composition
Breasting the walls with your own hands
Concrete refers to weakly moisture materials with poor surface clutch and porous texture. The relationship between cement and other components is weak, destroyed from shocks and friction. Deep penetration primer for concrete has a special base, a composition with small molecules. They are able to penetrate the space of an intercrystalline lattice and strengthen the internal connections of the material.
Penetrating primer as an additive contains glue. They strengthen low grades concrete to 600m. Adhesion is improved by quartz sand. It creates a rough surface of the walls under the tile and the floor for the fill. How much the first layer of the concrekont contact is indicated on the container. Apply the coating is recommended by a tough tassel and rub well.
After applying the second layer, wait until complete crystallization of the composition. Using drying accelerators cannot be used. Moisture and pairs are poorly passing through a weakly sprinkling surface and acceleration can lead to a violation of the integrity of the film. Therefore, at Vadik, we accounted in advance how much the composition is dry and the schedule of work.

Properties and quality of composition are determined by standards. The primer of deep penetration technical characteristics has according to GOST 21751 and for the concrete outer coating GOST 20811:
- consumption per m2;
- viscosity;
- interlayer drying time;
- After how much you can start moving;
- Strength of film for erasing and gap.
The primer of deep penetration may contain coloring pigments and used as final finish. It does not contain sand. We used such a composition in the garage and boiler room. Paul in these rooms do not need to decorate.
Walls from wood need to strengthen and protect against insects
Finishing the walls of deep penetration
The tree absorbs water, is a graceful environment for the development of mold and fungi. Insects and rodents love to settle in warm material. Therefore, the composition for wood contains a large set of protective additives. The impregnation consumption on M2 exceeds the cost of primer for walls from other materials.
Optimist and Lacra manufactures various wood mixtures:
- strengthening;
- penetrating;
- strengthening;
- universal;
- Anti-gribrous.
All of them contain fungicides, only in different proportions. From how much added certain substances is added, the individual qualities of the composition are enhanced. Latex and bitumen resin are added to the water resistance.
Optimist offers budget soils
Breasting the walls room
Company Optimist offers primers for various materials. They contain components against mold in mixtures for work inside and outside. Protecting walls from moisture, it passes the air and allows them to breathe. Saving the primer optimist is equally on all materials - 2 hours.
Consumption on M2 depends on porosity and selected tool. For the walls, the deposition of primer sprayer reduces consumption by an average of 10%. To remove fungus and mold in old buildings, additionally optimist produces special impregnations.
We decided to stay with a different product on this company's products. They took everything complete, including the primer under putty and the finish finish. Also bought glue for wallpaper and paint. Materials of one firm are better combined with each other than from different manufacturers.
