The best primer. The main mistakes that even experienced builders make

Several types of primers are produced in our country. Concrete contact is often used in work. It is a really good primer, but is primarily intended for concrete, smooth surfaces.

Some builders use this soil everywhere and everywhere. But in most cases it is not needed and even reduces adhesion.

It happens that builders complain that the cement plaster "fell" from the wall. At the same time, they were primed with expensive concrete contact. Therefore, it is not recommended to use this primer with cement plaster or tile adhesive. Ceresit CT16 primer belongs to the same class. It is white in color, but made as a concrete contact.

Those who think that it is possible to abandon the primer are mistaken. After repairs, they may depart wallpaper, fall off tile, crack paint, plaster.

Primers strengthen the base. Essential for loose and porous surfaces. After priming, the materials are easier to apply, and better attached. The resistance of the walls to moisture increases. The primer does not allow mold and rust to appear.

It is convenient to apply the primer with a garden sprayer.

Most use rollers or a wide brush. A microfiber roller is ideal. But for large volumes, specials are suitable. equipment - an apparatus for airless painting or cheap spray guns.

Errors

1. The main mistake when working with a primer, which even experienced builders make, is applying several layers of primer. More does not mean quality. Craftsmen apply 10 coats of primer to create a glass wall effect. The surface becomes non-vapor permeable.

2. Avoid smudges when applying. For example, apply primer with a roller, it starts to flow at the joints. As a result, it will be noticeable after painting.

3. Do not store the primer diluted with water for a long time. Microorganisms can start and it just deteriorates.
