Primer for walls - what is it for?

Priming of the floor and walls is not required at all. It is done only if you want to create a truly high-quality and reliable coverage. Primer allows to significantly increase the adhesion properties of the substrate, that is, it creates good adhesion of the surface with further finishing materials, whether it is wallpaper, paint, putty. Plus, it makes the coating more reliable and qualitative.

With further use, it prevents processes such as shedding, cracking, the appearance of stains and stains. Also, the walls treated in this way are absolutely not afraid of humidity.

strengthening and adhesion .The first is designed to strengthen porous and loose surfaces. The second one is for better adhesion of the base and finishing decorative coating.

When choosing a mixture, it is necessary to take into account not only the physical parameters of the treated base( looseness, porosity), but also the chemical composition.

In general, the primer is divided into the following types: universal, acrylic, alkyd, mineral, shellac, for metal .The most popular is the first, it is used for complex works for finishing large premises.
