Primer for walls - a guarantee of a good result

When carrying out repairs, a primer for walls is used. It usually consists of a solvent, a binder and special additives that determine the purpose of the solution.

Wall priming is carried out before coating. It removes dust and excess debris, impregnates the walls for their greater protection and better adhesion to the finishing material. Solutions can be sold both in finished form and in the form of a powder, which must be diluted with water or a solvent. According to their application primers are divided into several types - depending on the work that will be carried out after their application.

Primer for walls, which is applied before painting, is universal: it is excellent for any type of paint. But there are also materials that are used only for indoor or outdoor works.

There are special primers for drywall that impregnate it, make it firmer and protect it from moisture. Such a tool is applied to it before puttying or before wallpapering. Even moisture resistant gypsum cardboard should be treated with such a primer after it is installed in rooms with high humidity.

The wood is treated with a primer based on antiseptic - it protects wood from decay and fungus formation. Also such impregnation for a tree makes it smoother, which contributes to a better application of the decorative protective coating.

To protect metal structures, a special metal primer is used. It deeply impregnates the substrate for better adhesion, and also protects it from corrosion. Usually the composition of such solutions includes aluminum powder, which makes it possible to use them for any metal, and not only for iron. Some of these primers are used as an independent coating, and others - as a basis for decorative protective coatings.

Primer for walls consisting of smooth concrete, is a special solution of deep penetration, which provides adhesion to the finish coat. It is used in monolithic buildings or on concrete blocks. Without its application, coatings actually do not hold on such walls.

In a separate view, it is possible to include "Aquastop" primers. They are used at high humidity and suitable for any porous surfaces. They strengthen the base, reduce the consumption of paint or varnish, and also have antiseptic properties.

Some masters use plain water instead of a primer during repair. In a sense, it helps, because dust and excess debris are removed from the wall, and the finish coat holds a little better.

But in everyday life, people often use universal primers. Such a primer for walls is excellent for almost all surfaces (except for monolithic concrete), provides good protection and adhesion. Before puttying or painting the walls, they must be treated, otherwise the coatings can peel off after a while, and if it's a wallpaper, then they can start bubbling.
