How to use the primer

Decorative interior decoration, as is known, implies the mandatory preparation of wall surfaces for the application of one or another type of finishing material to them. Such preparation is usually done using a so-called primer, which penetrates deep into the pores of the treated surface and contributes to an increase in adhesion (adhesion) to the finishing decorative coating. Before using a primer, you should familiarize yourself with its main types, as well as with the application technique on the surface to be treated.

Advantages of using a primer

But, first of all, let's consider the additional benefits that this procedure gives us:

• primed walls will be reliably protected from damage that can be caused by removing old wallpaper, for example;
• such a coating contributes to a more uniform distribution of working materials applied to the surface (plastering, plasters or paints);
• the primer layer protects the treated surface from the appearance of fungus on it, corrosion and mold;
• certain types of primers can also be used as leveling compounds.

We draw your attention to the fact that there are two types of primers that differ in their intended purpose. A standard hardening compound (primer) is usually applied to plastered surfaces, if necessary, to paint the walls or before pasting them. The primer of deep penetration, relating to building materials of a high price category, is used most often for facade works, to the quality of which special demands are made.

Types of primers

By type of base used for the preparation of a primer mixture, all known compounds of this class are divided into the following groups:

1. Acrylic blends most suitable for domestic use. During their preparation, the initial dry powder is simply diluted with water, after which the resulting composition is applied to the surface to be treated.
2. Alkyd formulations based on alkyd resin and most commonly used to protect wooden surfaces.
3. Special primers for metal, the choice of which is determined by the type of metal surface.
4. Primers for concrete, used when applying enamel coating.

How to apply a primer

Since it is necessary to use a primer, you must be familiar with the technique of its application - we suggest that you briefly familiarize yourself with the procedure for the operations performed during this process.

First of all you need to worry about the preparation of the base itself, on which you are going to apply a primer mixture.

When preparing the surface for applying a primer, it is necessary to get rid of the remnants of the old coating using a large skin or a metal spatula, at the same time eliminating all the irregularities on the surface, as well as traces of grease, rust and dirt.

For subsequent operations, you will definitely need the following tool:

• two rollers used for applying a primer (with a short and long handle);
• narrow brush used in hard to reach places;
• spatula with a wide working part.

Before starting work, pour the required amount of primer mixture into the appropriate container. Her concentrate is diluted, as a rule, in accordance with the instructions given in the instructions for use.

Then, carefully dipping the roller with a long holder into the finished mixture, evenly “roll” the entire surface to be treated. In case of preparation of a thick mixture, it will be more reasonable to use a wide spatula. Corner spaces and hard-to-reach sections of the walls located behind the batteries are processed with a rough brush with a narrow working part.
