Primer for putty walls

Not a single serious repair in the apartment is complete without wall decoration. And although the technology for processing brick, concrete, drywall or wooden substrates is very different, at a certain stage do without putties Not sure it's going to happen. Regardless of how serious the walls require - large-scale alignment or elimination minimal defects - a primer for walls for putty will be a mandatory item in the list of purchased for repair materials.

Why prime walls before puttying?

Each owner of the apartment wants the finishing of the walls after the repair to look perfect as long as possible. And it doesn’t matter if the repair is done with your own hands or with the help of professional craftsmen. For this to happen, and you need a primer on the walls before puttying. The soil layer performs a number of important functions:

• In any material, whether it is concrete, brick, drywall or plywood, there are pores and cracks that the primer can fill and thereby strengthen the surface of the base.
• The primer composition increases the adhesion rate of the base, improves its adhesion to the putty mortar, because of which it does not crumble and does not peel off the wall for a long time.
• By filling the pores of the material with a primer, the filler consumption is reduced.
• When dried, the primer forms a thin, but very strong film, which does not allow any kind of stains to appear on the finish.
• Do-it-yourself putty lays on primed walls more evenly, it is easier to distribute on the wall surface.
• Primers with special antiseptic and moisture protective properties can reliably protect the walls in rooms with high humidity from the appearance and spread of mold, fungus and other harmful microorganisms.

The listed properties of the primer compositions give an unambiguous answer to the question of whether the walls should be primed before puttying. And this answer is yes, it is necessary. Moreover, in order to achieve the best result, sometimes you have to primer the surface in several layers. This should be done, for example, when the surface of the walls is loose and absorbs moisture well. In this case, the first layer of the primer is almost completely absorbed into the base.

What primer to choose for the apartment?

The modern market offers a huge number of different primers for different surfaces. Choose a primer depending on the type of substrate and its properties. Primer compositions are:

• concentrated;
• in the form of a dry mixture;
• completely ready to use.

The most common composition suitable for processing walls in an apartment before puttying is an acrylic primer. It is universal, therefore it helps to make the finish of the bases of virtually any material with your own hands durable and high-quality.

Acrylic primers can be divided into groups depending on the conditions of their use and purpose:

• universal - suitable for priming any surfaces under any conditions;
• deep penetration primers - are able to penetrate into the base material, smooth it and strengthen the adhesion of the surface to the putty;
• adhesive - this primer contains a quartz admixture, which gives the surface to be treated additional roughness, thereby increasing the adhesion properties of the base.

Indisputable advantages of acrylic compositions are:

• lack of pungent odor;
• drying speed;
• the possibility of high-quality preparation for finishing surfaces with increased porosity.

Tip: when choosing a primer, you need to pay attention to its technical characteristics. It is better to give preference to a composition with a deep penetration level, it is suitable for any purpose.

Primer sequence

When it was decided to do the repairs in the apartment with their own hands, the newly-made masters are concerned about the question: how to prime the walls before puttying? The whole process of priming can be divided into several successive stages.

Preparatory stage

The first priority is the preparation of the walls. They should be cleaned of dirt, dust, old coating, if it began to lag behind the base. Also make sure that the walls are not wet. In the presence of moisture it is better to dry them, since it is proper to prime the walls completely dry.

Primer preparation

The process of preparing the primer is carried out in full accordance with the instructions on the packaging. It is very simple to do it yourself:

• Ready-to-use composition is usually quite simple to mix thoroughly and pour into a convenient container.
• Concentrated primers are diluted in the proportions specified by the instruction.
• The dry mixture should be diluted with water, following the directions on the packaging.

Priming

It is necessary to apply the primer with a thin layer, not wide strips, when priming each subsequent section, stepping a little on the already treated part.

Tip: it is better to use a white or pigmented primer, then all the untreated areas will be clearly visible.

You can cover the walls with soil with a brush or roller. If you need to apply several layers of the composition, you should wait for the complete drying of the previous layer. Approximate primer drying time must be indicated on the package.

Some necessary rules

Carrying out priming work with your own hands, you should remember a few simple rules:

1. Wall surfaces must be clean before processing.
2. If the primer gets on an unsuitable surface, hands or clothing, immediately remove it with a rag dampened with water.
3. It is necessary to try to avoid the formation of smudges.
4. The walls must be primed by protecting the eyes with glasses, hair with a hat, hands with gloves.
5. At the end of the work, immediately wash all the tools: the dried primer mixture is very poorly removed.
