Work With Primers

How and what should the walls be primed before puttying?

Wall repair includes a lot of finishing finishing and preparatory works. This and plastering, and processing putty, and painting the walls or stickers on them wallpaper. All of the listed are attributed to obligatory measures, but for some reason, not all are remembered that a primer should be made before puttying.

And this is in vain, because such treatment of the walls brings a lot of benefits. And no matter what they are built from. So why do we need it and how to do it right with our own hands? Here it is necessary to understand in stages.

For what the walls need to be primed

Primer for puttying of walls means the processing of their entire area until the further works on special compositions are carried out on them. They form on the surface of the thinnest layer in the form of a film, which:

  • increases the adhesive( adherence) properties of walls;
  • instagram story viewer
  • eliminates their looseness and porosity;
  • prevents the destruction of the surface;
  • works as an antiseptic and protects against fungi, rust;
  • does not allow to pick up moisture from the putty layer, so that after drying it will not crumble;
  • promotes the subsequent uniform application of putty and plaster, due to which they are saved, and the finishing decorative materials lie on the surface better and better.

Before the priming of the walls before the puttying, it is necessary to understand with the help of what it is done. After all, as for other repair works, special construction materials are used for this.

Choosing a primer for walls

In the past, simple PVA glue was used for this purpose. He was bred with water and then applied to the wall. Also, the primer for the walls under the putty was made from ordinary paint, which was diluted with a solvent or linseed oil.

Of course, the effect of such compounds was, but not the one that can be achieved now. After all, the industry that produces building materials is actively developing, new technologies are emerging in production, so many types of mixtures for priming surfaces appeared on store shelves. They better lie down, work more efficiently, and use them much easier.

All primer mixtures are classified into categories by many factors. They in their turn include many varieties. For the question of which primer to choose, you can focus on the following table:

Categories Species
Composition Mineral, glyptal, phosphate, acrylic, quartz and others.
By purpose Universal or separately for wood, concrete, metal, plaster, foam concrete.
Based on the penetration level of Deep and shallow.
By the characteristic characteristics of Anticorrosive, moisture-proof, thermal protective, antiseptic.
In place of application Universal or separately for external and internal works.

Regardless of the type, it is better to choose a primer for putty from famous brands. If you use poor-quality products, you can face a lot of problems when repairing walls, in the form of either a swelling of the putty layer, or even worse - with detachment of decorative materials.

The maintenance of priming technology will also be the key to the success of repair and walling works, so it should be treated carefully, especially if this event is planned to be carried out by hand.

Priming process for

walls Primer for puttying surfaces must be started with preparation. At this stage, you may need:

  • removal of the old coating or scraping off the peeling elements from the base;
  • cleaning of the surface from dirt, dust and other particles;
  • degreasing oil stains with special compounds, if any;
  • drying of walls provided that they are wet.

After this you can start the process of preparing the primer mixture for work. This is done quite simply, since all such modern fluids are already sold ready. They simply mix well and pour into a convenient container.

If they were purchased in concentrated form, then before they need to be diluted in accordance with the instructions on the packaging, where the proportion of components must be indicated.

Next, you can start directly applying a primer to the surface of the walls. This is done with uneven uniform movements with the help of a construction roller on an elongated handle in accordance with the principle from top to bottom and vice versa. Vertical stripes of the primer must be overlapped with each other in order to avoid obtaining untreated areas.

When the entire surface is processed, it will take time for it to dry out well. If after that it will be dusty or other defects will be visible on it, then it is desirable to prime it again.

Depending on the initial condition of the wall it happens that it is enough to apply to it one layer of the mixture, but often it requires a priming in 3 steps. At the same time, each time it needs to be allowed to dry out.

You can coat the surface after all the primer layers have dried well. But to delay this event for a long time, too, is not worth it, since dust can again sit on it, flying in the air. As a result, the walls will have to be processed again.

Thus, many have now figured out whether it is necessary to primed the walls before putty, why it is necessary and how important this process is. That is, when repairing the walls of this stage must certainly be remembered. Moreover, this event is quite inexpensive because of the affordable cost of primer mixes.

In addition, this stage of repair can be attributed to simple work that is very easy to do by yourself, even if there are no special skills in this area. A small waste of money and effort on the priming of the walls in the future will help significantly save both money and time, removing the repeated repair of the premises for a long time.
