Why should not we neglect self-activity?
Everyone who is faced with the need for repair, knows that the priming of walls is one of the required stages of surface preparation. Penetrating into small cracks in the surface, the primer consolidates it, and also allows the application of various compounds in the future, be it paint or varnish. It is this type of repair in several stages that guarantees the durability of the work.
The composition of the self-made primer PVA helps to reduce the cost of buying paint. Due to the fact that the surface becomes smooth and interacts well with new layers, it is not required to paint in several layers.
Those who are just beginning to acquire skills in construction, can doubt the reliability of such methods, they say, when you do it yourself, there are more mistakes. But this is not the case, everything is done extremely simply, and chemical education is not required.
How to prepare a PVA primer?
In order to prepare the primer yourself, you need to take the well-known PVA glue and dilute it in water. Experts do not advise resorting to such a method, if you want to process a large surface, but in small areas it is quite possible to dispense with a glue base.
Diluting the composition in the calculation of 2 parts of water to 1 part of , it is possible to obtain a liquid mass that is fairly easily applied to the surface and leaves an off-white layer. Naturally, the self-prepared primer will not have all the qualities of a professional staff, however, if there is a large stock of glue left after repair, it can be used in the case.
Professional formulations can provide reliable protection from mold formation, glue just helps make the surface more susceptible to the application of new layers of paint and varnish.
As mentioned earlier, it's quite easy to prepare a composition. Do not prepare too much solution, after a long stand, its fastening qualities deteriorate noticeably. It should be understood that the primer with its own hands on quality will always be lower than special compounds.
A few more tricks for the successful repair of
To improve the qualities of the primer, it is always possible to add crushed chalk or a bit of liquid resin to the composition. Adhesive composition is great for processing walls that will be decorated with wallpaper, but the correct preparation of the primer, which is based on PVA, can give a pretty good result.
The main difference of the glue primer is that it does not absorb into the surface, does not fill small cracks and gaps, but simply forms a film. Given the fact that variance gives the best result, you can weigh the pros and cons of the economical option.
Preparation of the composition is best carried out in a warm room, away from balconies and fire. Depending on the required volume of the finished composition, a bucket or any other open container is taken. The glue is gradually poured into it, and water is added to it.
It is very important to perform the mixing, working in parallel with a stick or special blade, the water should quickly dilute the glue, but do not remain on its surface in a separate layer. If the question arises, what to replace the primer, you can always start working with PVA.
The classical proportion is considered to be a variant of 2 parts of water per 1 part of the glue, however, if a person needs to get a more liquid or thicker composition, he can change the value of the shares. The introduction of chalk or resins should be carried out "by eye", gently adding elements to the finished mass.
Do not forget about the rule of constant stirring, as a result, you can get excellent building material, in quality close to professional mixtures sold in specialized stores.
