Acrylic primer is a characteristic of
. With the help of a primer, it is possible to reduce the absorbency, and also to strengthen the surface layer consisting of hydrophilic porous substrates such as bricks, gypsum, concrete, plasterboard or asbestos-cement slabs. Used in relation to plastered surfaces.
The composition of the product includes a powder mixture, in other words, the acrylic primer of deep penetration consists of graphite, ocher, chalk, spools and zinc vitriol. During production, all components are sieved through a small sieve and ground until a thick mass is obtained. When used, the product is applied to a wooden surface that was previously impregnated with oil.
The composition should be applied with a spatula or brush, it is best to do not more than 4 layers per day. When the last layer finally dries, you can start polishing with emery or pumice with water. Grinding of this primer is simple, an even surface is formed, which is hard enough for further work.
Penetrating and strengthening primer - what's the difference?
Primer universal acrylic can be reinforcing or penetrating. The main difference is in the size of the particles contained in the binder. In the strengthening primer, they are 8-10 times larger than in the penetrating primer. Therefore, the second is easier to enter the pores of the base.
With the use of a strengthening compound, the surface of the surface is glued, and with a deep penetrating base, the base is impregnated only by 10 cm and strengthened throughout the volume. The main thing is the reasonable use of funds. It is impossible to single out any composition, because each of them has its own sphere of application.
When buying a deep penetration primer, pay attention to the solution, it should be a bit muddy. Strengthening is represented by white liquid, which is similar to milk, because solid particles do not allow penetrating into the light. Look at the transparency, it will show which product is better.
Primer AK-070 and other varieties
Primer AK-070 is used for aluminum, titanium, magnesium and stainless steel parts. It can be used for other purposes. Used for internal and external work, when there are conditions of high humidity. Strengthening primer VAK-01-U is designed for fragile substrates, increases the adhesion of water-dispersible materials, promotes a weaker alkaline effect of the plaster.
For interior and exterior use, the alkyd, universal primer VD AK-133 , which is used on metal and wooden surfaces, is characterized by durability and dirt repellent effect. Acrylic primer VD AK-133 can be useful for other purposes, as well as on other surfaces.
Adhesive or acrylic primers increase adhesion between surfaces, are used for substrates that do not have good absorbency. In addition, the acrylic reinforcing primer is important in the treatment of thick-layer dispersion coatings, for example, when the work is associated with decorative plaster.
This mixture is tinted, due to this it can be used as an intermediate painting layer.
To date, consumers have the opportunity to choose suitable primers for their own purposes. To make the right choice, it is important to pay attention to the composition, consistency and transparency of the solution, and we briefly described the popular brands in this article.
