Interior and exterior wall decoration is one of the most important stages of home renovation. Of course, this operation should be performed correctly. The guarantee of the quality of the finish layer may be the use of a primer. There are several types of this material. Different surfaces use different mixes. In this article, we will deal with all the details of what are deep penetration primers for concrete.
Varieties of materials
All primers existing on the modern market are classified as primers and deep penetration agents. Also on sale is a variety that is a mixture of glue and silica sand. It is called concrete contact.
Primer paints are used for all kinds of smooth, dense, even surfaces for varnishes and paints. Products with quartz sand give a rough surface and are usually used for decorative plaster.
For porous, liquid-absorbing surfaces, a deep penetration primer is used. Concrete contact and primer paints simply create a strong film with certain properties on the walls and floors. Means of deep penetration seep into the material through the pores. Primers of this variety are most often made on the basis of acrylic resins.
Scope of application
Primers of deep penetration are used, like any others, mainly to increase the adhesive qualities of the surface to be coated. Also, these tools allow you to:
Distribute the finish evenly.
Reduce the consumption of final finishing material.
Protect trimmed material from mold or mildew.
Eliminate small differences and surface defects.
Features of deep penetration primers
The funds of this variety go deep into the processed surfaces, primarily due to the fact that the filler used for their manufacture has very fine grain. Its dimensions are ten times smaller than any other types of primers.
Due to the ability of this type of agent to penetrate concrete, the consumption of finishing material is also reduced. Without primer, paint and varnish will fall into the pores, as a result of which several layers will have to be applied. When finishing walls that absorb moisture well with a surface primer, good adhesion is not obtained. As a result, the finish layer begins to lag. This is especially true when using wallpaper on top of putty or plaster. It is necessary to apply a deep penetration primer on concrete or brick in this case. Otherwise, in the future, if it is necessary to replace the wallpaper, the putty will simply depart in pieces.
Deep penetration primers for concrete are made, as already mentioned, based on acrylic. Also, they often include latex. Their advantages, in addition to improving the adhesive properties of the treated surface and reducing the consumption of materials, include:
