Varieties of materials

All primers that exist in the modern market are classified into primer paints and deep penetration products. Also found in the sale of a variety, a mixture of glue and quartz sand. It is called concrete-contact.

For porous, well absorbing surfaces, a deep penetration primer is used. Concrete-contact and primer paints simply create a strong film on the walls and floors with certain properties. Means of deep penetration seep into the material through the pores. The primers of this variety are produced most often on the basis of acrylic resins.

Scope of application

Deep penetration primers are used, as well as any others, mainly to increase the adhesive qualities of the surface being smeared. Also these tools allow:

Without a primer, the paint and varnish will enter the pores, resulting in several layers. When finishing the well-absorbent walls 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. Apply a primer of deep penetration on concrete or brick in this case it is necessary. Otherwise, in the future, if you need to replace the wallpaper, putty will simply go off pieces.
