Primers and adhesion promoters for microcement | Primacem

Primacem is our line of primers and adhesion promoters for microcement and other materials such as tile, concrete or tiles, among others. These products are essential as they are the first step in the process of applying microcement. Their function is to facilitate the bond between the existing substrate and the new coating.

Our range of primers offers different possibilities and solutions depending on the surface to be coated. A wide range in which we find adhesion promoters that meet the specific needs of each substrate so that the result is optimal.

Thus, we have primers for absorbent surfaces, primers for non-absorbent surfaces, tacking effect primers, aggregate primers, epoxy primers, as well as fillers and smoothing putties.

To ensure optimum consolidation, it is important to follow the steps and recommendations for use of each of the primers and adhesion promoters for microcement and other substrates that we manufacture.

Below we present the complete repertoire of primers and adhesion promoters for microcement that form the Primacem family
