Primers and adhesion promoters for microcement | Primacem

Primacem it is our line of primers and adhesion promoters for microcement and other materials such as tiles, concrete or tiles, among others. Fundamental products as they constitute the first step of the microcement application process. Their function is to facilitate the union between the existing support and the new coating.

Our range of primers for microcement that offer different possibilities and solutions depending on the surface that needs to be covered. A wide range in which we find adhesion promoters that adjust to the specific needs of each support for an optimal result.

In this way, we have primers for absorbent surfaces, primers for non-absorbent surfaces, tacking effect primers, aggregate primers, epoxy primers, as well as filler and smoothing putties.

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

Next, we present the complete repertoire of primers and adhesion promoters for microcement that make up the family Primacem.
