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. That is why we have primers for absorbent surfaces, non-absorbent surfaces, with tacking effect, with aggregate and even anti-humidity epoxy primers.

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

Below we describe the five types of primers and adhesion promoters that make up the Primacem range.

PRIMACEM FIX

Primacem Plus

Microcement primer with tacking effect

Primacem Fix is a ready-to-use primer for microcement with a tacking effect that favours the adhesion of the existing and the new microcement substrate. It is also especially recommended as a bonding bridge between concrete and mortar.

This water-based primer with great adhesion power on different substrates is highly resistant to alkalis. Primacem Fix adhesion promoter is applied by brush or microfibre roller. One coat is more than enough.

PRIMACEM GRIP

Primacem Grip

Microcement primer with aggregate

Primacem Grip is our microcement primer with aggregate that can be applied on both interior and exterior surfaces. It provides excellent adhesion on smooth or low absorption substrates, so it is highly recommended for application on plaster, tiles, concrete, ceramic or hydraulic tiles in addition to microcement.

This ready-to-use adhesion promoter facilitates anchoring and allows the creation of rough textures. It is applied by brush or roller in a unique coat.
