Primers and adhesion promoters for micro concrete | Primacem

Primacem is our line of primers and adhesion promoters for micro concrete 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 Micro concrete. 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 micro concrete and other substrates that we manufacture.

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

PRIMACEM FIX

Primer with tacking effect

Primacem Fix is a ready-to-use primer for micro concrete with a tacking effect that favours the adhesion of the existing and the new micro concrete substrate.

A tacking effect primer with high adhesion power and highly recommended as a bonding bridge between new and old concrete and mortar. Water-based product and therefore low sensitivity to water.

A tacking effect primer that is highly resistant to alkalis and adheres easily and quickly to different substrates. It comes in ready-to-use packaging and is applied in one coat by brush or microfibre roller.

PRIMACEM GRIP

Primer with aggregate

Primacem Grip is an aggregate primer that can be applied to both interior and exterior surfaces. An adhesion promoter that is based on synthetic resins in aqueous dispersion.

A primer with aggregate that provides excellent adhesion on smooth or low absorption substrates, generating a rough surface. It is therefore highly recommended for use on plaster, tiles, concrete, ceramic or hydraulic tiles as well as Micro concrete.

A ready-to-use aggregate primer that facilitates anchoring and allows the creation of rough textures. It is applied by brush or roller in one coat.
