Primacem® Flex is a ready-to-use styrene-butadiene primer in aqueous dispersion, designed as a bonding bridge between new and old mortars and to improve adhesion in microcement and continuous coating applications. It increases the mechanical properties of the substrate, promotes cohesion, and ensures an effective bond between layers without prior dilution.

Frequently asked questions about Primacem
What is a Primacem primer used for?
Primacem primers act as a bonding bridge between the substrate and the microcement or other cementitious coatings, improving adhesion. There is one for each type of substrate, and Primacem Joint is a filler for sealing joints and irregularities before applying the microcement.
Which one do I choose for my surface?
For absorbent substrates such as plaster or plasterboard, Primacem ABS (or Fix). For non-absorbent substrates such as ceramic, marble or porcelain stoneware, Primacem Plus; if they are very smooth, Primacem GRIP adds a rough texture. Primacem Flex works as a bonding bridge between new and old mortars.
Can they be used with any Topciment microcement?
They are compatible with Topciment microcement systems; the descriptions mention Sttandard, Evoluttion, Natture, Industtrial and Efectto Quartz depending on the primer.
Do they need to be diluted or mixed?
No. They are one-component, ready-to-use products: just shake the container before applying.
How are they applied?
On a clean, dry substrate free of dust and grease, apply a thin, even coat with a brush, roller or sprayer, avoiding excess. Primacem Joint, being a filler, is applied with a spatula or trowel.
How long should I wait before applying the microcement?
Primacem Fix, ABS and Plus dry in about 30-60 minutes; Primacem GRIP needs at least 6 hours (and no more than 24). With Primacem Flex, apply the mortar when it reaches the tack stage.
What is the coverage of Primacem Flex?
Approximately 0.1 L/m² per coat; 2 coats are recommended. Actual consumption depends on the substrate and application. Use the calculator above to work out how much you need.
