Kerakoll Primer A Eco Primer is a solvent-free certified eco-friendly water-based primer for dry, absorbent mineral/cement/gypsum or anhydrite-based substrates. Primer A Eco is a single component surface isolation with very low volatile organic componet emissions, thus sageguarding both operators and the environment.
Primer A Eco develops an isolating, cohesive film which neutralizes the expansive chemical reaction of gypsum- or anhydrite-based substrates in contact with mineral mortars and adhesives. Reduces and regulates the absorption of highly porous substrates.
