Kerakoll Primer A Eco is a certified, eco-friendly, water-based surface isolation for dry, absorbent mineral/cement/gypsum or anhydrite-based substrates, ideal for use in GreenBuilding. Safeguards the health of both operators and the environment. Comes in 5 Litre containers.
Kerakoll Primer A Eco is single-component, solvent-free and with very low volatile organic compound emissions. It binds dust, extends the workability of mineral adhesives and levelling products and is suitable for use on heated substrates.
Kerakoll 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.
Kerakoll Primer A Eco is designed to create a suitable barrier to neutralize the expansive chemical reaction of gypsum and anhydrite-based substrates before laying ceramic tiles with mineral or cement-based adhesives.
