Kerakoll Primer A Eco Solvent Free Water-Based Primer 5kg
Extends The Workability Of Mineral Adhesives & Levelling Products
For Internal Use
Solvent-Free
Efficient Dust-Proof Action
Suitable For Underfloor Heating Systems
Size: 5kg
Coverage: 0.15 - 0.25 kg/m²
Certified, eco-friendly, water-based primer for dry, absorbent mineral/cement/gypsum or anhydrite-based substrates, ideal for use in GreenBuilding.
Single-component, solvent-free and with very low volatile organic compound emissions. Safeguards the health of 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.
Creates 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 and/or correction of absorption of highly porous substrates.
Materials:
Gel adhesives, mineral adhesives, dispersed organic mineral adhesives
Cement-based and dispersed adhesives
Mineral finishing, levelling and self-levelling products
Cement or gypsum-based finishing and levelling products and plasters
Substrates:
Gypsum and cement-based plasters
Mineral screeds
