Description
Kerakoll Primer A Eco for Walls and Floors (5kg, 25kg)
- Coverage ≈ 0,15 - 0,25 kg/m2
Certified, eco‑friendly, water‑based primer for dry, absorbent mineral/cement/gypsum or anhydrite‑based substrates.
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.
- For internal use
- Solvent-free
- Efficient dust-proof action
- Extends the workability of mineral adhesives and levelling products
- Suitable for underfloor heating systems
