Silicate Primers


High-bonding primer coat for lime, silica, and clay plasters for indoor and outdoor. Texture grain: 0.4 mm

Intended use

Ready for use silica primer for lime, silica, and clay plasters. BEECK plaster primer creates a permanent bond on highly- absorbent and also on low-pore, smooth, or organically modified substrates. Simplifies even plaster application with its rugged, slurrying-grainy texture and evens out interfering substrate influences, such as uneven or excessive absorption. Reduces leeching, ring, and stain formation on plaster on critical substrates. Optimized bond to BEECK universal plaster.
