Description
Kerakoll Active Prime Grip is a ready-to-use universal primer designed to improve adhesion between surfaces and finishing materials. It creates a strong, high-grip quartz coating that helps self-levelling products, tile adhesives, plasters, and decorative finishes bond perfectly to both absorbent and non-absorbent substrates.
This water-based primer is quick-drying and eco-friendly, making it ideal for both indoor and outdoor use. It’s perfect for use on concrete, ceramic tiles, marble, gypsum boards, wood, metal, and even old flooring with traces of adhesives or varnish.
Once applied, it forms a thin, durable film that promotes excellent bonding and prevents chemical reactions that can occur between gypsum- or anhydrite-based surfaces and cement-based materials. With its easy roller application and fast drying time, work can continue without long delays.

Strong grip on smooth or difficult surfaces

Suitable for a wide range of materials
