Kerakoll Active Prime Fix 1kg

Kerakoll Active Prime Fix 1kg – Universal Adhesion Primer

Kerakoll Active Prime Fix 1kg is a high-performance adhesion promoter and primer designed to enhance the bond between substrates and subsequent flooring products. Its single-component, water-based formulation delivers excellent penetration and adhesion on both absorbent and non-absorbent surfaces, making it an essential preparatory product before applying self-levelling compounds, cement-based adhesives, renders and finishing plasters.

The primer’s active cross-linking technology develops complete compatibility with a wide range of substrates, ensuring maximum adhesion and reducing the risk of delamination or failure. Its extremely fluid, quick-drying formula consolidates dry or dusty surfaces, regulates absorption on porous substrates and improves the overall workability of levelling and adhesive products applied on top.

Kerakoll Active Prime Fix is suitable for both internal and external use and is a trusted choice for professional tilers and installers preparing substrates for high-performance tile installations, levelling products and mineral-based systems.

Performance & Application

Active Prime Fix’s active cross-linking develops compatibility with both absorbent and non-absorbent substrates, significantly improving adhesion to overlaying products. The fluid formula expands smoothly across surfaces, penetrating and binding dusty or unstable areas for a solid foundation.

Apply with a brush or roller to a clean, dry surface. Allow the primer to dry before applying levelling compounds, adhesives or finishing products. Coverage is approximately 0.1–0.2 kg/m², depending on substrate absorption.
