ISOMAT Supergrund – Quartz adhesion primer for smooth surfaces, marble, and natural stone, 20 kg

SUPERGRUND is an adhesion primer made from synthetic resins and quartz sand, designed to improve the bonding strength of adhesives on smooth and non-absorbent surfaces.

It is applied on substrates such as:

• polished natural stone;

• existing ceramic coverings;

• industrial cement-based floors;

• wooden or metallic floors;

• PVC or linoleum flooring;

• anhydrite and magnesite screeds.

The product creates a rough, grippy surface that ensures a strong mechanical bond between the substrate and the subsequent adhesive or mortar layer.

Suitable for indoor applications – including underfloor heating systems – as well as outdoor use, providing high performance, durability, and compatibility with a wide range of construction materials.
