ISOMAT Supergrund – Quartz adhesion primer for smooth surfaces, marble, and natural stone, 1 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.
