Natural stone can be difficult to protect - Coval extends its life while preserving its natural beauty.

Coval Stone Coat is a high-performance coating designed to protect natural (calcium based) stone against moisture, stains, scratches, etching and mild acids as well as graffiti. It is ideal for use in both home and restaurant kitchens, as well as bathrooms and other high traffic areas.

Coval Stone Coat is completely different from traditional coatings and does not merely sit on the surface. In Coval, molecules cross-link with the natural stone surface to form a covalent bond creating a superior barrier against moisture, stains and etching.

Coval Stone Coat is a cost-effective solution for natural stone protection. It extends the life of the stone while preserving its beauty and greatly reducing the need for expensive refinishing. It can be cleaned with water or a mild cleaner.

Tough, durable, environmentally sound and free of carcinogens

In ASTM Taber Abrasive test D-3363, Coval scored 39.11.  It scored 70-75 on the Rockwell Scale and 7-7.5 on the Mohs Scale.  A diamond is 100 on the Rockwell Scale and 10 on the Mohs.   This means the coatings have a higher resistance to usual wear and tear. With less than 100g/L VOC it outperforms the most stringent air-quality controls in the US. Coval also measures as being carcinogen free as defined by California Prop 65.
