It is the covalent molecular bonding of nano particles in Coval’s products that give them that leading edge

Most other coatings just sit on the surface of the substrate.
Covalent bonding at a molecular level means that Coval’s protective coatings become one with the surface they are applied to and create a superior barrier.

All Coval coatings have the added bonus of providing anti-graffiti protection.


Coval coatings for metal, concrete, wood, stone and circuitry, as well as its anti-graffiti and marine coatings are non-breathable, waterproof coatings. They coat the surface of the substrate completely with a gloss, satin or matte finish (which you specify) and provide a superior barrier against moisture, mold, stains, scratches and graffiti.

Coval coatings all have less than 100g/L VOCs, meet high air-quality standards and contain no known carcinogens under California Prop 65. With Coval coatings there is no need for harsh chemical cleaning and the life of the substrate is extended.


Coval sealers, which can be used on almost any substrate – concrete, wood, stones, tiles and fabric, are breathable, stain and water-repellent . They penetrate the surface of the substrate and are virtually invisible. They repel moisture, stains and mold from within the substrate. Because they are virtually invisible they are ideal for use on historic and protected buildings.

Coval sealers have very low to zero VOCs and contain no known carcinogens under California Prop 65. They harm neither plants nor animals.

Coval sealers are long-lasting and are easy to clean so maintenance costs are reduced and the life of the substrate extended.

Coval Metal Coat substantially reduces surface oxidization preserving integrity and extending durability
