Konverter transforms rust into a stable, black chemical compound and forms a film that protects all ferrous surfaces: gates, entrance doors, railings, gutters and anything made of iron. Konverter is widely used in the building sector for the protection from oxidation of the concrete’s reinforcements rods. Spread the product with a brush directly on the rust, leave to dry for at least 12/24 hours than overpaint with any type of paint, even long after application. KONVERTER LIQUID is ready to use and yields about 15 sq.m per litre.
