A premium quality, chloride-free, low viscosity liquid that penetrates and chemically seals concrete. Produces a hard wearing, non-dusty surface. Suitable for use on garage, warehouse, factory or workshop floors.

Application: Apply a uniform, thin coat onto the surface brushing in well - do not allow to puddle. Once the first coat has cured (normally overnight) apply a second coat. Very porous surfaces may need further applications. After last application leave for 24 hours to allow final coat to dry. Note: Do not use on masonry or coloured concrete. Very dense powder floated floors may not permit effective penetration. Do not wash floor for at least 24 hours after final coat.
