Costar Dustproofer
Costar Dust-proofer is a ready to use low viscosity dustproofing liquid for concrete floors, paths and driveways. It is suitable for used both internally and externally. It penetrates concrete surface and chemically reacts within the concrete surface, producing extremely hard and dense calcium silicate hydrate (CSH) in the concrete pores thus creating a concrete that is more durable, easier to clean, and more resistant to damage from water.
