Keim Concretal W is a sol-silicate protective concrete paint system that offers water repellency, vapour permeability and forms a chemical crystalline bond with the substrate. Keim Concretal W is made using pure inorganic mineral fillers, earth oxide colour pigments and potassium silicate binder.
Keim Concretal W is formulated for In-situ and precast concrete elements and structures, block work, lightweight concrete, asbestos cement and cementitious building boards. Keim Concretal W is used to protect concrete surfaces on exterior façades and interior concrete surfaces with a protective action providing protection from water and weathering by silicification and protection from chlorides.
Keim Concretal W protects concrete from weathering and penetration of liquid water while simultaneously providing very good water vapour diffusion, it prevents water formation within concrete and thus corrosion of reinforcement steel (corrosion protection by keeping concrete dry). Keim Concretal W prevents penetration of chloride salts and other pollutants, it has a matt mineral finish and preserves concrete surface textures.

All loose, flaking and unstable material must be identified and then thoroughly removed, all surfaces must be thoroughly washed down with clean cold water to remove all surface dirt and dust. When all surfaces are clean, sound, wind dry, dust free and free from all surface contaminants, decoration using Keim Mineral
Paints may proceed.
Keim Concretal W should be applied as a two coat system, the first coat to be diluted with up to 30% by weight Keim Concretal Dilution and applied by brush or roller, working well into all surfaces.
