Product Description

Keim Concretal C is a waterproof sol silicate based paint formulated for protection against carbonation and chlorides to be used on most concrete surfaces and mineral substrates.

Best Uses

Carbonation is a major factor in concrete decay, caused by CO2 from the atmosphere reducing the alkalinity of concrete. In turn, this allows the reinforcing steel to become susceptible to attack by water and oxygen, resulting in corrosion of the steel and spalling of the concrete.

Keim Concretal C protects concrete from penetration of CO2 from the air, protects from corrosion and frost damage due to its elevated water-repellency, and from external chloride corrosion due to the absence of water movement. Keim Concretal C protects against all causes of decay in concrete, including carbonation, weathering, water absorption and chloride corrosion. Available in a full range of colours.


Two coats are required, with the first coat to be applied by a brush or roller and a final coat to be applied after a minimum of 12 hours undiluted in a like manner.
For the best finish possible, Promain recommend the use of KEIM's Facade Brush for the best application.
