Keim Concretal C Paint

Application

For use on most concrete surfaces and mineral substrates.

Description

KEIM Concretal C is a waterproof sol-silicate paint formulated specifically to give protection to concrete against carbonation and chlorides. Carbonation is a major factor in concrete decay, caused by CO2 from the atmosphere reducing the alkalinity of concrete, which in turn allows the reinforcing steel to become susceptible to attack by water and oxygen, resulting in corrosion of the steel and spalling of the concrete.


Features and benefits:

  • Protects concrete from penetration of CO2 from the air.
  • Protects from corrosion and frost damage due to its elevated water repellence and from external chloride corrosion due to the absence of water movement.
  • Protects against all causes of decay in concrete, including carbonation, weathering, water absorption and chloride corrosion.
