Flexcrete Cementitious Coating 851 Protective Coating - 30kg

Cementitious Coating 851 is designed for internal and external structural waterproofing of concrete and other mineral substrates. Cementitious Coating 851 resists positive and negative pressure under 100m head in water retaining and below ground structures as well as roofs and decks. It provides chloride protection on highway and coastal structures and enhances the durability of reinforced concrete by reinstating effective cover to achieve the specified design life. Cementitious Coating 851 is a two component, thixotropic, cementitious modified polymer coating with high adhesion to both concrete and steel. Cementitious Coating 851 forms a hard, highly alkaline coating with a degree of elasticity which not only protects the concrete, or other substrates, from the effects of aggressive acid gases, moisture and chlorides, but also has greatly enhanced chemical resistance. It is particularly suited for the protection of concrete in sulphate contaminated ground conditions. Can be reinforced with Cemprotec 2000-S tape to accommodate movement around details and over cracks and joints where further movement is expected.
