Ceresit - a hydrophobizer for the protection of absorbent surfaces CT 9

Solvent-free hydrophobizer for impregnation of absorbent dispersion and mineral substrates.

Features

• alkali resistant
• significantly reducing water absorption
• limiting dirt
• retains high vapor permeability
• deeply penetrating
• does not make the surface glossy
• colorless

Application

The product is used to impregnate external plaster in mineral, roof, mineral paint coatings, clinker masonry, facing brick, sandstone cladding. It can be used on highly alkaline substrates, such as silicate brick walls, new joints, know-cement boards, concrete, fresh plaster, etc. The product can be used to protect building facades, including historic buildings against the ingress of rainwater and aggressive substances contained in the air. It can be used to prevent frost damage, efflorescence, algae and moss growth on facades. The preparation guarantees effective hydrophobic impregnation of substrates, even in the case of hairline cracks up to 0.2 mm wide on their surface.
