Protectosil® 800 is a free-flowing, colorless, solvent-free liquid based on a monomeric alkylalkoxysilane. It is specifically intended for the water-repellent impregnation of mineral construction materials in outdoor areas.
Scope of Application
Because of its unique structure, Protectosil® 800 exhibits superior hydrophobicity on substrates and forms weather- and moisture-resistant bonds to substrates as well.
pure, solvent-free product
watervaporpermeable, colorless impregnation
seals hairline cracks up to 0.3 mm
significantly reduces absorption of water and damaging water-borne salts (e.g. chlorides)
very good penetration
very high alkali resistance
stops alkali/silica reactions in concrete
For the waterproofing of mineral substrates, in particular low-porosity substrates such as:
concrete (road bridges, port installations and all marine concrete structures, concrete facades, exposed aggregate concrete)
Protectosil® 800 is suited for the water repellent impregnation of concrete and other mineral substrates.
Application rate: The amount to be applied depends to a large extent on how absorbent the substrate is. In practice, it has to be determined in a trial impregnation. In the case of concrete at least 150 g/m2 should be applied.
Directions for use: The substrates to be treated should be air-dry and clean (high pressure water cleaning or steam cleaning is recommended) in order to ensure deep penetration of the active ingredient.
