Protectosil 20 N

Silane based water repellent for mineral-based building materials

Protectosil 166

For waterproofing of absorbent mineral facade construction materials such as: brickwork, mineral plaster, facades, sand-lime brickwork, ceramic tiles and autoclaved aerated concrete


Technical Information

Waterproofing of facade construction materials with Protectosil® 20 N can contribute significantly to saving heating energy, as the reduction in water absorption also reduces the thermal conductivity of the facade. Application rates depend on how absorbent the substrate is. Experience has shown that the application rate for sand-lime brickwork is approx. 0.7 l/m2 and for porous facade tile significantly more than 1 l/m2 Protectosil® 20 N. The amount to be applied must be determined by a trial application.
