Protectosil 40 S

Silane based water repellent for mineral building materials

Protectosil 40 S

Protectosil® 40 S is a silane based free-flowing, colorless liquid. It is specifically intended for the waterrepellent impregnation of absorbent mineral facade construction materials.

 

Technical Information

Depending on how absorbent the substrate is, experience has shown that concrete requires approx. 0.4 - 0.6 l/m2 and sand-lime brickwork approx. 0.7 l/m2. Porous facade tiles, on the other hand, can require well in excess of 1 l/m2 of Protectosil® 40S. The amount to be applied has to be determined in a trial application.
