Main highlights

The hydrophobic effect prevents moisture entry from the outside to the inside, but allows the inner moisture to the outside. Bridges hair cracks up to a width of 0.3 mm
Reduces the tendency to soiling the treated surfaces. Prevents the moisture of the building material and thus salt efflorescence as well as moss and algae infestation
Ready-to-use silicone surface hydrophobization
Oligomeric siloxanes in solvents. For outdoor use. Protects against dirt. Can be used on slightly damp surfaces. Forms dirt-repellent surface. UV-resistant
Hydrophobisation of facades and building elements with building materials made of concrete, aerated concrete, fibre cement, brick masonry, sand-lime brick, natural and artificial stones, mineral plasters and mineral paint coatings
High penetration depth UV-resistant
For vertical surfaces only
Dry damp and cracked surfaces, which are then coated with emulsion paints
Can be painted over with standard emulsion paints, odourless, colourless, light colour deepening possible
Can also be used on slightly damp surfaces (not wet rain). Forms a water and dirt-repellent surface
