Hydrophobic preparation for impregnating façades made of mineral building materials.

Properties

• impregnation for waterproofing facades, in particular for impregnating natural stone and bricks
• invisible after drying
• very good penetration, even into slightly porous materials
• alkali-resistant, making it also suitable for fresh mineral substrates
• protects construction objects against splash and rainwater
• vapor-permeable, frost-resistant
• resistance to the penetration of street salt
