Silane/Siloxane based hydrophobic impregnant
Protect S 795 is a one component, transparent, penetrating silane/siloxane impregnant. The product reacts chemically with a mineral substrate to form a surface that is repellent to water yet still permeable to water vapour. Protect S 795 protects and preserves the substrate without altering the natural surface texture or colour.
Protect S 795 is recommended for weatherproofing exterior building brickwork, concrete, cement rendered concrete blocks, natural or cast stone etc.
