Surf-Guard SB-20 is a 20% active solvent-based silane water repellent and impregnating agent for porous masonry surfaces such as concrete, block, brick, and unglazed tile. Surf-Guard SB-20 will penetrate and chemically bond deep within the substrate to provide long lasting protection against deterioration or staining due to water conditions. Surf-Guard SB-20 will not impair the natural breathing characteristics of treated substrates, nor will it produce a film. Surf-Guard SB-20 will help concrete and masonry surfaces to resist common issues such as cracking, efflorescence, spalling, staining, and other damages caused by intrusion of water. It also helps protect the surface from damaging effects of water intrusion, acid rain, de-icing chemicals and freeze/thaw exposure.
