Surfblock SB 12 – 600 VOC is a 12% active solvent-based siloxane/silane water repellent and impregnating agent for porous masonry surfaces such as concrete, block, brick, and unglazed tile. Surfblock SB 12 – 600 VOC will penetrate and chemically bond deep within the substrate to provide long lasting protection against deterioration or staining due to water conditions. Surfblock SB 12 – 600 VOC will not impair the natural breathing characteristics of treated substrates, nor will it produce a film.
Surfblock SB 12 – 600 VOC 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, deicing chemicals and freeze/thaw exposure.
