Surfblock SB-12 400 VOC 5 Gallon

Surfblock SB-12 400 VOC 5 Gallon

Surfblock SB-12 400 VOC is a low VOC, 12% active solvent-based siloxane water repellent and impregnating agent for porous masonry surfaces such as concrete, block, brick, and unglazed tile. Surfblock SB-12 400 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-12 400 VOC will not impair the natural breathing characteristics of treated substrates, nor will it produce a film. Surfblock SB-12 400 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, de-icing chemicals and freeze/thaw exposure. Because of the formulation of Surfblock SB-12 400 VOC, it may be applied to a concrete surface that has been previously coated with many solvent based acrylic sealers.
