Surfblock WB-10 is a 10% active water based siloxane/silane water repellent and impregnating agent for porous masonry surfaces such as concrete, block, brick, and unglazed tile. Surfblock WB-10 will penetrate and chemically bond deep within the substrate to provide long lasting protection against deterioration or staining due to water conditions. Surfblock WB-10 will not impair the natural breathing characteristics of treated substrates, nor will it produce a film.
Surfblock WB-10 will help concrete and masonry surfaces to resist common issues such as cracking, efflorescence, spalling, staining, and other damages caused by intrusion of water.
Non film forming
Deeply penetrates porous surfaces, it provides excellent water repellency, while allowing surface to breathe.
Superior efflorescence and strong alkali resistance
