Surfblock WB-10

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. ​ Key Features​​​ Non film forming Deeply penetrates porous surfaces, it provides excellent water repellency, while allowing surface to breathe. Superior efflorescence and strong alkali resistance Zero VOC
