Water Based Silane/Siloxane
10% Active Solids Content
Excellent Water Repellency
Provides Natural Look
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 the intrusion of water.
