Crommelin Silane Treatment Si is a blend of silane and siloxane technologies which delivers a sealer that penetrates deeply into masonry surfaces and impedes the passage of moisture, providing long-term protection against water penetration. Silane Treatment Si reacts with soluble salts in cementitious surfaces to block capillaries whilst still allowing the substrate to breathe.
