Surface Water Repellents
REC GUARD 1000
REC GUARD 1000 is a solvent-free silane/siloxane concentrate that forms a penetrating, hydrophobic barrier on substrates, inhibiting water absorption while preserving natural appearance. Suitable for neutral and alkaline substrates, it should be kept away from water before use to prevent premature curing.
REC GUARD 7900
REC GUARD 7900 is a breathable, penetrating water repellent that binds and protects concrete, masonry, brick, and stone surfaces. It prevents water intrusion, protecting against spalling, cracking, efflorescence, and freeze-thaw damage, while minimizing salt-related discoloration—ideal for above-ground vertical masonry surfaces.
