6-Pack of 1 gal Zinsser OK911 Clear Okon, W-1 Water-Repellent Sealer Non-Porous Surface

OKON W‐1 Water Repellent Sealer is a proprietary blend of acrylic micro emulsions and a silane‐siloxane solution. The micro‐emulsions penetrate the surface to establish a water repelling barrier in the subsurface of the concrete and masonry. OKON W‐1 helps protect cast concrete, tiltup panels, rough stucco and other comparably dense materials from the damaging effects of water absorption ‐ efflorescence, mold, freeze‐thaw damage, dusting and staining. It can also be used to dustproof unsealed concrete floors or pads. Its unique blend of acrylic micro emulsion, proprietary water repellent and silane/siloxane penetrates and protects the substrate while being highly permeable to water vapor oil‐based polyurethanes.
