OKON W-2 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-2 helps protect porous concrete and masonry – medium and normal weight block, rough stucco, non-glazed concrete brick and non-glazed slump block and other comparably porous materials from the damaging effects of water absorption – efflorescence, freeze-thaw damage, dusting and staining. Its unique blend of acrylic microemulsion, a proprietary water repellent and silane/siloxane penetrates
and protects the substrate while being highly permeable to water vapor.

OKON W-2 is recommended for porous surfaces including:
Med. Wt. CMU Rough Stucco Porous Plaster
Normal. Wt. CMU Blasted Concrete Concrete Brick
