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, tilt-up 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.

How to Apply Okon Penatrating Acrylic Barriers W-1
Clean exterior surfaces by pressure washing to remove dust, sand or other foreign matter. Vacuum and damp-mop interior surfaces. Remove exterior mildew with JOMAX House Cleaner & Mildew Killer or equivalent. Remove efflorescence with suflamic or dilute muriatic acid. Spot cleaning with acid may cause uneven porosity and blotchy appearance.
OKON W-1 is ready-to-use, no thinning is required. Surface can be slightly damp, but not wet at time of application. In hot weather, where possible, lightly spray surface with water to cool the surface to prevent flash drying. It can be applied by garden-type sprayer but is best applied by low-pressure airless spray. Use a small to medium size airless pump at (⅓-⅔ gpm) set a low pressure (500 psi) and a 0.015-0.019” tip. Hold spray tip 12-18 inches from the surface, start at the top of the wall and work down with an overlapping horizontal spray pattern. Make multiple application passes at the top of the wall to insure run down of 3 – 5 inches down the wall. Take special care to saturate mortar joints. Do not stop or interrupt the application in the middle of the wall. Stop application only at expansion joints, walls or breaks defined with masking tape. Back rolling is recommended to prevent streaking on very dense substrates. W-1 appears milkywhite when applied but dries clear. Material that is not absorbed should be back rolled or brushed out to avoid build up. Do not allow puddles, drips or runs to dry on the surface. W-1 may slightly darken the surface and add a slight sheen.
