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, 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 micro emulsion, a proprietary water repellent and silane/siloxane penetrates and protects the substrate while being highly permeable to water vapor.
NOTE: It is not allowed to send this item through air mode. Surface mode is enabled for the same. Thus, shipping will be done through surface.

How to Apply Okon Penetrating Acrylic Barriers W-2
OKON W-2 can be applied to most porous concrete surfaces that are unsealed, clean (free of dirt, waxes and oils) and sound. New concrete must be cured for 28 days prior to coating. Unsealed: W-2 must be able to penetrate the surface. Test the openness of the substrate by sprinkling with water. If the surface turns dark with the water W-2 can be applied.
OKON W-2 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 (⅓-⅔ gpm) at set a low pressure (500 psi) and a 0.025-0.031” tip. Hold spray tip 12-18 inches from the surface. (Warranty jobs require airless spray application.) 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 ensure 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 or breaks defined with masking tape. Back rolling is recommended to prevent streaking on more dense substrates. W-2 appears milky-white 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-2 may slightly darken the surface and add a slight sheen.
