OKON S-40 is a water-based, oliogomeric siloxane/silane, ready to use, deep penetrating water-repellent. It is a colorless, odorless, non-staining, non-yellowing and nonfilm forming penetrant used to protect concrete or masonry surfaces without altering the appearance or texture of the treated surface. OKON S-40 is breathable, nonflammable and complies with VOC regulations.


It is designed for vertical surfaces, light weight concrete, normal weight concrete block, mortar joints, porous brick, precast, pre-stressed, poured-in-place, exposed aggregate, and air entrained concrete and horizontal slabs, and above grade concrete wearing surfaces.

How to Apply Okon Penetrating Silane Siloxane Sealer S-40


Surface Preparation


OKON S-40 can be applied to porous surfaces that are unsealed, clean (free of dirt, waxes and oils), dry and sound. New concrete must be cured for 21 days prior to coating. Cracks and joints must be sealed prior to application. S-40 must be able to penetrate into the surface. Test the openness of the substrate by sprinkling with water. If the surface turns dark with the water S-40 can be applied. Clean exterior surfaces by pressure washing to remove dust, mildew, sand or other foreign matter. Vacuum and damp-mop interior surfaces. Remove efflorescence with sulfamic or dilute muriatic acid. If acid is used, it must be completely neutralized before applying S-40. Rinse the surface thoroughly after chemical cleaning. Use a degreaser to remove oil or grease stains.


Application


OKON S-40 is ready-to-use and should not be diluted. Agitate before use. Avoid application in windy weather. In hot weather, where possible, lightly spray surface with water to cool the surface to prevent flash drying. S-40 is best applied by low-pressure airless spray but can be applied by garden-type sprayer or small areas can be applied by brush or roller. For airless spray, reduce pressure to 500 psi and use a large tip 0.035 – 0.050” tip. Hold spray tip 12-18 inches from the surface, start at the bottom of the wall and work up with an overlapping horizontal spray pattern to ensure run down of 6 – 8 inches. 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. Uneven application may result in blotchy appearance. Water repellency properties will develop 24 hours to 5 days after application.
