OKON S-20 is a water-base, low VOC, high performance ready-to-use, penetrating silane/siloxane water-repellent designed for dense concrete and masonry surfaces. As it penetrates into the surface it reacts with minerals within the substrate and creates a hydrophobic barrier against water intrusion


OKON S-20 can be used on horizontal or vertical surfaces. It protects Cast concrete, tilt-up panels, non-glazed brick, cementitious stucco and other comparably dense materials from the damaging effects of water absorption – efflorescence, freeze-thaw damage, etc. Its unique formulation repels water while being highly permeable to water vapor.

How to Apply Okon Penetrating Silane Siloxane Sealers S-20


Surface Preparartion


Clean: 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. Rinse the surface thoroughly after chemical cleaning. Use a degreaser to remove oil or grease stains. Allow washed surfaces to dry three days prior to coating.


Dry Substrate: Substrate and surface moisture must be less than 17%. In climates where freezing temperatures have existed prior to application, allow adequate time for surfaces to thaw. In hot weather, lightly dampen surfaces with clean fresh water prior to application to prevent a flash cure of material. Do not apply if ambient air or surface temperatures are below 45º or over 90º F.

Sound Substrate: Surface of concrete and mortar joints must be hard and firm - not loose or sandy. The surface is un-sound if it can be scraped or gouged with a flat screw driver. Unsound mortar or deteriorated concrete should be removed and repaired prior to coating. Parapet walls must be capped and backside sealed with a waterproofing membrane. Protect adjacent and underlying surfaces from over spray and rundown.


Application


OKON S-20 is ready-to-use and should not be diluted. Avoid application in windy weather. In hot weather, where possible, lightly spray surface with water to cool the surface to prevent flash drying. S-20 is best applied by low-pressure airless spray but can be applied by gardentype sprayer or small areas can be applied by brush or roller. For airless spray use a small to medium size airless pump (⅓-⅔ gpm) set at low pressure (500 psi) and a large 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 tape.
