MASCO Catalog: Construction Liquid and Powder

Read manufacturers' data sheets for complete specifications, installation procedures, and MSDS precautions. Warning: Chronic health effect possible—inhalation of silica dust may cause lung injury/disease (Silicosis). Take appropriate measures to avoid breathing dust. See page 179-180 for more information. 58 MASONS SUPPLY COMPANY Oregon (800) 537-3407 ♦ Washington (800) 537-6216 ♦ www.MASCO.net Clackamas | Eugene | West Eugene | Hillsboro | Medford | Portland | Salem | Ridgefield | Seattle | Tacoma | Woodinville Mascoseal Silane 40% Mascoseal Siloxane 6/12 WB Description : A chemical treatment that helps concrete become repellent to salt, water and other contaminations. Silane 40% is an alkyltrialkoxy silane in mineral spirits. Also available with a fugitive dye. Application : Forms a permanent, chemically bonded layer within the concrete surface. This layer becomes a filter. Salt water and staining substances are repelled while water vapor passes out of the treated surface. This reduces the damaging effects of moisture penetration and the resulting corrosion of reinforcing steel. Reacts within the concrete quickly and exhibits good water repellency in 4 hrs. Sprinkling a few drops of water on the concrete surface is an easy way to check the application. The water drops should “bead” to indicate protection. Applicable Standards : Testing performance evaluations have proven that Silane 40% is superior to olegomeric siloxanes, methacrylates, stearates, siloconates, silicates, urethanes, butadienes, chlorinated rubbers and many other coating systems for water repellency on concrete structures. Coverage : Spray application is recommended. Horizontal: 125 ft²/gal. Vertical: 150 ft²/gal. Rates will vary. Description : A silane/siloxane emulsion penetrating sealer for use on concrete and masonry surfaces. Chemically reacts to the masonry substrate forming a highly water repellent barrier. Provides a layer that becomes a filter for salt, water and staining substances that are repelled while water vapor passes freely out of the treated surface. This reduces the damaging effects of moisture penetration and resulting corrosion of reinforcing steel in concrete. Mascoseal Siloxane VOC is a silane/ siloxane in water emulsion. Has an extremely small molecular structure that allows superior penetration into the substrate for long life. Has good alkalinity resistance. When properly applied, treated surface has a natural appearance. Application : Mascoseal Siloxane is recommended for use on concrete and masonry surfaces—either horizontal or vertical. It is used to protect buildings, bridges and parking garages. Coverage : Clay Brick: 75–100 ft²/gal. Exposed Aggregate: 100–150 ft²/gal. Smooth Concrete: 125–175 ft²/gal. Surface porosity and texture determine the amount of material. The following is a guide for estimating. Always test on actual surfaces for accurate coverage and suitability for that surface.
