Protect-A-Stone is designed to repel oil, water and stains on a variety of stone surfaces from concrete and limestone to polished granite walls. This product is designed for high-performance building restoration and preservation applications.
DESCRIPTIONThis product is a clear, penetrating sealer with superior surface protection for stone surfaces that creates a barrier to protect against oil, water and stains without altering the appearance of the stone. It is designed to penetrate the surface and cure without the presence silica, expanding and filling cracks and crevices in the material to create a long-lasting repellency to oil, water and waterborne stains. This product utilizes proprietary UV-resistant fluorochemistry that provides a long-lasting protection. It can be applied to surfaces that have previously been treated with silane or siloxane water repellant materials. In independent tests, Protect-A-Stone prevented standing oil from penetrating the surface of concrete for over 2 years. After use, the surface is easily rejuvenated using Presto’s ReJuviClean®.
Can be used on either horizontal or vertical surfaces.
SURFACE PREPARATION Prior to the application of this product, ensure the stone is completely clean and free from all dirt, staining and biological growth using any of Presto’s stone cleaning products. Make sure to thoroughly rinse the material to ensure no product is left behind on the surface prior to sealing. Any cleaning product left on the surface can interfere with the protective coating. APPLCATIONUse a low-pressure sprayer, roller, brush, sponge or lambs wool applicator. Product may also be back rolled. Do not dilute; apply full strength. Apply product to create an even coat on the surface. Allow product to saturate surface. Do not allow product to pool on the surface and dry, or protection will be uneven and a residue may form. Remove excess material with a rag or towel.A second or third coat may be needed for porous, absorbent surfaces or for superior protection. Subsequent coats should be applied in the same manner as the first while the initial application is drying. Never apply a second coat if two coats were not tested and approved prior to use. Protection will begin immediately after sealant dries on the surface. Cure time for maximum water and stain protection is 24-72 hours. Protect surface from contact with water for at least 48 hours. Application rates, concentration, temperature and humidity can impact dry and cure time. Use towels or rags to polish the surface. In many instances, a combination of different stone cleaning products is necessary for various stone surfaces depending on their level and type of staining. Presto offers a complete line of stone cleaning products for all situations, including:
Clean tools and equipment with water. Clean any area that may have overspray with one of the products below:
PROTECTED SURFACE MAINTENANCE INSTRUCTIONSFor light-cleaning and rejuvenating benefits, Presto’s ReJuviClean® can be used. Or for ongoing maintenance of the protected surface, we recommend the use of deionized water. If necessary, use a soft brush to loosen any stubborn soils from the surface. For exterior vertical surfaces on a building that is being properly cleaned using Presto products, we recommend cleaning the surface every 1-2 years for horizontal surfaces, and every 2-3 years for vertical surfaces, in order to maintain a clean appearance and preserve the previous restoration. High pressure is not needed and may damage the surface coating or weaken its performance. This maintenance cleaning is not mandatory to ensure the coating will last as stated in the warranty and is only a suggestion. | Protect-A-Stone is Special Order Only.
