A low-solids acrylic coating that protects the surface with little to no change in the appearance of the material. This treatment maintains a breathable surface.
The Stone Enhancer series contains two film-forming, acrylic protective coatings for stone surfaces that help to protect against water penetration, erosion, freeze-cracking, water and oil stains, and a variety of other damaging environmental elements. These products help to deter unsightly stains caused by mold and mildew. Surfaces treated with these products can easily be cleaned using deionized water and a mild detergent such as Presto’s Green-Kleen®. Stone Enhancer MD and HD improve stone material in different ways: Stone Enhancer ® MD: Invisible, film-forming, acrylic-based protective treatment leaves an enhanced shine on stone while maintaining a breathable surface Stone Enhancer ® HD: Film-forming, acrylic-based protective treatment leaves an enhanced shine on stone surfaces. This treatment does not allow a breathable surface. Advantages
LimitationsNot suitable for below-grade applications.Horizontal or VerticalCan be used on either horizontal or vertical surfaces. Horizontal surfaces may need reapplication sooner than vertical surfaces.Intended SurfacesUse to seal all types of stone surfaces, including concrete, precast, GFRC, natural stone and masonry.
Surface PreparationComplete all caulking and surrounding construction substrate applications prior to using this product. Newly installed stone or grout must be allowed to cure before application. Protect against personal contact with this and all chemical products. 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 residue left on the surface can interfere with the protective coating. The use of deionized water is required to achieve full product performance. Never apply to a damp or wet surface. Do not apply in below freezing temperatures. Protect any unintended areas. ApplicationUse 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 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.
CleanupClean tools and equipment with mineral spirits. In the event Stone Enhancer is allowed to come in contact with adjacent surfaces, dries and is difficult to remove, use one of the following surface restoration products:
Suggested MaintenanceFor ongoing maintenance of the protected surface, we recommend the use of Green-Kleen diluted 10 to 1 with water, preferably heated deionized water . Apply the diluted product to the surface. Allow to sit for one or two minutes and scrub with a soft bristle if necessary to remove build up. Then gently rinse the surface clean with low pressure. For exterior vertical surfaces, we recommend cleaning the surface every 2-3 years in order to retain 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 recommendation.
