Pro Porous Surfaces Impregnating Sealer for superior protection of travertine, limestone, grout, and other porous stone and masonry surfaces. Stone Pro Impregnator Features: Stone Pro Porous Pro is a professional-grade impregnating sealer specifically formulated for highly porous natural stone and masonry surfaces. Using advanced fluoropolymer and nano technology, it penetrates deep into the substrate to provide long-lasting protection against water- and oil-based staining while maintaining the natural appearance of the surface. It is particularly effective on travertine, limestone, marble, grout, brick, slate, and other porous materials. Unlike topical coatings that create a film on the surface, Porous Pro penetrates below the surface, allowing the stone to breathe while helping prevent staining and moisture intrusion. Key Features & Benefits Advanced Nano Protection Porous Pro utilizes advanced fluoropolymer and nano technology to provide exceptional stain resistance and oil and water repellency. Designed for Porous Stone Its larger molecular structure is engineered specifically for highly absorbent materials such as travertine, limestone, grout, brick, slate, and masonry surfaces that can be difficult to protect with standard sealers. Natural Appearance Preservation The sealer will not yellow, create a surface coating, or significantly alter the natural look of the stone. Interior & Exterior Applications Suitable for both indoor and outdoor use, making it ideal for countertops, floors, showers, patios, pool surrounds, facades, and masonry installations. Food Preparation Surface Safe When used as directed, Porous Pro is suitable for kitchens and food preparation areas. Recommended Surfaces Porous Pro is commonly used on: Travertine Limestone Marble Slate Brick Grout Masonry Concrete Porous natural stone surfaces Common Applications Travertine Floors & Patios Provides deep penetrating protection against moisture, dirt, food spills, and environmental contaminants while preserving the natural beauty of travertine. Limestone Installations Helps reduce staining and water absorption on interior and exterior limestone surfaces. Grout & Masonry Penetrates porous grout joints, brick, and masonry materials to help prevent staining while allowing vapor transmission. Outdoor Hardscape Projects Suitable for patios, pool decks, walkways, retaining walls, and decorative masonry exposed to weather and moisture. Application Instructions Surface Preparation Surface must be clean and dry. Remove waxes, coatings, dirt, and contaminants before application. Test in a small inconspicuous area prior to full application. Application Apply evenly with a low-pressure sprayer, lambswool applicator, roller, or cloth. Allow material to penetrate the surface. Two coats are recommended for maximum performance on highly porous materials. Remove excess sealer before it dries on the surface. Coverage Rates Approximate coverage: 200 to 1,000 square feet per gallon depending on substrate porosity and surface texture. More porous materials will require additional product and multiple coats. Available Sizes Gallon 5 Gallon 55 Gallon Availability may vary by distributor. Shelf Life & Storage Store in original tightly sealed container. Protect from excessive heat and ignition sources. Store in a cool, dry location. Keep container closed when not in use. Frequently Asked Questions What is Stone Pro Porous Pro used for?
