StonePro Porous Pro is a premium solvent-based impregnating NanoSealer for quartzite, travertine, limestone, marble, grout, and other porous stone. It provides oil- and water-borne stain protection without changing the color or appearance of the treated surface.

Coverage: Approximately 800–1,000 square feet per gallon, depending on surface porosity and texture.

Application: Start with a clean, dry surface free of debris, waxes, and coatings. Apply an even liberal coat and keep the surface wet for at least 3 minutes, reapplying where it dries. After 5 minutes, wipe the surface completely dry with a clean microfiber cloth. The surface may be used after 20 minutes; full cure and repellency develop in 72 hours.
