Stone Sealant

With its many textures and varieties from subtle to bold, natural stone can effortlessly pull together any outdoor space. Many types of high-end stone, especially sandstone and travertine, take extra care, because they are particularly porous and easily allow water to penetrate, discolor and deteriorate the surface. To protect your investment and the natural elegance of your space, a NanoSeal high performance coating is highly recommended.

Nanoseal’s nonslip coating dries clear and never yellows to let the stone’s natural beauty shine through. The durable finish stands up to traffic, chlorine, UV and harsh environmental factors and inhibits mold and mildew growth. The unique nanotechnology extends the lifespan of the stone as it repels water from the surface while still allowing water vapor to escape from the stone. If you want to protect your natural stone and keep it looking like new year after year, look to NanoSeal.


Your NanoSeal representative will spend time to understand your specific needs and concerns, and to answer any questions you may have. In all our applications, we only use highly trained technicians who are certified through NanoSeal University to provide you with the best outcome and complete customer satisfaction.

Day 1 – Your certified technician examines and evaluates the area to determine the condition of your natural stone surfaces, including a plan to remove stains, mold, mildew, and grime. Next, the team thoroughly sanitizes and cleans the area, followed by pressure or soft washing and a final rinse of the area if needed to clear away any remaining cleaning solutions. Once it is completely clean, the surface is left to dry for 24 hours.

Day 2 – Prior to the NanoSeal protective application, the certified technician inspects the natural stone to ensure that the surface is dry to the touch. Any sand between the stones that may have been lost during the cleaning process will be replenished. The team then begins the one coat protective application using either the solvent-based or water-based products.


NanoSeal normally dries in sunny areas within 2-3 hours but it requires nearly 24-36 hours for curing. Shaded areas, low temperatures, or higher humidity slow down the drying process. The surface may be kept open to foot traffic in 2-3 hours and to vehicular traffic in 24-36 hours. NanoSeal recommends all sprinkler systems be turned off during this time to allow proper curing.


NanoSeal protects and strengthens your natural stone with a superior breathable waterproof coating that discourages mold and mildew. Periodic washing with plain water to keep the area clean is recommended. Acids, gasoline, hydraulic fluids, and motor oil spills need to be removed from the surface as soon as possible.
