Substrates like stone demands special kind of protection. Many chemical substances or even moisture can easily damage the structure and appearance of the stone. Our silane-water based products bonds chemically to the surface of stone creating three-dimensional nano-thin net. Such modified surface into hydro- and oleophobic one prevents other substances to penetrate and damage the stone. Nano-coating is resistant to UV rays, cleaning, chemical biological and physical factors. It protects stone up to 6 years. NANOSTONE does not block the pores, the stone remains vapor permeable.
