SOLGEL NS is a water repellent treatment for natural stone based on sol-gel technology.
The product contains nanostructured and functionalized silica ideal for the treatment of marble and granite. Once applied it forms a layer of amorphous silica thin, colorless, transparent, compatible with the substrate, water resistant and allowing transpiration. The functionalized component - hydrophobic - is arranged outwards and it prevents the absorption of water and dirt by natural stone.
