  • Surface treatment process for porous solids
    Patent number: 4810533
    Abstract: The present process results in a surface which is impermeable and resistant to the action of chemical substances and heat. Natural stones such as marble, travertine, granite and structural and ornamental works made out of these stones are protected from atmospheric and chemical process of degradation by a novel method of sanding down the surface with an industrial diamond abrasive to open up the pores of these solids; rinsing with water, removing water with a chemical solvent and wiping with a tack cloth to remove microchips. A protective mixture in the form of a moisture-cured polyurethane is then applied to the surface of the stones. The moisture-cured polyurethane acts as a sealant for the pores of the stones and as a chemical polish on the surface of the stones, such sealant being impermeable and resistant to the action of stains produced by chemical substances.
