Lithofin Grout Protector is a ready-to-use, solvent free special impregnator for ceramic, porcelain and quarry tiles. The low viscosity of the product allows it to penetrate well into porous surfaces. Oil and other substances remain on the surface where they can easily be removed before they cause stains. Grout Protector is ideal for protecting absorbent, porous cement based grout especially in kitchens and sanitary areas. The formula is based on a combination of high quality water and oil repellent compounds.
