  • Patent number: 5740653
    Abstract: A method for grouting tile comprises applying a protective coat made of self-adhesive, impenetrable, flexible, sheeting material to the top surface and peripheral sides of the tile before grouting, then removing the protective coat after grouting. The protective coat eliminates contact between the grout and the tile surface, thereby eliminating the need for pre-grouting sealer application, tile washing, tile cleaning, and/or acid cleaning of the tile.
