Novel environment-friendly method for refurbishing old ceramic tiles

Abstract

The invention relates to a method for refurbishing old wall ceramic tiles. Three materials are adopted for overglazing the old ceramic tiles at normal temperature by four steps, and the steps are base layer treatment, coating of a bottom surface material special for ceramic tiles, coating of a middle layer material special for the ceramic tiles, and coating of a glaze material special for the ceramic tiles. The bottom surface material can be well combined with the surfaces of the ceramic tiles and cannot fall off; the middle layer is a bridge, has the property similar to the bottom layer and the surface layer, and can better bear the bottom layer and the glaze layer, so that the whole surface is more plump; and the glaze layer can achieve the glaze effect similar to the surfaces of the ceramic tiles. The method overcomes the defect that the traditional method for refurbishing and transforming the ceramic tiles has high difficulty and high cost, can maintain the decoration effect of the original ceramic tiles simultaneously, and also can change the colors of the surfaces of the ceramic tiles according to customer requirements. The materials are environment-friendly and nontoxic, and the normal office work is not influenced in the construction process.
