A method for increasing the strength of the bond between a cementitious layer and a tile or substrate layer, including applying a coating of high-silica glaze to the tile, bonding the high-silica glaze to the tile, bonding the high-silica glaze to the cementious layer, and curing the cementitious layer to yield a high-strength bonded tile system. The high-silica glaze further includes silica and flux. The molar ratio of silica to flux is at least about 5 to 1 and the flux further comprises RO and R<SUB>2</SUB>O. The molar ratio of RO to R<SUB>2</SUB>O is at least about 7 to 3. RO is selected from the group including CaO, SrO, BaO, ZnO, FeO, PbO and their combinations and R<SUB>2</SUB>O is selected from the group including Li<SUB>2</SUB>O, Na<SUB>2</SUB>O, K<SUB>2</SUB>O, and their combinations.
