Our home is an older, fixer upper. We can't afford to rip out all the tile, which was just installed by the previous owner prior to our purchasing the house. We can live it awhile until our budget allows, however, is there any way you know of to rough up ceramic tile that is very slippery when wet? There is high gloss tile on the front porch, in the entry hall and in the bathroom. During the rainy season these areas are lethal!!!! I have slipped several times myself. Is there a way to acid wash or sand blast them to get rid of the high gloss finish and make these areas safe for everyone without ripping out the existing tile???
