Does anyone know best way to grout bubble glass 1x1in. tiles on 1 ft. mesh backing? We've installed all the tile for backsplash behind stove and counter and done several samples of grout. Grout does not sink in deep enough as grout space is less that 1/8 in. and all the colors look really bad. Grout overpowers the beautiful tile. Tile is UBC product called Squared Up. Suggestions??
