Problems With Ceramic Tile

Loose Wall or Counter Tile - Carefully remove the loose tile. Scrape the adhesive from the back of the tile or scrub with steel wool.  Remove the adhesive left in the space on the wall or the counter top.  Use a tile adhesive (available at the hardware store) to re-glue the tile.  Apply a thin even coat to the back of the tile and to the wall or counter surface. For a strong long lasting bond, score the glue covered surfaces of the tile and the wall or counter surface, using a fork.  The roughened surface will ensure a firm hold. Put the tile in place and hold in place for a few minutes exerting light pressure on the wall, or weighing it down with books on a counter top.  When dry, trim any excess adhesive. Use tile grout or mildew resistant grout to fill the joint.
