How to Fix Ceramic Tiles
Loose or cracked ceramic tiles not only look bad, they can also cause damage. Tile walls or floors are designed to seal out moisture, and any break in that seal can allows moisture to get behind the tile, which can compromise the whole structure. A loose tile that's intact can be extracted and re-set with new adhesive and grout. A cracked tile should be replaced with a new one. Does this Spark an idea?

1
To remove tiles, use the grout saw to dig out all the grout around those that are loose or damaged. Dig gradually, scraping the blade back and forth over the grout surface.
-
2
Use a hammer and small chisel to tap at the base of the tile -- where it connects to the underlayment -- with the tip of the chisel in the open line. Tap gently, moving the chisel around to different points on the tile to break the adhesive bond without breaking the tile itself. Continue until the tile comes loose.

With the chisel and hammer, chip out any remaining adhesive or mortar left by the tile. Vacuum out the space.

To insert new (or re-set existing) tiles, use a putty knife to "butter" the back of each replacement tile with grout mixed according to package directions. Put each one into position and let them set overnight.

5
Wipe grout over the spaces between the new or re-set tiles and the surrounding tiles, using your grout float to press it down into the lines and simultaneously scrape it off the tile face. Wipe any excess off the tile with a damp sponge.
