How to :
Fixing a Broken Tile
Step 1
Remove Old Grout
To replace one tile, first dig out the grout around it. Do this with a tool called a grout rake – a utility knife works well too. For a group of tiles, dig out around the section of tiles you’re replacing.
Step 2
Break Up Damaged Tile
Shatter the broken tile into small pieces by hitting it with a hammer and a chisel. Be sure to wear safety glasses because pieces may go flying.
Pry out the pieces and scrape off the grout and adhesive with a chisel or putty knife. Do not disturb the substrate. Remove all the debris and get the surface as clean as possible.
Step 3
Replace With New Tile
Once the tile is all cleaned out, dry-fit the tile first to ensure it is flush with adjacent tiles, then set new tile with recommended mortar.
