How to Replace a Broken Ceramic Floor Tile

There’s no point in completely destroying the existing cracked ceramic floor tile if you do not have one to replace it with.

The chief concern when replacing a broken ceramic floor tile is to not damage the surrounding tiles. To this point it is helpful to apply masking tape over the adjacent ceramic floor tiles. The masking tape provides at least a little protection to the neighboring ceramic tiles.

Next using a power drill or screw gun, and a masonry bit, drill a couple of rows of holes into the broken ceramic tile, near the center of it. Take care to not drill too deep. There is no point in drilling into the subfloor, or even worse through it. You may want to put a small piece of tape on the drill bit as a depth guide mark. Once you have drilled a series of holes into the broken ceramic floor tile use a masonry chisel and a hammer to chip away the ceramic tile between the adjacent holes that you drilled. After effectively connecting the dots with the masonry chisel you can then use either a chisel or flatbar, and a hammer to lift up underneath the broken ceramic floor tile and remove it.

This is where you need to exercise some caution to not damage the adjacent ceramic tiles.

Once you have removed the broken ceramic floor tile, use your chisel and hammer to remove any residual thinset mortar and/or grout from the affected area.

Use a dust pan and broom, or a vacuum cleaner, to pick up all of the broken ceramic floor tile pieces and dust.

Next, apply thinset mortar to the subfloor using a notched trowel. In addition, back butter the replacement ceramic floor tile. Back-buttering involves using your trowel and applying a thin layer of thinset mortar to the back of the ceramic tile. Back-buttering ensures a complete and solid bond to the subfloor. Next, place your replacement ceramic floor tile onto the subfloor and gently push and maneuver it into place relative to the adjacent floor tiles. Make sure to position the tile such that it will have grout lines consistent with the neighboring ceramic floor tiles.

Also make sure the replacement ceramic floor tile is at a height that is consistent with the other neighboring floor tiles. If it is too high, simply remove some of the thinset mortar on the subfloor. If it is too low, add some additional thinset mortar to the subfloor.

Allow the thinset mortar to set up for approximately 24 hours before grouting.

Finally, apply grout around the replacement ceramic floor tile and wipe the excess grout away with a moist sponge. You will probably need to wipe the new floor tile down with the sponge several times over a 30 minute period, so it may be helpful to have a bucket of fresh water nearby.

Once the grout lines have dried your ceramic tile floor should look as good as new.
