Before beginning the repair work, make sure you switch off the power and water supply. Then, follow one of the techniques mentioned below.
Mix some matching paint with tile filler in a container and dip a cotton swab in it.
Apply it over the cracks and let it air dry, then wipe lightly with a damp cloth. Once done, the crack will be much less visible.
Place a rag over the damaged tile and shatter with a hammer.
Remove the tile chips with a chisel and get rid of the adhesive with a sharp knife.
Clean the edges to clear dust and debris that might get in the way of replacing the tile.
Let it air dry for the duration mentioned on the manufacturer’s instruction manual. Fill the crevices with grout and let it dry for 15 minutes.
Once it dries, wipe the tiles with a damp cloth.
