How to Replace a Broken Tile

• Working from the center out toward the edges, gently tap out the broken pieces with a hammer and a narrow (3/8- or 1/4-inch) chisel. If you don't have a tile chisel, a cold chisel or even a flat-blade screwdriver will also do the job. Start with the chisel at 90 degrees to the floor, then switch to a 45-degree angle after you penetrate the glaze.

• Once the broken tile is removed, use a wider chisel to clean all the old thinset off the substrate. The same technique applies for all substrates, including mortar, cement backerboard, or plywood.
