The standard way of dealing with a cracked ceramic tile is to remove the tile and replace it. This is a lot of work and mess, and it isn't always possible to find the right replacement tile. Another alternative is to fill the cracks with epoxy glue, which dries very hard, and then paint it to match the tile. The painted glue is then coated in polyurethane to protect it. This will not only hide the crack from view, but will prevent moisture from seeping in through the crack.

  1. 1

    Mix your epoxy glue according to the instructions on the container. Carefully pour the mixed epoxy glue over the crack, getting as little of it on the surrounding tile as possible. Use a toothpick to work it down into the crack. The glue should make the surface of the crack flat with the surrounding tile material.

  2. 2

    Gently wipe off the excess glue with a cotton cloth. Make sure not to dig the glue out the crack as you wipe it off.

  3. 3

    Let the glue dry overnight.

  4. 4

    Paint the glue over the crack, using a small artist's brush to apply paint of the same colour as the tile. Paint only on the glue, not on the tile surface. Use a cloth to wipe any excess paint off the tile surface. Let the paint dry overnight.

  5. 5

    Apply a thin layer of polyurethane over the painted glue, using the artist's brush. Let the polyurethane dry for two to three hours, then apply a second coat.

Tips and warnings
