    Fixing a Cracked Bathroom Sink

  1. 1

    Dry the sink entirely using a hand-held hairdryer. Any dampness or water will not allow the adhesive to fill in the crack and dry properly.

  2. 2

    Use the toothpick to slowly and smoothly fill in the crack using the epoxy adhesive. The toothpick allows for a solid structure to move the wet epoxy through the crack only where it is needed without spreading it along the surface of the sink.

  3. 3

    Wait 24 hours for the epoxy to dry.

  4. 4

    Paint the dried epoxy with appliance paint that matches the colour of your plastic or porcelain sink. A small, thin paintbrush is needed for precision so you do not paint over an area that was not cracked to begin with.

  5. 5

    Let the paint dry.

Tips and warnings

  • If it is not a crack in the sink, but simply a chip or dent, you can use enamel filler to fill in the chipped area. Once it dries you should not be able to tell anything happened.
  • If the crack becomes enlarged are was extremely large to begin with, it is best to replace the entire sink rather than fill in the cracks.
  • Wash hands after using adhesive epoxy and paint.
