How to repair sink enamel

Updated February 21, 2017

Bathrooms sinks are subject to wear and tear because they are among the most used fixtures in homes. You can repair the sink's enamel inexpensively with very few materials. Pay a visit to your local repair or hardware store's adhesive section to purchase a epoxy. Repainting the sink's enamel can create a cleaner, newer looking appearance in your sink.

Scrub the enamel that is damaged with a sponge doused in soap and water. Rub wet and dry 600-grit sandpaper over the area to remove dirt, rust, and enamel chippings.

Use a small brush to repair enamel with a polyester filler. Gently sand over the filler to smooth over the surface. Apply a primer and allow it to dry completely.

Dispense the epoxy out into a clean plastic or metal container. Do not use glass or foam containers because the epoxy's mixture can heat or melt it. Mix the epoxy well for proper curing. Stir for at least 60 seconds with a clean wooden stick or tongue depressor. Open windows and utilise fans to provide enough ventilation to prevent chemical inhalation.

Apply a thin layer of epoxy to the damaged enamel with an artist's airbrush. Re-coat if necessary. Allow the epoxy to dry for the specified time on the product label. Wait at least 24 hours before using the sink. Do not scrub the repaired area for at least seven days.


Ask a hardware store associate to help you choose the best shades of epoxy needed for your sink. Bring a chipped piece of enamel to determine the best shades for your sink.
