How to Repaint an Enamel Kitchen Sink

The enamel surface on a kitchen sink covers a metal with a ceramic layer. Enamel tends to be durable but over time can start to show signs of wear and tear. Once this happens, your entire kitchen may look worn. If replacing the sink is not in the budget, one cost-effective approach to breathing new life into an enamel sink is to repaint it. Proper prep is the key to a successful paint job for the sink.

Repainting can breathe new life into an old enamel sink.

Step 1

Wash the surface of the sink thoroughly with soapy water. Use a scrub brush on stained areas or stuck-on debris. Rinse well with water to remove soap residue.

Step 2

Wipe down the inside of the sink with a clean, dry towel. Rub denatured alcohol over the surface to evaporate any remaining water.

Step 3

Cover the fixtures with painter's tape (or masking tape). Pry off any caulking around the sink, using the putty knife.

Step 4

Use a porcelain repair product to fill in any chips or cracks in the sink surface. As an alternative, fill in holes with fiberglass putty. Allow the filling to cure, then sand it down until repaired areas are flush with the enamel surface on the sink. Wipe out the inside of the sink with paper towels to remove dust.

Step 5

Apply a bonding primer to the sink with a paint-on or spray product. Follow the instructions on the primer for proper application and let the primer dry thoroughly.

Step 6

Paint the sink with a latex or ceramic paint. Paint one coat and let it dry. If necessary add a second coat.

Step 7

Add a new layer of caulking around the edge of the sink. Follow the instructions on the caulk tube for proper application.
