How to Re-porcelain a Sink

The porcelain finish on your sink, like that of an old-fashioned tub, is baked on during the manufacturing process. When that finish becomes worn and dingy, you don't have the option of re-baking it. However, you can revitalize the surface by painting it with a special coating that mimics the look of porcelain. See your refinishing dealer for the proper chemicals and equipment.

Instructions

- 1
  Remove the faucet, faucet handles and all other non-porcelain parts of the sink that you can take off, with your wrench. Put masking tape over all other non-porcelain parts.
- 2
  Spread out plastic tarps around the sink, taping them to the walls and floor. Put on your mask, goggles and gloves.
- 3
  Spread porcelain etching compound over the entire porcelain surface with a paintbrush. Let it work for 10 to 15 minutes, de-glossing porcelain. Rinse the compound off completely.
- 4
  Load the paint sprayer with porcelain primer. Spray it onto the surface a light, thin coat.
- 5
  Let the primer dry for four hours. Spray on a second coat in the same way. Let it dry for 12 hours.
- 6
  Load the paint sprayer with porcelain topcoat. Spray it on in the same way as you did the primer, keeping the coat thin and even.
- 7
  Let the topcoat dry for four to six hours. Spray on a second coat. Let it dry four to six hours. Repeat, spraying four to 10 coats, depending on your desired level of gloss. Let the last layer set 48 hours before putting the re-installing the faucet and other pieces.
