Things You'll Need

  • Epoxy Primer

  • Paintbrushes

  • Bonding Agent

  • Sandpaper

  • Trisodium Phosphate

  • Acrylic Topcoat

  • Paper Towels

  • Palm Sander

Step 1

Combine trisodium phosphate (TSP) and water in the ratios recommended on the TSP packaging. Spray the solution on the front and inside of the sink. Scrub thoroughly with a rag.

Step 2

Sand the sink with a palm sander and medium-grit sandpaper to create a smooth surface for the epoxy primer. Remove sanding dust with a damp cloth.


Step 3

Take the medium grit paper off the sander and replace with fine grit paper. Sand the sink again. Remove the sanding dust with a damp rag.

Step 4

Rub a thin coat of bonding agent onto the sink surface with a paper towel. Allow the bonding agent to dry for five minutes.

Step 5

Apply epoxy primer to the sink with a good-quality paintbrush. Fill the brush with enough paint to coat the brush without dripping. Apply the primer in a thin, even coat, lifting the brush before it begins to make brush lines. Paint the entire sink. Let the first coat dry.


Step 6

Run a piece of fine grit sandpaper under water. Buff out any imperfections in the sink's surface with the sandpaper. Wipe out the sink with a clean towel.

Step 7

Paint the sink with a second coat of epoxy primer, using the same method used to apply the first. Let the second coat dry.

Step 8

Apply acrylic topcoat over the epoxy primer. Brush on two to three thin layers of topcoat. Let each coat dry completely before applying the next one. Give the topcoat a day or two to set properly.


Re-coating the sink is the best way to resurface the porcelain and cover scratches. You can also fix just the scratches by using a patch kit. However, it can be difficult to match the color of an older sink exactly with a patch kit.
