Why Paint a Sink?

  • Cost-Effective – A fraction of the cost of replacing a sink.

  • Restores Appearance – Covers stains, scratches, and discoloration.

  • Customizable – Choose any color to match your decor.

  • Increases Longevity – A protective coating extends the sink’s lifespan.

Materials Needed

  • Heavy-duty cleaner (degreaser or abrasive cleaner)

  • Sandpaper (400-600 grit)

  • Painter’s tape

  • Drop cloths or plastic sheeting

  • Epoxy-based sink paint or refinishing kit

  • Paintbrush or foam roller

  • Respirator mask and gloves

  • Clear protective topcoat (optional for added durability)

Step-by-Step Instructions

Step 1: Clean the Sink Thoroughly

Before painting, remove any soap scum, dirt, or grease using a heavy-duty cleaner. Rinse well and let it dry completely.

Step 2: Sand the Surface

Lightly sand the sink with 400-600 grit sandpaper to create a rough texture that helps the paint adhere. Wipe away dust with a clean, damp cloth.

Step 3: Protect Surrounding Areas

Use painter’s tape to mask off edges, drains, and faucets. Cover nearby surfaces with plastic sheeting or drop cloths to prevent accidental paint splatters.

Step 4: Apply the Epoxy Paint

  • Use a high-quality epoxy-based paint or sink refinishing kit designed for porcelain, ceramic, or metal.

  • Apply a thin, even coat with a foam roller or brush.

  • Let the first coat dry according to the manufacturer’s instructions, then apply a second coat if needed.

Step 5: Allow Proper Drying and Curing

  • Most sink paints require 24-48 hours to dry before light use.

  • Avoid using harsh cleaners for at least 7 days to allow the paint to fully cure.

  • If desired, apply a clear protective topcoat for added durability.

Maintenance Tips for a Painted Sink

  • Use non-abrasive cleaners to avoid damaging the surface.

  • Avoid scrubbing pads or harsh chemicals that may wear down the finish.

  • Prevent heavy impacts from dropping objects that could chip the paint.

  • Reapply a topcoat every few years to maintain shine and protection.
