Step 1

Sand the tub and shower with a 320-grit sand paper until the surface is dull.

Step 2

Mix one part muriatic acid with five parts water in a plastic bowl. Use a nylon scouring pad to scrub the tub and shower surface with the solution.

Step 3

Rinse the tub and shower completely with water and allow to dry.

Step 4

Use masking tape to cover faucets, hardware and other areas you do not want painted.

Step 5

Apply a layer of epoxy-based primer to the surface of the tub and shower with a spray gun or can. One coat should be sufficient. Allow to dry.

Step 6

Apply an epoxy-based paint to the the entire tub and shower area with a spray gun or can. Allow to dry. If the color is not dark enough, apply a second coat.
