How to Paint the Bathtub

Updated February 21, 2017

Learning how to paint a bathtub can keep it looking good for a few more years--and keep you from having to buy a new one. You can even add decorative paint designs to make your tub look like a designer creation.

Clean the tub with muriatic acid to remove oil and lime deposits. Sand the bathtub with course sand paper, not to remove paint but to create a tooth for the paint to adhere to. Mask the walls of the area to protect them from getting painted.

Cover the faucets and drain with the masking tape, and use a piece of plastic drop cloth to be sure the faucets and drain are covered entirely. Using acrylic paint, apply decorative features to the outside of the tub, if desired. Being careful not to scratch the unprotected acrylic paint.

Open the epoxy paint that came with the kit and quickly apply the paint to the inside wall of the tub, being careful to wear a face mask to prevent inhalation of the fumes. Using a paintbrush, apply to the wall farthest away; load the brush full and apply using a downward stroke, starting at the top of the tub walls.

Completely cover the tub walls and ledge. Allow the paint to dry overnight. When the tub has cured, remove the masking tape. Mix the clear epoxy using 50 percent hardener and 50 percent resin, following the manufacturer's instructions. Apply a thin coat of the clear epoxy to the decorative feature painted in Step 2, making sure to work slowly.

Use the clear epoxy to cover an acrylic painted sink and make the designs in the bathroom match. Clean up the epoxy paint with turpentine, and dispose of leftover paint properly.


Complete all decorative designs before opening the epoxy sealer. Use a self-leveling epoxy.


Be sure to work in a well-ventilated area and to follow the manufacturers' directions.
