Refinishing an acrylic bathtub is a less expensive option than replacing it. Whether the bathtub is scratched, cracked or just worn, it is possible to repair it with an acrylic repair kit. You can use acrylic repair kits to fix chips, small holes, scratches and small cracks in your bathtub. It will take several hours, but, once complete, your finished surface should be as strong as the original finish. To keep it looking good, use only nonabrasive cleansers to clean it.

Clean the area you will repair. Remove all oil and grease, and make sure that the area is thoroughly cleaned and is completely clean and dry.

Mix the repair filler and hardener, following the instructions on the repair kit. Spread the filler on the area to repair using the spatula. Allow it to dry fully before proceeding further, which can take anywhere from 30 minutes to several hours, depending on both the instructions on the repair kit and the size of the area you're repairing.

Sand the filler to a smooth surface. Use a coarser grit of sandpaper to start, and switch to a finer grain sandpaper to finish the job. Rub until the surface of the repair is at the same level as the surface of the tub. Clean with a soft, clean cloth dampened with the denatured alcohol.

Spray on a light coat of the enamel paint. Allow to dry between coats. Apply additional coats as needed until there is a good finish on the repair. Allow it to dry thoroughly.

Polish the repaired area with the auto polish urethane compound. As you buff the area, work on feathering the edge of the painted area so that the colour of the repair blends in with the rest of the tub.

Allow your repair to cure and harden for 4 days before using your tub.
