Step 2: PREPARE THE SURFACE FOR PAINTING

In addition to cleaning, you’ll need to rough up the surface of your fiberglass tub so that the paint will adhere properly. Use a medium-grit sanding pad and sand in crosshatch motions along the surface of the tub. Continue sanding until you see all dirt and debris removed from the fiberglass.

Step 3: PRIME THE SURFACE

Apply a primer formulated for plastic surfaces according to the manufacturer’s directions. After allowing ample time to dry, apply two coats of spray paint formulated for plastic surfaces. Let dry completely between each coat.

Step 4: PROTECT THE SURFACE

The polyacrylic transparent acrylic sealer provides the perfect protection for your newly painted fiberglass tub. Use it in place of polyurethane or any other type of spray polyurethane. Be sure to follow the manufacturer’s directions for application and drying time before using your tub.

Now your fiberglass tub can look great for years to come! This project is doable on the weekend, but it does require several supplies and some hard work. If you are uncomfortable with painting, hire someone to do it for you.
