Can You Spray Paint Fiberglass? How? 17 Useful FAQs


Yes, it is possible to spray paint fiberglass. However, there are a few things to consider when spraying painting fiberglass:

  1. Surface preparation: It’s important to properly prepare the surface of the fiberglass before applying paint. This may involve sanding, cleaning, and priming the surface to ensure that the paint adheres properly.
  2. Type of paint: Use a paint that is specifically formulated for use on fiberglass or plastic surfaces. Acrylic enamel or urethane paints are good options for fiberglass.
  3. Masking: Mask off any areas that you do not want to paint, such as windows or trim, using masking tape and paper.
  4. Application: Use thin, even coats of paint and allow each coat to dry completely before applying the next. Follow the manufacturer’s instructions for the specific paint you are using, including the recommended drying times and the number of coats.
  5. Finishing: Once the paint is dry, you may want to apply a clear coat to protect the finish and give it a glossy appearance. Use a clear coat that is specifically formulated for use on fiberglass or plastic surfaces.

It’s important to follow the manufacturer’s instructions for the specific paint and clear coat you are using, and to use protective gear, such as gloves and a mask, to minimize your exposure to fumes.
