  1. Wash your fiberglass shower thoroughly. This will help make sure you get rid of any grime or yellow tint that may have built up.
  2. Next, cover the floor with the plastic you bought. Use masking tape to keep it in place. Be sure to fully cover the floor so the sand dust doesn’t sneak its way under your plastic.
  3. Cover your face with a dust mask or a bandana tied around your nose and mouth to protect your lungs.
  4. Start to sand the fiberglass with the 100-grit sandpaper so it will be ready for the primer. This helps even the surface of the glass as well.
  5. After you finish with the 100-grit, resand the fiberglass with the 200-grit to further even out the surface.
  6. Afterward, wash the surface with acetone cleaner to get rid of all the sand dust. Then wrap the knobs, drains, and faucet with more masking tape to protect it from paint.
  7. Put a coat of spray primer on the sanded fiberglass. Let it dry before sanding it again, gently! Use the 300-grit sandpaper this time. Use a clean cloth to wipe the sand dust off the glass.
  8. Time for a second coat of primer, which you will sand again as you did with the first coat of primer.
  9. Next, you’ll apply 2-3 coats of enamel paint to the glass.  If you use a paint gun make sure you stand at least 10 inches from the glass or wall to prevent paint drips. Make sure you are also painting top down.
  10. Let the paint dry for 24 hours before taking the masking tape off the faucet, drain, and knobs. You can remove the plastic from the ground as well.
