How to Reglaze Fiberglass Showers


Fiberglass tubs and showers can easily become damaged over time. They can lose the factory finish and they can also crack and chip. Through research you have probably already learned that it is much easier to reglaze the shower instead of replacing it, especially if you tub and shower are one unit. You can hire a professional renovation or repair service to complete this project for you, but it can get quite expensive. You can save a lot of money by reglazing your shower yourself. You can complete this task with the right materials.

Things You'll Need

  • Box cutter
  • Putty knife
  • Flat head screwdriver
  • Fine grit sandpaper
  • #0000 Steel wool
  • TSP cleaner
  • Sponge
  • Paper towels
  • Safety goggles
  • Respirator mask (NIOSH approved)
  • Painter's tape
  • Painter's drop plastic
  • Epoxy paint (designed for tubs and showers)
  • Lacquer thinner or acetone nail polish remover
  • Cotton cloth
  • Bathroom caulk
  • Grout (if needed)
  • Thoroughly clean your shower in the usual manner, making sure that you rinse all cleaners completely. Allow to dry.

  • Remove old caulk and/or grout around the inside of the shower using the screwdriver, putty knife, and/or the box cutter. If one of these tools works better than another, stick with using it. When you are finished, remove the caulking pieces and wipe out the shower with a dry cloth.

  • Scrub the entire shower surface with the steel wool and follow up with the fine grit sand paper. Wipe with a damp cloth or sponge and allow to dry. Look for spots that you may have missed; the goal is to remove all gloss from the surface of the shower so the glaze will adhere.

  • Use the TSP cleaner and a sponge to clean all residue, cleaners, and other invisible traces left on the shower's surface. Rinse thoroughly with clean water and dry completely with paper towels.

  • Apply the painter's tape and painter's drop cloth to areas surrounding the shower where you do not want to paint. This is where you can tape off and cover the fixtures inside the shower as well.

  • Apply the epoxy paint as directed by the manufacturer. You will need to apply the paint in a few light coats. Allow each coat to dry before adding another. You will also need to lightly sand each coat with the fine grit sand paper.

  • Clean an over-spray or excessive runs with a cotton cloth and the acetone nail polish remover.

  • Remove the painter's plastic and tape slowly while the paint is still wet to avoid peeling away parts of the paint away where it overlaps onto the tape. Allow your paint to completely dry for the time recommended on the container directions before using your shower.

Tips & Warnings

  • Don't use fans for ventilation; they can stir up dust and other particles that will stick to your paint.
  • Use the respirator mask for all parts of the project, not just when applying the epoxy paint to your shower.
