How to Repair a Fiberglass Pool


Swimming pools are a luxury item enjoyed by people all over America. One of the most popular and least expensive building materials for pools is fiberglass. These pools are quick to install, but they are also somewhat fragile. In the event your fiberglass pool becomes damaged, you can repair it yourself with just a few tools and a little know-how.

Things You'll Need

  • Clean rags
  • Rough sandpaper
  • Scissors
  • Fiberglass resin and cloth
  • Disposable paintbrush
  • 3-inch putty knife
  • Spray paint (same color as your pool)
  • Rubber gloves
  • Safety glasses
  • Respirator
  • Drain your pool and dry the work area with clean cloths. Sand the damaged area to smooth the surface and remove any paint.

  • Cut the fiberglass cloth with scissors so that it overlaps the damaged area by at least 3 inches on each side.

  • Mix the fiberglass resin according to the manufacturer's instructions. Apply the resin to an area at least 3 inches wider than the damaged area. Press the fiberglass cloth to the wet resin, and smooth it with a putty knife.

  • Apply a thick coat of resin gently to the entire patch. Allow the fiberglass to dry and harden overnight.

  • Sand the fiberglass to smooth and contour it into the existing shape of the pool. Wipe off any residue with a clean rag.

  • Spray the patch with paint. Hold the spray can 6 to 8 inches away, and paint in a side-to-side sweeping motion. Allow the paint to dry completely.

Tips & Warnings

  • Fiberglass and spray paint pose inhalation hazards. Read and follow all of the manufacturer's instructions before using any chemicals. Always wear appropriate safety equipment such as a respirator, safety glasses and rubber gloves when using chemicals. Always work with chemicals outdoors or in a well-ventilated area.
