Fiberglass pool resurfacing explained
Fiberglass pools have a gelcoat surface that, over time, oxidizes, chalks, and loses color — especially under St. George's UV. Resurfacing means sanding and applying a new gelcoat or modern epoxy-based coating to restore the original look.
When you need it
Chalky-feeling surface, white residue on hands after touching the wall, faded or blotchy color, or visible osmotic blistering all signal it's time.
What's included
Drain, sand and prep the existing surface, apply primer and new gelcoat or epoxy, polish, refill. The process is different from plaster resurfacing — make sure you hire someone who specifically works on fiberglass.
