Fiberglass Gelcoat Refinishing
Fiberglass Pool Resurfacing in Cape Coral
A different process entirely from concrete-pool resurfacing. If your pool is a one-piece molded fiberglass shell, here's what actually applies to you.
An important distinction
Fiberglass pools aren't resurfaced the way gunite pools are
If your pool arrived on-site as a single molded shell rather than being built in place with poured gunite or shotcrete, it's a fiberglass pool — and plaster, quartz, and pebble aren't applied to fiberglass shells directly. Instead, the surface layer is a factory-applied gelcoat, and refinishing it is a different trade and process from concrete pool resurfacing.
This page is here so you land on accurate information regardless of which type of pool you have. If you're not sure which applies to you, the simplest test is the shape: fiberglass pools have smooth, rounded, factory-molded curves and no visible seams; gunite pools can be shaped freely and are finished on-site with troweled or sprayed material.
Quick facts
Common signs a fiberglass surface needs attention
- Chalking — a dull, powdery residue that wipes off on your hand or a swimsuit.
- Fading or yellowing of the original gelcoat color, especially on pools over 10 years old.
- Blistering or small raised bubbles in the surface (osmotic blistering).
- Rough or dull patches where the glossy topcoat has worn away.
What refinishing typically involves
- Draining the pool and thoroughly cleaning and sanding the existing gelcoat.
- Repairing any blisters, cracks, or delamination in the fiberglass laminate underneath.
- Applying a new gelcoat or specialized fiberglass-pool refinishing coating.
- A curing and refill period before the pool is back in normal use.
