Can a fiberglass pool be replastered?

Not in the usual sense. HomeGuide says the original gelcoat can only be applied in a factory, so the replacement finishes are polymer coatings, pebble or aggregate, tile or paint applied over the sanded gelcoat. A contractor who quotes plain plaster on a fiberglass shell should be asked how they intend to bond it.

How long does a fiberglass pool finish last?

It depends on which finish replaces the gelcoat. HomeGuide publishes 15 to 20-plus years for a pebble finish and 5 to 7 years for paint, and describes the thermoplastic polymer as durable and long-lasting without printing a year count. Ask the manufacturer's warranty length in writing.

Why is a fiberglass pool chalky or faded?

HomeGuide attributes it to the gelcoat degrading from chemical and UV exposure over time. That degradation is cosmetic at first and structural later, which is why the published advice is to refinish before the surface fails rather than after.

Does fiberglass cost more to resurface than concrete?

Slightly, on HomeGuide's table — $7,000 to $15,000 for fiberglass against $6,000 to $15,000 for concrete. Angi and HomeAdvisor read both at about $6,500 per 1,000 square feet. The difference is in the finish options, not the shell.

How much does fiberglass pool resurfacing cost?

Published August 21, 2026

Resurfacing a fiberglass pool costs $7,000 to $15,000, depending on the pool size and finish, per HomeGuide.

Angi and HomeAdvisor both read fiberglass at about $6,500 per 1,000 square feet — the same rate they publish for a concrete pool. Angi adds the line a fiberglass owner most wants: a fresh gelcoat with a painted topcoat, enough to cover minor scratches and dings, runs about $1,000 to $1,200 on its figures. That is the repair-scale option; the four-figure-to-five-figure band is the full refinish.

This page is general information, not professional advice. Prices move with your pool's size, shape, condition and region, and the only number that counts is a written quote from a pool contractor who has drained and inspected yours.

Why a fiberglass pool cannot just get new gelcoat

HomeGuide's explanation is the one to keep. Fiberglass shells leave the factory with a tough gelcoat that slowly degrades under chemicals and sun. That gelcoat can only be applied in a factory, so when it is done, other finishes have to take its place: the old gelcoat is sanded and prepped, and a new surface is applied over it. The two finishes HomeGuide names as the common choices are thermoplastic polymer coatings such as EcoFinish and pebble finishes such as Pebble Tec.

Fiberglass pool resurfacing cost by finish

Finish	Per square foot	Who publishes it
Epoxy paint	$1 – $2	Angi, HomeGuide
Aggregate (quartz, pebble, glass bead)	$5 – $7	Angi
Pebble	$7 – $15	HomeGuide
Thermoplastic polymer (EcoFinish)	$10 – $15	HomeGuide
Tile	$4 – $30	Angi

HomeGuide's published per-square-foot prices for the finishes it names as suited to fiberglass, plus the paint option Angi lists.

HomeGuide prices an EcoFinish coating at $10,000 to $15,000 for a medium-sized pool and describes it as a sprayed thermoplastic that resists chipping, peeling and cracking on both fiberglass and concrete. Angi's read on aggregate for fiberglass is $5 to $7 per square foot, which is why a quote for a pebble or quartz finish can come in under the polymer number.

Gelcoat repair versus full resurfacing

HomeGuide's repair guide prices a gelcoat application for dings, scratches and cracks at $300 to $400, with repainting the surface afterward extra. Angi's gelcoat-plus-topcoat figure of $1,000 to $1,200 is the next step up. If the damage is cosmetic and local, one of those is the honest fix. If the surface is chalking, crazing or blistering across the whole shell, the full refinish at $7,000 to $15,000 on HomeGuide's band is the job.

Ask the bidder whether they are quoting a gelcoat touch-up or a full refinish. The two differ by an order of magnitude and both get called resurfacing.
