Can you paint a fibreglass pool?
Yes, a fibreglass pool can be painted. Two-pack epoxy is the fibreglass pool paint that bonds to the shell. It bonds only after the gelcoat has been abraded until the gloss is gone and then degreased. The gelcoat is smooth and non-porous, so an unprepared surface gives a coating nothing to key into. Painting is also a one-way decision. Once a coating is on the shell, the coating is the pool's finish and the factory gelcoat sits underneath it. The pool is on a repaint cycle from that day, and every later renewal starts by dealing with the paint already there. The colour on a fibreglass pool is sprayed into the mould as gelcoat, before the glass and resin layers are built up behind it. A painted shell can be repainted, but it cannot be returned to its factory finish on site.
MFP Easy builds and installs fibreglass pools across South East Queensland. We do not paint pools and we do not sell pool paint. Painting is the cheapest and the shortest-lived method of fibreglass pool resurfacing, the set of ways a tired interior is renewed rather than replaced.
What kind of paint sticks to a fibreglass pool?
Two-pack epoxy is the paint chemistry that sticks to a fibreglass pool's gelcoat. Paint World describes one Australian system as a high-build gloss epoxy formulated specifically for bare concrete and fibreglass pools. Both components are mixed on the day they are applied.
| Paint type | Bonds to gelcoat | Published life | Recoatable with | Source |
|---|---|---|---|---|
| Two-pack epoxy | Yes, once the gelcoat is abraded and degreased | 7–14 years for one maker's own hi-build epoxy, published on a fibreglass page; 7–10 years and 6–8 years for epoxy pool paint generally | Not published; identify what is already on the pool before buying, since an existing coating is typically epoxy or chlorinated rubber | Hitchins Technologies; PoolPaintOnline; Service.com.au; Bunnings Workshop |
| Chlorinated rubber | Not published; sold as a pool paint | No more than 5–6 years for average, often rubber-based, pool paint | Not published; the same identification applies before recoating | Barrier Reef Pools Perth; Bunnings Workshop |
| Acrylic or general-purpose exterior paint | No pool-immersion bond published for it | Not published | Not published | — |
The Bunnings Workshop community thread on painting a fibreglass pool separates epoxy from chlorinated rubber by applying acetone to a rag and rubbing it over the paint.
The sources disagree about whether paint bonds to gelcoat at all. ecoFINISH is a United States coatings maker that sells a coating as an alternative to pool paint. Its position is that ordinary pool paints were never formulated for the gel coat of a fibreglass shell, and that a surface that smooth makes adhesion very hard to achieve. Australian paint suppliers and pool painters state that two-pack epoxy bonds to fibreglass once the gelcoat is abraded. Read together, the two positions describe different products. ecoFINISH's argument is about traditional pool paint, and it never names two-pack epoxy. The Australian systems are two-pack epoxies specified for fibreglass.
How do you prepare a fibreglass pool before painting it?
Preparing a fibreglass pool for paint takes three moves: the shell is drained, the gelcoat is abraded until the gloss is gone, and the abraded surface is degreased. A fibreglass shell is held in the ground by the water in it, so emptying a fibreglass pool is a structural decision that belongs to the builder rather than to the painter. Gelcoat is smooth and non-porous, so the gloss has to be broken before any paint touches the shell. Degreasing comes after abrasion. A pool interior carries grime, body oils and fats that stop a coating keying even on a roughened surface.
Preparation differs by substrate. AquaGuard 5000 sets out the difference between concrete and fibreglass. Concrete is acid etched and neutralised, or pressure washed, before coating, and concrete and plaster surfaces take a sealer or primer. On fibreglass the equivalent step is abrasion, and the gelcoat is ground back with a coarse disc. Whether a primer then goes onto abraded fibreglass is set by the instructions supplied with the paint system being used.
An empty shell shows what the water was covering. A crack, a chip or a leak found once the water is out is a fibreglass pool repair before anything is painted. A coating over a crack hides the crack and leaves it in the shell. Painting also changes what a gelcoat warranty covers, so the terms should be checked with whoever supplied the shell before the pool is painted.
How do you paint a fibreglass pool, step by step?
Two-pack epoxy is mixed in small batches and rolled or sprayed onto the prepared shell in two or three coats. The coating then cures in an empty pool before the water goes back in. Application is dry-weather work, and epoxy is not applied in mid-day sun.
- Mix the two components. Two-pack epoxy only becomes paint once both parts are mixed together, and the mixed paint has a limited pot life. Leftovers cannot be kept for the next session, so each batch is sized to what can be applied while it is still workable.
- Roll or spray the first coat. Barrier Reef Pools Perth puts first-coat drying at between four and eight hours, in Perth conditions.
- Apply the remaining coats. Hitchins Technologies applies its hi-build epoxy coating in 2-3 coats. PoolPaintOnline, the Australian LUXAPOOL distributor, states a minimum of 2 coats in its coverage guidance.
- Cure the coating in the empty shell. Hitchins Technologies states that its coating requires only 5-7 days curing.
- Refill the pool. Barrier Reef Pools Perth gives the wait before refilling as about a week. Paint World, an Australian paint retailer, gives it as up to ten days.
The two Australian sources do not agree on that last step, and the shell stands empty for whichever window applies. Barrier Reef Pools Perth states two more figures on the same page. A pool can be painted in about two days, and the whole job takes no more than a week. Its week-long refill wait sits on that page too, and whether that week includes the empty-shell cure is never stated. Plan the drain, the cure and the refill as one continuous window.
What colours can a fibreglass pool be painted?
Pool paint is sold in a fixed range of factory colours, mostly blues, greys, sands, greens and black. Paint World lists Nutech NuPool epoxy in 13 standard colours. The listed names include black, Pacific Blue, Beach Sand, Natural Grey, Adriatic Blue, Resort Cream, Pale Blue, Mid Blue, Pond Green, Resort Grey and Blue Bell B41. Colours outside a standard range are made to order, and Paint World puts a minimum four-week lead time on Nutech's made-to-order colours.
A painted colour and a gelcoat colour of the same name do not read the same in water. A paint film is a layer of colour sitting on top of the shell. A gelcoat colour is the moulded surface itself, sprayed into the mould and cured as part of the laminate. Our own gelcoat colour range shows what a factory colour looks like under water. It does not predict how a paint carrying the same name will look.
What does it cost to paint a fibreglass pool?
Service.com.au puts the national average cost to paint a pool at $480 to $650, on a page updated 14 April 2026. Its figure varies with the size of the pool area and the materials needed. That figure does not name a pool type. None of the figures published by Service.com.au, PoolPaintOnline or hipages.com.au prices a two-pack epoxy job on a fibreglass pool as a finished job.
| Item | Published figure | Scope | Source |
|---|---|---|---|
| National average cost to paint a pool | $480 to $650 | National average, pool type not specified, varies with pool area and materials | Service.com.au, page updated 14 April 2026 |
| DIY materials, two-pack epoxy paint and primer | $270 | Materials only, cement pool of around 20–25 m² | Service.com.au, page updated 14 April 2026 |
| DIY materials, rubber paint | $110 | Materials only, cement pool of around 20–25 m² | Service.com.au, page updated 14 April 2026 |
| Epoxy coverage rate | 20–25 m² per 3.5 L kit per coat, minimum of 2 coats recommended | Per kit, per coat | PoolPaintOnline (LUXAPOOL distributor) |
| Kits for an 8 × 4 m pool | Approximately 6 × 3.5 L kits (2 coats) | 8 × 4 m pool | PoolPaintOnline |
| Listed kit prices | Standard colours 3.5 L kits $259.95; designer colours 3.5 L kits $391.35; 1 L kits $113.00 | Listed prices at one retailer on 12 August 2026 | PoolPaintOnline |
The two published cost figures are not measuring the same job. Service.com.au's $270 is materials for a cement pool of around 20 to 25 square metres. PoolPaintOnline's six kits are for an 8 by 4 metre pool at two coats. That count comes from its own rate of 20 to 25 square metres per 3.5 litre kit per coat. Neither source publishes the other's number, so an owner reading both is holding two different jobs rather than one price with a range. Colour choice moves the material cost on its own. PoolPaintOnline listed standard-colour 3.5 litre kits at $259.95, and designer-colour kits of the same size at $391.35, on 12 August 2026.
hipages.com.au prices two related fibreglass jobs on one page. A gel coat repaint and replacement runs $800 to $1,800, varying with size, and a fibreglass resurface runs $2,100 to $7,700. The same source does not state where one job ends and the other begins. Those two bands are best treated as two quotes to ask for by name.
How long does paint last on a fibreglass pool, and why does it come off?
Published service life for two-pack epoxy on a pool runs from about six to about ten years. The published figures spread wider than that once the shorter-life sources are included, and each one is worth reading with its publisher's interest attached.
- Hitchins Technologies, a paint maker, 7 to 14 years. Its hi-build epoxy is described on a fibreglass-specific page as a hard wearing coating lasting 7 to 14 years. That is a maker's claim about its own product, and the top of the range is not a typical figure.
- PoolPaintOnline, the Australian LUXAPOOL distributor, 7 to 10 years. Its published lifespan for epoxy pool paint is 7 to 10 years, given proper surface preparation and maintenance. The figure covers epoxy generally rather than fibreglass alone. The same page recommends epoxy across bare concrete, fibreglass, pebblecrete and marblesheen interiors.
- Service.com.au, a trade-quoting marketplace with no paint to sell, 6 to 8 years. It gives epoxy the longest lifespan of the pool paints, at approximately 6 to 8 years, again for epoxy generally.
- Barrier Reef Pools Perth, an Australian pool builder, 6 to 7 years. It expects between six and seven years from epoxy paint in Perth. Average pool paint, often rubber-based, it puts at no more than five to six years.
- ecoFINISH 2 to 3 years and Mr Fibreglass 1 to 3 years, both selling the alternative to paint. ecoFINISH puts traditional pool paint on a two to three year reapplication cycle. Mr Fibreglass, an Australian resurfacer, gives paint a one to three year life. It sets that against twenty years for fibreglass and ten to fifteen for pebblecrete.
Hitchins Technologies, PoolPaintOnline and Service.com.au overlap at seven to eight years, the only span all three of them publish. The shortest figures come from businesses selling what paint competes with, and the longest from a business selling paint.
Four mechanisms take paint off a fibreglass shell, and ecoFINISH, which sells a coating competing with paint, names all four. Sunlight degrades the film's chemistry and takes the colour out of it inside a season or two. Sanitisers and the chemicals used to correct water balance, chlorine, bromine, pH adjusters and shock, wear the film away. Moisture that works past the film sits against the gel coat, and repeated wetting and drying lifts the coating off the shell from underneath. The film also breaks down at its surface into a white powder. Water chemistry and cleaning practice set how fast those four mechanisms run.
Where do you buy fibreglass pool paint in Australia?
Two-pack epoxy pool paint is bought from coatings suppliers and specialist paint retailers, sold as a kit that holds both components. The systems sold into Australian pools include LUXAPOOL, Poolkote, BG Coatings and Nutech NuPool. PoolPaintOnline distributes LUXAPOOL and Paint World lists Nutech NuPool. Google Shopping AU listed Nutech NuPool Epoxy 4 L at $217 from Epoxy Warehouse on 12 August 2026. The same listing set carried a BG Pool Paint kit at $214 from BG Coatings.
Pool size is converted to kits before anything is ordered. The two inputs are the pool's interior surface area and the coverage one kit gives for one coat, which PoolPaintOnline publishes alongside a worked example for an 8 by 4 metre pool. Coverage is quoted per coat, so the number of coats multiplies the kit count. Kits are sold whole, so an order rounds up to the next kit, and a made-to-order colour has to be placed early enough to clear its lead time before the shell is drained.
One test decides whether a tin on a shelf is the right product: the label has to say two-pack epoxy formulated for pool immersion. A single-pack paint, a general-purpose exterior paint or a rubber-based pool paint is a different product.
Is painting the right call, or should you re-gelcoat?
Painting suits an owner holding the pool for a few more years and working to a small budget. A shell being kept for the long term is better re-gelcoated or coated. Cost per year of service is what separates the two options.
Service.com.au puts the national average cost to paint a pool at $480 to $650. hipages.com.au prices a gel coat repaint and replacement at $800 to $1,800. Its band for a fibreglass resurface is $2,100 to $7,700. The paint figure is the lowest of those three bands. A paint job is bought again every six to ten years: Service.com.au gives 6 to 8 years, and PoolPaintOnline, the Australian LUXAPOOL distributor, gives 7 to 10. None of the named sources publishes a service life for a gel coat repaint or a resurface, so only the paint side of that comparison carries a published repurchase interval.
Two conditions decide whether a pool is painted or re-gelcoated: the state of the gelcoat now, and how long the owner intends to keep the pool. How long the pool is being kept carries the heavier weight, because painting cannot be undone on site.

FAQs
What kind of paint do you use on a fibreglass pool?
Two-pack epoxy, formulated for pool immersion. Epoxy is the chemistry that bonds to fibreglass. It bonds only to a gelcoat that has been abraded until the gloss is gone and then degreased. The systems sold for Australian pools include LUXAPOOL, Poolkote, BG Coatings and Nutech NuPool.
Can you paint directly over fibreglass?
Not over factory gelcoat as it stands. Gelcoat is smooth and non-porous, so a coating has nothing to key into until the surface is abraded and then degreased. Whether a primer goes on after that is set by the instructions supplied with the paint system.
Does Bunnings sell swimming pool paint?
Check the tin rather than the retailer: the product has to be a two-pack epoxy formulated for pool immersion. The Australian pool paint systems, LUXAPOOL, Poolkote, BG Coatings and Nutech NuPool, are sold through coatings suppliers and specialist paint retailers as two-component kits.
How much does it cost to repaint a fibreglass pool?
Service.com.au puts the national average cost to paint a pool at $480 to $650. It puts DIY materials for a cement pool of around 20 to 25 square metres at $270 for two-pack epoxy paint and primer. hipages.com.au prices a gel coat repaint and replacement on a fibreglass pool at $800 to $1,800.
Can you paint fibreglass pool steps?
Yes. A fibreglass pool's steps are moulded into the same shell and carry the same gelcoat as the walls and floor, so the surface being coated is the same surface. They are abraded until the gloss is gone, degreased, and coated with the same two-pack epoxy.
