In September 2023, Fibreglaze restored the marblesheen pool in Ferny Grove, Queensland. The existing pool presented with a faded or worn surface and a stained, rough or dated finish, requiring careful assessment and preparation before resurfacing.
The faded or worn surface was prepared for the new lining, and resin-based screeding and filler corrected surface irregularities. A new structural fibreglass laminate and the Fibreglaze Enduratec finishing system were then installed, with the pool completed in Dove Grey Speckle as a smooth, seamless surface.
These photographs follow the work from the pool’s original condition through preparation and repair to the completed finish.
These were the main pool conditions recorded for this project. Select an issue to learn more about its common signs, possible causes and repair considerations.

Fibreglaze recently finished my pool renovation. They were very professional, explaining everything and helping me to select the best options and the most convenient time to do it. The renos they did in is not only good-looking but super practical. The water looks just like I wanted it to, a very clear and bright blue.
They finished the job when they said they would, and clean everything. They gave me instructions on how to restart, and “voila”! I can use my pool every day!
I highly recommend these folks. They’re pro, they make things easy to understand, and they get the job done on time, clean and net.
My first swim in the renovated pool was awesome! Thanks, team!
Answers to common questions about the pool conditions and restoration work shown in this project.
These are common signs that the existing gelcoat is oxidising or wearing away. If the surface is faded, difficult to clean, rough underfoot or no longer holding its colour, resurfacing will restore a smooth, fresh-looking finish.
Pool stain colour alone does not confirm the cause. Brown or rust-coloured marks may involve iron or organic debris; green, grey or black marks can involve algae, copper, manganese or material trapped in a rough surface. Location, texture, recent water changes and the way a small test area responds are more useful than colour by itself. The source also needs attention, such as metals in fill water, corroding equipment, poor circulation or debris, otherwise the stain can return after cleaning.
Oxidised gelcoat commonly looks faded, patchy or chalky and may leave a powdery residue when rubbed. Calcium scale is a mineral deposit added to the surface, so it is more likely to feel raised, crusted or sandpaper-like, particularly around the waterline and high-evaporation areas. Staining and scale can also sit over a worn finish, making visual diagnosis difficult. Check the water balance and have the surface assessed before using aggressive chemicals, because a treatment suited to scale can further damage ageing gelcoat.
Many stains can be treated without resurfacing when the underlying finish is sound and the stain type is correctly identified. Organic, metal and mineral deposits require different treatment approaches, so the safest starting point is water testing and a controlled test on a small area. Resurfacing becomes more relevant when stains are deeply embedded, repeatedly return through a porous surface, or occur with widespread roughness, pitting, peeling or earlier failed repairs. Correcting the stain source remains important after either treatment.
That depends on what remains beneath the faded surface. A cosmetic coating over oxidised, porous or poorly bonded material may only conceal the weak layer and can fail with it. Proper resurfacing removes unsound material, repairs cracks, blisters and soft areas, levels the pool and applies a continuous system suited to permanent immersion. If the existing shell and finish are still sound, the required preparation may be less extensive, but the decision should follow inspection rather than colour fading alone.
Both can feel rough, but they affect the surface differently. Calcium scale adds a raised, chalky or crusted mineral layer, often around the waterline or where evaporation is high. A worn finish has lost material and may feel etched, porous, pitted or uneven across broader areas. Scale can also form over an already deteriorated surface. Water testing, inspection and controlled spot testing help distinguish a removable deposit from surface breakdown before aggressive cleaning or resurfacing is recommended.
