Fibreglass Pool Relining Milnerton: Seal Leaks and Cracks for Good

Milnerton pools take a beating. Strong summer wind blows sand and grit into the water, salt air drifts in off the coast, and the sun works on the surface for most of the year. Marbelite and concrete pools in the suburb often start to crack, roughen or lose water long before their owners expect it.

Fibreglass pool relining in Milnerton gives an existing concrete, gunite or marbelite pool a new reinforced fibreglass layer, sealed with a gelcoat finish. You keep the pool you have. You get a smooth, watertight shell back.

Is your Milnerton pool ready for fibreglass pool relining?

Most pool owners call us when one of these shows up:

  • The water level drops faster than evaporation can explain
  • Marbelite feels rough on feet and hands, or has started to flake
  • Hairline cracks appear in the walls or around the steps
  • Algae keeps coming back, even with regular dosing
  • An earlier patch repair has failed again

One of these on its own is not always a reason to reline. Two or three together usually are. We come out, look at the shell and tell you honestly what we see.

Pool leaks in Milnerton: sort the cause before the pool relining

Water loss is the most common complaint we hear from Milnerton. A lining seals the shell, but it does not fix a broken pipe under the paving or a leaking skimmer box. So we find the source first. If the leak is in the plumbing, we repair that before any relining starts.

How we do fibreglass pool relining in Milnerton

The work follows the same order every time, because the preparation decides how long the lining lasts.

  • Drain and inspect. We empty the pool and check the shell properly.
  • Prepare the surface. Old marbelite or concrete is ground and sanded so the new layer can bond.
  • Repair cracks. Every crack is opened up and filled.
  • Prime. A primer goes on before the fibreglass.
  • Lay the fibreglass. Reinforced fibreglass is built up over the whole shell.
  • Gelcoat. A gelcoat finish seals it and gives the final colour.

A typical job takes 5 to 10 working days. Pool size matters, and so does the weather. Wind and rain can push the gelcoat stage out by a day or two, so we plan around the forecast.

What a fibreglass pool lining changes day to day

The finished surface is smooth and non-porous. Algae has far less to grip, so most owners find they brush less and use fewer chemicals than they did with worn marbelite. It is also kinder on children’s feet than a rough plaster finish.

With proper care, a fibreglass lining lasts 15 to 25 years. We guarantee our fibreglass lining and repair work for up to 5 years, depending on the project. You can read the full background on our fibreglass pool relining service.

Fibreglass pool relining or marbelite: which suits your pool?

Marbelite resurfacing is the other option for a concrete pool, and we do both. Fibreglass is usually the better fit where leaks, cracks or constant algae are the problem. Marbelite can make sense on a sound shell where the owner wants a traditional plaster finish. We will tell you which one suits your pool after we have seen it.

Milnerton fibreglass pool relining FAQ

Can fibreglass pool relining go over my old marbelite?

Yes. After draining, grinding, crack repair and priming, fibreglass bonds well over old marbelite or concrete.

Will pool relining stop my Milnerton pool losing water?

It seals the shell. If the leak is in the pipes or skimmer, we repair that separately first.

How long will my pool be out of use for fibreglass pool relining?

Usually 5 to 10 working days, depending on pool size and weather.

What causes black spots in a fibreglass pool?

That is usually osmosis. We grind out the affected area, disinfect it and reline it with new gelcoat.
