If your Fibreglass pool is over ten (10) years old it is probably starting to show some signs of surface degradation – both above the water level and below the water level. Fading above the water level will be signs of weathering. This is from the sun constantly beating down on the plastic resin surface of the Fibreglass gel coat. The UV in the sun’s ray attack the plastic and cause it to degrade and fade over time to the point where the surface becomes rougher and starts to attract stains and discolouration.
This is fairly obvious to see the fibreglass surface degrading, but it is under the water level that most of damage is being done, by the very chemicals that keep your pool looking sparkling clean.
What is this I hear you ask? It is the chlorine in the water. Now some people say “I have a salt pool, there is no chlorine” but that is wrong. Salt chlorinators by their very name generate chlorine from the salt that is added to the pool water. Therefore you still have chlorine in the water, it is just generated from the salt instead of being added to the water in the form of tablets or granules or powder.
Have a look at this empty fibreglass pool, you can see above the water level, the colour of the gel coat is in much better condition than below the water level. The chlorine used to keep the pool clean over all the years is an “oxidising agent”. And what it has done, is oxidise the fibreglass gel coated surface to become white and bleached and faded looking. But worst of all is the surface now has a “rough” feeling to the skin, it is no longer smooth like it was when it was new. This means algae and stains cling onto the surface more easily and make the Fibreglass pool surface much harder to keep clean. “What can I do to fix this” I hear you say? The answer is an Aqualux low maintenance pool finish. It is guaranteed and the ideal resurfacing option for a Fibreglass pool. The pool in the photos has been drained in preparation for a smooth to touch, soft and flexible low maintenance finish that will give up to 20 years of hassle free service. You can see how much the Fibreglass surface has worn and discoloured, time for a new look!
