How to paint a fibreglass pool?

[DIYinPink73]

Hi everyone

I have an inground fibreglass pool in need of some TLC. The house is approximately 35 years old - we purchased the house approximately 12 years ago and the pool was looking a little worn out then so I am not sure when it was put but my guess would be that it's around 20 years old.

The pool has developed a couple of small leaks - nothing major - and there are some rust stains in a few spots and there are a couple of spots where the fibreglass is showing through from years of wear and tear. The colour has faded and become a little chalky - basically it just needs a cheeky makeover to bring it back to life.

I am currently repairing the leaks and chips and prepping it for painting. My question is; has anyone painted a fibreglass pool? The information available online is contradictory and less than helpful so I am hoping someone can share their experience and/or knowledge to help me out.

I am a widowed mum of two so my budget is quite limited and I don't have a lot of helpers to call on but my enthusiasm and diy skills are above average (my cooking skills are questionable so I take comfort in the fact that I am good at something).

Please help!!! I am inspired by all of your projects and learn so much from the advice given on here so I look forward to your replies...

Thank you 🙏

Welcome to the Bunnings Workshop community @DIYinPink73. It's a pleasure to have you join us, and many thanks for your question about restoring a fibreglass pool.

I'm not aware of any products suitable for painting your pool as they are quite specialised. I can, however, assist you with some general guidance on your project.

You need to sand back and remove the chalky finish. This might only require a light sand and a thorough scrub down. If a light sand doesn't reveal uncompromised non-chalky paint, then you'll likely need to prime the surface (with a primer specifically for pools) to bond the existing paint and ensure proper adhesion of the new paint.

Once the chalkiness is removed, you must determine what type of paint is already on the fibreglass. You must use the same type of paint to coat over it. You'll typically find it's either epoxy paint or chlorinated rubber. To test your paint, apply some acetone to a rag and rub it over the paint. If it only removes surface oxidation, then you can use epoxy paint, but instead, if the paint becomes sticky, then you'll need to use chlorinated rubber paint.

Remember your PPE when sanding surfaces and using chemical products, including safety glasses, gloves and a dust mask or respirator, depending on the product's safety guidelines.

Please let me know if you have any questions.
