require paint that is used on yachts
Hi @hughsa ,
Welcome to the Bunnings Workshop community. It is wonderful to have you with us.
I wouldn't recommend using a general marine or yacht paint. While these products are designed to withstand harsh marine environments, that doesn't necessarily mean they are suitable for continuous immersion in chlorinated or salt pool water. A purpose-made swimming pool coating would be required.
The products required for repairing and recoating the inside of a concrete swimming pool are quite specialised, so you would generally need to speak with a dedicated pool repair or pool coating supplier for suitable products and advice on the repair process.
I'd recommend having a look through the discussion How to paint a concrete swimming pool?, as there is some good information there that you might find helpful.
Unfortunately, as these are specialised pool repair and coating products, our ability to offer specific product recommendations or detailed advice on the repair process is limited. A dedicated pool repair or coating supplier would be best placed to assist you further.
