Paint Coming Off Newly Built Pool
by Jane
The pool paint used is coming off in small lumps and there are brown rust spots all over the paint. Can we repaint with an epoxy paint to rectify this? I am the President of a complex here in Fuerteventura and have a hundred apartments to look after and keep the owners happy. Thanking you in anticipation. Jane Thanks for the question Jane I was wondering if the resin is coming through the finish. This is known as Cobalting. The inner layer of the fiberglass is separating. The only way to stop the resin from doing this is to grind it out and fill it with a rubber based filler. This might occur in different areas of the pool. It might be coming from the outer shell and work its way in. Epoxy paints are suitable to paint a shell and some only require a primer and finish coat. But here's the thing... Some pool paint manufacturers say that epoxy paints are not normally used for outdoor pools. They say to use a rubber rubber based paint for pools that have alot of UV sun on them. The brown spots could be rust coming from underneath the concrete and fiberglass. If this is the case, it means that water is somehow getting under the shell and concrete causing rust to form. Painting with a rubber based paint could solve this problem, but with a chlorine pool, eventually the paint will break down over time allowing the water to seep back into any cracks it can find. Paint coming off a freshly painted is pool is normal and will decrease as the pool is used, filtered, and back washed. Chunks of paint and rust is not normal and should be treated. I would call the people back who did the job and explain the situation to them. It should have been done right the first time. If the concrete wasn't sanded and any cracks repaired properly, you're going to have this problem. Here's a link to my pool paint page: Swimming Pool Paint Hope this helps and have a great Summer.
