Redoing our fiberglass pool

[DFallOut]

Trying to repaint our fiberglass pool that sat half full for a couple years. Started to scrape bubbles and loose paint, but surface is dimpled as heck. Do I need to strip all the old paint or just the loose stuff? Whats the best method should be looking at? And what's good for patching? Help

Oh, just strip as much as you can or it will just peel again if it's already flaking or dimpled. A sander should do the trick and for patching, you can use marine-grade epoxy. You can do it!

How do you get a smooth, lasting finish on a dimpled fiberglass pool without having to grind down the entire surface?

That dimpling you're seeing is pretty common with old fiberglass. It's often osmotic blistering, where water got through the old paint and is trapped, creating those little bumps. You'll need to strip all the old paint, not just the loose stuff, or the new paint will just lift off in those spots again. The best method for a DIYer is probably a paint stripper formulated for fiberglass pools. Just be sure to follow the instructions carefully and neutralize the surface afterward. As for patching, after you get it all stripped and prepped, any small divots or chips can be filled with a two-part epoxy putty. Once you sand that smooth, you should have a good surface for the new paint. Good luck!

Great advice! Osmotic blistering can be quite frustrating, but removing everything is really the best way to avoid any problems down the line. I completely agree that using epoxy putty is perfect for filling in those divots before you repaint.
