Newish epoxy paint peeling - concrete pool

The guy is out of business. Do I sand-blast everything, acid etch and coat again?

Maybe not everything. But your new coat is only as sound as what it's attached to -- if you paint over unsound old paint, you will have unsound NEW paint, too.

Sorry. I've used Zeron many times. It's not hard, but it is picky, and many contractors don't 'do' picky. I never had a problem, but I've seen many bad jobs here locally.

moved thread where it should go -- you can post again now. Sorry! Ben
