Unfortunately the flagstone on my coping has been deteriorating. I've only owned the pool for a year but it was originally put in in 2007 by previous owner. Some of the pieces are really bad and some of them not so bad, interestingly enough. I'm sure I'll have to replace it shortly but hoping to get a little more life out of it.
I have bought a gallon of the DuPont StoneTech Saltwater Resistant Sealer. Anyone had any experience with this product? Application Tips? Has it/does it work?
