I have concrete cantilever coping which hangs over the edge 2" or so. My wan't sealed when the pool was put in and I haven't a clue about concrete whatsoever. Does it need to be sealed? Will it erode away in a few years from all the splashing water and waves when jumping in? If so can anyone recomend an easy sealer to put on? Also I have thought of applying one of those epoxy products? any opinions good or bad on doing so and are there any that you recommend? Thanks all of you for your help. I've only been on this site for 10 days or so but it has become my #1 morning read!
