We have recently purchased this house 3months ago. The pool we have is hand made from river rocks and its old and has cracks we tried using a sealer before filling it up on any cracks we saw but there is still some that we can't see and I would like to just use a clear sealer to do the whole pool. only thing is that the pool shops in my area don't know what to use or do. I know anything I use won't last for ever over time I'll have to re apply. But any advise would be great. Ill post another thread in the renovate thread with pictures glad to be here I need help as a pool newb
