The pool has been replastered and there are spots where the plaster does not firmly attach to the rock coping. The rocks are rough and I know those guys worked a long time trying to smooth the plaster up to the edges but irregular surfaces are tough.
This makes me nervous as when we bought the house, we found leaks in the pool where the rocks meet the plaster. The pool had leaked since construction and there were really ugly water seepage stains in the driveway in the front of the house, so the water from the pool ran all the way from the back yard to the street. We had a leak detection service ID the leaks and we repaired with epoxy.
I alerted the plastering crew to this and they seemed to avoid the repaired places. But, I would like to go around and re-epoxy any space that seems to have any gap between the new plaster and the rock. I see a lot of spots, and any one of them might leak, IMO, since I am not so sure of the original plastering job and at the rocks they chipped down the old plaster.
The rocks are brown/red and the pool is blue-ish and I don't want to use white epoxy.
Can I tint the epoxy using grout/concrete color?
