I have an in-ground pool which i think is concrete covered with plaster. I just drained the pool so I can paint the bare plaster surface with an epoxy based paint. There is a small leak on the edge of one of the steps (about 1.5 feet below where the water line will be), where water is leaking INTO the pool. There is no crack or obvious point of entry. The water seems to be seeping through the concrete. So far I have ground away the plaster and tried to appily A/B epoxy, but the water just pushes through and finds a new path through the epoxy. What should I do? I'd be happy to provide pictures.
Thanks for any help you can provide,
