After 9 hours recently completely removing a flaky HOUSE paint that the previous homeowner used, I've found many cracks and crevices in my gunite pool. I've determined the coat below that (what's left) is a chlorinated rubber.

Now, I need to patch: two actual cracks (as wide as 3/8"), several deeply pitted areas, one actual HOLE (about 3/4" diameter), and many uneven/pitted areas. I would like to know what to use. The "pool putty" stuff I've used in the past just seems to deteriorate & flake off. I'd like something more durable.

I've read that chlorinated rubbers are "self priming" so I'm hoping to just patch and paint, skipping a primer coat. The method I used to prep the surface was a 2400 PSI pressure wash, and I covered EVERY centimeter of the pool. I'm hoping I can get by without the acid or neutralizer washing.

Thank you!
