Refurbishing My Homemade Pool 2
So I have to remove the sealer I used to waterproof the pool and make repairs to a few blocks. The little sandblaster works somewhat, but so slowly. Paint remover also works. But nothing cleans these blocks like an angle grinder. It's a nasty job, though. The idea is to remove the sealer, make repairs, and probably plaster the pool, though the beautiful blue sealer I originally used held up for many years. I painted that sealer over the raw blocks with no plaster or primer and had no leaks for at least ten years. Even now the bottom of the pool, where the sealer is intact, holds water. There is a lot of grinding yet to do. Tedious and incredibly dusty work.
