Hi I have a concrete in ground coated with pebblecrete. The pool is about 10 years old. I have been thinking of painting the pool a I don't like the water color from the pebblecrete, also the kids have hurt themselves on the abrasive surface. I was cleaning the pool today, and bought a wire brush to brush the pool surface. So I notice what appears to be dust coming from the surface. I can brush it as many times as I like, and it seems to still come off. Whats happening here. Is the concrete coming off in very fine layers between the pebbles. If so what should I do, or could it be something else,like dead algae between the pebbles.
I have been using powder chlorine for about five years.
I want to install a new Pump/filter/chlorinator, but I would like to sort out this issue first.
Should I just drain it, acid wash and water blast it and paint it.
Any advice is welcome, I have had the pool for 10 years, but only now have the time to do anything with it.
