Black plaster pool, generally in good conditions with a few few rough areas, mostly on corners of steps but a couple on the side walls.
I've read about some polishing disks, but they show them being used with the pool drained.
Can this be done without draining?
I'd like to do this myself, a little at a time. Even if it is 1 Sq foot per day I can do this while swimming and over time improve the finish.
It is a black plaster pool with a lot of mottling. The look doesn't bother us but the roughness is.
