The PB company just started my re-plaster job going from old white plaster to pebble sheen. They are doing a complete chip out in our spa which the old plaster had been chipping off. The subcontractor that is prepping the pool indicated that the main pool doesn't need to be completely chipped out just around the fixtures. The surface in the main pool was still pretty good just started to get discoloration. I thought they would chip out the whole pool so I am concerned at this point. Any comments would be appreciated. Thanks!
