I am currently getting bids for pool remodel on our old (20+ year) plaster pool. We are going to resurface with PebbleSheen.
One sales rep said they would sandblast the pool surface when drained because our plaster was in really bad shape, spotchy uneven and pitted down to the rebar in places. And chip around the fixtures, etc, and down to the rebar and reseal it. Acid wash and bond coat.
A different pool builder said he would not sandblast (would do all the other things listed above). He did not think sandblast was necessary.
Can anyone tell me if this is a better prep step to indeed sandblast the surface of a very old plaster pool to prep for new Pebblesheen?
Thanks for any advice!
