    Do I need to acid wash the concrete before the new plaster?

    I'm just finishing up my new inground, pool and I was wondering if I should acid wash it or just clean it with a heavy duty concrete cleaner before I have the quartz finish applied on Friday. The pool was shot about 3 months ago and I've always pumped out any water that accumulates when it rains. The shotcrete looks pretty good, it had quite a bit of sand in it from climbing in and out over the past 3 months doing the tiles and stuff, but that's about it. I swept it out this morning. Is a full-on acid wash necessary or can I just pressure wash it with a good concrete cleaner/degreaser?
