I had new plaster put in (May 28) and have had more problems than not. It had anomalies in coloring (cheapest route as I did plain white plaster) and made sure to follow ALL directions (as well as the after plaster care by them) that the pool company gave me to a T. I had rough spots which I understand are trowel issues but now since June it has been showing cracks or "crazing". They have been a pain in my Rear to get them to fix the rough patches/discolorations (no I do not have any vegetation/trees or leaves in my yard or neighbors yards near the pool or any that remains on the bottom as I have a pool person that comes weekly plus I manage cleaning it and water tests myself as well. Any suggestions? I am really getting angry at this point.
