We live in Arizona, and have just completely remodeled our pool and spa. We chose quartz plaster. They plastered the whole pool and spa and then imediately started to fill. Once it was full, they added acid, and we brushed 3-4 times a day for about 10 days. It all looks great, and the plaster is smooth, with the quartz looking great. However, the spa is rough. You can feel the quartz coming through it and it feels completely different than the pool. I think they put too much acid in the spa. Now the pool company says they will come out and sand it??? Does this sound right? Just wondering, as we have put a lot of money into this, and we really want to have it done right. Thanks!
