I will be having my pool re-plastered due to chipping in the spa and calcium nodules in the pool (thanks to TFP for helping to identify the problem). We are still under warranty and I plan on upgrading the finish to either quartz or pebble (PB doesn't install Pebble Tech), we now have white plaster. Any thoughts on which finish would be better for a re-plaster job, for bonding, and for durability, and maintenance, I have many very tall trees behind my property, so staining has been an issue. I also plan on having this done in September and then closing the pool for the season, so we can use the pool this year...it's only our third season. I wonder if the September date would be a good decision, or if it should be earlier. Any responses would be appreciated, thank you!
