I just had my pool resurfaced with a mini Pebble Tec product. I just completed filling it with water this morning. Last night, I turned on the pool light and discovered multiple waves in the bottom of the shallow end. It looks as if it was not troweled right. In the daylight, I did not notice any lumps or waves. I contacted the installer this morning. They replied to keep brushing it everyday for 30 days and it should go away. Does this sound right? I don't see how brushing the bottom will smooth this out. What should I do? Should I push the issue, make them drain and buff it smooth or recomplete the whole job? Or will brushing eventually smooth it out? Thank you for any advice that you can provide!
