I can see some variation, but it looks like there is a powder on the surface so I think I need to wait until the pool is filled and brushed. There were a couple places that looked like they were burn marks. The guys said that sometimes the flames shift with the wind and cause that so we'll have to see if the water makes a difference. Now, if we could only get the travertine tile replaced. Dit from Cool Pools came out a few months ago and said he had never seen anything like this. But, he hasn't come back since. I called another contractor who is coming tomorrow to take a look and give a quote. He said that it may be due to settling if they didn't pack it well. Now, if I could only find someone to paint the waterfall. What will I ever do when everything is fixed. Oh, maybe swim!!
