I currently have a a pool that is your tradition gunite with tile around the water line edge. I would like to do a pebble finish with no tile, however the pool contractor is tell me that the pebble finish should never be out of the water. He says that if it is installed out of the water, it fades at a higher rate than under the water line. I have also read online some people have had trouble with stones falling out or degradation above the waterline.
My father has a pebble coated pool with no tile. We live about 30 mins apart, in central FL, although I have significantly more sun on my pool than he does. His pebble finish is 20 or so years old and looks great, I have asked him about these issues and he has said that he has noticed no fading - he has lost a few stones here and there - but it is 1 here or 3 there and nothing you would notice.
Earlier I read this http://www.howibuiltmyownpool.com/mo...ion&phase=tile Which discusses selecting tile or no tile based on scale accumulation and difficulty cleaning. However it does not address the fading and loss of pebbles issue.
I am leaning towards requesting my pool builder install the the pebble finish with no tile, however I get the impression from him this would void the warranty.
