This is a very good question...
I think you'll find that:
a) most people will tell you not to do it, and/or if you do, don't seal it
b) some builders/pavers have had bad experiences with the non-stick additives needing to be constantly reapplied or not being effective....this has given the whole topic a "beware of trying it" reputation.
c) some pool owners have somehow found very experienced builders/pavers who know how to do it fine, and report that they are very happy with their sealed stamped concrete and have had no problems other than needing to remember to reseal every few years
The above is based on my research over the last 3 months (talking to numerous contractors and reading online). We're giving sealed stamped concrete a try (using additives/etc) and our pool builder while initially warning us away, says they can comfortably handle the job even when we asked them point blank if it would be easier on everyone if we used a specialist for the decking. This is honestly the only area of our current pool build that we considered farming out. It appears that it can be done but the skills/knowledge may not be transferred too widely.
If you get other or additional info, please post!
