We did our patio last May and used Techniseal RG+ Polymeric Jointing Sand. Patio gets filtered sunlight until 4 p.m. I thought Techniseal was one of the better polymeric sands. Techniseals spec sheet says it inhibits weed growth, to me that is like saying stuff is going to grow. Eliminates would be a word to count on and moss and weeds are probably not considered the same.
I am inclined to believe moss will grow anywhere it has optimum conditions. Heck it grows on fairly smooth granite rocks in cottage country.
My guess is it may be controlled with chemicals but not eliminated. I will live with it or use a killing agent but certainly not going to blast out the existing sand and replace it because I am sure it will come back.

When it comes to bare footing on the patio around the pool, I don't like the feel of moss and I particularly don't like how it retains moisture (like dew). I also don't like the look in that application (am okay with it in other settings). Therefore, I want it gone around our pool. Keep in mind that moss requires moisture and a growing medium - IOW, like virtually any plant. A good polymeric does not provide a growing medium and moss just will not grow until the polymeric has failed. Once upon a time, that would take 1-2 years but nowadays a good polymeric should last at least 5 years - during that time, moss absolutely should not grow.

I don't know how you can make the assertion that moss won't grow - they just need a firm surface and tightly locked sand seems like a good enough surface to me. Oh, and they break down the rock below them to sustain themselves. So I guess the sand won't have much nutrients (just silica), but once other things (dust?) gets trapped in the sand, they will have something to feed on and grow!

Also, I found your reference to moss as "they" to be interesting and even a tad anthropomorphic...

A relative has used it and has fuzzy green growth that appears to be some sort of moss: it's only in the area that is permanently shaded by a privacy fence and not the rest of the patio. There is also moss growing on the grass adjacent to the patio stones as well. The area gets wet and doesn't try out.
As for anthropomorphic? From dictionary.com:Seems correct usage to me.
