....I just tried out some ideas the other day. I use the same basic materials I use for the fake rocks I've made...
This particular one was not very ambitious, as it is a prototype to learn more about the behavior of the mortars, and was something I just banged out in a weekend (read: not totally finished yet).
I use a styrofoam backing, and the 'thinset' mortar is applied quite a bit thinner than some have talked about (maybe 1/4" or so). There really should be no crumbling if the materials were properly mixed, mine has formed a very hard "skin" and seems pretty tight without any sort of sealer.
