Essup, It's called cultured stone, you will need to put up some 15# tar paper and some lath using roof nails, when you put up scratch coat if you just let it dry a couple hours before you start installing stone it seemed to stick alot better,and what really made the stones stick well was mixing in some thin set with the type n or s morter mix, using rubber gloves and spreading the scratch coat and the morter on the stones by hand and rubbing it in real good was twice or more faster, and stayed on well. Till I did this I would put up 5 stones and one would fall and knock 3 off.
Sounds familiar. I was told to put a small spacer under the screening that is nailed over the 15# paper to give the scratch coat a bit more of a physical bond to the mesh.
