Can anyone explain best practice for interior application of cultured stone on cement board. Constructing a fireplace surround with steel studs and 1/2 cement board. Can the stone be applied directly to the board? Also, I have heard thinset mortar used, is this proper?

I've always used plywood, felt, wire cloth and a scratch coat, however I quess cement board would be just fine would still use a scratch coat for some tooth,can't see any reason not to use thinset other than cost. Mortar would be just as good and a whole lot cheaper add laxtex if it gives you a warm fuzzy feeling
