I have a client with a fireplace insert and vaulted ceiling that goes up to 16′ on that side of the living room. They would like to have cultured stone put on the drywall to create a faux stone fireplace (interior) about 6′ wide all the way up to the ceiling.
I’ve been doing some research and can’t find anything regarding using 1/2″ drywall as a substrate under the tarpaper barrier, metal lath, scratch coat.
Anybody have experience with putting cultured stone over drywall or know if its even recomended?
Thanks
Scott

It should be ok, but check your stone supplier.
Most are sellling the metal lath with the building paper alreay on the back of it. That is what you are attching to the walls to support the stone, The drywall won't actually "see" any of the stone, nor should it ever get wet in an interior application. The lath itself is afixed to the walls with fasteners into the studs. At that point the wallboard is nothing more than a backer.
If it were me I'd laminate the drywall with 1/4" WONDERBOARD...rough side out...and thinset or cement it right onto that like this one I did several months ago
Is that a "dry stack"
Is that a "dry stack" stone?
Looks good. I like the idea. I'll use it inside my house, behind each of the free standing wood stoves.
It's real stone and goes up as easy as tile if you're decent at tiling.,,,but it doesn't get grouted. Use either cement or thinset. My supplier has special cement/thinset they recommend but that wall is just cemented over CBU's.
I think it looks just OK. What I don't like is how each section is so square vs puzzle cut.
A puzzle cut design would look much better imo.
