Greetings all, I plan to face my front shed wall with real stone about half way up the wall to match my house. Here are the specifics of the materials: -- I have foundation footer already in place -- Wall is currently plywood with roofing paper over it (portion of wall to be faced with stone is 12 x 4) -- Stone is uncut (various shapes) about 3 to 4 inches thick (heavy) My Dilemma ==> Should I create scratch coat (with mesh) against shed wall and mortar stone TO the scratch coat. Or should I leave 1/2 inch gap BETWEEN wall and stone and use brick ties to tie stone to wall?? I see conflicting info out there. I see some that say to use a scratch coat, but at the same time they mention a weeping system. How can you have a gap for a weeping system if you're mortaring stone to the wall? Any help is appreciated.
