I'm working with 2 sides of a outside corner. One side is new drywall - the other is old existing wall with previous cornerbead being metal.
I decided to remove the corner bead, which on the old wall, still left like 1/32 thickness of mud on the old wall.
Ran No-Coat on it . In trying to keep the corner tight with as minimal taper to the edge possible, it's been a helluva bear trying to finish off the corner to match the exisiting mud so that the edge has square mud edge. I think I'm on my 4th coat already...
I've worked tons with No Coat on new wall and I love the edge it gives.
Just having a bear with working with old/new/matching mud taper/knifing mud to the edge.
Fast forward. I think it's my technique on pulling the knife.
I'm going to try to give it 2 successive thin coats, but instead of pulling the knife vertical, mud the very corneredge and pull the knife from inside of the wall towards the edge. I won't even wipe the edge sharp on the opposing wall ( as it tends to drag mud from the other side). Let it dry and just sand the overhang out, which should be me that sharp edge.
Grrr. It my be faster just to rip the old walls out and then start with fresh ;-). That's the same thing when I had to undercut sheetrock...
