My 100 year-old house has a plaster on wood lath ceiling that slants up in one corner as it nears the stairwell. This hasn't been a problem (not noticable) but now that I want to add crown molding it will be. It's out as much as an inch over a six foot area.
My thought is to attach wire lath with plaster washers in the worst area and slather a 50-50 mix of Structo-Lite and Mason's Mix (probably two coats), taper it off and finish coat it with drywall mud. I've had success with this method on walls but I've never had a ceiling this bad. Any advise on materials and/or process would be greatly appreciated.
I'd attach some photos but it didn't work earlier.
