My half bath rough in is under the staircase. The original builders put an angled side of the ceiling. I tried hanging a piece of drywall but I'm not super happy with the result. The right side sticks out too much.
Would a prefill layer of (hot?) mud run on each edge fix this? Would normal taping fix this? Or should I take it down and start over? If I need to take it down, would hanging a plywood backer first help?
