I need to finish the outside corner above the shower alcove. The shower ceiling is hardibacker and the wall outside the shower is drywall. Where these two meet, what is the proper way to finish it so it's a nice corner? I will just end up painting it.
The walls were easier because I had tile wrapping around the corner so I just taped and thinset those and tiled overtop. Not sure what to do for the ceiling since there won't be any tile.
