I have a ceiling corner above the stairs that needs to be repaired. It was previously drywall on the vertical, and finished ceiling on the horizontal. We caused some damage early on that I covered up and further prevented with a piece of angled aluminium - 2" x 2" at a 90 degree angle that I cut to length and screwed in to cover the angle.
Is there a common way to cover and protect this corner? I'm not against redoing the drywall but if there's an easy way to cover and protect this corner I'd probably go with that.
