Curious as to what is the recommended way to repair drywall outside corners where, due simply to age, the joint compound has lost adhesion to the corner bead producing a hairline crack that is ever so slightly lifting. Noticing this on almost all beaded corners in this 50 year old home.
I'm getting ready to paint and assuming best practice would be to score out the non-adhering compound (most likely full width of the corner bead itself) and re-compound it? If it were a gap and not simply a hairline crack I'd almost be tempted to let the primer/paint work it's way in and act as a binder.
