Bullnose wall corner bead? is coming loose
My house has bullnose outside drywall corners that apparently are formed using a metal bead (at least I think that's what it's called). In several places, the edges of the bead have separated from the sheetrock for a few inches causing a "crack" in the texture and paint. I can easily push the edge back down against the drywall, but what is the best way to secure it? Is there any adhesive that would work, or do I have to run screws through it and patch the finish?
