I recently ran into a situation that I've never seen before and I was wondering if anyone else has run into it.
I've been remodeling my basement playroom. As part of the project, I wrapped the center carrying beam of the house with drywall where it stuck below the existing finished ceiling on either side - basically a 3" high by 10" wide soffit. It's about 16 feet long, so I used four 8-foot all-metal corner beads to finish the edges. While I was sanding it, I noticed a hair-line crack running along the length of the bead where the mud meets the metal. I stuck a plaster knife under the edge and the mud popped off. I slid the knife along the edge of the bead and watched in shock as all of the mud just popped off on both sides of the corner with no effort until I reached the joint between the two pieces. The mud was stuck on the other three beads just fine.
I've since primed the metal with BIN and re-mudded the bead. Everything seems good so far. I used lightweight Sheetrock compound, which is what I've used for 20 years with no problem until now.
Anyone have any theories about why that one piece wouldn't hold mud?
