I'm trying vinyl corner bead on a couple of outside corners on my basement project. In watching a few videos on YouTube about it they recommend using Trim Tech 847 or 3M Super 77 spray adhesive along with staples to secure it to the drywall. I installed one strip last night using 1.25" pneumatic staples and no adhesive. It was before I watched the videos. Looking online, the local Lowe's carries neither of the mentioned adhesives. Anyone try another adhesive? The one I put on last night seems to be solidly attached between the mud and the staples. Skip the adhesive? A couple of the YouTube videos show it just being stapled with 1/2" staples which would only staple it to the drywall, my pneumatic staples would get into the framing, though you really need to scale back the air pressure to keep from shooting through the vinyl.
3M 90 says it is good for drywall and plastics, though doesn't specify what types. It is in stock at my local Lowe's.
