KingdderDrywall Joint Tape 2" x 132' PVC Multipurpose Self Adhesive Joint Tape Drywall Corner Line Wall Crack Self Adhesive and Patch for Inside and Outside Corner Bead, Ceiling Wall Crack Filling

Used to join wall and ceiling and plaster over. Worked very well and stuck well enough to plaster over

I used it for both inner and outer corners, and it worked as intended. However, the tape peeled out at a few spots when I used it on an outer corner. I had to sprayed the sheet rocks first with 3M Super 77 to make sure there was no peeling, and it worked great after that.

I liked the idea that this could be used as corner bead, or just joint tape in general. It is supposed to be self adhering. However, in order to use it in an outside corner like it was shown, it will not self adhere. It pulls off, up and down the whole joint. So you have to put screws in it like regular corner bead. The problem is, is this causes buckles. Buckles become difficult to patch. And you can lessen the high spots by adding more screws. Like an absurd amount of screws. This joint tape is ultimately just really expensive regular (super thick) joint tape.
