Tried those fiberglass mesh tapes for a butt joint and got a huge surprise
Figured I'd give it a shot on a ceiling patch last Tuesday since paper tape always bubbles on me there, but the mud cracked right through the mesh after 3 days. Has anyone else had that happen or did I just pick bad tape?
Watch those inside corners though, paper tape loves to bubble up if you dont press it tight enough with the mud. A 6 inch knife on the first coat saves you a ton of sanding later. Keep your mud a little looser than you think you need and it'll embed way better.
