Joining butt end to tapered.
Yeah, I wasn't about to use fiberglass. I taped a bunch of inside corners today using paper and premixed green bucket wetted down to make it extra sloppy. They were not kidding when they said that stuff drys fast. In retrospect, I think I would have done better to work shorter lengths at a time since I don't work nearly as fast as a professional taper- actually faired better on the shorter sections I had to do. Still haven't taped my built up sections of tapered to non-tapered. They need one more base coat after drying. There is still enough taper left so I can at least hide that one side without having to hump it.
