I've got a roll of "fiberglas" (at least I THINK it's made of that )joint tape that I got at HD. unlike regular paper joint tape, one side is sticky. does that mean it should be stuck to the joint first THEN mud applied?
Yep. Mainly just used for older plaster walls, or quick patch jobs. You can get the Paper tape that also has the sticky backing, but best way to do the job, is good ole paper tape with mud first, then mud over the tape.
