How to use fiberglass tape?
To use this tape, cut and stick sections of the tape directly over the bare drywall joints. After the tape is in place, taking care not to overlap the tape anywhere, you will apply wet joint compound, pushing it through the holes in the me sh and into the seams beneath the tape. Like paper tape, you'll need to let the seams dry, and then apply additional thin coats of compound over the tape.
