I'm doing my first drywall taping, and I need some advice. I did a "test
strip" on one seam, using the perforated tape which the instructions say to
put down on the dry seam, then cover with a coat of mud, pushing the mud
through the perforations.
Now I have a couple of spots with bubbles in the tape, and there is a
"bubble" down the one entire edge of the tape. In other words, this isn't
going so well.
1. How do I fix what I've done so far?
2. How do I avoid this the next time?
