1st drywall mud/ tape applied, some lifting edges
I've done the first pass of mudding the joints and the wetted paper cut to each, it has gone pretty well. ;) however a few spots of this tape have had edges lift as they dried:(- guess I got too much mud squeezed out from under it. :eek:
Is this something to fix before the 2nd coat of mud? If so, how? Do I trim it back to where it is firm with a sharp utility knife? force in mud under the edge and let dry? Or just ignore it and trust/ hope the 2nd-3rd+ layers work to settle it?
should 3rd+ skim coats be a thinner finish grade mud?

Oh my God! WHAT?!?!?! :p;):D
Yeah, it sounds like you were a little aggressive with your mud removal. You can deal with the tags in a few different ways.
[LIST=1][*]edges can be lifted and mud worked under, then gently smoothed flat again. Bubbles can be sliced and filled in the same manner.[*]larger tags can be removed altogether. The tape really just needs to span the joint, a little off the side isn't going to hurt anything. Key words, "a little", meaning a few inches. If you remove more than that, you run the risk of the tape failing should there be any movement in the wall.[/LIST]
If you don't reseal loose edges and bubbles, they will continue to telegraph through the proceeding layers of mud.
