My fiancee and I are attacking our second drywalling project. The first time we did our ceiling in the livingroom...and used regular paper joint tape. As time passed, we noticed air pockets appearing along the joints...as if the tape didn't stick very well (or was coming un-done) Now we are doing our entire bedroom...and were steered toward using self-adhesive joint tape(drywall finishing tape)...hoping to solve our taping problems. Now that we have much of the joints taped with this stuff (and 2 coats of lightweight...not quick setting... joint compound on) we are already noticing that the tape is pulling away from the walls. (like air pockets along the joints) What are we doing wrong?

1st of all are you making sure the drywall edges are butted tight together Do not expect tape or joint compound to fill the gaps without bubbling if you have gaps between sheets or pieces of drywall use a thick type of spackling compound 1st let dry then use tape and "mud" joint compound

After you put the tape over the joint go over with a thin coat of compound making sure that the tape is meshed and covered .Give it a few minutes to set and put another coat of compound a little ticker,spreading from the center of the tape (if horizontal)up and another coat going down.If it is vertical go right and left,making sure that there is no gap in the center of the tape.
Take a large plaster knife,about 13-15 inches and smooth the plaster.Let it dry and the put a second coat without sanding,when this coat is dry sand it lightly.

You must not have gone over the original perf compound enough...I have drywalled a thousand houses and have never had a seam come loose....you have to work the coating as flat as you can, let dry thoroughly, then sand smooth...I have never tried adhesive perf tape before...

Is the self-adhesive tape paper or fiberglass?
I always soak paper tape in water before I put it on the mud. Fiberglass is quick, but harder to cover-up.

the best trick is to use self sticking tape and 3 coats of lite weigth mud, if you get some air pockets cut them out and fill with mud., problem is general mud is to thick try thinnung with water
