   Hi Todd,

   My guess is that the space between the sheets you are taping is to wide.  In this case the mud dries in the space and shrinks while the tape on the board dries normally.  When dry the tape between the boards pulls away from the mud and leaves the bubble.  So either use the fiberglass stuff or tighten up the gaps.

   Compound is drying very fast or having the water sucked out of it. pre-wet the tape in a bucket but wipe off the excess water with your fingers first. Use a setting type compound first (durarock, etc.) for easier results.

   You can also alleviate a good deal of the problem by setting tape with setting compound. Not the easy sand stuff, but regular Durabond. If you have large voids for whatever reason, you can also use the Durabond to fill those first. Since switching to setting compound for tape, the number of bubbles I get has gone to almost nil.

   I have run into this problem in the past, where a patch joined already painted drywall. The area over the painted rock would lift and bubble while the tape over the fresh rock would hold perfectly.

   We thought that the moisture coming out of the mud and not being able to get through the paint was causing the problem. Switching to fibertape for the patches cured it anyway.

   What were the weather conditions when the tape was applied?  Did it rain for a few days or several days of high humidity?

   Are you using the joint compound right out of the bucket? If so , thin the mud with some water. Always stir or mix the mud before using. Most ready mix joint compounds have a thixathropic  agent added to them to lessen the settling and seperating tendency of pva containing products. Kind of acts like a gel to help suspend the solids. Mixing or stirring releases all the components from the suspension so they work the way they are suppose too.

   In his first interview since the stroke, Ram Dass, 66, spoke with great difficulty about how his brush with death has changed his ideas about aging, and how the recent loss of two old friends, Timothy Leary and Allen Ginsberg, has convinced him that now, more than ever, is the time to ``Be Here Now.''
