In Response To: joint compound taping (Marty)

I can only guess judging by the date that you have probably already corrected the spot. Nonetheless,the bubble that you see was caused by the lack of mud (joint compound) in that particular spot . The mud acts as an adhesive. Although most compounds come in 5 gal. buckets and say "ready- mixed", that merely means that the compound isn't in dry (powder) form and requiring mixing. When applying tape, the mud should be watered down slightly in order to allow the mud to flow between the tape and drywallleaving a thin layer of mud between the two to act as a adhesive. Any bubbles noticed can be repaired by carefully taking a razor knife and slicing the bubbled areaand forcing mud into it and then gently running the taping knife over the spot to flatten or smoothe it back out. If you notice the bubble before the mud has dried,simply pull the tape away from the drywall and apply mud to the missed area. If a bubble isn't corrected, any time you apply another coat of mud or even when it is time to paint, the bubble will jump out at you. Hope this helps you out in future projects.
