How to Get a Bubble Out of Sheetrock

Repair

• 1

  Cut a slit down the center of the drywall bubble with a razor blade.

• 2

  Dip a Q-tip in water and force the wet Q-tip behind the slit drywall tape to wet it. Remove the Q-tip.

• 3

  Smooth the drywall tape back against the joint compound to get rid of the bubble.

Replace

• 4

  Insert the tip of the razor blade behind the bubbled piece of drywall tape, and slice it away from the sheetrock joints. Discard the old piece.

• 5

  Mix enough drywall joint compound to resmooth over the area. Follow the compound mixing instructions. Many joint compounds require 1 1/2 gallons of water per one bag of joint compound.

• 6

  Apply a generous amount of joint compound with a 6-inch knife to the seam that is now exposed from the piece of drywall tape removed.

• 7

  Flatten a new piece of drywall tape over the compound. Wipe down the length of the tape with your hand, using moderate pressure.
