Sometimes the bubbles don’t appear until after the joint compound has dried. 3- Fixing the Bubbles After the Compound has Dried Once secured, do not forget to apply a coat of mud over them. Lay the two halves of the tape back in place and apply pressure to secure it. This time the third cut should be extended to the two vertical lines folding back the two halves of the tape.įinally, apply the coat of fresh joint compound to the seam. Then make an additional cut along the seam. The cut should be longer than the bubble’s width but should not reach the edges of the tape you need to fix. Or, if you want to fix it, start by making two vertical cuts that should lie on either side of the bubble. In this case, removing the entire tape and starting from scratch is best. It can be tricky to fix if you notice the bubbles straddling the seam. To make the tape adhere better, scrape it into fresh mud and re-coat it. If you notice the bubbles closer to the edges of the tape, consider fixing them by lifting the tape slightly and adding more mud underneath it. If a part of your tape has lifted and created a bubble, spread more joint compound mud underneath that section to help create a stronger bond and prevent the bubble from reappearing. Apply a coat of mud to new tape that can help it adhere better let the mud dry before adding any additional coats.Ģ- Spread Some Mud Under the Drywall Taping Then apply a new layer of joint compound (mixed with water to a creamy consistency) using a 6-inch knife and use the 10-inch knife to flatten and smooth it out.Įnsure that you apply the layer below the removed taping and the layer is slightly wider than the removed tape to avoid weak bonds.įinally, apply a new piece of tape while overlapping the cut edges by about 1/2 inch. If there are bubbles throughout, remove the entire tape. The most common and effective method is to cut out the bubbled section of the tape with a utility knife and remove the tape to check the bubbles.

Here are a few ways to fix the problem… 1- Make a Cut and Repair the Tape In most cases, it’s best to fix the air bubbles in the drywall before you finish the joint.īecause if you leave the bubbles as is and add the joint compound on top, the bubbles will reappear once the joint compound dries and the wall is painted, making your overall paint job look terrible.
