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.

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.
