Apply a thin layer of compound over the strip of drywall tape. This layer of mud doesn’t need to be thick to cover everything. You want to have a smooth, thin layer of mud that covers the entire tape. Pull the compound from one end of the tape to the other. Apply More Mudįinally, scoop a small amount of joint compound onto the edge of the taping knife and apply the mud over the new piece of tape. Small wrinkles are okay because you can fix those next. Press evenly to embed the tape into the compound and remove bubbles. There can be no bubbles in this new tape. Use the putty knife to smooth out the tape so that it lays flat on the drywall seam. Press one end of the new piece of tape to the gap, then make sure it overlaps with the existing tape. Hold onto the top edge of the tape, and pull the drywall knife down onto the tape. The additional length will ensure there are no gaps between the pieces of tape.Ĭenter the tape over the area and place it directly on the drywall compound. Make the measurement about ½ inch or 1 cm. It should be big enough to overlap the existing tape beneath the coat. Cut out or tear a piece of drywall tape again. The additional mud doesn’t solve the problem entirely by itself. Now you can’t leave the cut-out area bare. A few more coats of mud will help even everything out and keep it looking consistent. You might see the area in the mud where you cut out the bubble, but that’s fine because you’ll solve that problem. Add the compound so that it’s slightly wider than the width of the tape. You don’t want one section to look uneven or flatter than another. Makes sure you cover the entire drywall tape. Put the mud on the knife and run it over the area you cut out. Depending on the area of the bubble you cut out, you may want to use a different taping knife to float that joint compound easily with no issues or lumpiness. You can use the same taping knife as before or a new one. Toss it away because you won’t need it again. It will come off pretty easily, especially if the mud is still wet. Once you’ve cut the top and bottom of the bubble, peel it back from the rest of the seam. The blade should be relatively sharp so that all you need to add is some light pressure. You don’t have to press too hard into the mud. Stop where the mud starts to appear solid again. Take the knife and drag it underneath the bubble all the way to the other end. Take your utility knife and start for the end of the bubble formation. From there, they can pop out because of the wetness on the surface. They could appear after you get the tape wet again. Sometimes, you won’t see bubbles immediately. Either there wasn’t a good bond, or you may have pushed too much mud out from behind it when you taped. The bubbles come from a loose installment. But once you start to apply a few coats of mud, you’ll see maybe one or two bubbles form. Naturally, there might be a few wrinkles in the tape, and you may figure that’s normal because it is. Once you apply the drywall tape on the seam, it looks relatively normal. The covered drywall seam will shrink, warp, or crack with too much sanding. Sanding through the bubble will only wear through the drywall tape, and you need that to stay intact. The bubbles come from air trapped behind the tape. Sanding may seem like a good option at first, but it’s not. Plus, the bubbles will be far more noticeable with paint on top. Underneath, the bubbles still exist, and they could create further issues down the line. Do not, under any circumstances, paint over the bubble on your drywall tape.
