How to fix bubbling drywall tape. Whether you use paper tape or fiberglass mesh tape, you’ll have to take time out of your day at one point to sort them out.
It doesn’t matter if you’re covering joints in new sheetrock or patching up holes that have been made, bubbles should be the last thing on your mind before applying.
If you get the mud in at least 1/8″ thick on either side of the seam with seams covered thick enough so there are no pesky air pockets (they can pop over time).
You won’t have this problem to worry about as they’ll hold firm and smooth as they’re meant to without any blisters appearing in the end.

You might encounter an air bubble within the tape of your drywall if you notice it. Air bubbles occur when there is not an adequate bond between the tape and the joint.
In general, there must be an outstanding joint to fill any holes before painting over to prevent the tape from showing through. To fix the bubbling drywall tape method is mentioned below.
Be sure to mark the spots
The bubbling often happens along the edges of the painted surface, so firstly we want you to mark this portion down to make sure there are no further damages.
You see, sometimes we make too big a deal about bubbles and little holes in the walls when in reality it isn’t such an important thing as people tend to exaggerate about these things.
It would be better if you repair them with paint instead. Marking areas that had been affected by bubbles with a pen will help your repairing process become quicker and more accurate.
Remove bubbles from a small area
Identify different bubble structures: bubbles close together, air under the base coat, and a lift-up cap on a tight cluster of bubbles are most common.
If you have lift-up caps lifting up in the middle of your job, cut through these and pop out the air with your utility knife.
Apply mud over top to hide it back down into the basecoat and smooth it out using overlapping “S” movements with your knife for a radius about 2 times wider than the bubble itself. After applying mud over tapes (which I know is one of those things you’d rather not do).
If you see giant air pockets that can’t be patched without removing too much paint or there are many large bubbles clustered around each other, carefully dig them all out to remove just the air pocket and then apply fresh mud over top.
Remove bubbles over a wide area
Cutting a fresh layer of mud to re-cover tape joints can be a time-consuming process. Depending on your preference, you may also have to deal with excessive amounts of paint buildup which could obscure the aesthetic quality of the mud layer.
Professional painters commonly recommend using Mud Tape as an alternative solution that is more cost-effective and results in faster results; here are some instructions for applying it:
Cut off a piece of the tape measuring approximately 1/16th inch larger than the area you want to cover and lay it out across the taped joint. Press down on both ends to secure it into place.
Keep pressure consistent so as not to disturb its integrity; Scrape away any excess paint around the joint by evenly pressing a sharp knife against the tape.
*Fill in any cracks or holes with plaster or mud and let dry overnight; Once solidified, use your paint roller given that you’re dealing with large areas or airbrushing depending on how small your job is.
Applied Finishing Coats
Apply a second layer of the bed and tape to the joint. Smoothly apply pressure over the areas where you taped and spread evenly over the area using even pressure.
In areas where spots, nails, or small pieces of wood are present, apply extra mud in layers of one to two inches. Smoothly spread this over the areas as well.
Apply another thin coat to this area that is 6 inches wide to give a nice smooth finish and bring more balance to all sides of your corner bead wall. Lastly, let everything dry for about one day before you move into the next phase.
Sanding and finishing
Once the mud has dried, now it’s time to give it a sanding. You should have already taken precautions by wearing goggles, a mask, and gloves since you’ll be dealing with some of the dust that may arise when you begin this step.
Make sure that if any paint remnants are on the house, you finish up any leftover touch-ups before moving on to the next step of prepping for painting.
Make sure to use 120-grit sandpaper or coarser elsewhere and be careful with those areas where seams and screws may be located so as not to damage them.
You want to take the time necessary to ensure that you get every piece of your home fixed up before painting can commence.
