1 How Do You Fix Bubbles in Drywall Mud? 2 Why Does My Drywall Mud Have Bubbles in It? 4 How Do You Prevent Bubbles in Drywall Mud? Conclusion In drywall mud, bubbles are undesirable. They keep the wall from being perfectly flat and leave a surface that is uneven for the first coat of paint.
Fortunately, as long as you can pinpoint the source, these bubbles are simple to correct.
The most frequent reason for drywall mud bubbles is improperly taping the joints. The tape must be taken off, more joint compound must be added, and new tape must be applied in order to solve this issue.
You should be aware of the following.
HOW CAN BUBBLES IN DRYWALL MUD BE CORRECTED?
Follow these instructions to correct any bubbles in the drywall mud behind your paper tape:
Cut above and below the bubbles with a utility knife, then take off that piece of tape. After removing the tape from the drywall seam, add a layer of drywall compound. (This layer ought to be a little bit wider than the tape’s width.) Cut a piece of tape to size for the area. Over the recently applied joint compound, apply the tape. Now, beginning at the top, evenly cut through the tape with your drywall knife. Continue doing this until the paper is well imbedded in the joint material and all trapped air has been let out. Applying a 1/16th inch coating of joint compound over the drywall tape will complete the task once the drywall mud bubbles have been repaired. After that, you must wait for the mud to completely dry, which should just take a day.
After applying a second coat of joint compound that is about 1/16th as thick as the first, let it dry, and then sand it to a smooth finish.
You don’t need many equipment to remedy the problems if the paper tape caused bubbles in your drywall mud. Most of these are presumably already available to you.

The first reason is that the paper tape you used has air trapped behind it.
For people who don’t have a lot of drywalling experience, this is a typical issue. It happens because not enough joint compound was applied to the drywall joints before the tape was applied, and because the air was not sufficiently released after the tape was applied.
Air becomes trapped behind the tape when this happens. The air bubbles or blisters in the compound become very obvious as it dries.
The texture of the wall you are putting the mud to is the second most frequent cause of air bubbles.
The moisture content of drywall compound does two things when it dries: it absorbs and it evaporates. This implies that while part of the moisture evaporates into the air, some of it gets absorbed into the sheetrock.
The drywall cannot absorb the moisture if the first application of joint compound is blocked by a barrier (such a painted surface), therefore the moisture escapes as tiny bubbles.
You might try sanding the bubbles down and then reapplying the joint compound after adding a solution like No Pock Pro . As an alternative, you may mix some dish soap into your drywall mud.
HOW CAN BUBBLES IN DRYWALL MUD BE PREVENTED? As long as the drywall mud didn’t go bad, there are a few precautions you may take to avoid bubbles. Make sure the drywall compound is completely blended to the correct consistency first; it should have the consistency of frosting. If you are not utilizing a premixed substance, this is very crucial.
Second, when taping the seams of the gypsum drywall, be sure to use enough compound for the first coat before you start taping. To embed the paper tape in the mud and let the air bubbles out, use your drywall knife. This will stop the mud from blistering.
Finally, add a product called No Pock Pro to your drywall mud before applying it to the wall if you’ll be applying compound over painted drywall.
CONCLUSION Bubbles in drywall can usually be repaired and are simple to avoid. Especially in joints using paper tape, bubbles in drywall mud are fairly uncommon to notice. If this is occurring to you, consider removing the tape and putting a new layer of tape down after spreading a thicker, more equal layer of joint compound. After that, use your drywall knife to remove any trapped air.
