How to fix bubbles in drywall take? Drywall tapes are a common part of households. People use drywall tape to cover drywall seams, and these tapes are very adhesive, resistant, and durable. But still, drywall tapes can bring many issues to you. One of those issues is drywall taping bubbles. There could be several reasons behind such a problem.

However, the main reason is installing drywall tapes poorly. So, you need to know how to fix bubbles in drywall tape. This article will discuss 5 key steps of drywall tape repair.

Understand the Reasons for Bubble forming on Drywall Tapes

It is essential to know the reasons for bubbles forming before you can begin fixing the problem. So, why does drywall tape bubble? One of the main reasons is loose installation.

Some sections of the tape may get loose during installation. As a result, those sections can attract air to clog. Thus, the loose sections will end up being bubbly.

You can also notice bubbles in the joint compounds. This happens due to embedding the joints loosely. Such unfinished works in the joints can happen when you are in a hurry. You may intend to finish the project quickly. As a result, you might have left empty spaces underneath the tape. This can form bubbles in the empty joints.

The third reason for bubble forming is using inconsistent compounds. If you use too thick compounds, the chances of forming bubbles get higher. This happens because it is tough to spread thick compounds. Also, some compounds may even get dry soon. It can create unevenness and cause bubbles to form.

The final reason could be with the adhesive you use. If you scrap the adhesive too hard, it can uplift the tape a bit. When the wall absorbs the moisture, air might sneak inside the tape. This can create air bubbles in the drywall tape.

Tools and Materials Needed for the Task

Knowing the reasons for the bubble forming may not be enough to prevent it. You might have to fix the issue on your own. Before we jump into the repairing process, we need some tools in our hands. Firstly, you will need some new tape. Then you will need a knife and a marking pencil. These two are used to mark and cut the bubbly areas. It is better to get a 5 inches long knife.

Step 2: Fixing the Bigger Spots

Now begin the fixing process with the smaller areas. Find the marked areas that have small bubbles formed. Take the knife out and cut through the tape to get the air out of those areas.

Once the spot is clean, take some mud from the mud pan. Apply mud over the spot and also on both sides of the tape. Use the knife to smoothen the mud layer.

After this, move on to the bigger areas. You will see many bubbles forming together in the tape. This requires you to cut the whole tape out from the spot. So, cut out the circular areas that you marked on the first step. Then apply mud again on the whole spot very carefully.

Step 3: Fixing the Wider Areas

Now it is time to move to the wider areas. In this step, your task is to fix wider areas of bubbles. You will see bubbles popping up all over these areas covering more than 2 inches in diameter. You will need to apply new drywall tape on these spots.

Begin the process by cutting off the tape from the complete area. Then remove mud and apply fresher muds all over the wall. After this, measure the length and area of the spot. This will help you to cut a new tape to the exact area of the spot. It is best if you use a paper joint tape this time.
