How to Fix a Drywall Tape Bubble

Drywall tape bubbles can be an unsightly problem that detracts from the smooth appearance of your walls. Fortunately, fixing these imperfections is a straightforward process that requires a minimal amount of tools and materials.

How to Fix a Drywall Tape Bubble

This guide on how to fix a drywall tape bubble will walk you through the steps to effectively repair drywall tape bubbles, ensuring your walls look flawless and professionally finished. Whether you’re a seasoned DIY enthusiast or a novice, these easy-to-follow instructions will help you achieve a seamless result.

What is a Drywall Tape Bubble?

Before we dive into the steps to fix a drywall tape bubble, it’s important to understand what it is and why it happens. A drywall tape bubble forms when the adhesive bond between the tape and the drywall breaks, causing the tape to lift and create a bubble or blister on the surface.

It's Important to 
Address These Bubbles

There are several reasons why this can occur, such as improper installation techniques, moisture penetration, or movement in the underlying structure. Regardless of the cause, it’s important to address these bubbles as soon as possible to prevent further damage and maintain a smooth wall surface.

Why Fixing a Drywall Tape Bubble is Important

Aside from the obvious aesthetic issues, drywall tape bubbles can also lead to more significant problems if left unaddressed. As the bubble grows, it can cause the surrounding paint or drywall compound to crack and chip, creating an even larger flaw on your wall.

Additionally, bubbles that are not repaired may eventually lead to the entire section of drywall tape detaching from the surface, leaving behind a gap that will require extensive repair work. By fixing a drywall tape bubble as soon as it appears, you can avoid these potential complications and maintain the integrity of your walls.

Materials Required

To fix a drywall tape bubble, you will need the following materials:

Utility Knife:

This will be used to cut away any loose or damaged tape and create a clean edge for the repair.

Joint Compound:

Also known as “mud,” this is a thick paste used to cover joints and imperfections in drywall.

Drywall Tape:

Self-adhesive mesh tape is specifically designed for use with joint compounds.

Putty Knife:

Used to apply the joint compound and smooth out any excess.

Sandpaper:

Sand down any rough edges once the repair has dried.

7 Step-by-Step Guidelines on how to fix a drywall tape bubble

Step 1: Prepare the Area

Before you begin the repair process, it’s important to prepare the area to ensure a successful fix. Start by placing a drop cloth or plastic sheeting beneath the repair site to catch any debris or falling compound. Use a utility knife to carefully cut around the perimeter of the bubble, removing any loose or damaged tape. Be sure to cut slightly beyond the bubble to ensure that only well-adhered tape remains.

Once the damaged tape is removed, lightly sand the area to create a smooth surface for the new tape and joint compound. Clean the area with a damp cloth to remove any dust or debris, and allow it to dry completely before moving on to the next step.

Step 2: Apply Joint Compound

Now that the area is prepared, you can begin applying the joint compound. Using a putty knife, scoop a generous amount of joint compound and spread it evenly over the area where the bubble was removed. Make sure to cover the entire exposed section and slightly beyond the edges to ensure a smooth and seamless transition.

Apply a thin, even coat and feather the edges to blend it into the surrounding wall. Smooth out any ridges or lumps with the putty knife, as a smooth surface will make it easier to apply the new tape. Allow the compound to dry completely according to the manufacturer’s instructions before proceeding to the next step. This drying time is crucial to ensure that the compound sets properly and creates a solid base for the new drywall tape.

Step 3: Measure and Cut the New Tape

While waiting for the joint compound to dry, you can measure and cut the new tape. Using a utility knife or scissors, cut a piece of drywall tape that is slightly longer than the length of the repair area. You may also want to consider cutting multiple pieces if your repair site is particularly large.

You can also use mesh tape that is pre-cut to standard lengths, which may be more convenient for smaller repairs. Simply cut the tape to the desired length and set it aside until the joint compound has fully dried.

Step 4: Apply the New Tape

Once the joint compound has fully dried, you are ready to apply the new tape. Begin by positioning the cut piece of drywall tape over the repair area, ensuring that it is centered and covers the entire section where the bubble was removed. If you are using self-adhesive mesh tape, simply press it firmly onto the joint compound. For traditional paper tape, you will need to lightly embed the tape into the compound with your putty knife, taking care to smooth out any air bubbles and ensure good adhesion.

The Joint Compound 
Using Your Putty Knife

Gently press the tape into the joint compound using your putty knife, starting from the center and working your way outward. This technique helps to eliminate any trapped air and ensures that the tape is securely bonded to the wall. Once the tape is firmly in place, apply a thin layer of joint compound over the tape, feathering the edges to create a smooth transition between the patched area and the surrounding wall. Allow this layer to dry completely according to the manufacturer’s instructions before moving on to the next step.

Step 5: Additional Layers

Depending on the severity of the bubble and the depth of your repair, you may need to apply additional layers of joint compound. If this is the case, simply repeat steps 2-4 until the desired thickness is achieved. Be sure to allow each layer to dry completely before proceeding to the next. Once satisfied with the smoothness and thickness of your repair, lightly sand any rough edges or ridges using fine-grit sandpaper. Wipe away any dust before moving on to step 6.

It’s important to note that each layer of joint compound should be slightly wider than the previous one, gradually blending it into the surrounding wall to create a seamless finish.

Step 6: Apply a Primer Coat

Before painting or applying texture over the repaired area, it’s best to apply a primer coat to ensure an even finish and proper adhesion. Use a paintbrush or roller to apply a thin coat of drywall primer over the entire repair site. Allow this layer to dry completely before moving on to the final step.

Use a Paintbrush or 
Roller to Apply a Thin Coat

You may also want to consider using a stain-blocking primer if the repaired area has been affected by water damage.

Step 7: Finish with Paint or Texture

With the primer coat fully dried, you can now finish the repair by applying paint or texture to match the surrounding wall. If you are painting, use a paintbrush or roller to apply a thin, even coat of your chosen wall paint over the repaired area. You may need to apply multiple coats to achieve full coverage and a uniform appearance. Allow each coat to dry completely before applying the next.

If your wall has a textured finish, consider using a matching texture spray or application method to blend the repair seamlessly with the rest of the wall. Apply the texture as per the product’s instructions, and make any necessary adjustments to achieve a consistent look. Once satisfied with the texture, you can paint over it with your chosen wall color if needed.

Following these steps on how to fix a drywall tape bubble will help you successfully repair and eliminate any bubbles or blisters in your drywall, restoring the wall to its original smooth appearance. Remember to take your time and follow the instructions carefully for the best results. And with a little practice, you’ll become a pro at repairing drywall bubbles in no time!

Conclusion

Repairing bubbles in drywall may initially seem daunting, but with the right tools and a methodical approach, it is a manageable task. By carefully preparing the surface, applying joint compound, and properly attaching new tape, you can achieve a seamless and professional finish.
