Bubbles in Drywall Tape? Fix It Fast with These Tips!

Bubbles in drywall tape can ruin the smooth, polished look of your walls. Luckily, you can fix this problem quickly with the right tools and techniques. Whether you’re patching up a small area or tackling a bigger project, these easy tips will help you get professional-looking results. In this guide, we’ll cover why bubbles form, how to fix them, and how to prevent them in the future.

What Causes Bubbles in Drywall Tape?

Before fixing the problem, it helps to know what’s causing it. Here are the most common reasons bubbles appear in drywall tape:

1. Not Enough Joint Compound

Joint compound, also called “mud,” is like glue for drywall tape. If you don’t use enough compound, the tape won’t stick properly, leading to bubbles.

2. Uneven Application

If you spread the compound unevenly, air can get trapped underneath the tape. This creates unsightly bubbles.

3. Old or Low-Quality Materials

Drywall tape or compound that’s old, brittle, or low quality is more likely to fail. Using fresh, good-quality materials ensures better results.

Step-by-Step Guide to Fixing Bubbles in Drywall Tape

If you’ve spotted bubbles in your drywall tape, don’t worry—it’s an easy fix. Follow these steps to repair the damage and restore your walls.

Step 1: Gather Your Supplies

You’ll need:

• A utility knife
• Sandpaper (medium grit)
• Joint compound
• A taping knife or putty knife
• New drywall tape (if needed)

Step 2: Remove the Bubbled Tape

Cut out the bubbled section of the tape with your utility knife. Be careful not to damage the surrounding drywall. Remove any loose pieces of tape.

Step 3: Sand the Area

Lightly sand the edges of the cut area to smooth it out. This ensures the new compound will adhere properly.

Step 4: Apply Fresh Joint Compound

Use your taping knife to spread a thin, even layer of joint compound over the damaged area. Make sure to cover the edges of the cut section.

Step 5: Replace or Reapply Tape

If the original tape is damaged, replace it with a new strip of drywall tape. Press the tape firmly into the compound to eliminate air pockets.

Step 6: Add a Second Layer of Compound

Apply another thin coat of compound over the tape. Feather the edges by spreading the compound outward to blend it with the wall.

Step 7: Let It Dry and Sand Again

Allow the compound to dry completely, which can take 24 hours or more. Once dry, sand the area lightly to achieve a smooth finish.

Tips to Avoid Bubbles in Drywall Tape

Once you’ve fixed the problem, you’ll want to prevent it from happening again. Here’s how to avoid bubbles in drywall tape in the future:

1. Use Enough Joint Compound

Make sure you apply a generous amount of compound under the tape. Without enough compound, the tape won’t adhere properly.

2. Smooth Out Air Pockets

Use a taping knife to press the tape firmly into the compound, smoothing out any air pockets as you go.

3. Work with Quality Materials

Invest in good-quality drywall tape and joint compound. These materials last longer and are easier to work with.

4. Apply Thin, Even Layers

Thick layers of compound can trap air bubbles. Apply thin, even coats for the best results.

Why You Should Fix Bubbles Right Away

Bubbles in drywall tape may seem like a small issue, but they can lead to bigger problems if left untreated. Over time, the tape may peel further, damaging the surrounding wall. Fixing bubbles promptly keeps your walls in good condition and prevents costly repairs later.

FAQs

Can I Fix Bubbles Without Removing the Tape?

For small bubbles, you can sometimes cut a small slit in the tape, press it flat, and apply compound over it.

How Long Does Joint Compound Take to Dry?

Joint compound usually takes 24 hours to dry, but drying times can vary depending on humidity and thickness.

Is Mesh Tape Better Than Paper Tape?

Both types of tape have pros and cons. Paper tape is less likely to bubble, but mesh tape is easier to work with for beginners.

Conclusion

Bubbles in drywall tape are a common but fixable problem. By cutting out the bubbles, applying fresh compound, and re-taping the area, you can restore your walls to a smooth, polished finish. Remember to use enough compound, smooth out air pockets, and invest in quality materials to avoid bubbles in the future.
