Why Do Drywall Tape Bubbles Appear After Drying & How to Fix Them?

Drywall helps make your walls smooth and clean. But sometimes, after you finish putting on the drywall tape, you see bubbles. These bubbles can look bad. They can make the wall look bumpy or uneven. This can be frustrating, especially after spending time working on the wall.

In this article, we will talk about:

• What drywall tape bubbles are
  

• Why they show up after drying
  

• How to fix them fast and easy
  

• How to stop them from coming back
  

Let’s start with the basics.

What Are Drywall Tape Bubbles?

Drywall tape bubbles are air pockets or raised spots under the tape. These bumps make your wall look messy. They can happen during or after the job is done.

They are not dangerous, but they look bad. If you paint over them, they still show. That’s why it’s important to fix them.

Why Do Drywall Tape Bubbles Happen?

There are a few common reasons why drywall tape bubbles appear after drying. Let’s look at the main causes:

1. Not Enough Joint Compound

Joint compound, also called mud, is the glue that holds the tape. If there is not enough mud under the tape, it won’t stick well. The tape then lifts and forms bubbles.

2. Drywall Tape Not Pressed Down

When the tape is not pressed firmly into the mud, air can get trapped. This trapped air turns into bubbles after the mud dries.

Use a taping knife to smooth the tape and push out air.

3. Using Too Much Mud on Top

Putting too much mud on top before the bottom dries can cause tape to float. This makes bubbles form under the tape.

Wait until each layer dries before adding more.

4. Old or Damaged Tape

Sometimes, tape that is old or low quality doesn’t stick well. This can also lead to bubbles.

Use paper tape or mesh tape from trusted brands.

5. High Humidity or Dampness

Too much moisture in the room can keep the mud from drying right. This can cause tape to lift and bubble.

How to Fix Drywall Tape Bubbles

Don’t worry! You can fix drywall tape bubbles with a few easy tools. Here’s how:

Step 1: Cut Out the Bubble

Use a utility knife to gently cut along the edges of the bubble. Remove the loose tape. Be careful not to damage the wall.

Step 2: Apply New Mud

Use a putty knife to spread a thin layer of joint compound in the empty space. Make sure it’s smooth and flat.

Step 3: Add New Tape

Place a new strip of tape on the wet mud. Press it firmly into the mud using your knife.

Step 4: Cover With More Mud

Add another thin layer of mud on top of the tape. Smooth it out and let it dry.

Step 5: Sand and Paint

Once dry, sand the area lightly. Then you can paint the wall to make it look new again.

How to Stop Bubbles Before They Start

Here’s how to keep drywall tape bubbles from happening again:

1. Use Enough Mud

Always use enough joint compound under the tape. The tape should fully stick to the mud.

2. Press the Tape Well

Use a taping knife to press the tape firmly. Push out all air bubbles.

3. Use Quality Materials

Use good joint compound and quality drywall tape. This helps everything stick well.

4. Watch the Room Temperature

Keep the room dry and warm. Avoid working in damp or cold places. This helps the mud dry evenly.

5. Let Each Layer Dry

Don’t rush. Let each coat of mud dry before adding more.
