If you’ve ever noticed bubbles forming under drywall tape, you’re not alone. It’s a common problem when drywall isn’t installed properly or over time due to temperature changes or moisture. Bubbles in drywall tape can make your walls look uneven and messy, but the good news is that you don’t have to live with them. With a few simple steps, you can repair the bubbles and restore your drywall’s smooth, clean look. Here’s an easy guide to how to fix bubbles in drywall tape.
1. Understand the Cause of the Bubbles
Before fixing bubbles, it helps to understand why they appear. Bubbles in drywall tape usually form when the tape wasn’t applied correctly. If too much air gets trapped between the tape and drywall mud, bubbles will form as the mud dries. Another cause can be moisture or temperature changes, which cause the materials to expand or contract, leading to bubbles.
To prevent bubbles from forming again, make sure the drywall tape is applied smoothly and evenly the first time. Always use high-quality materials and follow the proper steps when learning how to fix bubbles in drywall tape.
2. Gather the Right Tools
Having the right tools will make the repair process quicker and easier. You’ll need:
- A utility knife
- Sandpaper (fine grit)
- A putty knife
- Joint compound or drywall mud
- Drywall tape (if you need to replace it)
- A sanding block or pole sander
You can find these tools at most hardware stores. It’s important to use the correct tools to ensure a clean and professional-looking repair.
3. Cut Away the Bubbled Tape
The first step in how to fix bubbles in drywall tape is to remove the damaged drywall tape. Take a utility knife and carefully cut around the edges of the bubbled area. Be gentle to avoid damaging the surrounding drywall. Once you’ve cut around the bubble, peel away the tape. If the bubble covers a large area, you may need to remove a bigger section of tape.
Cutting out the bubble allows you to start fresh with smooth drywall, which will make the repair look better and last longer.
4. Sand the Area Smooth
After removing the bubbled tape, you’ll need to sand the area smooth. Use fine-grit sandpaper to lightly sand the surface, removing any leftover adhesive or joint compound. Sanding creates a smooth surface that will allow the new drywall tape to adhere better.
When sanding, wear a mask to avoid inhaling the dust. Once you’re done sanding, wipe away any dust with a damp cloth to prepare the surface for the next step.
5. Apply a Fresh Layer of Joint Compound
Now it’s time to apply a joint compound, also known as drywall mud, to the area where you removed the tape. Use a putty knife to spread a thin, even layer of joint compound over the entire area. Make sure to smooth out any lumps or ridges. The key is to apply the compound in a way that will allow the new tape to lie flat.
Let the joint compound dry completely before moving to the next step. Depending on the type of compound you use, drying time can vary, so check the instructions on the packaging.
6. Replace the Drywall Tape
Once the joint compound is dry, it’s time to reapply the drywall tape. Cut a piece of tape that fits the area you just repaired. Press the tape firmly into the wet compound, making sure there are no bubbles or wrinkles. Use your putty knife to smooth the tape and press it into the joint compound.
Applying the tape correctly is one of the most important steps in this process. If you rush or don’t press the tape down properly, you may end up with more bubbles.
7. Apply Additional Layers of Joint Compound
To finish the repair, apply another thin layer of joint compound over the tape. Use a wide putty knife to spread the compound evenly over the tape and surrounding drywall. This step helps blend the tape with the wall, making the repair less noticeable. After the first layer dries, sand it smooth, and then apply a second layer if needed.
Be patient and allow each layer to dry completely before sanding. Once the final layer is dry and smooth, your wall should look as good as new!
Bonus Tip: Prime and Paint for a Finished Look
Once the repaired area is smooth and free of bubbles, you can prime and paint the wall to match the rest of the room. Use a primer that is suitable for drywall repairs to ensure the paint adheres properly. After the primer dries, paint the wall in your desired color.
This final step not only makes the repair invisible but also protects the wall from future damage.

Repairing bubbles in drywall tape is a simple process that can make a big difference in the appearance of your walls. By understanding the causes, using the right tools, and following these seven quick tips, you can easily fix any bubbles and restore a smooth, clean finish to your drywall.
