Blisters in drywall tape can be a frustrating issue, whether you’re remodeling your home or doing a quick repair. If you’re not sure how to fix blisters in drywall tape, don’t worry! This guide will walk you through a simple, five-step process to repair drywall tape blisters easily. With these steps, you can make your walls smooth again and avoid future problems.
What Causes Drywall Tape Blisters?
Before we dive into the solution, it’s helpful to know why drywall tape blisters form in the first place. Blisters happen when the tape isn’t applied correctly or when there is air trapped underneath it. This often occurs when the surface isn’t clean, the compound wasn’t applied evenly, or moisture gets behind the tape.
Now, let’s get to the fix! Here’s how to fix blisters in drywall tape step by step.
Step 1: Remove the Damaged Tape
First, you need to remove the part of the tape that’s blistering. Use a utility knife to cut out the damaged section. Be careful not to cut too deep—you only want to remove the blistered tape and not damage the drywall beneath it.
Once you’ve cut the blistered area, gently pull the tape away from the wall. Make sure you remove any loose bits of tape that could cause more blisters later on. If you leave small pieces behind, they can lead to more problems down the line.
Step 2: Clean and Prep the Area
Next, clean the area where you removed the tape. Dirt and dust can stop the new tape from sticking properly, so it’s important to get rid of them. Use a damp cloth to wipe the surface and let it dry completely before moving on to the next step.
If there are any uneven areas or holes, use sandpaper to smooth them out. A smooth surface helps the new tape and compound bond to the wall without trapping air bubbles.
Step 3: Apply a New Coat of Joint Compound
Now it’s time to apply a fresh layer of joint compound. Use a taping knife to spread a thin, even layer over the area where you removed the blistered tape. The compound should be thick enough to hold the new tape but not too thick that it causes lumps.
Be sure to spread the compound a little beyond the edges of where the old tape was. This ensures that the new tape has enough compound to stick properly and blend smoothly into the wall.
Step 4: Re-Tape the Area
Once the compound is applied, press a new piece of drywall tape into the wet compound. It’s important to use paper tape instead of mesh tape for this fix. Paper tape is less likely to blister in the future because it doesn’t allow moisture through as easily.
Smooth the tape with your taping knife, making sure there are no air bubbles underneath. Work from the center of the tape out toward the edges to push out any trapped air.
Step 5: Apply a Final Layer of Compound and Let It Dry
After you’ve smoothed out the tape, apply another thin layer of joint compound over the top. Make sure the compound covers the tape entirely, extending a few inches past the edges of the tape.
Let this final layer dry completely. Drying time can vary depending on the type of compound you use, so check the package for specific times. Once it’s dry, use sandpaper to smooth out any rough spots or uneven edges.
After sanding, your repair should blend in with the rest of the wall. If necessary, apply a second coat of compound, sand it again, and then your wall will be ready for painting.
Preventing Future Drywall Tape Blisters
Now that you know how to fix blisters in drywall tape, it’s important to prevent them from happening again. Here are a few tips to help you avoid future problems:
- Use quality materials: Always choose high-quality drywall tape and joint compound to ensure a strong bond.
- Keep the surface clean: Dust, dirt, and grease can stop the tape from sticking, so make sure the wall is clean before applying compound and tape.
- Avoid moisture: Moisture is one of the leading causes of blisters, so it’s important to control humidity in your home. Use a dehumidifier if needed to keep moisture levels low.
Conclusion
Fixing blisters in drywall tape doesn’t have to be hard. By following these five simple steps, you can repair the damage quickly and make your walls look smooth again. Remember, start by removing the damaged tape, clean the area, apply a fresh coat of compound, re-tape, and finish with another layer of compound.
