How to Fix Bubbles in Drywall Tape – Expert Guide
Bubbles in drywall tape can make your walls look uneven and messy. They happen when the tape doesn’t stick well or when air gets trapped underneath. While these bubbles can seem like a big problem, fixing them is easier than you might think. With some simple tools and a little time, you can make your walls smooth again.
This guide will help you fix bubbles in drywall tape step by step. It will also show you how to stop bubbles from coming back in the future.
What Causes Bubbles in Drywall Tape?
Bubbles in drywall tape happen because of a few common reasons:
- Not enough compound: The tape needs joint compound (sometimes called mud) to stick. If there isn’t enough, the tape won’t stay flat.
- Too much compound: Using too much compound can trap air under the tape, causing bubbles to form.
- Skipping steps: Drywall taping takes patience. Rushing can lead to mistakes like bubbles.
- Poor materials: Cheap tape or compound can make it harder to get a good finish.
- Dusty or dirty walls: Dirt and dust on the wall can stop the tape from sticking properly.
Tools You Will Need
Before you start, gather the tools and supplies you’ll need:
- A putty knife to spread the compound.
- A utility knife to cut the tape.
- Drywall compound for repairs.
- Sandpaper (medium and fine grit) to smooth the wall.
- Drywall tape if you need to replace old tape.
- A damp sponge for cleaning the wall.
How to Fix Bubbles in Drywall Tape
Follow these easy steps to fix bubbles in your drywall tape:
1. Look at the Bubbles
Check how big the bubbles are. Small bubbles can be fixed easily, but bigger bubbles may need more work.
- Small bubbles: You can flatten these without removing the tape.
- Large bubbles: You’ll need to cut out the bubbled area and add new tape.
2. Cut Out Big Bubbles
If the bubble is big, use a utility knife to cut a small “X” over it. Peel back the loose tape to see the wall underneath. Be gentle so you don’t damage the wall.
3. Add Fresh Drywall Compound
Use your putty knife to spread a thin, even layer of compound over the spot where the bubble was.
- Don’t use too much compound. A thin layer works best.
- Make sure the compound covers the area completely.
4. Put Down the Tape
If you had to remove tape, press a new strip of drywall tape onto the fresh compound. Smooth it out with your fingers to remove any air bubbles. For small bubbles, press the tape back into place using your putty knife.
5. Smooth the Surface
Use the putty knife to flatten the compound and tape. Make sure the edges blend into the wall so the repair looks smooth.
6. Let It Dry and Sand
Let the compound dry completely. This can take about 24 hours. Once it’s dry, use medium-grit sandpaper to remove any bumps. Then, use fine-grit sandpaper to make the surface smooth.
Tips to Avoid Bubbles in the Future
Fixing bubbles is important, but stopping them from happening again is even better. Here’s how you can avoid bubbles in drywall tape:
- Clean the wall first: Wipe away dust and dirt before applying compound and tape.
- Use good materials: High-quality tape and compound stick better and last longer.
- Take your time: Apply compound slowly and press the tape firmly to remove air pockets.
- Don’t rush drying: Let each layer of compound dry fully before sanding or adding more.
FAQs About Bubbles in Drywall Tape
1. Can I fix bubbles without removing the tape?
Yes, if the bubbles are small. Press them flat and cover the area with a thin layer of compound.
2. Why does drywall tape bubble after painting?
This happens if the tape wasn’t stuck down well. Moisture from the paint can make loose tape bubble.
3. How long does it take to fix drywall bubbles?
It depends on the size of the bubbles. Small repairs can take about an hour, while larger ones may take a day or two, including drying time.
Why Fixing Bubbles Matters
Bubbles in drywall tape may not seem like a big deal, but they can cause problems. They make your walls look uneven, and if left unfixed, the tape can peel away completely. This can lead to bigger repairs later. Fixing bubbles as soon as you see them will save you time and effort in the long run.
Conclusion
Fixing bubbles in drywall tape is a simple job if you follow the right steps. Start by looking at the bubbles to decide how much work is needed. Use the right tools, take your time, and smooth everything out carefully.
