Drywall tape bubbles are like that annoying friend who always shows up uninvited – they’re a frustrating and unsightly issue that can ruin the look of your freshly painted walls. Whether you’re a seasoned DIY-er or a novice homeowner, encountering drywall tape bubbles is inevitable. But fear not, for in this article, we’ll walk you through the steps to fix bubbles in drywall tape and provide tips to prevent them from reappearing.
Drywall tape bubbles can occur for a few different reasons. One common cause is poor installation.
Bubbles can form if the tape is not applied correctly or if the air is trapped behind it.
Another cause could be excess moisture in the wall, which can cause the tape to lift and bubble.
Finally, if the drywall was not properly sealed or primed before the tape was applied, this can also cause bubbles.
To fix drywall tape bubbles, you must remove the affected area of tape and reapply it properly.
First, use a utility knife to cut away any loose or bubbled tape sections carefully.
Next, apply a thin layer of joint compound over the area where the tape was removed.
Then, apply a new piece of drywall tape, press it firmly into place, and smooth out any bubbles or wrinkles.
Finally, apply another thin layer of joint compound over the tape, feathering it out to blend into the surrounding wall.
Once the joint compound is dry, you can sand it down and paint over it as needed.
So let’s pop those bubbles and start restoring your walls to their former smoothness!
Drywall Tape Bubbles: What Causes Them and How to Fix Them
Drywall tape bubbles are a frustrating and unsightly issue that can occur due to various reasons.
While they may seem like a small cosmetic problem, they can ultimately lead to larger issues if left unaddressed, such as the tape lifting away from the joint and allowing moisture to seep in, leading to mold growth and other damage.
What Causes Drywall Tape Bubbles?
- Poor installation techniques: If the drywall tape is not properly centered over the joint or smoothed out properly during installation, it can cause bubbles underneath the tape.
- Insufficient joint compound application: If not enough joint compound is applied to fill the gap between the drywall sheets, it can create air pockets or bubbles underneath the tape.
- Excess moisture: If the drywall is not allowed to dry completely before applying the tape, excess moisture can become trapped underneath the tape and cause bubbles to form.
- Low-quality tape: Using low-quality tape can cause it to lose its adhesive properties over time, causing the tape to lift and create bubbles.
- Movement or shifting: If the building experiences movement or shifting due to settling, temperature changes, or other factors, it can cause the drywall tape to lift and form bubbles.
- Improper storage: If the drywall tape is improperly stored in a humid or damp environment, it can affect the adhesive properties and cause it to lift and bubble.
- Damage to the tape: If it is damaged during installation or repair, it can cause bubbles to form as it lifts away from the joint compound.

How long does drywall tape take to dry?
The drying time for drywall tape depends on the type of joint compound used and the environmental conditions in the room.
A joint compound with drywall tape typically takes around 24 hours to dry completely. However, the drying time can vary depending on temperature, humidity, and ventilation.
In ideal conditions, where the temperature is around 70°F and the humidity is approximately 50%, the joint compound should dry within 24 hours.
However, if the temperature is cooler or the humidity is higher, it may take longer for the joint compound to dry.
It’s important to give the joint compound enough time to dry completely before sanding or applying additional layers, as this will ensure a smooth and seamless finish.
It’s also important to note that setting-type joint compound dries much faster than traditional joint compounds, typically within 1-4 hours.
However, setting-type joint compound is more difficult to sand and work with than traditional joint compound, so they may not be the best choice for all projects.
Should I overlap drywall tape?
When applying drywall tape, overlapping the tape is generally not recommended.
Overlapping the tape can create a thicker seam that may be visible after painting or finishing.
Instead, it’s best to apply the drywall tape in a slightly overlapping manner but with minimal overlap.
Typically, a 1/16-inch overlap is sufficient to reinforce the seam without creating a visible bump or ridge.
To apply the tape, start at one end of the seam and press the tape firmly into place, smoothing out any bubbles or wrinkles.
As you move along the seam, apply the tape slightly overlapping the previous piece, but avoid overlapping by more than 1/16 inch.
Once the tape is in place, apply joint compound over the tape, using a putty knife to spread the compound evenly and remove any excess.
Allow the joint compound to dry completely before sanding and adding additional layers.
By applying the drywall tape in a slightly overlapping manner, you can ensure a strong, smooth seam that will be invisible after painting or finishing.
How do you fill large gaps in drywall before taping?
When working with drywall, it’s important to properly fill any large gaps or holes before taping, as this will ensure a smooth and even surface. Here’s how to fill large gaps in drywall before taping:
- Clean the area: Use a vacuum or damp cloth to remove dust or debris from the gap or hole. This will ensure that the joint compound adheres properly.
- Apply joint compound: Fill the compound into the gap or hole using a putty knife. Make sure the joint compound is level with the surrounding drywall.
- Allow to dry: Give the joint compound enough time to dry completely. The drying time will depend on the size of the gap or hole, but it can take several hours or overnight.
- Sand the surface: Once the joint compound is completely dry, use sandpaper to smooth the surface. This will ensure the joint compound is level with the surrounding drywall and ready for taping.
- Apply drywall tape: Apply drywall tape over the gap or hole, pressing it firmly into place. Smooth out any bubbles or wrinkles.
- Apply additional layers of joint compound: Apply a thin layer of joint compound over the tape, using a putty knife to spread it evenly and remove any excess. Allow the joint compound to dry completely before sanding and adding additional layers.
By filling any large gaps or holes in drywall before taping, you can ensure a smooth and even surface that will be ready for painting or finishing.
How many layers of drywall tape do I need?
The number of layers of drywall tape you need depends on the size and depth of the joint you are trying to cover.
In most cases, two to three layers of drywall tape are sufficient to cover the joint and provide a smooth surface for finishing.
Here are some general guidelines for the number of layers of drywall tape you may need:
- For standard joints: One layer of drywall tape is usually sufficient for traditional joints where the drywall panels meet.
- For inside corners: Two layers of drywall tape are usually recommended for inside corners. Apply the first layer of tape to one side of the corner, then apply the second layer to the other side, overlapping slightly.
- For outside corners: Three layers of drywall tape are usually recommended for outer corners. Apply the first layer of tape to one side of the corner, then apply the second layer to the other side, overlapping slightly. Finally, use a third layer of tape along the center of the corner, overlapping the first two layers.
When applying multiple layers of drywall tape, allow each layer to dry completely before applying the next layer.
Apply joint compound over the tape between each layer, using a putty knife to smooth it out and remove any excess. Sand each layer lightly before applying the next layer to ensure a smooth finish.
How long after taping drywall can you paint?
The time you should wait before painting drywall after taping depends on a few factors, such as the joint compound used, humidity levels, and temperature.
Generally, waiting at least 24 hours before painting newly taped drywall is best to ensure the joint compound is completely dry and set.
However, some joint compounds may dry faster than others, and environmental conditions can also affect drying time.
It’s important to follow the manufacturer’s instructions for the joint compound you use and allow sufficient drying time before painting.
It’s also important to note that after taping and joint compound application, you may need to apply additional layers of joint compound and sanding before painting to ensure a smooth surface.
This process may require several days to complete, depending on the extent of the work.
In summary, waiting at least 24 hours after taping drywall before painting is best.
Still, it’s important to follow the manufacturer’s instructions and to allow sufficient drying time based on environmental conditions and the type of joint compound used.
Best Practices for Preventing Drywall Tape from Bubbling Again
