Conclusionĭrywall tape is an essential part of any drywall repair job. Use the right amount of adhesive - Again, not too much and not too little. Measure and mark the joint correctly - Make sure the joint is measured and marked correctly, and that both pieces of drywall are equally and correctly marked. Apply the tape correctly - This means knowing the correct amount of time to let the adhesive set before finishing the joint, the correct way to apply the tape to the surface, and the correct distance between the tape and the surface. Use the right type of tape for the job - For example, don’t use a joint-strength tape if a light-duty tape would work just as well. Many of these issues can be prevented through proper technique and attention to detail. Tips to Prevent Drywall Tape from BubblingĪs you can see, there are a lot of ways a bubble can form in drywall tape. Bubbling caused by incorrect weather conditions may be resolved by waiting for the conditions to change. If the bubbling was caused by low humidity or temperature, it might be remedied by raising the humidity or bringing the temperature back up.
When the tape bubbles because of a surface incompatibility, you may be able to fix it by sanding the surface and applying a thin new coat of joint compound before re-taping. Sometimes bubbles form because the adhesive wasn’t given enough time to cure. The tape may have been applied too thickly or too close to the surface, or it may have been applied incorrectly. If the bubbles were caused by a problem in the application process and not a low-quality adhesive, a simple fix may be to remove the tape and try again. This can be fixed by removing all of the tape, spackling the gap where the tape was, and then re-taping and re-finishing the area.
If bubbles form in the tape, they will likely show up in the finished wall. Repair Options for Drywall Tape That Bubbles Dust or grit on the tape might scratch the drywall and cause a surface imperfection in the joint compound, causing bubbles in tape. Low humidity can also cause bubbles in tape, as can incorrect temperature and weather conditions. The thickness or type of surface may have been different than expected, resulting in the tape not being applied correctly. Bubbling can also occur when the wrong type of tape is used for the job, such as when a heavier or thicker tape is needed. It might not have been applied to the correct surface, or it might have been applied in the incorrect way. The most common culprit is a weak or low-quality adhesive that doesn’t hold the tape to the drywall. Reasons for Bubbling Tapeĭepending on the situation, drywall tape bubbles for any number of reasons. It’s sticky enough to hold the pieces of drywall together but also allows enough flexibility to allow the drywall joint to be spackled, sanded, and finished without the joint becoming too stiff and brittle. It’s very sticky, and that’s what makes it such a great and necessary product. Drywall tape is now a fiberglass mesh with a strong adhesive on both sides. Before the advent of fiberglass drywall, paper-based tape was used, but it’s now a thing of the past. Tape also prevents gaps between the pieces of drywall that could allow for leaks and pests, such as rodents, roaches, and insects, to enter the home. It’s designed to hold the joint between two pieces of drywall so that the compound can be applied and sanded to a smooth finish.
