Is it OK to use mesh tape for drywall?

Mesh tape is a common option for finishing drywall seams and corners. It offers some advantages over paper drywall tape, but also has some potential drawbacks. Here is a look at whether mesh tape is a good choice for your drywall project.

What is Mesh Tape?

Mesh tape for drywall is a self-adhesive fiberglass or polymer mesh that is used to finish drywall seams and corners. It comes in various widths for seam and corner applications. Mesh tape is coated with a pressure-sensitive adhesive that bonds it to the wall surface.

Most mesh tape has an open weave that allows joint compound to penetrate through the holes in the mesh. This creates excellent adhesion and allows finishing in less time than paper tape. Mesh is not paper-based like traditional drywall tape.

Advantages of Mesh Tape

Here are some of the benefits of choosing mesh over paper drywall tape:

• Thinner application: Mesh tape requires less joint compound than paper tape.
• Faster drying: The joint compound dries quicker through the mesh holes.
• Prevents cracks: The fiberglass mesh is more flexible and less prone to cracking.
• Easier finishing: Mesh tape eliminates air bubbles and wrinkles in the tape.
• Stronger joints: The mesh embeds into the compound for stronger seams.

The thinness and strength of mesh tape can make finishing seams much easier and faster than with paper tape. In many cases, joints can be completed in just two coats rather than three.

Potential Drawbacks

Despite its advantages, mesh tape also has some disadvantages to consider:

• More expensive: Mesh tape costs more per foot than paper tape.
• Visible seams: The mesh can show through finished joints more than paper.
• Trickier with lightweight spackle: Lightweight spackle may not fully penetrate the mesh.
• Harder to work with for amateurs: Paper tape is more forgiving for beginners.

The transparency of mesh can make it harder to create an invisible seam. It also requires some skill to fully embed it into the joint compound. Novices may find paper tape easier to work with.

Best Practices for Using Mesh Tape

If you decide to use mesh tape, follow these tips for success:

• Only use fiberglass mesh, not plastic. Plastic mesh is too flimsy.
• Apply a thin layer of joint compound under the tape to maximize adhesion.
• Forcefully embed the mesh into the compound with a taping knife.
• Use a setting-type compound for the first two coats.
• Apply multiple thin coats rather than one thick coat.
• Sand lightly between coats when dry.
• Use a high-quality finishing compound for the final coat.

The key is to fully embed the mesh into a setting-type joint compound and build up thin, smooth coats. Allow each layer to dry fully before applying the next.

Where to Use Mesh Tape

Mesh tape performs best for finishing the following:

• Flat drywall seams between panels
• Outside corners
• Repairing damaged drywall

It can also be effective for finishing inside corners, though paper tape may create a more seamless look. Mesh is also not ideal for areas that require highly smooth finishes, like walls that will be painted with a gloss sheen.

Mesh vs. Paper Tape Comparison

Here is a table comparing some of the key differences between mesh and paper drywall tape:

Criteria	Mesh Tape	Paper Tape
Material	Fiberglass or polymer mesh	Paper
Adhesion	Self-adhesive coating	Embedded in compound
Joint strength	Very strong	Strong
Crack resistance	Excellent	Good
Seam visibility	More visible	Less visible
Coats needed	2-3 thin coats	3-4 coats
Ideal for…	Corners, repairs, fast finishing	Smooth finishes, inside corners
Cost	More expensive	Less expensive

Conclusion

Mesh tape offers a very strong, crack-resistant seam that finishes faster than paper tape. However, it may be more visible and takes some skill to work with. Novices may have an easier time with paper tape to achieve an invisible finish.

Mesh is ideal for outside corners, flat joints between panels, and drywall repairs. It bonds tightly and adds strength. But paper tape may still be preferable for inside corners and where smooth finishing is needed. Consider the advantages and disadvantages before deciding on which option is right for your next drywall project.

Frequently Asked Questions

Is mesh tape better than paper?

Mesh tape creates a very strong bond and can prevent cracks from forming in joints. However, paper tape may result in a more seamless finish and requires less skill to work with. There are advantages to both options.

When should you avoid mesh tape?

Avoid mesh tape for textured finishes and areas that require an ultra-smooth surface, like semigloss painted walls. The mesh pattern may show through the texture. Paper tape is better for these applications.

Does mesh tape need 3 coats?

With mesh tape, you can often get away with just two coats if you fully embed the mesh into the first layer of setting-type joint compound. Apply multiple thin coats rather than one thick coat.

Is it harder to put up mesh tape?

Mesh tape requires some skill to fully embed into the joint compound. Novices may find it lays flatter and works better than paper tape. But with practice, mesh tape can create very strong seams with fewer coats.

Can you use all purpose compound with mesh tape?

It’s best to use a setting-type compound when embedding mesh tape. Lightweight all purpose compounds may not fully penetrate and bond with the mesh. Use all purpose for the finish coat.

Does mesh tape bubble when it dries?

Bubbling can occur if the mesh tape is not fully embedded into the compound. Be sure to force it into the joint compound with a taping knife. Apply thin, even layers allowing each coat to fully dry.

Is fiberglass mesh tape waterproof?

Fiberglass mesh is not waterproof on its own. But when fully embedded into joint compound, it forms a waterproof bond. The compound seals and protects the mesh tape from moisture.

Can you use mesh tape on corners?

Yes, mesh tape sticks well to corners and provides added strength. Fold the tape evenly along the corner before applying compound over it. For inside corners, paper may be less visible.

How do you finish mesh tape smoothly?

Build up thin, even coats allowing each layer to fully dry. Lightly sand between coats and use a high-quality finishing compound for the final coat. Don’t apply one thick layer that may shrink unevenly.

Choosing the Right Drywall Tape

Both mesh and paper tapes have their advantages for finishing drywall seams and corners. Consider where the tape will be used, the desired final appearance, your skill level, and cost when deciding on which option to use. Mesh requires some experience to work with but creates very strong joints that resist cracking. Paper offers a more foolproof application for novices and disappears better on inside corners. Weigh the pros and cons of each before choosing the right drywall tape for your project.

Tips for Applying Mesh Tape

Applying mesh tape takes some finesse. Follow these tips to make the job easier and achieve better results:

• Cut mesh tape with standard scissors rather than tearing by hand for clean edges.
• For seams, place mesh tape centered over the joint and pull taut for a flat application.
• Always use a setting-type compound for embedding the first layer. All-purpose may not fully penetrate the mesh.
• Force the mesh into the compound by pressing firmly with a taping knife.
• Fold mesh tape neatly along corners without overlapping then press into place.
• Apply compound in thin, even coats. Thick coats take longer to dry and shrink unevenly.
• Feather out edges of the compound to taper seams for a smooth finish.
• Lightly sand each coat when fully dry before applying the next layer.

Proper mesh tape application takes practice. Work methodically, embed fully into setting compound, and build up multiple thin, smooth coats for best results.

Common Problems With Mesh Tape

Mesh tape simplifies drywall finishing in many ways but also comes with some potential problems. Here are solutions to some of the most common mesh tape issues:

• Bubbles or blisters – Caused by not forcing the mesh into the compound enough. Re-apply pressure with a taping knife.
• Visible seams – Build up to a thicker total depth and feather edges wider.
• Cracking – Apply thinner coats, allow proper drying time between layers.
• Peeling – Ensure first layer is setting-type compound and mesh is fully embedded.
• Mesh showing through – Add additional thin finish coats until fully concealed.
• Uneven drying – Avoid applying one thick layer that dries unevenly. Use multiple thinner coats.

With practice and the right techniques, mesh tape can deliver hassle-free, crack-proof seams. Learn how to address any issues that arise to achieve professional-looking results.

Mesh vs. Fiberglass Drywall Tape

In addition to paper tape, fiberglass tape is another common option for drywall finishing. This type of tape is similar to mesh but lacks the grid pattern. Here is a brief comparison:

• Fiberglass tape – Made of fiberglass matting that embeds into compound. More sheer appearance.
• Mesh tape – Woven mesh grid pattern. Allows compound to adhere through openings.
• Strength – Both create very strong joints less prone to cracking.
• Seams – Fiberglass tape can be less visible on finished seams.
• Corners – Mesh grips better on corners.
• Ease of use – Mesh tape has self-stick adhesive making application easier.

Overall, mesh and fiberglass tapes have more similarities than differences. Mesh may have a slight edge for DIY use thanks to its self-adhesive property. But either offers stronger, longer-lasting joints than paper tape alone.

Transitioning From Paper to Mesh Tape

If you’re used to working with paper tape, switching to mesh can take some adjustment. Follow these tips to master the transition:

• Practice first on scraps or in inconspicuous areas to hone technique.
• Use scissors for clean cuts rather than tearing mesh by hand.
• Fold mesh tape evenly into corners without overlapping excessively.
• Press mesh firmly into setting compound with even pressure from a taping knife.
• Apply multiple thinner coats vs. one thick application.
• Build to a thicker overall depth and feather out wider to hide seams.
• Lightly sand each coat when dry to smooth the finish.
• Allow full drying time between applications.

It may take a project or two to adapt to mesh tape. But once mastered, the strength and time savings will become clear benefits. Be patient, use proper techniques, and mesh can help take your drywall finishing to the next level.
