Paper Drywall Tape

• Paper drywall tape, being non-adhesive, requires embedding in a layer of joint compound to adhere to the drywall. This process can be straightforward, but care must be taken to cover the entire surface uniformly with compound to avoid air bubbles under the tape.

• When dealing with inside corners, paper tape is preferred due to its middle crease which makes handling easier.

• Although it lacks the strength of fiberglass tape, paper tape is nonelastic, creating stronger joints. This attribute is essential for butt joints, often considered the weakest points in drywall installations.

• It is versatile as it can be used with both drying-type and setting-type compounds.

Cost: $1.55 per 250-ft. roll

Fiberglass-Mesh Drywall Tape

• Fiberglass-mesh tape is self-adhesive, which eliminates the need for an embedding layer of compound. This accelerates the taping process and ensures the tape lays flat on the drywall surface. Additionally, it allows for taping all room seams before applying the first coat of compound.

• Despite being stronger than paper tape in ultimate load, its higher elasticity makes it more susceptible to developing cracks.

• It is recommended to cover mesh tape with a setting-type compound, as it is stronger and can counterbalance the tape's elasticity. Following the initial coat, either type of compound can be used.

• For patching areas where joint strength is less critical, mesh tape allows for quicker repairs.

• While manufacturers approve using paper tape with paperless drywall, mesh tape offers the finest protection against mold.

• In scenarios with inside-corner gaps wider than 1/4-inch, using mesh tape and a layer of compound to fill the gap creates a solid base for finishing the corner with paper tape. For airtight drywall installations, ensure the gap is filled with foam before finishing.

Cost: $4.85 per 150-ft. roll

In my experience of over 30 years in the drywall industry, and running my own business for 15 of those years, I have consistently found mesh tape to be the best choice for drywall repairs. Like many aspects of drywall work, the effectiveness of mesh tape depends on your skill and understanding of the material.

The major advantage of mesh tape is that it speeds up the taping process. You can apply it directly to the joint and coat it immediately, reaching the taped and coated stage much faster than with paper tape. When using fast-setting joint compound, also known as hot mud, you benefit from minimal shrinkage and the ability to apply multiple coats in a single day. Additionally, hot mud virtually eliminates the blistering issues that often plague amateurs.

With extensive experience, I've never had a call back due to tape failure or joint cracks, which speaks volumes about the reliability of mesh tape when applied correctly. For those new to drywall, a bit of extra effort can achieve satisfactory results.
