What is a key advantage of using self-adhesive mesh tape in drywall work?

1. It provides better adhesion

2. It eliminates the need for a layer of joint compound beneath the tape

3. It reduces drying time

4. It reinforces the drywall structure

The correct answer is: It eliminates the need for a layer of joint compound beneath the tape

Using self-adhesive mesh tape has a significant advantage in that it eliminates the need for a layer of joint compound beneath the tape. This self-adhesive feature allows it to stick directly to the drywall surface, which can speed up the application process. Since it adheres directly without needing a preliminary coat of joint compound, it simplifies the installation steps and can save time on the job site. This characteristic also means that the tape is able to bond well to the drywall, providing a reliable surface for finishing while promoting a smoother overall appearance when joint compound is applied over it. This allows for efficient layering in the finishing process, contributing to better final results in less time. While the other options present benefits that may pertain to different aspects of drywall finishing, they do not fully encapsulate the primary advantage of self-adhesive mesh tape in the context of its application.
