What is the primary distinction between taping and finishing in drywall installation?

1. Taping involves applying joint compound

2. Taping refers to applying tape to joints

3. Finishing includes only sanding

4. Finishing is done before taping

The correct answer is: Taping refers to applying tape to joints

The primary distinction between taping and finishing in drywall installation lies in the process involved with each step. Taping specifically refers to the application of tape to the joints between drywall sheets. This process is critical as it helps to bridge the gaps and reinforces the joints, minimizing the risk of cracks. After taping, the joint compound is applied over the tape to create a smooth surface, but the act of taping itself is distinct in that it focuses solely on the placement of tape. In contrast, finishing encompasses a broader set of activities, including the application of joint compound over the taped joints, followed by sanding and ensuring that the surface is smooth and ready for painting or further treatment. While both processes are integral to proper drywall installation, taping is a specific action aimed at securing and sealing joints, while finishing is the overall process of achieving a polished look.
