How are drywall sheets typically fastened to a wall?

Fastening drywall sheets to a wall is primarily accomplished with drywall screws or nails. This method is favored because screws provide a stronger hold compared to other fasteners, minimizing the likelihood of the sheets pulling away from the framing over time. Drywall screws have a specialized thread design that allows them to grip into the gypsum core of the drywall and the wooden or metal studs behind it, ensuring a tight and secure installation.

While adhesive can be used in conjunction with screws or nails to reduce the number of fasteners needed, relying solely on adhesive would not ensure the same level of security and stability, especially in areas subject to movement or flexing.

Additionally, staples may not provide a sufficient hold, as they can easily pull out of the drywall under stress. On the other hand, tape and joint compound are essential for finishing seams between drywall sheets after they are installed, but they do not serve the purpose of fastening the sheets to the wall structure.
