When installing drywall, how should joints be butted together?

When butting drywall joints together, the proper technique is to leave a slight gap between the edges of the drywall sheets. This approach allows for the natural expansion and contraction that can occur due to temperature and humidity changes in the environment. If the joints are installed too tightly, it can lead to issues such as cracking or buckling as the materials shift.

The practice of leaving a small gap helps accommodate any movement and ensures that the joints can be properly finished with tape and joint compound without risking damage to the drywall itself. This method also helps to create a smoother, more uniform finish once the drywall is painted.

While other techniques might involve the use of adhesives, specific angles, or tight fitting, those options could introduce complications or do not address the inherent characteristics of drywall as it adjusts to its surroundings. Therefore, allowing for a loose fit at the joints is the best practice for achieving a durable and aesthetically pleasing drywall installation.
