Which method can help prevent cracking in drywall joints?

Applying paint immediately after installation
Using high humidity during drying
Ensuring proper joint compound application and drying times
Using thinner joint compound

The correct answer is: Ensuring proper joint compound application and drying times

Ensuring proper joint compound application and drying times is crucial in preventing cracking in drywall joints. The application of joint compound involves multiple layers, and each layer must be applied correctly to create a smooth, even surface. If the joint compound is applied too thickly, it may not dry evenly, leading to potential cracking as it shrinks during the drying process. Additionally, allowing adequate drying times between each coat is essential; if a subsequent layer of compound is applied before the previous one has fully dried, it can result in unevenness and tension that contributes to cracking. Proper application technique includes feathering the edges of each layer and maintaining a consistent thickness, which minimizes the chance of stress concentration points that can lead to cracks. By following best practices in application and being patient with drying times, the integrity of the drywall installation is greatly enhanced, leading to a more durable finish that is less likely to develop cracks over time.
