What technique is commonly recommended for joining two pieces of drywall on a horizontal seam?

Aligning the seams in a straight line
Staggering the seams to distribute stress
Overlapping the seams for added strength
Leaving a gap between the seams

The correct answer is: Staggering the seams to distribute stress

Staggering the seams when joining two pieces of drywall on a horizontal seam is recommended because it helps to distribute stress more evenly across the surface. This technique minimizes the risk of cracking or failure because when seams are aligned in a straight line, they can create a weak point that is more susceptible to movement or pressure. By staggering the seams, the points where the drywall is joined are offset, which allows for better structural integrity. This approach ensures that the drywall panels are held together more securely and helps in maintaining a flat, even surface once finishing is applied. Overall, staggering seams is a best practice that contributes to the durability and longevity of the drywall installation.
