Which list correctly describes Gypsum Wallboard installation components?

• A. Drywall screws; tapered edges; spackle; tape
• B. Drywall screws; tapered edges; spackle; tape; plaster beads
• C. Drywall screws; rounded edges; joint compound; tape; plastic corner beads
• D. Drywall screws; tapered edges; spackle; tape; galvanized steel corner beads + spackle

Answer: (D)

Gypsum wallboard installation needs three things: secure the sheets, finish the joints, and protect the edges. Drywall screws hold the boards in place, and standard board edges are tapered so joint compound can feather smoothly over the joint with tape. The finish uses tape plus joint compound (spackle) to create a seamless surface. For corners, a corner bead is installed to provide a true, durable edge, with galvanized steel beads being a common, sturdy choice. The option that includes drywall screws, tapered edges, joint compound (spackle), tape, and galvanized steel corner beads matches all of these required components. The other choices mix in rounded edges, plaster beads, or omit corner beads, which aren’t aligned with typical gypsum wallboard installation.
