Drywall Materials and Installation 12 items
Our study plan for this topic: Gypsum panel product types and specifications; Framing requirements for drywall systems; Fastener types, spacing, and attachment methods; Single-layer and double-layer application techniques; Joint treatment and finishing procedures; Fire-resistance-rated assemblies and UL-listed designs; Backerboard installation for wet areas; Common drywall defects, causes, and remedies.
Taping and Finishing 4 items
Special Applications Including Veneer Plaster 3 items
OSHA Safety 3 items
Sample 1 — Drywall Materials and Installation
Question: You are a contractor framing a non-load-bearing interior partition using 25-gauge steel studs. You need to attach the steel runners to a concrete floor. Which of the following fastening methods is appropriate for securing runners to concrete?
- A. 3/8" Type S-12 pan head screws
- B. 1-1/4" Type W screws
- C. Stub nails or power-driven fasteners
- D. Toggle bolts
Correct Answer: C
According to the Gypsum Construction Handbook, runners are securely attached to concrete and masonry using stub nails or power-driven fasteners. Toggle bolts are specified for suspended ceilings, Type W screws for wood framing, and Type S-12 pan head screws for foam-backed metal concrete inserts.

Sample 2 — Ceilings, Acoustical Systems Materials and Installation
Question: Suspended ceilings in seismic design categories D, E and F normally call for 2-inch wall molding. Alternate designs using seismic accessories such as ACM7 clips permit wall molding of what narrower width?
- A. 1/2″
- B. 1-1/4″
- C. 1-1/2″
- D. 7/8″
Correct Answer: D
Alternate seismic design solutions allow preferred aesthetic details such as 7/8″ wall molding in place of 2″ wall molding in seismic categories D, E and F, with performance achieved through accessories including ACM7 seismic clips and four-way seismic expansion joint clips.

Sample 3 — Taping and Finishing
Question: You are a carpenter installing drywall in a large open-plan office. The architect is concerned about potential cracking due to thermal and hygrometric expansion along the long partition runs. What installation measure should you recommend to relieve stress and minimize cracking in these areas?
- A. Use thicker drywall panels throughout the entire partition
- B. Increase the number of fasteners at each stud location
- C. Install control joints for relief in long partition runs and large ceiling areas
- D. Apply additional layers of joint compound over all joints
Correct Answer: C
According to the Gypsum Construction Handbook, excessive stresses from hygrometric and/or thermal expansion and contraction can cause joint and field cracking. The recommended prevention is to correct improper job conditions and install control joints for relief in long partition runs and large ceiling areas.
