1. Which substrate condition is most important to verify before installing
gypsum panels in a framed wall assembly?
A. The framing has been painted
B. The framing is plumb, aligned, adequately spaced, and properly secured
C. The drywall panels have been acclimated outdoors
D. The joint compound has been mixed
Answer: The framing is plumb, aligned, adequately spaced, and properly secured
Rationale: Proper framing alignment and attachment are essential because
irregular or inadequately secured framing can produce bowed walls, cracked
joints, fastener problems, and poor panel performance.
2. When installing gypsum board over wood framing, what is the primary
purpose of staggering end joints between adjacent courses?
A. To reduce the number of screws required
B. To eliminate the need for joint compound
C. To reduce the concentration of joints and improve assembly performance
D. To eliminate corner reinforcement
,Answer: To reduce the concentration of joints and improve assembly
performance
Rationale: Staggering joints reduces continuous weak planes and helps minimize
cracking and joint displacement.
3. A drywall contractor discovers that wall framing is significantly out of plane
before board installation. What is the best practice?
A. Install thinner gypsum board
B. Increase screw length
C. Correct the framing or install appropriate furring/shimming before boarding
D. Use additional joint compound
Answer: Correct the framing or install appropriate furring/shimming before
boarding
Rationale: Joint compound cannot compensate for substantial framing
irregularities. The substrate should be corrected before gypsum panels are
installed.
4. Which fastening problem is most likely to weaken the face paper of gypsum
board?
A. A screw head driven slightly below the surface without breaking the paper
B. A screw driven excessively deep through the face paper
C. A screw installed at the center of a stud
D. A screw installed perpendicular to the panel
Answer: A screw driven excessively deep through the face paper
Rationale: Breaking or crushing the face paper reduces the fastener's holding
capability and can cause nail pops, screw pops, or localized failure.
5. In a fire-resistance-rated gypsum wall assembly, why is substituting a
different gypsum board product without approval potentially serious?
,A. Different gypsum products can have different tested assembly characteristics
B. All gypsum boards have identical fire resistance
C. Thicker board always reduces fire resistance
D. Substitution only affects appearance
Answer: Different gypsum products can have different tested assembly
characteristics
Rationale: Fire-rated assemblies are tested as complete systems. Board type,
thickness, fasteners, framing, joints, insulation, and installation details can all
affect the rating.
6. What is the principal reason for installing gypsum board with the long
dimension perpendicular to wood framing when the specified assembly
calls for that orientation?
A. It always reduces waste
B. It can improve structural diaphragm behavior and distribute joints across
framing
C. It eliminates all butt joints
D. It prevents moisture absorption
Answer: It can improve structural diaphragm behavior and distribute joints
across framing
Rationale: Panel orientation can affect fastening patterns, diaphragm action,
joint locations, and overall assembly performance.
7. When should drywall joint treatment generally be performed?
A. Before the panels are securely fastened
B. After panels are properly installed and the substrate is suitable for finishing
C. Before electrical boxes are installed
D. Before framing inspection
Answer: After panels are properly installed and the substrate is suitable for
finishing
, Rationale: Joint treatment depends on stable, properly fastened panels and
suitable environmental conditions.
8. What is the primary purpose of tapered edges on standard gypsum panels?
A. To increase fire resistance automatically
B. To provide a recessed area for joint treatment
C. To eliminate fasteners
D. To prevent mold growth
Answer: To provide a recessed area for joint treatment
Rationale: Tapered edges allow tape and joint compound to be recessed so the
finished joint can be blended into the surrounding panel surface.
9. A contractor installs drywall over framing that is spaced wider than the
panel manufacturer's permitted spacing for the specified board. What is
the principal concern?
A. The board may have insufficient support and excessive deflection
B. The board will become waterproof
C. The joint compound will dry too quickly
D. The ceiling height will automatically increase
Answer: The board may have insufficient support and excessive deflection
Rationale: Gypsum panels are designed for specified framing spacing. Excessive
spacing can cause sagging, cracking, or failure.
10.What is the best method for cutting a gypsum panel when a clean straight
cut is required?
A. Score the face paper, snap the panel, and cut the back paper
B. Cut only the back paper
C. Bend the panel until it breaks without scoring
D. Saturate the panel with water
Answer: Score the face paper, snap the panel, and cut the back paper
