Question 1
Which gypsum board type is generally used for standard interior wall
and ceiling applications in dry areas?
a. Type X gypsum board
b. Cement board
c. Regular gypsum board
d. Exterior sheathing board
Rationale: Regular gypsum board is designed for ordinary interior
applications where enhanced fire resistance or moisture resistance is
not required. Type X is selected when a fire-resistance rating is
needed, while cement board is typically used in wet or high-moisture
areas.
Question 2
,What is the primary purpose of gypsum board joint tape?
a. Increase insulation value
b. Reinforce the joint and prevent cracking
c. Improve sound transmission
d. Replace fasteners
Rationale: Joint tape reinforces the seam between gypsum panels and
helps prevent cracking as the assembly experiences normal
movement. It is embedded in joint compound to create a continuous
finished surface.
Question 3
Which fastener is normally appropriate for attaching gypsum board to
wood framing?
a. Roofing nails
b. Masonry anchors
c. Drywall screws designed for wood framing
d. Concrete wedge anchors
Rationale: Drywall screws designed for wood framing provide
appropriate holding power and can be installed with controlled depth.
Roofing nails and masonry anchors are not intended for typical
gypsum-board-to-wood framing connections.
,Question 4
Why should drywall screws be installed slightly below the face of the
gypsum board?
a. To expose the paper core
b. To create ventilation holes
c. To allow joint compound to cover the screw head without
damaging the face excessively
d. To make the board thinner
Rationale: A properly driven screw creates a shallow dimple that can
be filled with joint compound. Driving the screw too deeply can break
the face paper and reduce the fastener's holding ability.
Question 5
What is a major concern when a drywall screw breaks through the
gypsum board paper?
a. Increased fire rating
b. Improved joint strength
c. Reduced holding power of the fastener
d. Better surface appearance
, Rationale: The paper facing contributes significantly to the board's
ability to hold a screw. Overdriving can tear the paper and allow the
fastener to lose its effective grip.
Question 6
What tool is commonly used to cut gypsum board along a straight line?
a. Pipe wrench
b. Utility knife
c. Adjustable wrench
d. Torpedo level
Rationale: A utility knife can score the face paper and gypsum core,
after which the panel can be snapped along the scored line. The back
paper is then cut to separate the piece.
Question 7
What is the purpose of staggering drywall joints between adjacent
rows?
a. Reduce the number of studs
b. Eliminate all fasteners
c. Reduce the concentration of joints and improve the finished
assembly
d. Increase panel thickness
