1. During the final stage of gypsum board finishing in a Level 5 finish
application, which procedure is required to achieve the highest quality
surface preparation for gloss or semi-gloss paint applications?
A. Applying one heavy coat of texture compound over all joints
B. Installing fiberglass mesh tape over all fasteners
C. Applying a skim coat of joint compound over the entire surface
D. Sanding the board surface before taping
C. Applying a skim coat of joint compound over the entire surface
,A Level 5 finish requires a thin skim coat over the entire gypsum board
surface to minimize joint photographing and surface irregularities under
critical lighting or glossy finishes.
2. Which tool is most commonly used by drywall finishers to feather joint
compound evenly across wide butt joints?
A. Corner trowel
B. Hawk and trowel
C. Broad knife
D. Utility rasp
C. Broad knife
A broad knife allows the finisher to spread and feather joint compound
smoothly over wide seams, reducing visible transitions and creating a
uniform finish.
3. What is the primary purpose of embedding paper tape into wet joint
compound during drywall finishing?
A. To reduce paint absorption
B. To strengthen and reinforce the joint against cracking
C. To waterproof the drywall surface
D. To improve fire resistance ratings
B. To strengthen and reinforce the joint against cracking
,Paper tape bridges the gap between drywall panels and reinforces the
joint, helping prevent future cracking caused by movement or shrinkage.
4. A drywall finisher notices blistering beneath paper tape shortly after
application. What is the most likely cause?
A. Excessive sanding pressure
B. Insufficient compound beneath the tape
C. Use of setting-type compound
D. Excessive room humidity
B. Insufficient compound beneath the tape
Blistering usually occurs when insufficient joint compound is applied
beneath the tape, preventing full adhesion to the drywall surface.
5. Which sanding method best minimizes airborne dust during drywall
finishing operations?
A. Dry sanding with coarse grit paper
B. Machine grinding without vacuum extraction
C. Wet sanding with a sponge
D. Sanding immediately after compound application
C. Wet sanding with a sponge
, Wet sanding reduces airborne dust significantly because moisture captures
fine particles instead of allowing them to disperse into the air.
6. What is the recommended action if fastener heads protrude slightly
above the gypsum board surface after installation?
A. Cover them with texture spray
B. Remove the fasteners entirely
C. Drive the fasteners slightly below the surface without breaking the paper
D. Apply setting compound directly over the protrusion
C. Drive the fasteners slightly below the surface without breaking the
paper
Proper fastener seating requires dimpling the surface slightly without
tearing the paper face, ensuring adequate holding strength and a smooth
finish.
7. In drywall finishing terminology, what does “feathering” refer to?
A. Removing all dust from the joint
B. Tapering compound edges smoothly into the board surface
C. Applying decorative texture patterns
D. Embedding reinforcing mesh in corners
B. Tapering compound edges smoothly into the board surface
