2026 Q&A | Guaranteed Pass
(GRADED A+)
Question 1
what is the minimum recommended acclimation period for
hardwood flooring?
A. 1 hour
B. 12 hours
C. 24–72 hours
D. 7 days
Answer: C. 24–72 hours
Rationale: Allowing the material to adjust to the environment
prevents future expansion, contraction, or buckling .
Question 2
What is the primary cause of hardwood floor cupping?
A. Low humidity
B. Excess moisture from below
C. Too much glue
D. High lighting exposure
,Answer: B. Excess moisture from below
Rationale: Moisture from the subfloor causes the edges of
hardwood boards to lift higher than the center .
Question 3
What is the main purpose of expansion gaps in flooring
installation?
A. Improve design
B. Allow material movement
C. Reduce cost
D. Increase hardness
Answer: B. Allow material movement
Rationale: Expansion gaps accommodate natural expansion and
contraction due to temperature and humidity changes, preventing
buckling .
Question 4
Which tool is used to spread adhesive evenly?
A. Paint roller
B. Notched trowel
C. Scraper
D. Chalk line
Answer: B. Notched trowel
Rationale: A notched trowel ensures consistent adhesive thickness
and proper coverage for secure flooring bonding .
Question 5
What should be done with loose, cracked, contaminated, or
unsound substrate material?
A. Cover it with flooring
,B. Remove or properly repair it before installation
C. Paint over it
D. Add wax
Answer: B. Remove or properly repair it before installation
Rationale: The flooring system depends on the integrity of the
substrate; unsound material can cause failure of the finished
installation .
Question 6
What is the purpose of a vapor barrier?
A. Improve appearance
B. Block moisture migration
C. Increase hardness
D. Reduce cost
Answer: B. Block moisture migration
Rationale: Vapor barriers help control moisture migration from
the substrate, which is critical for preventing damage to flooring
materials .
Question 7
Which safety equipment is essential when cutting flooring
materials?
A. Sunglasses
B. Ear protection and safety goggles
C. Gloves only
D. Hard hat only
Answer: B. Ear protection and safety goggles
Rationale: Cutting tools produce noise and debris, so eye and ear
protection is critical to prevent injury .
, Question 8
What is the purpose of floor leveling compound?
A. Add color
B. Smooth uneven subfloors
C. Increase hardness
D. Reduce noise only
Answer: B. Smooth uneven subfloors
Rationale: Leveling compounds correct surface irregularities to
ensure proper flooring installation and performance .
Question 9
What happens if flooring is installed without acclimation?
A. Better adhesion
B. Material instability
C. Faster curing
D. Lower cost
Answer: B. Material instability
Rationale: Without acclimation, flooring materials may expand or
contract after installation, causing gaps or buckling .
Question 10
What is the purpose of a moisture meter?
A. Measure temperature
B. Detect subfloor moisture levels
C. Measure thickness
D. Check alignment
Answer: B. Detect subfloor moisture levels
Rationale: Moisture meters are used to test subfloor moisture
content before installation .
