1. Before installing resilient flooring over a concrete slab, which condition is
MOST important to verify?
A. The slab has a smooth appearance
B. The slab is at least 4 inches thick
C. The substrate meets the flooring manufacturer's moisture and alkalinity
requirements
D. The concrete contains no visible aggregate
Answer: The substrate meets the flooring manufacturer's moisture and
alkalinity requirements
Rationale: Moisture and alkalinity can cause adhesive failure, bubbling,
discoloration, mold growth, or flooring deterioration. Manufacturer
requirements must be satisfied before installation.
2. A concrete slab has excessive surface moisture and the flooring manufacturer
prohibits installation above a specified moisture level. What is the proper
action?
A. Add additional adhesive
B. Install a vapor barrier over the flooring
,C. Delay installation until acceptable conditions are achieved or use an approved
mitigation system
D. Apply primer and immediately install flooring
Answer: Delay installation until acceptable conditions are achieved or use an
approved mitigation system
Rationale: Excessive moisture cannot normally be corrected by simply adding
adhesive. The flooring system must be installed only when the substrate meets
specified conditions or an approved mitigation system is used.
3. What is the primary purpose of floor patching compound before resilient
flooring installation?
A. Increase structural capacity
B. Correct minor surface irregularities and provide a suitable installation surface
C. Waterproof the entire slab
D. Replace the concrete substrate
Answer: Correct minor surface irregularities and provide a suitable installation
surface
Rationale: Patch and skim materials are designed to correct minor
imperfections. They are not substitutes for structural repairs or complete
waterproofing systems.
4. Which substrate condition is MOST likely to telegraph through sheet vinyl?
A. Properly cured concrete
B. Smooth plywood
C. Existing ridges, joints, depressions, or other surface irregularities
D. Properly installed underlayment
Answer: Existing ridges, joints, depressions, or other surface irregularities
Rationale: Resilient flooring can reveal imperfections beneath it, particularly
when the substrate is not properly leveled or smoothed.
,5. When installing flooring over plywood underlayment, why is panel
orientation important?
A. It determines paint color
B. It can influence stiffness, joint location, and dimensional stability
C. It determines adhesive cure time
D. It eliminates the need for fasteners
Answer: It can influence stiffness, joint location, and dimensional stability
Rationale: Proper panel orientation and installation reduce movement and help
create a stable surface for finished flooring.
6. A flooring contractor discovers a plywood subfloor has significant deflection
between joists. What should occur before installing brittle tile?
A. Use more grout
B. Increase adhesive thickness
C. Correct the structural or substrate-deflection problem
D. Install tile directly over the plywood
Answer: Correct the structural or substrate-deflection problem
Rationale: Tile systems are sensitive to movement. Excessive deflection can
result in cracked tile, cracked grout, bond failure, and premature failure.
7. What is the primary function of an approved tile underlayment or uncoupling
membrane?
A. Eliminate every type of structural movement
B. Provide a suitable interface between the substrate and tile assembly
C. Replace all waterproofing requirements
D. Increase tile color consistency
Answer: Provide a suitable interface between the substrate and tile assembly
, Rationale: Depending on the product, membranes can provide crack isolation,
uncoupling, waterproofing, or other functions. They must be installed according
to their specific listing and instructions.
8. Which condition is most concerning when installing wood flooring over
concrete?
A. Concrete color
B. Moisture vapor transmission
C. Aggregate size alone
D. Slab appearance
Answer: Moisture vapor transmission
Rationale: Excessive moisture can cause wood to cup, crown, swell, buckle,
delaminate, or develop adhesive failure.
9. Why should flooring materials generally be acclimated according to
manufacturer instructions?
A. To change their color
B. To allow material temperature and moisture conditions to reach installation
requirements
C. To remove factory markings
D. To increase adhesive strength
Answer: To allow material temperature and moisture conditions to reach
installation requirements
Rationale: Wood and some other flooring materials respond to temperature and
humidity. Proper acclimation reduces dimensional movement after installation.
10. A wood floor is installed when the indoor relative humidity is substantially
different from the expected normal operating range. What is a major risk?
A. Improved dimensional stability
B. Excessive dimensional movement after occupancy
