EPOXY FLOOR SYSTEMS – FUNDAMENTALS & SUBSTRATE
REQUIREMENTS
Q4. What is the primary purpose of an epoxy floor system in industrial and
commercial environments?
A) To provide temporary floor covering
B) To increase aesthetic value only
C) To create a durable, chemical-resistant surface that protects the underlying substrate
D) To reduce floor thickness
Correct Answer: C
Rationale: Epoxy flooring systems are primarily designed to provide a highly durable,
seamless, and chemical-resistant surface that protects the underlying substrate and
withstands heavy use.
,Q5. Which substrate is most suitable for epoxy floor installation?
A) Wood
B) Concrete
C) Asphalt
D) Tile
Correct Answer: B
Rationale: Epoxy adheres best to clean, cured concrete surfaces. Concrete provides the
necessary strength and porosity for proper mechanical bonding when correctly
prepared.
Q6. Before applying epoxy, concrete must be:
A) Painted
B) Cleaned, dry, and free of contaminants
C) Wet
D) Polished with wax
Correct Answer: B
Rationale: Surface preparation is critical; contaminants such as oil, grease, dust, and
curing compounds can prevent adhesion and cause coating failure.
Q7. What is the typical curing time for a standard 2-part epoxy floor at 25°C
(77°F)?
A) 2 hours
B) 6 hours
C) 24–72 hours
D) 7 days
Correct Answer: C
Rationale: Epoxy curing depends on temperature and humidity; standard systems
usually cure within 1–3 days (24–72 hours).
, Q8. Which method is best for testing concrete moisture before epoxy application?
A) Visual inspection
B) Hammer test
C) Calcium chloride test (ASTM F1869)
D) pH paper
Correct Answer: C
Rationale: Moisture vapor emission can cause epoxy delamination; the calcium chloride
test is the standard method for measuring moisture vapor emission rates.
Q9. What is the main hazard associated with epoxy resins?
A) Fire
B) Skin and respiratory irritation
C) Electrocution
D) Noise
Correct Answer: B
Rationale: Epoxy resins and hardeners can cause skin sensitization and respiratory
issues; proper PPE (gloves, respirators, eye protection) is necessary.
Q10. Which surface profile is recommended for epoxy adhesion on new concrete?
A) Smooth troweled finish
B) ICRI CSP 2–4 (slightly roughened)
C) CSP 0 (as-cast)
D) Glass-like finish
Correct Answer: B
