rationales provide detailed explanations to help you understand the “why”
behind each correct answer. Use this guide to identify weak areas, review the
cited sources, and build confidence for the NYCHA Supervisor Painter written
exam.
PART 1: PAINT MATERIALS & COATINGS (Questions 1–100)
1. Which paint type provides the best resistance to repeated scrubbing in NYCHA
hallways?
A) Flat latex
B) Eggshell acrylic
C) Semi-gloss latex
D) Chalk paint
Answer: C
Rationale: Semi-gloss latex is durable, washable, and resists scuffing, making it
ideal for high-traffic NYCHA hallways. Flat paint shows marks easily and is not
washable. Eggshell is slightly more washable than flat but less scrubbable than
semi-gloss. Chalk paint is decorative, not durable, and would wear off quickly.
2. What is the primary binder in latex paint?
, A) Linseed oil
B) Alkyd resin
C) Acrylic or vinyl resin
D) Epoxy
Answer: C
Rationale: Latex paints are water-based and use acrylic or vinyl resins as binders.
Linseed oil and alkyd are binders in oil-based paints. Epoxy is a separate chemical
family used for two-part coatings.
3. You need to paint a NYCHA basement floor that receives light foot traffic. Best
choice?
A) Flat latex wall paint
B) Epoxy paint or porch-and-floor enamel
C) Chalk paint
D) Acrylic craft paint
Answer: B
Rationale: Basement floors require durable, abrasion-resistant coatings. Epoxy
paint forms a hard, chemical-resistant film that withstands foot and light rolling
traffic. Porch-and-floor enamel is another acceptable option specifically
formulated for foot traffic. Wall paints are too soft and would wear quickly.
4. A NYCHA resident reports paint peeling in a bathroom. Most likely cause?
A) Used primer
B) High humidity without moisture-resistant paint
C) Too many coats applied
D) Synthetic brush was used
,Answer: B
Rationale: Bathrooms have high humidity from showers. Standard flat or low-
sheen paints absorb moisture, leading to adhesion failure and peeling. Moisture-
resistant paint (semi-gloss, satin, or bathroom-specific formulas) is required.
Primer alone does not prevent humidity damage.
5. Which primer is best for covering water stains on a NYCHA ceiling?
A) Latex primer
B) Shellac-based primer
C) Oil-based primer
D) Bonding primer
Answer: B
Rationale: Shellac-based primers provide the strongest stain-blocking properties,
effectively sealing water, nicotine, smoke, and other stubborn stains. Water-
based primers often allow stains to bleed through. Oil-based primers work
moderately well but are inferior to shellac for severe stains.
6. What is the VOC limit for compliant paint used inside NYCHA buildings (per NYC
Local Law 47)?
A) 50 g/L
B) 100 g/L for flat, 150 g/L for non-flat
C) 250 g/L
D) 500 g/L
Answer: B
Rationale: NYC Local Law 47 restricts VOCs in architectural coatings: 100 g/L for
flat paints, 150 g/L for non-flat (eggshell, satin, semi-gloss, gloss). Higher VOC
paints cannot be used in NYCHA buildings indoors. This regulation reduces indoor
air pollution and health risks to residents and workers.
, 7. You specify paint for radiators. Which is correct?
A) Latex wall paint
B) High-heat enamel (200°F+)
C) Epoxy floor paint
D) Acrylic craft paint
Answer: B
Rationale: Radiators reach high surface temperatures (140–200°F+). Standard
paints soften, yellow, emit odors, or peel. High-heat enamel is specially
formulated to withstand these temperatures without degradation, maintaining
adhesion and color.
8. Which gloss level provides the highest durability and easiest cleaning for trim
and doors?
A) Flat
B) Eggshell
C) Satin
D) High-gloss
Answer: D
Rationale: High-gloss paint has the highest sheen and hardest film, making it the
most durable and easiest to clean. It resists scuffs, stains, and moisture
penetration. Flat and eggshell are too soft and porous for trim and doors that
receive frequent touching and cleaning.
9. What is the hiding power measurement unit for paint?
A) Viscosity (cP)
B) Spreading rate (sq ft/gal)
