SECTION 1: PAINT TECHNOLOGY & MATERIAL SELECTION (Questions 1-25)
**Question 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) Semi-gloss latex
**Rationale:** Semi-gloss latex forms a hard, durable film that withstands frequent washing and
resists scuffing. Flat paint absorbs dirt and shows marks easily; eggshell is less scrubbable;
chalk paint is not durable for high-traffic areas .
---
**Question 2**
What is the primary binder in high-quality latex paint used by NYCHA?
A) Linseed oil
B) Alkyd resin
C) Acrylic resin
,D) Epoxy
**Answer:** C) Acrylic resin
**Rationale:** Acrylic resin provides superior durability, UV resistance, and flexibility compared
to vinyl. Latex paints use water-based acrylic/vinyl binders. Linseed oil and alkyd are oil-based;
epoxy is a separate chemical family .

**Question 3**
What is the VOC limit for compliant flat paint used inside NYCHA buildings (per NYC Local Law
47)?
A) 50 g/L
B) 100 g/L
C) 250 g/L
D) 500 g/L
**Answer:** B) 100 g/L
**Rationale:** Local Law 47 limits VOCs to 100 g/L for flat paint and 150 g/L for non-flat (eggshell,
satin, semi-gloss). 250/500 g/L exceed legal limits .

**Question 4**
You need to specify paint for a NYCHA radiator. Which coating is correct?
A) Interior latex wall paint
B) High-heat enamel (rated 200°F+)
,C) Epoxy floor paint
D) Acrylic craft paint
**Answer:** B) High-heat enamel (rated 200°F+)
**Rationale:** Radiator surface temperatures can reach 180-200°F. Standard wall paint will
yellow, become brittle, or peel. High-heat enamel is formulated to withstand thermal expansion .
---
**Question 5**
Which paint sheen is MOST effective at hiding surface imperfections like dents and poorly sanded
patches?
A) High-gloss
B) Semi-gloss
C) Satin
D) Flat
**Answer:** D) Flat
**Rationale:** Flat paint scatters light, minimizing bumps and valleys. Glossy finishes reflect
light and highlight every defect. Flat is preferred for ceilings and imperfect walls .
---
**Question 6**
Which primer is essential for covering severe water stains on a NYCHA ceiling (e.g., from a
leaking roof)?
A) Latex primer
, B) Shellac-based primer
C) PVA primer
D) Bonding primer
**Answer:** B) Shellac-based primer
**Rationale:** Shellac primer is the only universal sealer that completely blocks tannin and water
stains without bleeding through. Oil-based may work, but shellac is superior for severe stains .
---
**Question 7**
You need to paint a NYCHA basement floor that receives light foot traffic. What is the best choice?
A) Flat latex
B) Epoxy paint
C) Chalk paint
D) Acrylic craft paint
**Answer:** B) Epoxy paint
**Rationale:** Epoxy is chemically cured, providing a hard, abrasion-resistant surface that can
handle foot traffic and moisture. Standard latex or acrylic paints would wear quickly on a floor .
---
**Question 8**
What is the ideal temperature range for applying latex paint in NYC?
A) Below 32°F
