NYCHA Supervisor Painter Written Exam QUESTIONS
AND VERIFIED ANSWERS WITH RATIONALES JUST
RELEASED
NYCHA Supervisor Painter Written Exam preparation guide, structured as you requested. It begins with
a targeted, point-form summary of the exam coverage, followed by 250 scenario-based multiple-choice
questions. Each question includes a correct answer and an italicized rationale based on NYCHA
specifications, NYC Local Laws, OSHA standards, and EPA RRP rules.
Summarized Exam Coverage (Point Form)
• NYCHA Regulations & Standards: NYCHA follows HUD-approved color schemes and material
standards for uniformity and cost control . Buildings constructed before 1978 are presumed to
contain lead-based paint .
• Paint Technology & Sheens: Semi-gloss latex provides best durability and scrub resistance for
high-traffic NYCHA hallways . Flat paint hides wall imperfections but shows marks easily . High-
gloss is easiest to clean and most durable for doors and trim . Gloss level progression: flat (0-5%)
→ eggshell (10-25%) → satin (25-35%) → semi-gloss (35-70%) → high-gloss (70-85%) .
• Paint Types & Binders: Latex paint uses acrylic or vinyl resin binders (water-based) . 100%
acrylic provides superior adhesion, flexibility, and weather resistance compared to vinyl
acrylic . Epoxy paint is required for basement floors due to abrasion and moisture
resistance . High-heat enamel (200°F+) required for radiators .
• Primers: Shellac-based primer is best for covering water stains, smoke damage, and severe
bleeding . Bonding primer required over glossy existing paint without sanding . PVA (Polyvinyl
Acetate) primer is required over bare drywall . Encapsulant primer for previously lead-painted
surfaces .
• NYC Local Laws: Local Law 47 limits VOCs: 100 g/L for flat paint, 150 g/L for non-flat . Local Law
1 (2024 update) requires lead-safe work practices in pre-1978 buildings .
• Surface Preparation: Proper order: Clean → Scrape → Sand → Prime . Efflorescence (white
powder on masonry) requires removal, alkali-resistant primer, then masonry paint . "Mud
cracking" indicates paint applied too thickly . "Surfactant leaching" (brownish drips) caused by
high humidity or cool temperatures during application . "Alligatoring" from applying
incompatible paint layers .
• Mold Protocol: Must clean and treat mold source before painting; moisture source must be
corrected .
• Tools & Application: Angled sash brush is best for cutting in around trim and corners . Roller
nap: 1/4"-3/8" for smooth drywall ceilings ; 3/8" for NYCHA plaster ; longer naps for textured
walls . Natural bristle brushes for oil-based/alkyd paints; synthetic for latex . Paint
sprayer advantage: speed and uniform coverage for large areas . 4-foot roller extension for 12-
foot ceilings .
• Paint Defects & Causes: Peeling most often caused by moisture or applying over glossy surface
without proper prep . Blistering caused by moisture trapped under film or painting in direct
sunlight on hot days . Chalking due to UV degradation or use of low-quality paint . Fish
eyes from oil or silicone contamination . Flash rusting on metal after cleaning . Checking fine
cracks from aging or temperature changes .
• Temperature Requirements: Minimum application temperature for latex paint: 50°F (10°C) .
Ideal range: 50-85°F . Below 50°F, paint fails to coalesce properly .
, Page 2 of 147
• VOCs & Environmental Compliance: Local Law 47 limits VOCs to improve indoor air quality . Oil-
based paint classified as hazardous waste disposal .
• Lead Safety (EPA RRP & NYC Local Law 1): P100 respirators required for lead paint work (N95
insufficient) . HEPA vacuums required for lead dust cleanup . Prohibited: Wire brushing, dry
sanding without HEPA, using heat guns above 1100°F, open flame burning . Work area
containment required for lead disturbance . Proper cleanup sequence: HEPA vacuum → wet
wipe → HEPA vacuum again .
• OSHA Safety & Ladder Safety: Fiberglass ladders required near electrical work (aluminum
conducts electricity) . Extension ladder angle: 75 degrees (4-to-1 rule) . Scaffold
inspection required before each use . Guardrails required on scaffolds . Lock-out/Tag-out for
confined space safety .
• Supervisory Duties: Primary responsibility: Ensure work quality, safety, and
productivity . Corrective training first before discipline . Document safety violations and follow
agency procedures . Toolbox talks weekly (10-15 min, documented) . Situational
leadership adapts to skill level . Private coaching for quality issues preserves dignity .
• Estimating & Math: Wall area = height × length (subtract doors/windows) . Coverage: one gallon
covers ~350 sq ft (2 coats) . Add 10% waste factor for spillage, overspray, equipment cleaning .
Crew productivity measured as output per labor hour .
• Order of Operations: Ceilings → walls → trim → doors (ceilings first, drips on unpainted
walls) . Cutting in with brush before rolling .
• PPE & Chemical Safety: Safety Data Sheets (SDS) provide hazard and PPE information . Solvent
overexposure symptoms: dizziness, headache — requires evacuation and medical
evaluation . Dust masks insufficient for chemical vapors .
250 Scenario-Based MCQs with Rationales
Section 1: Paint Technology & Materials Selection (1-30)
1. As a NYCHA supervisor, you are selecting paint for a high-traffic hallway. Which paint type provides
the best resistance to repeated scrubbing?
A. Flat latex
B. Eggshell acrylic
C. Semi-gloss latex
D. Chalk paint
, Page 3 of 147
Answer: C
Rationale: Semi-gloss latex forms a hard, durable film that withstands frequent washing and scuffing,
essential for high-traffic public housing corridors. Flat paint lacks washability, and chalk paint is not
durable for this use .
2. You need to specify paint for 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
Rationale: Epoxy paint is highly durable, resistant to chemicals and abrasion, and stands up well to foot
traffic and potential moisture in basements. Standard latex or acrylic paints would wear quickly on a
floor .

3. A crew member asks you what the primary binder is in latex paint. How should you respond?
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 characteristic of oil-based paints, while epoxy is a separate chemical family .
4. A resident reports a brown water stain on the living room ceiling. Which primer must you specify to
prevent bleed-through?
A. Latex primer
B. Shellac-based primer
C. Oil-based primer
D. Bonding primer
