NYC NYCHA SUPERVISOR PAINTER PRACTICE
EXAM QUESTIONS AND ANSWERS
Question 1: Which type of paint is MOST appropriate for painting metal railings in a NYCHA building?
A. Latex paint
B. Oil-based enamel
C. Water-based acrylic
D. Milk paint
CORRECT ANSWER: B. Oil-based enamel
Rationale: Oil-based enamel provides superior adhesion, durability, and rust inhibition for metal surfaces like
railings, especially in high-traffic public housing environments. Latex/acrylic paints are better for
drywall/wood; milk paint is decorative and not durable for metal.
Question 2: What is the FIRST step in preparing a previously painted wall for repainting?
A. Apply primer
B. Clean the surface
C. Sand the surface
D. Apply paint
CORRECT ANSWER: B. Clean the surface
Rationale: Surface preparation begins with cleaning to remove dirt, grease, and loose material. Sanding
follows to smooth imperfections; priming addresses stains/porosity; painting is the final step. Proper prep
ensures paint adhesion and longevity.
Question 3: Which safety equipment is REQUIRED when painting in a confined space per OSHA standards?
A. Safety glasses only
B. Respirator, ventilation, and attendant
C. Hard hat and gloves
D. Ear protection only
CORRECT ANSWER: B. Respirator, ventilation, and attendant
Rationale: Confined spaces require atmospheric monitoring, ventilation, respirators if needed, and an
attendant outside the space per OSHA 1910.146. Safety glasses/gloves are general PPE but insufficient alone
for confined space entry.

,Question 4: Which paint sheen is MOST appropriate for NYCHA apartment walls?
A. Flat/matte
B. Eggshell
C. Semi-gloss
D. High-gloss
CORRECT ANSWER: B. Eggshell
Rationale: Eggshell sheen offers a balance of durability, washability, and low reflectivity, ideal for residential
walls. Flat paint is less washable; semi-gloss/high-gloss are better for trim/doors due to higher sheen and
durability.
Question 5: What is the PRIMARY purpose of a primer?
A. To provide color
B. To seal porous surfaces and improve adhesion
C. To add texture
D. To reduce drying time
CORRECT ANSWER: B. To seal porous surfaces and improve adhesion
Rationale: Primer seals porous surfaces (drywall, wood), blocks stains, and creates a uniform surface for
topcoat adhesion. It does not provide final color (topcoat does), add texture, or significantly reduce drying
time.
Question 6: Which tool is BEST for cutting in edges and corners when painting?
A. Roller
B. Paint sprayer
C. Angled sash brush
D. Paint pad
CORRECT ANSWER: C. Angled sash brush
Rationale: Angled sash brushes (2-3 inches) provide precision for cutting in edges, corners, and trim. Rollers
cover large areas; sprayers are for large surfaces but require masking; paint pads are for flat surfaces but less
precise for edges.
Question 7: What is the MINIMUM drying time between coats of latex paint under normal conditions?
A. 30 minutes
B. 1-2 hours
C. 4-6 hours
Page 2 of 59
,D. 24 hours
CORRECT ANSWER: B. 1-2 hours
Rationale: Latex paints typically require 1-2 hours drying time between coats at 77°F (25°C) and 50% humidity.
Oil-based paints require 6-8 hours. Always follow manufacturer instructions; humidity/temperature affect
drying.
Question 8: Which surface preparation is REQUIRED before painting over mildew?
A. Sand only
B. Clean with bleach solution, rinse, and dry
C. Apply primer directly
D. Paint over with mildew-resistant paint
CORRECT ANSWER: B. Clean with bleach solution, rinse, and dry
Rationale: Mildew must be killed and removed before painting. Clean with 1:3 bleach:water solution, rinse
thoroughly, and allow to dry. Painting over mildew traps moisture and allows regrowth.
Question 9: Which type of paint is MOST appropriate for NYCHA bathroom ceilings?
A. Flat latex
B. Mildew-resistant semi-gloss
C. Oil-based enamel
D. Textured paint
CORRECT ANSWER: B. Mildew-resistant semi-gloss
Rationale: Bathrooms have high humidity; mildew-resistant semi-gloss paint provides moisture resistance,
durability, and easy cleaning. Flat latex absorbs moisture; oil-based enamel is less common for ceilings;
textured paint is decorative but harder to clean.
Question 10: What is the PRIMARY purpose of a drop cloth?
A. To mix paint
B. To protect floors and furnishings from paint spills
C. To clean brushes
D. To measure paint coverage
CORRECT ANSWER: B. To protect floors and furnishings from paint spills
Rationale: Drop cloths (canvas or plastic) protect surfaces from paint spills, drips, and splatters. They are
essential for efficient cleanup and preventing damage to NYCHA property.

, Question 11: Which safety protocol is REQUIRED when working on scaffolding?
A. Wear a hard hat only
B. Use fall protection when over 6 feet
C. Work alone for efficiency
D. Use ladders instead of scaffolding
CORRECT ANSWER: B. Use fall protection when over 6 feet
Rationale: OSHA requires fall protection (harness, guardrails) when working at heights over 6 feet. Hard hats
are general PPE; working alone is unsafe; ladders are not substitutes for scaffolding on large projects.
Question 12: Which paint application method is MOST efficient for large, flat wall surfaces?
A. Brush
B. Roller
C. Sprayer
D. Paint pad
CORRECT ANSWER: B. Roller
Rationale: Rollers cover large, flat surfaces quickly and evenly with minimal overspray. Brushes are for
edges/trim; sprayers are efficient but require extensive masking and ventilation; paint pads are for smaller flat
areas.
Question 13: What is the CORRECT procedure for disposing of leftover oil-based paint?
A. Pour down the drain
B. Throw in regular trash
C. Take to a hazardous waste facility
D. Evaporate and dispose of can in trash
CORRECT ANSWER: C. Take to a hazardous waste facility
Rationale: Oil-based paint is hazardous waste and must be disposed of at designated facilities per NYC DEP
regulations. Latex paint can be dried and disposed of in trash; oil-based requires special handling.
Question 14: Which surface defect is caused by painting over a dirty or greasy surface?
A. Blistering
B. Peeling
C. Fish eyes
D. Wrinkling
