ARIZONA (AZ) CR34 PAINTING & WALL COVERING CONTRACTOR
LICENSE FINAL EXAM QUESTIONS WITH DETAILED- VERIFIED
ANSWERS- ALREADY GRADED A+ || NEWEST EXAM 2025-2026
Trade And Industrial Education/ Construction Management / Contractor
Licensing Preparation / Building Trades
This Arizona CR34 practice exam covers surface preparation (etching,
sanding, TSP cleaning, feathering, moisture testing), paint types and
finishes (latex, alkyd, epoxy, elastomeric, VOC limits, primers),
application techniques (brush, roller, airless spray, back rolling, wet
edge), wall covering installation (grass cloth, fiberglass, booking, sizing,
seam rolling), safety and compliance (lead‑safe RRP, respirators, ladder
safety, SDS, waste disposal), troubleshooting (peeling, blistering,
flashing, chalking, surfactant leaching), estimating and project
management (contracts, change orders, ROC requirements), and
Arizona contracting laws (A.R.S. §32‑1419, ROC jurisdiction, bond
requirements). Designed for PSI examination standards.
SECTION 1 – SURFACE PREPARATION (Questions 1–35)
1. What is the primary purpose of etching a concrete floor before
applying an epoxy coating?
A) To level the surface
B) To remove existing paint
C) To open the pores and create a mechanical bond
D) To dry out any moisture in the concrete
, Page 2 of 115
CORRECT ANSWER: C
Rationale: Etching (typically with an acid solution) microscopically
roughens the smooth concrete surface, creating a profile that allows the
coating to grip mechanically, vastly improving adhesion. Leveling, paint
removal, and drying are secondary or unrelated.
2. When dealing with extensive mold growth on an interior wall (over 10
square feet), what is the most appropriate first step for a painting
contractor?
A) Scrape off the mold and apply a stain-blocking primer
B) Clean the area with a bleach solution and let it dry
C) Recommend the homeowner hire a certified mold remediation
specialist
D) Sand the area thoroughly to remove all spores
CORRECT ANSWER: C
Rationale: Large-scale mold remediation is a specialized field and often
requires specific licenses. A painting contractor should not disturb large
areas of mold, as it can release harmful spores into the air. The
professional and safe approach is to refer the client to a specialist.
3. For a sound, previously painted wood surface that has a glossy sheen,
the most important preparation step is:
, Page 3 of 115
A) Applying a water-based primer
B) Degreasing with trisodium phosphate (TSP)
C) Sanding to dull the gloss and improve adhesion
D) Applying a coat of penetrating oil
CORRECT ANSWER: C
Rationale: Glossy surfaces are too smooth for paint to grip effectively.
Sanding dulls the gloss, creating a surface profile that new paint or
primer can bond to.
4. What is the first step in preparing a previously painted exterior wood
surface for repainting?
A) Apply primer immediately
B) Scrape loose and peeling paint
C) Wash with bleach
D) Sand the entire surface
CORRECT ANSWER: B
Rationale: Loose paint must be removed before any other preparation
steps to ensure proper adhesion of the new coating.

5. What is the recommended method for cleaning exterior surfaces
before painting in Arizona?
A) Dry brushing only
B) Pressure washing with mild detergent
C) Solvent wiping
D) Sandblasting
CORRECT ANSWER: B
Rationale: Pressure washing removes dust, dirt, and mildew. The Arizona
heat requires thorough cleaning to prevent coating failure.
6. What is the purpose of “feathering” when sanding a repair area?
A) To remove all paint
B) To create a smooth transition between the repair and surrounding
surface
C) To add texture
D) To speed up the process
CORRECT ANSWER: B
Rationale: Feathering blends the edges of a repair, preventing visible
ridges in the final finish.
