This examination is designed specifically for candidates preparing for the Arizona Registrar of
Contractors (ROC) CR34 – Painting & Wall Covering Contractor License Exam. The questions
comprehensively cover all major content areas tested on the official state licensing examination, including:
1. Surface Preparation (etching, mold remediation, lead safety, sanding, moisture control)
2. Paint Types & Properties (latex, oil, epoxy, primers, sheens, VOCs, specialty coatings)
3. Wall Coverings (wallpaper types, adhesives, hanging techniques, removal, defect prevention)
4. Application Techniques (spraying, rolling, brushing, wet edge maintenance, film thickness)
5. Problem Diagnosis & Repair (blistering, peeling, chalking, alligatoring, fisheyes, efflorescence)
6. Tools & Equipment (spray tips, brushes, rollers, pressure washers, safety devices)
7. Safety & Regulations (EPA RRP lead rule, OSHA fall protection, respirators, fire safety)
8. Estimating & Bidding (square foot calculations, labor rates, overhead, change orders)
9. Arizona Business & Law (ROC licensing, contracts, prompt payment, lien waivers, statute of limitations)
Format: Each question includes four answer choices (A, B, C, D). The correct answer is clearly marked
in bold italics. Each question is followed by a bolded "Explanation" label and an italicized
explanation that provides the reasoning, code reference, or industry standard supporting the correct
answer.
Section 1: Surface Preparation (Questions 1–25)
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
Explanation Etching roughens smooth concrete, creating a profile for mechanical adhesion.
,2. When dealing with extensive mold growth on an interior wall (over 10 sq ft), 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
c) Recommend the homeowner hire a certified mold remediation specialist
d) Sand the area thoroughly
Explanation Large mold areas require specialized remediation; disturbing them releases
harmful spores.
3. For a sound, previously painted wood surface with a glossy sheen, the MOST
important preparation step is:
a) Applying a water-based primer
b) Degreasing with TSP
c) Sanding to dull the gloss and improve adhesion
d) Applying a coat of penetrating oil
Explanation Sanding creates "tooth" for new paint to adhere properly.
4. What is the minimum recommended moisture content for wood siding before
painting?
a) It doesn't matter
b) Below 12%
c) 15–20%
d) Above 20%
Explanation High moisture content causes blistering, peeling, and rot.
,5. What is the minimum temperature for applying most paints?
a) 35°F
b) 50°F
c) 60°F
d) 70°F
Explanation Below 50°F, adhesion and drying are compromised.
6. Which of the following is the best method to test for lead-based paint on a pre-1978
surface?
a) Visual inspection
b) Smell test
c) EPA-recognized lead test kit
d) Scraping and burning a sample
Explanation Lead test kits provide immediate, compliant results for RRP rule compliance.
7. When power washing exterior siding before painting, what is the maximum
recommended pressure to avoid damaging wood?
a) 500 PSI
b) 1,000–1,500 PSI
c) 2,500 PSI
d) 3,500 PSI
Explanation Higher pressures can gouge wood fibers and force water behind siding.
8. What is "chalking" in relation to exterior paint?
a) A primer application method
b) A clear protective coating
c) Degradation of the paint binder into a powdery residue
d) A texture additive
, Explanation Chalking occurs when UV exposure breaks down the resin, leaving pigment
powder.
9. How should chalked surfaces be prepared before repainting?
a) Apply paint directly over the chalk
b) Use a heat gun
c) Pressure wash or scrub, then apply a bonding primer
d) Sand with 40-grit paper
Explanation Chalk must be removed and a primer used to ensure adhesion.
10. What is the purpose of applying a shellac-based primer over a water stain?
a) To increase gloss
b) To add texture
c) To block tannin and water-soluble stains from bleeding through
d) To speed drying
Explanation Shellac seals stains that water-based and oil-based primers cannot block.
11. When preparing galvanized metal for painting, which product must be used first?
a) Latex primer
b) Epoxy primer
c) Etching or galvanized metal primer
d) Polyurethane topcoat
Explanation Galvanized surfaces are non-porous and require special etch primers for
adhesion.
