The Arizona CR34 Painting & Wall Covering Contractor exam – completely different from Version 1! Prepare with confidence using this second comprehensive practice test covering every topic on the AZ Registrar of Contractors (ROC) licensing exam. Includes: Surface preparation (lead-safe, pressure washing, sanding) Paint types (latex, alkyd, epoxy, elastomeric, polyurethane) Application techniques (brushing, rolling, spraying, back-rolling) Color theory (mixing, matching, LRV, lighting effects) Safety (VOCs, respirators, ladders, lead-safe RRP) Arizona regulations (bond, CE, contracts, liens, ROC complaints) Section 1: Surface Preparation
1. 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 Loose paint must be removed before any other preparation steps to ensure proper adhesion of the new coating.
2. 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 Pressure washing removes dust, dirt, and mildew; the Arizona heat requires thorough cleaning to prevent coating failure. 3. 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 Feathering blends the edges of a repair, preventing visible ridges in the final finish. 4. Which solvent is commonly used to remove wax or silicone from a surface before painting? a) Water b) Mineral spirits or denatured alcohol c) Acetone d) Lacquer thinner Wax and silicone contaminants prevent paint adhesion; mineral spirits effectively removes these without damaging most substrates. 5. What is "back priming"? a) Painting the front surface twice b) Applying primer to the back side of wood siding or trim before installation c) Painting the interior walls d) Applying primer after topcoat Back priming prevents moisture from penetrating the back of wood, reducing warping and peeling.
11. When should you stop sanding lead-based paint? a) When it is smooth b) Do not sand lead-based paint; use wet scraping or chemical strippers c) After 10 minutes d) When the surface is dry Sanding lead-based paint creates toxic dust; Arizona regulations require specific lead-safe work practices. 12. What is the proper way to clean a surface after sanding? a) Dry cloth only b) Tack cloth or vacuum with HEPA filter c) Compressed air d) Feather duster Tack cloth picks up fine dust; HEPA vacuums capture hazardous particles, especially important for lead or silica dust. 13. What is "mil" in surface preparation terminology? a) A type of paint b) A unit of measurement equal to 0.001 inch, used for coating thickness c) A sanding tool d) A cleaning solution Coating thickness is measured in mils; proper preparation ensures uniform application thickness. 14. What is the recommended approach for preparing galvanized metal for painting? a) Sand only b) Wash with solvent, then apply a self-etching primer c) Paint directly d) Heat the surface Galvanized metal has a smooth, oily surface; etching primer provides mechanical and chemical adhesion. 15. What is "sweating" of a surface? a) Drying too fast b) Moisture condensation on a surface c) Paint bubbling d) Sanding residue In Arizona's desert climate, temperature differentials can cause condensation; surfaces must be dry before painting.
16. What is the minimum temperature for applying most water-based paints? a) 32°F (0°C) b) 50°F (10°C) c) 70°F (21°C) d) 90°F (32°C) Most latex paints require temperatures above 50°F for proper film formation and curing. 17. What is the maximum recommended surface temperature for painting in Arizona? a) 80°F (27°C) b) 95°F (35°C) c) 110°F (43°C) d) 120°F (49°C) Extreme heat causes paint to dry too quickly, leading to poor adhesion, brush marks, and blistering. 18. What is "flash rust" on metal surfaces? a) Rust that appears immediately after cleaning b) Rapid oxidation that occurs within hours of surface preparation c) Rust under paint d) Rust on aluminum Flash rust must be removed before painting; Arizona's low humidity can actually help prevent it compared to humid climates. 19. What is the proper way to prepare concrete floors for epoxy coating? a) Wash only b) Acid etch or diamond grind c) Sand only d) Apply directly Concrete must be profiled (roughened) to allow epoxy to mechanically bond; acid etching or grinding is required. 20. What is "efflorescence" on masonry surfaces? a) A type of paint b) White, powdery salt deposits on concrete or brick c) A primer type d) A drying agent Efflorescence must be removed before painting; it indicates moisture movement through the masonry.
Section 2: Paint & Coating Types (Questions 26-50)
26. What is the primary binder in latex paint? a) Oil b) Acrylic or vinyl acrylic polymer c) Epoxy d) Alkyd The binder holds pigment particles together and adheres them to the surface; acrylic resins provide durability and flexibility. 27. What is the primary vehicle (carrier) in latex paint? a) Mineral spirits b) Water c) Turpentine d) Alcohol Water evaporates after application, leaving the binder and pigment as a dry film. 28. What type of paint is most durable for exterior trim in Arizona's sun? a) Flat latex b) High-quality acrylic latex or 100% acrylic c) Chalk paint d) Milk paint 100% acrylic paints resist fading, chalking, and cracking better than vinyl acrylic blends, especially in intense sunlight. 29. What is "chalking" in exterior paint? a) A primer type b) The release of pigment powder from the paint film due to UV degradation c) A texture effect d) A drying defect Chalking is a natural degradation process but excessive chalking indicates paint failure. 30.

What is the primary advantage of oil-based polyurethane over water-based? a) Faster drying b) Warmer, amber tone and higher durability c) Lower odor d) Easier cleanup Oil-based polyurethane adds an amber color that enhances wood grain but yellows over time; water-based stays clear. 44. What type of paint is recommended for garage floors? a) Flat latex b) Two-part epoxy or polyaspartic coating c) Wall paint d) Chalk paint Epoxy and polyaspartic coatings resist chemicals, hot tire pickup, and heavy foot/vehicle traffic. 45.
