Exam Preparation Guide
• This practice test covers all key domains of the Arizona CR-34 Painting & Wall
Covering contractor license exam, featuring 200 updated questions with highlighted
correct answers and detailed EXPERT RATIONALE to reinforce understanding.
• Study by attempting each question independently before checking the correct
answer and EXPERT RATIONALE — this active recall method maximizes retention
and prepares you for the real exam format.
1. What is the most critical step before applying paint to a new drywall
surface?
A. Applying two coats of paint immediately
B. Wetting the surface with water
C. Sanding with 220-grit sandpaper only
D. Applying a high-speed sprayer coat
E. Priming the surface with a drywall primer
Correct Answer: E. Priming the surface with a drywall primer
EXPERT RATIONALE: New drywall is highly porous and will absorb paint unevenly. A
drywall primer seals the surface, ensures uniform paint adhesion, and prevents
"flashing" — dull spots caused by uneven absorption.
,2. When preparing a previously painted surface that has peeling paint, what
should be done first?
A. Apply a bonding agent over the peeling areas
B. Sand the entire wall with 80-grit sandpaper
C. Remove all loose and peeling paint by scraping
D. Apply a skim coat of joint compound
E. Spray water on the surface to soften the paint
Correct Answer: C. Remove all loose and peeling paint by scraping
EXPERT RATIONALE: Peeling paint must be fully removed before any new coating is
applied. Painting over peeling paint will cause the new coat to fail as well. Scraping
ensures a stable base for subsequent preparation steps.
3. What type of sandpaper grit is most appropriate for final surface smoothing
before painting?
A. 36-grit
B. 60-grit
C. 80-grit
D. 100-grit
E. 150- to 220-grit
Correct Answer: E. 150- to 220-grit
EXPERT RATIONALE: Fine-grit sandpaper (150–220) is used for final smoothing
because it removes minor imperfections without leaving deep scratches that would show
through paint.
4. Which product is used to fill nail holes and small surface imperfections
before painting?
,A. Caulk
B. Patching plaster only
C. Wood filler exclusively
D. Spackling compound or lightweight joint compound
E. Epoxy adhesive
Correct Answer: D. Spackling compound or lightweight joint compound
EXPERT RATIONALE: Spackling compound and lightweight joint compound are the
standard products for filling small holes and imperfections on interior walls. They dry
quickly, sand easily, and accept paint well.
5. What is the purpose of using a tack cloth before painting wood surfaces?
A. To apply a thin primer coat
B. To roughen the wood for adhesion
C. To remove dust and fine particles after sanding
D. To seal the wood grain
E. To chemically bond the primer to the wood
Correct Answer: C. To remove dust and fine particles after sanding
EXPERT RATIONALE: A tack cloth is a sticky cloth designed to pick up fine dust and
particles left after sanding. If dust is not removed, it becomes trapped under the paint,
causing a rough, contaminated finish.
6. Before painting over a glossy surface, what preparation is required?
A. Apply two coats of primer
B. Clean with bleach solution only
C. Degloss by sanding or using a liquid deglosser
, D. Apply a bonding primer without any sanding
E. No preparation is needed for glossy surfaces
Correct Answer: C. Degloss by sanding or using a liquid deglosser
EXPERT RATIONALE: Glossy surfaces prevent good paint adhesion. Sanding or
applying a liquid deglosser creates a mechanical or chemical tooth on the surface,
allowing the new coat of paint to bond properly.
7. What is the recommended method for cleaning a surface contaminated
with grease before painting?
A. Sand the surface vigorously
B. Apply primer directly over grease
C. Wash with a TSP (trisodium phosphate) solution or degreaser
D. Use plain water and a cloth
E. Apply a bonding agent over the grease
Correct Answer: C. Wash with a TSP (trisodium phosphate) solution or
degreaser
EXPERT RATIONALE: Grease and oil repel paint and cause adhesion failure. TSP or a
commercial degreaser effectively cuts through grease, leaving a clean surface that will
accept paint properly.
8. When patching a large hole in drywall, what is the correct order of steps?
A. Prime, patch, sand, paint
B. Patch, allow to dry, sand, prime, paint
C. Sand, patch, prime, paint
D. Paint, patch, sand, prime
E. Patch, prime, paint, sand
