SECTION 1: Inspection, Assessment & Job Setup

When assessing a large commercial spray project, what is the most critical factor to establish first?

A. Paint colour selection

B. Availability of labour

C. Surface condition, access, and environmental control

D. Brand of spray pump

2 / 20

On an active construction site, what presents the greatest risk to a sprayed finish?

A. Lighting conditions

B. Movement of other trades and airborne dust

C. Paint colour mismatch

D. Pump pressure settings

3 / 20

When preparing to spray an elevator interior, what is the most important setup consideration?

A. Increasing pump pressure

B. Using larger spray tips

C. Controlling airflow, containment, and overspray

D. Reducing masking time

4 / 20

4. Why is it important to understand the full job sequence before starting large-area spraying?

A. To reduce paint cost

B. To ensure efficient workflow and avoid rework or access issues

C. To improve drying time

D. To select spray tips

5 / 20

5. What is the main consequence of poor site setup before spraying begins?

A. Faster application

B. Improved finish

C. Increased risk of contamination and rework

D. Reduced equipment wear

6 / 20

SECTION 2: Surface Preparation (Large Areas & Mixed Substrates)

6. When spraying over previously painted commercial walls, what is the most appropriate preparation approach?

A. Spray directly if visually clean

B. Light abrasion, cleaning, and spot priming where required

C. Remove all existing coatings

D. Apply heavy primer without sanding

7 / 20

What is the best method to ensure a consistent finish across large wall areas?

A. Vary spray technique across sections

B. Use different tip sizes

C. Maintain consistent preparation and application technique

D. Increase pump pressure

8 / 20

When working with mixed substrates (e.g. plasterboard, metal, MDF), what is the correct approach?

A. Use the same preparation for all

B. Adjust preparation and priming based on each substrate

C. Focus only on the largest surface

D. Increase paint thickness

9 / 20

9. Why is dust control more critical in spray applications than roller applications?

A. It improves drying

B. Spray application amplifies surface contamination in the finish

C. It reduces paint usage

D. It improves masking

10 / 20

What is the primary risk of inconsistent preparation across large surfaces?

A. Reduced drying time

B. Increased adhesion

C. Visible variation in finish and texture

D. Reduced material use

11 / 20

SECTION 3: Spray Pump Systems & Application

11. What is the main advantage of airless spray pumps when applying water-based coatings to large areas?

A. Increased drying time

B. High transfer efficiency and speed of application

C. Reduced control

D. Lower coverage

12 / 20

12. What is the effect of using a spray tip that is too large for the material?

A. Reduced output

B. Finer finish

C. Excessive material application and potential runs

D. Slower spraying

13 / 20

13. What is the most appropriate way to determine spray pressure when using an airless system?

A. Always use maximum pressure

B. Set pressure based on manufacturer guidance and adjust to achieve proper atomisation

C. Match pressure to room size

D. Use the same pressure for every job

14 / 20

14. When spraying large flat areas, what is the most effective technique to maintain a uniform finish?

A. Random spray direction

B. Circular motion

C. Consistent passes with controlled overlap and steady speed

D. Heavy first coat

15 / 20

15. Why is maintaining a “wet edge” important when spraying large surfaces?

A. Reduces material cost

B. Speeds up drying

C. Prevents lap marks and visible joins

D. Improves adhesion only

16 / 20

SECTION 4: Finishing, Quality Control & Site Practice

16. What is the most common defect when spraying large areas without consistent technique?

A. Improved gloss

B. Even finish

C. Banding or striping across the surface

D. Faster curing

17 / 20

17. What should be checked immediately after completing a sprayed section?

A. Equipment storage

B. Paint cost

C. Coverage consistency, defects, and uniformity

D. Masking tape quality

18 / 20

18. What is the main risk of removing masking too late on large projects?

A. Tearing edges or damaging the coating

B. Improved finish

C. Faster job

D. Increased adhesion

19 / 20

19. When working in occupied or near-complete buildings, what becomes critical?

A. Speed only

B. Minimal masking

D. Protection of surrounding areas and controlled overspray

C. Lower pressure

20 / 20

20. What defines a high-quality completion of a commercial spray project?
