1. A coatings inspector arrives at a steel fabrication site before surface preparation
begins. Which activity should be performed first to establish the inspection
requirements for the project?
A. Measure the dry film thickness of the existing coating
B. Review the project specification and applicable inspection requirements
C. Begin abrasive blasting to verify the abrasive profile
D. Select the coating color specified by the owner
Answer: B
The specification establishes the required surface preparation, coating system, environmental
limits, inspection criteria, and acceptance requirements. The inspector should understand
these requirements before inspection activities begin.
2. What is the primary purpose of applying a protective coating to carbon steel?
A. Increase the electrical conductivity of the steel
B. Reduce the weight of the steel structure
C. Separate the steel surface from the corrosive environment
D. Increase the hardness of the substrate
Answer: C
A protective coating primarily acts as a barrier between the steel and its environment,
reducing the conditions necessary for corrosion.
3. During a pre-job conference, the contractor proposes a coating system different
from the one specified in the contract. What should the inspector do?
A. Approve it if the contractor has used it successfully elsewhere
B. Reject it immediately without documentation
C. Allow the applicator to choose the system
D. Refer the proposed change to the responsible authority for approval
Answer: D
,An inspector should not independently authorize specification changes. Proposed
substitutions should be reviewed and approved by the party responsible for technical or
contractual authorization.
4. Which condition is most directly responsible for electrochemical corrosion of
exposed carbon steel?
A. Presence of an electrolyte connecting anodic and cathodic areas
B. Excessive coating thickness
C. High surface profile
D. Low coating viscosity
Answer: A
Electrochemical corrosion requires anodic and cathodic areas, an electrical path, and an
electrolyte. Moisture commonly provides the electrolyte in atmospheric service.
5. A freshly blasted steel surface is left uncoated overnight in a humid environment.
What is the principal concern?
A. Increased coating flexibility
B. Formation of flash rust or renewed corrosion
C. Reduced abrasive consumption
D. Excessive coating gloss
Answer: B
Clean steel can rapidly develop flash rust or corrosion when exposed to moisture, particularly
under humid conditions.
6. Which document normally provides the manufacturer's recommended mixing ratio,
thinner limitations, application methods, and curing requirements?
A. Daily inspection report
B. Safety meeting record
C. Product data sheet
D. Purchase order
Answer: C
The product data sheet provides technical information required for proper preparation and
application of the coating material.
7. An inspector observes that the steel surface is visibly contaminated with oil before
abrasive blasting. What is the most appropriate action?
, A. Proceed with blasting because the abrasive will remove the oil
B. Apply primer over the contaminated surface
C. Increase blast pressure
D. Require appropriate cleaning before abrasive blasting
Answer: D
Oil and grease should be removed before abrasive blasting because blasting can spread or
embed contaminants rather than reliably eliminating them.
8. Which inspection activity verifies that ambient conditions are suitable for coating
application?
A. Measuring temperature, relative humidity, and dew point
B. Measuring coating color
C. Measuring abrasive hardness only
D. Measuring steel tensile strength
Answer: A
Environmental measurements help determine whether conditions are suitable for coating
application and whether condensation may form on the steel.
9. What is the primary reason an inspector compares steel temperature with dew point
temperature?
A. To determine coating color
B. To assess the risk of condensation on the steel
C. To determine abrasive size
D. To calculate coating volume solids
Answer: B
If the steel approaches the dew point, moisture can condense on the surface and interfere
with coating adhesion and performance.
10. A coating manufacturer specifies that application should not occur when steel
temperature is less than 3°C above the dew point. The inspector measures steel
temperature at 24°C and dew point at 22°C. What should the inspector conclude?
A. Conditions automatically meet the requirement
B. The coating can be applied if the surface looks dry
C. The specified temperature separation has not been achieved
D. Relative humidity is irrelevant
Answer: C
, The difference is only 2°C, which is below the specified 3°C separation. The application should
not proceed under that requirement.
11. Which surface preparation method uses compressed air to propel abrasive particles
against a steel surface?
A. Solvent cleaning
B. Hand-tool cleaning
C. Power-tool cleaning
D. Abrasive blast cleaning
Answer: D
Abrasive blast cleaning propels abrasive media against the substrate to remove
contaminants, corrosion products, and existing coatings as required.
12. What is the primary purpose of a surface profile?
A. Provide mechanical tooth that can contribute to coating adhesion
B. Increase steel thickness
C. Reduce coating coverage
D. Prevent all chemical corrosion by itself
Answer: A
A properly prepared surface profile provides microscopic peaks and valleys that can improve
mechanical adhesion and coating performance.
13. An inspector finds that the blast-cleaned surface has a profile significantly deeper
than the coating manufacturer's recommended range. What is the primary
concern?
A. The steel will become electrically insulated
B. The coating may not adequately cover the profile valleys
C. The coating will automatically cure faster
D. The surface will become impossible to inspect
Answer: B
An excessively deep profile can make it difficult for the coating to cover the valleys
adequately, potentially contributing to premature corrosion or inadequate film thickness.
14. Which instrument is commonly used to measure the surface profile of blast-cleaned
steel?
