methods used to minimise corrosion.
2. Surface Preparation
o Learn cleaning methods, abrasive blasting, power tools, hand tools, SSPC/NACE surface
cleanliness standards, and surface profile requirements.
3. Coating Types and Components
o Identify common coating systems including epoxies, polyurethanes, zinc-rich primers,
acrylics, and alkyd coatings.
4. Environmental Conditions
o Measure and interpret air temperature, surface temperature, dew point, relative
humidity, and their influence on coating application.

o Proper use of dry film thickness gauges, wet film gauges, psychrometers, dew point
meters, profile comparators, and holiday detectors.
6. Coating Application Methods
o Brush, roller, conventional spray, airless spray, plural-component equipment, and
application best practices.
7. Film Thickness Inspection
o Measure wet film thickness (WFT) and dry film thickness (DFT), understand tolerances,
and verify specification compliance.
8. Coating Defects
o Identify common defects such as blistering, pinholes, holidays, runs, sags, mud cracking,
orange peel, and adhesion failures.
9. Documentation and Inspection Reports
o Maintain accurate inspection records, daily reports, environmental logs, calibration
records, and non-conformance documentation.
10. Inspector Safety
Follow PPE requirements, confined space awareness, hazard communication, ventilation
practices, and safe inspection procedures.
,Question 1
Which primary purpose of protective industrial coatings best explains why steel
structures receive coatings before entering corrosive service environments?
A. Improve electrical conductivity
B. Increase metal hardness
C. Create a barrier separating steel from corrosive environments
D. Reduce structural weight
Answer: C
Rationale: Protective coatings primarily act as barriers that isolate steel from
moisture, oxygen, and contaminants responsible for corrosion.
Question 2
Which electrochemical component within a corrosion cell undergoes metal loss
because oxidation reactions occur at that location?
A. Cathode
B. Electrolyte
C. Anode
D. Metallic coating
Answer: C
Rationale: Oxidation occurs at the anode, causing metal atoms to leave the
surface and produce corrosion.
Question 3
,Why should coating inspectors carefully verify surface cleanliness before coating
application begins on prepared steel substrates?
A. Surface cleanliness determines paint colour.
B. Cleanliness improves coating appearance only.
C. Contaminants significantly reduce coating adhesion and long-term
performance.
D. Clean surfaces eliminate curing requirements.
Answer: C
Rationale: Oil, grease, dust, salts, and other contaminants interfere with adhesion
and reduce coating service life.
Question 4
Which environmental measurement is especially important because coating
application should normally not occur when condensation is likely?
A. Wind direction
B. Atmospheric pressure
C. Dew point
D. Altitude
Answer: C
Rationale: Coating should generally not be applied when the steel temperature is
too close to the dew point because condensation may form.
Question 5
, Why is abrasive blasting commonly preferred over hand tool cleaning for critical
industrial coating applications?
A. It always produces polished steel.
B. It removes mill scale and creates an anchor profile.
C. It eliminates coating curing time.
D. It permanently prevents corrosion.
Answer: B
Rationale: Abrasive blasting removes contaminants and creates a surface profile
that improves coating adhesion.
Question 6
Which instrument is primarily used to measure dry film thickness after a coating
has completely cured?
A. Wet sponge
B. Dry film thickness gauge
C. Surface thermometer
D. Psychrometer
Answer: B
Rationale: DFT gauges verify whether applied coatings meet specified thickness
requirements.
