What you do
Industrial shotblasters and surface treatment painters prepare and protect steel and concrete structures against corrosion using abrasive blasting and specialist coating systems. Surface preparation involves grit or shot blasting using centrifugal blasting machines or pressure pot blast systems to achieve specified surface cleanliness and anchor profile grades (typically Sa 2.5 or Sa 3 to ISO 8501-1). Following blasting, coating application — by airless spray, conventional spray, roller, or brush — applies primer, build coats, and topcoats of epoxy, polyurethane, zinc silicate, or other specialist systems to the specification in the protective coating schedule.
Inspection and quality control involves monitoring ambient conditions (temperature, relative humidity, dew point), measuring dry film thickness using a digital gauge, conducting adhesion testing (cross-cut or pull-off), and holiday (porosity) testing using a wet sponge or high-voltage spark tester on immersed or underground coatings. Knowledge of international standards — ISO 8501, ISO 8503, SSPC, NACE — is required for complex specification work.
The Corrodere Institute (University of Northampton) and FROSIO (Norwegian body for coating inspection) provide the recognised qualifications: Corrodere Certificate in Protective Coatings and FROSIO Inspector Level I–III. The steel fabrication, oil and gas, offshore wind, water treatment, and bridge maintenance markets are the principal employers.
Why this career is resilient
Steel is the world's most widely used structural material and it rusts — corrosion protection of steel structures is a perpetual maintenance requirement driven by safety, longevity, and regulatory compliance. Offshore oil platforms, wind monopiles, bridges, storage tanks, and industrial pipework all require periodic recoating on inspection-driven cycles that cannot be deferred indefinitely. The technical knowledge required to achieve a compliant surface preparation and coating application — understanding ambient conditions, blast cleanliness, film thickness, and application defects — is skill-intensive and inspectable against international standards. Qualified inspectors (FROSIO, NACE) command significant premiums for overseeing and signing off complex specification work.
A typical day
Morning: arrive at a steel fabrication shop — check the ambient conditions using a Wheatstone hygrometer, record temperature and relative humidity, calculate the dew point, and confirm conditions are within the specification window. Set up the airless spray unit and begin applying zinc silicate primer to a batch of structural steelwork, maintaining the specified wet film thickness using a wet film gauge. Afternoon: carry out dry film thickness measurements on yesterday's primer coat, photograph all non-conforming areas, and prepare a correction schedule. Begin applying the intermediate epoxy coat where the primer readings are confirmed within specification. End of day: complete the daily quality control inspection records and submit to the coatings inspector.
