Corrosion Protection for Industrial Coating Contractors
From Surface Assessment to Final Acceptance
Industrial coatings are the first line of defense against corrosion. The contractor's work determines how well that defense performs.
Corrosion protection involves more than applying paint to steel. Long-term performance depends on understanding the service environment, evaluating the condition of the structure, removing contaminants, achieving the required surface preparation, selecting the correct coating system, controlling application conditions, verifying film thickness, finding defects, and documenting the completed work.
Many structures also depend on cathodic protection to control corrosion at coating holidays, scratches, damaged areas, and exposed steel. Industrial coating contractors may not design these systems, but their work can directly affect how well the systems perform.
The AirSprayTech Academy program Corrosion Protection for Industrial Coating Contractors provides practical, contractor-focused instruction covering the entire corrosion-control process - from the first inspection of the structure through final coating acceptance and project closeout.
The coating is the primary corrosion barrier. Cathodic protection is the supporting system that helps protect exposed steel when that barrier is damaged.
Why This Training Matters
A coating can be properly mixed and sprayed yet still fail because the underlying corrosion risks were not recognized or controlled.
Residual salts can remain after blasting. The surface profile can be too shallow or too aggressive. Steel temperature can fall too close to the dew point. Edges and welds can receive insufficient film build. Recoat windows can be missed. Holidays can remain undetected. Cathodic-protection components can be damaged, disconnected, or accidentally coated.
Every one of these conditions can shorten coating life, increase repair costs, delay project acceptance, and expose the contractor to callbacks.
This program helps contractors understand the complete corrosion-protection system so they can recognize risks, improve workmanship, communicate concerns, and deliver coating work designed for long-term service.

Better Coating Work Begins with a Better Understanding of Corrosion
Industrial coating contractors do more than apply material. Their work protects critical assets, supports corrosion-control systems, and influences how long those assets remain in service.
Understanding the relationship between the steel, surface preparation, coating system, service environment, and supporting cathodic-protection system helps crews make better decisions and contractors deliver greater value.
Understand the corrosion. Prepare the surface. Apply the system correctly. Inspect the work. Protect the asset.
