Coating Application and Inspection

This online engineering PDH course presents the technologies, techniques, advantages and limitations, equipment, typical coating types involved, and safety considerations for each type of application method.

The choice of an application method depends on the type of coating to be applied, the type and size of surface to be coated, and governing environmental regulations. There are various methods of coating application, including brush application, roller application, conventional spray, high volume-low pressure spray, airless spray, plural component spray, and electrostatic spray.

Approximately 85 percent of all premature coating failures are a result of poor surface preparation, inadequate mixing, thinning, and/or poor coating application. Onsite quality control inspection during surface preparation and coating application procedures can help prevent failures of these types. Proper inspection techniques must be combined with knowledgeable instrument use, good common sense, and thorough documentation of work activities and inspection checkpoints to help ensure specification compliance. The amount of inspection and the specific inspection checkpoints will vary with the type and size of the coating project. This course presents eleven quality control inspection procedures as follows:

• Pre-surface preparation inspection
• Ambient conditions
• Compressed air cleanliness
• Surface profile
• Surface cleanliness
• Paint storage, mixing, and thinning procedures
• Application techniques
• Wet and dry coating thickness
• Pinhole detection
• Adhesion
• Cure

This 3 PDH online course is applicable to engineers, design and construction personnel, and other technical professionals who are interested in gaining a better understanding of coating application and inspection.
