The selection of an appropriate application method relies on several factors, including the nature of the coating, the size and type of the surface to be coated, and relevant environmental regulations. Multiple methods are available for coating application, such as brush application, roller application, conventional spray, high volume low-pressure spray, airless spray, plural component spray, and electrostatic spray. This course offers comprehensive insights into the technologies, techniques, advantages, limitations, equipment, typical coating types, and safety considerations associated with each application method.

Course Objectives:

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
