This standard is based upon the technical requirements for coating repair developed by the National Marine Ship Standardization Technical Committee Ship Repair Branch Technical Committee in China, but may be applicable for use globally provided it meets the field requirements of marine maintenance and fulfills the environmental protection requirements of the appropriate governing body.
This course presents at a high-level the surface preparation process for steel with an overview of hand and power-tool cleaning, dry abrasive blasting and waterjetting as well as the associated standards referenced when these methods are used to prepare steel for the application of protective coatings.
At the end of this course students will be able to:
1. Explain the purpose, importance, and steps of the surface preparation process.
2. Summarize how contaminants, environmental conditions, surface defects and abrasive media affect surface preparation.
3. Identify the initial condition of the steel and level of cleanliness using written standards and visual guides.
4. Describe the advantages and disadvantages along with the tools, and equipment associated with hand and power tool cleaning, dry abrasive blasting and waterjetting.
