What type of cleaning is described by SSPC-SP 14?

The correct answer describes Industrial Blast Cleaning, which is specified in SSPC-SP 14. This standard outlines a method where abrasive materials are propelled at high velocity against the surface to remove contaminants such as rust, old paint, and other surface pollutants. This cleaning technique is particularly effective for achieving a clean, rough surface profile, which is essential for ensuring proper adhesion of subsequent coatings.

Industrial Blast Cleaning is designed for steel surfaces that are heavily corroded or contaminated and requires specialized equipment that can deliver a consistent and thorough cleaning action. Through this method, not only is the surface prepared adequately for painting, but it also enhances the overall durability and performance of the coating system to be applied afterward. Understanding this standard is crucial for inspectors to ensure compliance with surface preparation requirements for protective coatings.
