What does SSPC-SP 14 represent in cleaning standards?

SSPC-SP 14 refers specifically to "Industrial Blast Cleaning," which is a surface preparation standard developed by the Society for Protective Coatings (SSPC). This standard outlines the requirements for preparing surfaces by using abrasive blasting techniques to remove contaminants and prepare the substrate for the application of coatings.

Industrial Blast Cleaning is more aggressive than other cleaning processes, leading to a surface that has a higher degree of cleanliness and is suitable for environments where harsher conditions are expected. The goal is to achieve a surface that is adequately prepared for coatings to adhere properly, considering the unique challenges faced in industrial settings.

In contrast, standards such as "Near-white blast cleaning" and "Commercial blast cleaning" have different levels of cleanliness and surface profiles, while "Power tool cleaning" involves hand or power tools rather than mechanical blasting, making them distinctly different from the requirements and conditions outlined in SSPC-SP 14.
