What does SSPC-SP3 signify?

SSPC-SP3 signifies "Power tool cleaning." This is a standard of the Society for Protective Coatings (SSPC) that outlines the procedures for using power tools to remove rust, mill scale, and other contaminants from metal surfaces prior to coating. Power tool cleaning is advantageous because it can be more efficient and effective than hand tool cleaning, particularly on larger surfaces or in more severe conditions.

Understanding the significance of different SSPC standards is essential for anyone involved in surface preparation for coatings, as these procedures directly impact the performance and longevity of the coating system applied. Proper surface preparation is critical for achieving the desired adhesion and durability of protective coatings.
