What does SSPC-SP 6 describe?

SSPC-SP 6 describes industrial blast cleaning, which is a specific standard that outlines the requirements for the surface preparation of steel by abrasive blast cleaning to remove contaminants and achieve a desired surface profile. This level of cleanliness is aimed at ensuring optimal adhesion of coatings.

In this context, the standard focuses on high-quality surface preparation which is critical in industrial environments where durability and performance are vital. The process typically involves using various types of abrasives to remove rust, mill scale, and old paint from steel surfaces, resulting in a clean, uniform surface suitable for the application of protective coatings.

The other options refer to different methods or levels of surface preparation: commercial blast cleaning, power tool cleaning, and brush-off blast cleaning each have their own specific applications and cleanliness standards that do not align with the rigorous requirements outlined in SSPC-SP 6.
