Society for Steel Painting Structures (SSPC) Surface Prep Standards:
Brush off blast cleaning (aka light blast cleaning, sweep blast):
Loosely-adhering material: 0%
Tightly-adhering material: 100%
Stains, streaks, shadows: 100%
Brush Off is specified to remove loose rust, mill scale and coatings, and uniformly roughen up a surface in preparation for a new coat. Tightly-adherent materials are permitted to remain.
Brush Off is specified where the expected life of the coating is short, such as ship hull antifouling, or in mild atmospheres and non-corrosive service environments, such as the exterior of a tank, in a rural location.
Commercial blast (aka thorough blast cleaning):
Loosely-adhering material:0%
Tightly-adhering material: 0%
Stains, streaks, shadows: 33%
Commercial Blast Cleaning specifies that all tightly-adhering matter must go. Shadows, streaks and stains can remain on up to 33% of the surface.
Commercial is specified when a high, but not perfect, degree of cleanliness is warranted. It’s common for repainting products that serve in non-corrosive environments and atmospheres, such as tanks and bridges.
White Metal Blast Cleaning (aka Blast Clean to Visibly Clean Steel)
Loosely-adhering material: 0%
Tightly-adhering material: 0%
Stains, streaks, shadows: 0%
White Metal is the highest grade of abrasive blast cleaning. No shadows, streaks or stains are permitted. When viewed without magnification, the surface shall be free of all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products and other foreign matter.
White metal is specified for steel serving under high temperatures, high pressures, and corrosive environments, and in cases where the catastrophic consequences of coating failure justify the extra expense, such as nuclear reactors, turbines, chemical tank linings, submarines, etc.
