SSPC / NACE Standards

TMI Coatings is a certified SSPC-QP 1 and SSPC-QP 2 Certified contracting company. As a SSPC certified contractor, TMI Coatings follows SSPC and NACE Standards during all projects.

SSPC-SP 1, Solvent Cleaning:
Solvent cleaning is a method for removing all visible oil, grease, soil, drawing and cutting compounds, and other soluble contaminants from steel surfaces.
SSPC-SP 2, Hand Tool Cleaning:
Hand tool cleaning is a method of preparing steel surfaces by the use of non-power hand tools. Hand tool cleaning removes all loose mill scale, loose rust, loose paint, and other loose detrimental foreign matter. It is not intended that adherent mill scale, rust, and paint be removed by this process.
SSPC-SP 3, Power Tool Cleaning:
Power tool cleaning is a method of preparing steel surfaces by the use of power assisted hand tools. Power tool cleaning removes all loose mill scale, loose rust, loose paint, and other loose detrimental foreign matter. It is not intended that adherent mill scale, rust, and paint be removed by this process.
SSPC-SP 5/NACE No. 1, White Metal Blast Cleaning:
A white metal blast cleaned surface, when viewed without magnification, shall be free of all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter.
SSPC-SP 6/NACE No. 3, Commercial Blast Cleaning:
A commercial blast cleaned surface, when viewed without magnification, shall be free of all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter. Random staining shall be limited to no more than 33 percent of each unit area of surface.
SSPC-SP 7/NACE No. 4, Brush-Off Blast Cleaning:
A brush-off blast cleaned surface, when viewed without magnification, shall be free of all visible oil, grease, dirt, dust, loose mill scale, loose rust, and loose coating. Tightly adherent mill scale, rust, and coating may remain on the surface.
SSPC-SP 10/NACE No. 2, Near-White Blast Cleaning:
A near-white metal blast cleaned surface, when viewed without magnification, shall be free of all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter. Random staining shall be limited to no more than 5 percent of each unit area of surface.
SSPC-SP 11, Power Tool Cleaning to Bare Metal:
This standard is suitable where a roughened, clean, bare metal surface is required, but where abrasive blasting is not feasible or permissible.
SSPC-SP 12/NACE No. 5, Surface Preparation and Cleaning of Metals by Waterjetting Prior to Recoating:
This standard is written primarily for applications in which the substrate is carbon steel. However, waterjetting can be used on nonferrous substrates such as bronze, aluminum, and other metals such as stainless steel. This standard does not address the cleaning of concrete.
SSPC-SP 13/NACE No. 6, Surface Preparation of Concrete:
An acceptable prepared concrete surface should be free of contaminants, laitance, loosely adhering concrete, and dust, and should provide a sound, uniform substrate suitable for the application of protective coating or lining systems.
