standard covers the requirements for near-white blast cleaning of
unpainted or painted steel surfaces by the use of abrasives. These
requirements include the end condition of the surface and materials
and procedures necessary to achieve and verify the end condition.
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,
except for staining as noted.
Random staining
shall be limited to no more than 5 percent of each unit area of
surface as defined, and may consist of light shadows, slight
streaks, or minor discolorations caused by stains of rust, stains of
mill scale, or stains of previously applied coating.
SSPC-SP 11,
Power Tool Cleaning to Bare Metal
This standard
covers the requirements for power tool cleaning to produce a bare
metal surface and to retain or produce a minimum 25 micrometer (1.0
mil) surface profile.
This standard
is suitable where a roughened, clean, bare metal surface is
required, but where abrasive blasting is not feasible or
permissible.
This standard
differs from SSPC-SP 3,
Power Tool Cleaning, in that SSPC-SP 3 requires only the removal of
loosely adherent materials, and does not require producing or
retaining a surface profile.
This standard
differs from SSPC-SP 15,
Commercial Grade Power Tool Cleaning, in that SSPC-SP 15 allows
stains of rust, paint, or mill scale to remain on the surface. SSPC-SP
11 only allows materials to remain at the bottom of pits.
SSPC-SP 12/NACE
No. 5, Surface Preparation and Cleaning of Metals by Waterjetting
Prior to Recoating
This standard
describes the use of waterjetting to achieve a defined degree of
cleaning of surfaces prior to the application of a protective
coating or lining system. These requirements include the end
condition of the surface plus materials and procedures necessary to
verify the end condition. This standard is limited in scope to the
use of water only.
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. Cleaning of concrete is discussed in
SSPC SP-13/NACE No. 6.
SSPC-SP 13/NACE
No. 6, Surface Preparation of Concrete
This standard
gives requirements for surface preparation of concrete by
mechanical, chemical, or thermal methods prior to the application of
bonded protective coating or lining systems.

requirements of this standard are applicable to all types of
cementitious surfaces including cast-in-place concrete floors and
walls, precast slabs, masonry walls, and shotcrete surfaces.
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.
When required,
a minimum concrete surface strength, maximum surface moisture
content, and surface profile range should be specified in the
procurement documents (project specifications).

requirements include the end condition of the surface and materials
and procedures necessary to achieve and verify the end condition.
An industrial
blast cleaned surface, when viewed without magnification, shall be
free of all visible oil, grease, dust, and dirt. Traces of tightly
adherent mill scale, rust, and coating residues are permitted to
remain on 10% of each unit area of the surface if they are evenly
distributed.
The traces of
mill scale, rust, and coating shall be considered tightly adherent
if they cannot be lifted with a dull putty knife. Shadows, streaks,
and discolorations caused by stains of rust, stains of mill scale,
and stains of previously applied coating may be present on the
remainder of the surface.
SSPC-SP 15,
Commercial Grade Power Tool Cleaning
