|  | | Below is the list of Surface Preparation Standards we provide for our services as outlined by the SSPC.
Surface Preparation Standards:
5.1 SSPC-SP1, “Solvent Cleaning” – Removal of all detrimental foreign matter such as oil, grease, dirt, soil, salts, drawing and cutting compounds, and other contaminants from steel surfaces by use of solvents, emulsions, cleaning compounds, steam or other similar materials and methods which involve a solvent or cleaning action
5.5 SSPC-SP5/NACE No.1, “White Metal Blast Cleaning” – Removal of all mill scale, rust, rust scale, paint or foreign matter by the use of abrasives propelled through nozzles or by centrifugal wheels. A White Metal Blast Cleaned Surface Finish is defined as a surface with a gray-white, uniform metallic color, slightly roughened to form a suitable anchor pattern for coatings. The surface, when viewed without magnification, shall be free of all oil, grease, dirt, visible mill scale, rust, corrosion products, oxides, paint, or any other foreign matter.
5.6 SSPC-SP6/NACE No.3, “Commercial Blast Cleaning” – Removal of mill scale, rust, rust scale, paint or foreign matter by the use of abrasives propelled through nozzles or by centrifugal wheels, to the degree specified. A Commercial Blast Cleaned Finish is defined as one from which all oil, grease, dirt, rust scale and foreign matter have been completely removed from the surface and all rust, mill scale and old paint have been completely removed except for slight shadows, streaks, or discoloration caused by rust stain, mill scale oxides or slight, tight residues of paint or coating that may remain; if the surface is pitted, slight residues of rust or paint may be found in the bottom of pits; at least two-thirds of each square inch of surface area shall be free of all visible residues and the remainder shall be limited to the light discoloration, slight staining or tight residues mentioned above.
5.7 SSPC-SP7/NACE No.4, “Brush Off Blast Cleaning” – Removal of loose mill scale, loose rust, and loose paint, to the degree hereafter specified, by the impact of abrasives propelled through nozzles or by centrifugal wheels. It is not intended that the surface shall be free of all mill scale, rust, and paint. The remaining mill scale, rust, and paint should be tight and the surface should be sufficiently abraded to provide good adhesion and bonding of paint. A Brush-Off Blast Cleaned Surface Finish is defined as one from which all oil, grease, dirt, rust scale, loose mill scale, loose rust and loose paint or coatings are removed completely but tight mill scale and tightly adhered rust, paint and coatings are permitted to remain provided that all mill scale and rust have been exposed to the abrasive blast pattern sufficiently to expose numerous flecks of the underlying metal fairly uniformly distributed over the entire surface.
5.10 SSPC-SP10/NACE No.2, “Near-White Blast Cleaning” – Removal of nearly all mill scale, rust, rust scale, paint, or foreign matter by the use of abrasives propelled through nozzles or by centrifugal wheels, to the degree hereafter specified. A Near-White Blast Cleaned Surface Finish is defined as one from which all oil, grease, dirt, mill scale, rust, corrosion products, oxides, paint or other foreign matter have been completely removed from the surface except for very light shadows, very slight streaks or slight discoloration's caused by rust stain, mill scale oxide, or light, tight, residues of paint or coating that may remain. At least 95 percent of each square inch of surface area shall be free of all visible residues, and the remainder shall be limited to the light discoloration mentioned above.
5.11 SSPC-SP11, “Power tool Cleaning to Bare Metal” – Metallic surfaces which are prepared according to this specification, when viewed without magnification, shall be free of all visible oil, grease, dirt, dust mill scale, rust, paint, oxide, corrosion products and other foreign matter. Slight residues of rust and paint may be left in the lower portion of pits if the original surface is pitted. When painting is specified, the surface shall be roughened to a degree suitable for the specified paint system. The surface profile shall not be less than 1 mil (25 microns)
5.13 SSPC-SP13/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 dry, sound, uniform substrate suitable for the application of protective coating or lining systems. Depending upon the desired finish and system, a block filler may be required.
5.14 SSPC-SP14/NACE No.8, “Industrial Blast Cleaning” – Uses abrasives propelled through nozzles or by centrifugal wheels to remove mill scale, rust, paint, and other foreign matter. Traces of tightly adherent rust, mill scale, or previously applied paint may remain on 10% of each 3-in x 3-in surface areas. Cleaned surface must be roughened to impart a profile suitable for the coating system.
5.15 Dry Ice Cleaning Process – This process utilizes custom dry ice blasting equipment in conjunction with specially formulated high-density dry ice pellets to perform the cleaning. This equipment is able to achieve various levels of cleaning that are project specific. A test section will be cleaned upon arrival to the job site. The customer or customers representative must be on site at the beginning of the project to review and sign off that the level of cleaning we are able to achieve meets or exceeds the parameters of the project.
5.16 Fire Restoration Process – This process utilizes either Baking Soda, Corn Cob or Dry Ice Cleaning to remove the soot and char residue from the fire. We utilize the "White Rag Test" to verify that we have achieved the desired level of cleaning. If the rag can be rubbed across the cleaned surface and no discoloration is on the rag, the surface is deemed clean. There are some times when the fire is hot enough that it permanently discolors the wood or underlying surface. In these cases we are able to remove all of the soot and char, but the surface may still appear darker than the surrounding areas.
5.17 Graffiti Removal – There are several different applications that can be used for the removal of graffiti. When dealing with concrete, brick, stone and other similar surfaces either baking soda removal or chemical removal is the methods to be utilized. When removing graffiti from painted metal surfaces or glass the chemical removal option is the recommended method.
5.18 Pressure Washing – In this application pressure washing equipment will be utilized to achieve the desired surface finish. This equipment is able to achieve various levels of cleaning that are project specific. A test section will be cleaned upon arrival to the job site. The customer or customers representative must be on site at the beginning of the project to review and sign off that the level of cleaning we are able to achieve meets or exceeds the parameters of the project.
5.19 Baking Soda Cleaning – This process utilizes custom baking soda blasting equipment in conjunction with specially formulated baking soda crystals to perform the cleaning. This equipment is able to achieve various levels of cleaning that are project specific. A test section will be cleaned upon arrival to the job site. The customer or customers representative must be on site at the beginning of the project to review and sign off that the level of cleaning we are able to achieve meets or exceeds the parameters of the project.
5.20 Torbo Blast Cleaning – This process utilizes the Torbo Blast wet abrasive blasting system. The Torbo Blaster is able to utilize any type of blast media that is heavier than water. This equipment is able to achieve various levels of cleaning that are project specific. A test section will be cleaned upon arrival to the job site. The customer or customers representative must be on site at the time to review and sign off that the level of cleaning we are able to achieve meets or exceeds the parameters of the project.
