Before one selects a finishing system for any exposure, the amount and type of surface preparation that will be done under actual operating conditions must be determined. After these limitations have been established, select the finishing system best suited for the exposure and within the limitations that were established by adaptable surface preparation procedures. Poor surface preparation cannot be overcome by using expensive coatings.  \nThis section contains information on:  \nI. Abrasive blast cleaning  \nII. Hand tool cleaning  \nIII. Power tool cleaning  \nIV. Solvent cleaning  \nV. Surface preparation of miscellaneous metals  \nVI. Surface preparation of concrete  \nVII. Preparing existing paint for recoating  \nVIII. Use of a barrier coat for topcoating conventional paints with heavy duty, strong solvent coatings.  \nI. Abrasive Blast Cleaning (Sandblasting) Precede the blast cleaning with suitable solvent or detergent cleansing to remove chemicals, grease, oil or other contaminants.  \nDefined Grades of Blast Cleaning  \n1. NACE \\#1 SSPC-5-63 White Metal Blast White metal blast cleaned surface finish. Defined as a surface with a gray - white (uniform metallic) color, slightly roughened to form suitable anchor pattern for coatings. The surface is free of all oil, grease, dirt, rust, paint, mill scale, oxides, corrosion products and all other foreign matter. (Compares to SSPC-SP5-63 White Metal Blast)  \n2. NACE \\#2 SSPC-SP 10-63T Near White Blast Cleaning. Near white blast cleaned surface finish. Defined as a surface from which all oil, grease, dirt, mill scale, rust, oxides, paint, corrosion products, or other foreign matter have been removed except for any light shadows, streaks or slight discoloration (of oxide bonded with metal) . At least 95% of any given surface area has the appearance of NACE \\#1, and the remainder of that area is limited to slight discoloration. (Compares to SSPCSP10-63T, Near White Blast)  \n3. NACE \\#3 SSPC-SP 6-63 Commercial Blast Cleaning. Commercial blast cleaned surface. Defined as a surface from which all oil, grease, dirt, rust scale and foreign matter have been completely removed and all rust, mill scale, and old paint have been removed except for slight shadows, streaks or discoloration’s caused by rust stains or mill scale oxide binder. At least two-third (2/3) of the surface area shall be free of all visible residues and the remainder shall be limited to light discoloration, slight staining or light residues mentioned above. If the surface is pitted, slight residues of rust or paint are found in the bottom of pits.(Compares to SSPC-SP 6-63, Commercial Blast )  \n4. NACE \\#4 SSPC-SP 7-63 Brush-off Blast Cleaning. Brush-off blast cleaned surface finish. Defined as a surface from which all oil, grease, dirt, loose rust scale, loose mill scale and loose paint have been are removed, but if tightly adhering are permitted to remain if they have been exposed to the abrasive blast pattern, so that numerous flecks of the underlying metal are uniformly distributed over the entire surface.(Compares to SSPC-SP7-63 Brush-Off Blast)  \nAdditional Suggestions for Abrasive Blast Cleaning Procedure:  \n(a) Strive for highest rate of production attainable with air volume and pressure available.  \n(b) Evaluate combination blast and vacuum system to reduce abrasive fall out. Waterblast or sand injected water blast will reduce fall out.  \n(c) Precede blast cleaning with appropriate solvent or detergent removal of all oil, grease or chemical contaminants.  \n(d) Remove any weld flux and splatter with suitable power tools preceding abrasive blast.  \n(e) Use clean","cbCaiqftlAjLJe8i","https://ap.wps.com/l/cbCaiqftlAjLJe8i","pdf",54523,"English","# Surface Preparation\n## Scope and selection principles\n## Surface preparation methods\n## I.
