Copper — S-W 7: Remove all oil, grease, dirt, oxide and other foreign material by cleaning per SSPC-SP2, Hand Tool
<br />Cleaning.
<br />Drywall—Interior and Exterior — S-W 8: Must be clean and dry. All nail heads must be set and spackled. Joints must be
<br />taped and covered with a joint compound. Spackled nail heads and tape joints must be sanded smooth and all dust removed
<br />prior to painting. Exterior surfaces must be spackled with exterior grade compounds.
<br />Galvanized Metal— S-W 10: Allow to weather a minimum of 6 months prior to coating. Clean per SSPC-SPI using detergent
<br />and water or a degreasing cleaner, then prime as required. When weathering is not possible or the surface has been treated with
<br />chromates or silicates, first Solvent Clean per SSPC-SP I and apply a test area, priming as required. Allow the coating to dry at
<br />least one week before testing. If adhesion is poor, Brush Blast per SSPC-SPI6 is necessary to remove these treatments.
<br />Plaster — S-W 11: Must be allowed to dry thoroughly for at least 30 days before painting. Room must be ventilated while
<br />drying; in cold, damp weather, rooms must be heated. Damaged areas must be repaired with an appropriate patching material.
<br />Bare plaster must be cured and hard. Textured, soft, porous, or powdery plaster should be treated with a solution of 1 pint
<br />household vinegar to I gallon of water. Repeat until the surface is hard, rinse with clear water and allow to dry.
<br />Steel/Ferrous Metal Substrates
<br />SSPC-SP1- Solvent Cleaning: Solvent cleaning is a method for removing all visible oil, grease, soil, drawing and cutting
<br />compounds, and other soluble contaminants. Solvent cleaning does not remove rust or mill scale. Change rags and cleaning
<br />solution frequently so that deposits of oil and grease are not spread over additional areas in the cleaning process. Be sure to
<br />allow adequate ventilation. Follow manufacturer's safety recommendations when using solvents. For complete instructions,
<br />refer to Steel Structures Paint Council Surface Preparation Specification No.!. (Refer to each products cleaning instructions.
<br />Many acrylic coatings will state; When cleaning the surface per SSPC-SP1, use only an emulsifying industrial detergent,
<br />followed by a water rinse. Do not use hydrocarbon solvents for cleaning.)
<br />SSPC-SP2 - Hand Tool Cleaning: Hand Tool Cleaning removes all loose mill scale, loose rust, and other detrimental foreign
<br />matter. It is not intended that adherent mill scale, rust, and paint be removed by this process. Mil scale, rust, and paint are
<br />considered adherent if they cannot be removed by lifting with a dull putty knife. Before hand tool cleaning, remove visible oil,
<br />grease, soluble welding residues, and salts by the methods outlined in SSPC-SP I . For complete instructions, refer to Steel
<br />Structures Paint Council Surface Preparation Specification No.2.
<br />SSPC-SP3 - Power Tool Cleaning: Power Tool Cleaning removes all loose mill scale, loose rust, and other detrimental foreign
<br />matter. It is not intended that adherent mill scale, rust, and paint be removed by this process. Mil scale, rust, and paint are
<br />considered adherent if they cannot be removed by lifting with a dull putty knife. Before power tool cleaning, remove visible oil,
<br />grease, soluble welding residues, and salts by the methods outlined in SSPC-SP I. For complete instructions, refer to Steel
<br />Structures Paint Council Surface Preparation Specification No.3.
<br />SSPC-SP5 / NACE 1 - White Metal Blast Cleaning: A White Metal Blast Cleaned surface, when viewed without
<br />magnification, shall be free of all visible oil, grease, dirt, dust, mill scale, rust, paint, oxides, corrosion products, and other
<br />foreign matter. Before blast cleaning, visible deposits of oil or grease shall be removed by any of the methods specified in
<br />SSPC-SP I or other agreed upon methods. For complete instructions, refer to Joint Surface Preparation Standard SSPC-SP5/
<br />NACE No.1 .
<br />SSPC-SP6 / NACE 3 - Commercial Blast Cleaning: A Commercial Blast Cleaned surface, when viewed without
<br />magnification, shall be free of all visible oil, grease, dirt, dust, mill scale, rust, paint, oxides, corrosion products, and other
<br />foreign matter, except for staining. Staining shall be limited to no more than 33 percent of each square inch of surface area and
<br />may consist of light shadows, slight streaks, or minor discoloration caused by stains of rust, stains of mill scale, or stains of
<br />previously applied paint. Before blast cleaning, visible deposits of oil or grease shall be removed by any of the methods
<br />specified in SSPC-SP 1 or other agreed upon methods. For complete instructions, refer to Joint Surface Preparation Standard
<br />SSPC-SP6/NACE No.3.
<br />SSPC-SP7 / NACE 4- Brush-Off Blast Cleaning: A Brush-Off Blast Cleaned surface, when viewed without magnification,
<br />shall be free of all visible oil, grease, dirt, dust, loose mill scale, loose rust, and loose paint. Tightly adherent mill scale, rust,
<br />and paint may remain on the surface. Mil scale, rust, and coating are considered adherent if they cannot be removed by lifting
<br />with a dull putty knife. Before blast cleaning, visible deposits of oil or grease shall be removed by any of the methods specified
<br />in SSPC-SP I or other agreed upon methods. For complete instructions, refer to Joint Surface Preparation Standard
<br />SSPC-SP7/NACE No.4.
