<br />H. Drywall - Exterior: 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
<br />smooth and all dust removed prior to painting. Exterior surfaces must be spackled with exterior
<br />grade compounds.
<br />I. Drywall - Interior: 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
<br />smooth and all dust removed prior to painting.
<br />J. Galvanized Metal: Clean per SSPC-SP1 using detergent and water or a degreasing cleaner to
<br />remove greases and oils. Apply a test area, priming as required. Allow the coating to dry at least
<br />one week before testing. If adhesion is poor, Brush Blast per SSPC-SP7 is necessary to remove
<br />these treatments.
<br />K. Plaster: Must be allowed to dry thoroughly for at least 30 days before painting, unless the
<br />products are designed to be used in high pH environments. Room must be ventilated while
<br />drying; in cold, damp weather, rooms must be heated. Damaged areas must be repaired with an
<br />appropriate patching material. Bare plaster must be cured and hard. Textured, soft, porous, or
<br />powdery plaster should be treated with a solution of 1 pint household vinegar to 1 gallon of water.
<br />Repeat until the surface is hard, rinse with clear water and allow to dry.
<br />L. Steel: Structural, Plate, And Similar Items: Should be cleaned by one or more of the surface
<br />preparations described below. These methods are used throughout the world for describing
<br />methods for cleaning structural steel. Visual standards are available through the Society of
<br />Protective Coatings. A brief description of these standards together with numbers by which they
<br />can be specified follow.
<br />1. Solvent Cleaning, SSPC-SP1: Solvent cleaning is a method for removing all visible oil,
<br />grease, soil, drawing and cutting compounds, and other soluble contaminants. Solvent
<br />cleaning does not remove rust or mill scale. Change rags and cleaning solution frequently
<br />so that deposits of oil and grease are not spread over additional areas in the cleaning
<br />process. Be sure to allow adequate ventilation.
<br />2. Hand Tool Cleaning, SSPC-SP2: Hand Tool Cleaning removes all loose mill scale, loose
<br />rust, and other detrimental foreign matter. It is not intended that adherent mill scale, rust,
<br />and paint be removed by this process. Before hand tool cleaning, remove visible oil,
<br />grease, soluble welding residues, and salts by the methods outlined in SSPC-SPI.
<br />3. Power Tool Cleaning, SSPC-SP3: Power Tool Cleaning removes all loose mill scale, loose
<br />rust, and other detrimental foreign matter. It is not intended that adherent mill scale, rust,
<br />and paint be removed by this process. Before power tool cleaning, remove visible oil,
<br />grease, soluble welding residues, and salts by the methods outlined in SSPC-SP1.
<br />4. White Metal Blast Cleaning, SSPC-SP5 or NACE 1: A White Metal Blast Cleaned surface,
<br />when viewed without magnification, shall be free of all visible oil, grease, dirt, dust, mill
<br />scale, rust, paint, oxides, corrosion products, and other foreign matter. Before blast
<br />cleaning, visible deposits of oil or grease shall be removed by any of the methods specified
<br />in SSPC-SP1 or other agreed upon methods.
