Description 2.1 This guide outlines the components of a complete vinyl painting system. A painting system shall consist of surface preparation by commercial blast cleaning or pick- ling, one coat of wash primer (when required), one coat of vinyl primer, one or two intermediate coat(s), and one finish coat of vinyl paint. 3. Reference Standards 3.1 The standards referenced in this guide are listed in Section 3.4 through 3.8 and form a part of the specification. 3.2 The latest issue, revision, or amendment of the reference standards in effect on the date of invitation to bid shall govern unless otherwise specified. 3.3 If there is a conflict between the requirements of any of the cited reference standards and the specification, the requirements of the specification shall prevail. 3.4 SSPC STANDARDS AND JOINT STANDARDS: PA 1Shop, Field, and Maintenance Painting of Steel PA 2Measurement of Dry Coating Thickness With Magnetic Gages PA Guide 4Guide to Maintenance Repaint- ing with Oil Base or Alkyd Paint- ing Systems Paint 8Aluminum Vinyl Paint Paint 9White (or Colored) Vinyl Paint Paint 27*Basic Zinc Chromate Vinyl Butyral Wash Primer PS 4.02Four-Coat Vinyl Painting System (For Fresh Water, Chemical, and Corrosive Atmospheres) PS 4.04Four-Coat White or Colored Vi- nyl Painting System (For Fresh Water, Chemical, and Corrosive Atmospheres) SP 2Hand Tool Cleaning SP 3Power Tool Cleaning SP 5/NACE No. 1White Metal Blast Cleaning SP 6/NACE No. 3Commercial Blast Cleaning SP 8Pickling SP 10/NACE No. 2Near-White Blast Cleaning 3.5 AMERICAN SOCIETY FOR TESTING AND MA- TERIALS (ASTM) STANDARD: D 3925Practice for Sampling Liquid Paints and Related Pigmented Coatings 3.6 FEDERAL SPECIFICATIONS AND STANDARDS: MIL-L-2838(canceled) Lacquer, Vinyl Resin, Gasoline and Water Resistant MIL-P-15930Primer, Vinyl-Zinc Chromate Type, (for Hot Spray) MIL-E-15935(canceled) Enamel, Outside, Gray, Vinyl-Alkyd MIL-E-15936(canceled) Enamel, Exterior, Gray, No. 27 Vinyl-Alkyd MIL-E-16188(canceled) Enamel, Exterior, Gray, No. 17 (Vinyl-Alkyd) MIL-E-16738(canceled) Enamel, Exterior, White, (Vinyl-Alkyd) 178 SSPC-PS Guide 4.00 November 1, 1982 Editorial Changes September 1, 2000 MIL-E-24292(canceled) Enamel, Exterior, Dark Gray (Vinyl-Alkyd) MIL-E-24306(canceled) Enamel, Exterior, Black (Vinyl-Alkyd) MIL-E-24307(canceled) Enamel, Exterior, Gray (Vinyl-Alkyd) MlL-P-28641(canceled) Primer Coating, Vinyl Chloride Copolymer, High-Build (for Steel and Masonry) MlL-P-28642(canceled) Paint (Topcoat), Vi- nyl Chloride Acetate Copolymer, High Build (for Steel and Ma- sonry) MIL-E-82401Enamel, Exterior, Vinyl-Alkyd, Red 3.7 US ARMY CORPS OF ENGINEERS STANDARDS: CW-09940Painting Hydraulic Structures and Appurtenant Works V-106Vinyl Type Red Oxide (Light or Dark Color) Paint V-766Vinyl-Type White (or Gray) Paint VZ-108Vinyl-Type Zinc-Rich Paint 3.8 U.S. BUREAU OF RECLAMATION STANDARDS: VR-3Vinyl Resin Paint VR-6Vinyl Resin Paint VR-M*Vinyl Resin Mastic 4. Surface Preparation 4.1 SSPC-SP 6, “Commercial Blast Cleaning,” or SSPC- SP 8, “Pickling. If specified in the procurement documents, better degrees of blast cleaning shall be substituted (SSPC- SP 5 or 10).

The high degree of cleanliness provided by these cleaning methods may be more economical or may be required for corrosive conditions. In maintenance re- painting when only small areas need to be cleaned, hand or power tool cleaning (SSPC-SP 2 or 3) may suffice.
