- Application Data
Surface Preparation:
All surfaces must be clean, dry, and free of contaminants. All dirt, grease, rust, mill scale, or loose chalky paint must be removed in conformance with the provisions in section 59-2,”Painting Structural Steel’, or Section 59-3, “Painting Galvanized Surfaces’ of the State of California Department of Transportation Standard Specifications unless otherwise specified in the contract special provisions.The retrieval and analysis ofsoluble salts on substrates shall
be conducted in accordance with “SSPC: The Society for Protective Coatings,” rule. The substrate mustbe cleaned so that the maximum level of soluble salts does not exceed 10 micrograms per square centimeter. Areas should be tested at the rate of 3 tests for the first 1000 square feet prepared per day, and one test for each additional 1000 square feet or portion thereof, at randomly selected locations.
When less than 1000 square feet of surface area is prepared in a shift, at least 2 tests should be performed. lf levels of soluble salts exceed the maximum, the entire area represented by the test should be cleaned again and tested until soluble salt levels conform to this requirement.
Unpainted new structural steel: Blast clean near white with appropriate abrasive media. Allsurfaces mustbe clean, dry, and free of contaminants. Apply appropriate primer to the recommended ary film thickness. ° SSPC-SP1S * SSPC-SP10
Previously painted structural steel: Steam clean or power wash to remove all dirt, grease, contaminants, and gloss from existing paint. Spot clean rusty areas to remove all rust and mill scale.- SSPC-SP1 * SSPC-SP6
- SSPC-SP2 ¢ SSPC-SP11
- SSPC-SP3
Galvanized steel: Steam clean or power wash to remove all dirt, grease, and contaminants. Spot clean to remove rust and mill scale. Roughen surface by whip blasting or light sanding. Do not remove intact galvanizing.

Safety & Health
- Health and Safety
Warning:
FLAMMABLE LIQUID AND VAPOR. May be harmful if swallowed or inhaled. Vapor may affect the brain or nervous system causing dizziness, headache, or nausea and can cause nose and throat irritation. Keep away from sparks, heat, or open flames. Use with adequate ventilation. Avoid breathing of vapor. Avoid contactwith eyes, skin, andclothing. Wash hands thoroughly after using and before eating and smoking. Wear an appropriate, properly fitted respirator (NIOSH/MSHA approved) during and after application unless air monitoring demonstrates vapor levels are below applicable limits. Follow respirator manufacturer’s directions for use. Keep container closed when not in use. If spillage occurs, absorband dispose ofaccordintgo local regulations.
Notice:
Intentional misuse by deliberately concentrating and inhaling the contents may be harmfulor fatal. Reports have associated repeated and prolonged occupational overexposure to solvents with permanentbrain and nervous system damage.
First Aid:
Should eye contact occur, flush with plenty of water for at least 15 minutes and get medical attention if vision is disturbed. For skin, wash thoroughly with soap and water. If swallowed, seek medical attention immediately. DO NOT induce vomiting.
