How to Apply 7400 System Zinc Chormate Primers Yellow

Surface Primer


All Surfaces : Remove all dirt, grease, oil, salt and chemical contaminants by washing the surface with Pure Strength Cleaner/Degreaser, item 3599402, commercial detergent or other suitable cleaner. Rinse thoroughly with fresh water and allow to fully dry. All surfaces must be dry at time of application.


Steel : Hand tool clean (SSPC-SP-2) or power tool clean (SSPC-SP-3) to remove all loose rust, mill scale, and deteriorated previous coatings. Abrasive blasting to a minimum Commercial Grade (SSPC-SP-6, NACE 3) with a 1-2 mils (25-50µ) surface profile is recommended for optimal performance. Abrasive blast cleaned steel requires two coats of primer. 769 Primer is intended for sound rusted steel only. Do not use 769 Primer on clean or abrasive clean steel.


Previously Coated : Previously coated surfaces must be sound and in good condition. Smooth, hard, or glossy finishes should be scarified by sanding to create a surface profile. The Rust-Oleum Industrial Enamel Primers are compatible with most coatings, but a test patch is suggested.


Application


Apply only when the air and surface temperatures are between 32-100°F (0-38°C) and the surface temperature is at least 5°F (3°C) above the dew point. Abrasive blast clean steel requires two coats of primer.
