PRODUCT APPLICATION .
SURFACE PREPARATION
ALL SURFACES: Remove all dirt, grease, oil, salt and
chemical contaminants by washing the surface with Krud
Kutter
®
Cleaner Degreaser, 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 (SSPC-SP-2) or power tool (SSPC-SP-3)
clean to remove all loose rust, mill scale, and deteriorated
previous coatings. If abrasive blasting cleaning is used, then
two coats of recommended primer are required. See the primer
Technical Data Sheet for more information.
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
7400 System Enamels are compatible with most coatings, but
a test patch is suggested.
APPLICATION
Apply only when air and surface temperatures are between
32-100°F (0-38°C) and surface temperature is at least 5°F
(3°C) above the dew point.
