PRODUCT APPLICATION .
SURFACE PREPARATION
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 (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 is 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. WARNING! If you scrape, sand or remove old
paint from any surface, you may release lead paint dust. LEAD IS
TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS
ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN
CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID
EXPOSURE. Wear a NIOSH-approved respirator to control lead
exposure. Carefully clean up with a wet mop or HEPA vacuum. For
additional information, contact the U.S. EPA/Lead Information
Hotline at 1-800-424-LEAD or log on to
www.epa.gov/lead.
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.
