PRODUCT APPLICATION
SURFACE PREPARATION
Remove all dirt, grease, oil, salt, and chemical contaminants by washing the surface with a commercial detergent, or other suitable cleaning method. Rinse with fresh water and allow to thoroughly dry. Remove loose paint and rust with a wire brush or sandpaper. 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. Removal of old paint by sanding, scraping or other means may generate dust or fumes that contain lead.
APPLICATION
Use outdoors or in a well-ventilated area such as an open garage. Use when temperature is between 50ºF (10ºC) and 90ºF (32ºC) and humidity is below 85% to ensure proper drying. Priming is not recommended. Do not use on metal directly exposed to open flame or in direct contact with food, such as a grill grate. Avoid application in very windy and dusty conditions. Cover surrounding area to protect from spray mist.
Shake can vigorously for one minute after the mixing ball begins to rattle. If mixing ball fails to rattle DO NOT STRIKE CAN. Contact Rust-Oleum. Shake often during use. Hold can upright 10-16” from surface and spray in a steady back-and-forth motion, slightly overlapping each stroke. Keep the can the same distance from the surface and keep in motion while spraying. Apply two or more light coats a few minutes apart to avoid drips and runs. Do not use near open flame.
DRY & RECOAT TIMES
Dry and recoat times are based on 70ºF and 50% relative humidity. Allow more time at cooler temperatures. Dries to touch in 30 minutes and to handle in 1-2 hours. Allow paint to dry for 1 hour before heating. Upon first heating, product may emit smoke and harmless odor. May recoat at any time. Heat curing is required for temperature use over 500ºF. To improve performance and durability, heat cure at 450ºF for one hour.
CLEAN-UP
