DESCRIPTION AND USES
Rust-Oleum Stops Rust Primer Sprays provide a sound base for application of Stops Rust® enamels on heavily rusted metal. Use of primers promotes topcoat adhesion and helps prevent chipping, cracking and peeling and eliminates the need for multiple coats of enamel finish. It features a comfort tip with a wider finger pad to reduce fatigue caused by continuous spraying and the any-angle tip which allows
you to spray at any angle. Not for use on galvanized steel.
7769 Rusty Metal Primer is designed for heavily rusted surfaces only. 7780 Clean Metal Primer is designed for lightly rusted, bare metal, or previously painted surfaces.
PRODUCT APPLICATION
PAINTING CONDITIONS
Use outdoors or in a well ventilated area such as an open garage. Use when temperature is between 50-90°F (10-32°C) and humidity is below 65% to ensure proper drying. Do not apply to surfaces, when heated, exceed 200°F (93°C). Do not apply to galvanized steel. Avoid spraying in very windy and dusty conditions. Cover surrounding area to protect from spray mist.
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.
APPLICATION
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. Keep the can 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
Dry and recoat times are based on 70°F (21°C) and 50% relative humidity. Allow more time at cooler temperatures. Dries to touch in 15-30 minutes and dries to handle in 1-2 hours. Apply a topcoat or recoat within 1 hour or after 48 hours.
