READ ENTIRE LABEL BEFORE APPLYING
DESCRIPTION AND USES
Rust-Oleum® Stops Rust® Primers provide a sound base for application of Stops Rust® enamels on heavily rusted steel. Primers provide twice the rust prevention than using enamels alone. The use of primers promotes topcoat adhesion and helps prevent chipping, cracking and peeling. Use of Stops Rust primers eliminates the need for multiple coats of enamel finish. Not for use of galvanized
steel.
PAINTING CONDITIONS
Apply only when air and surface temperatures are between 50-90 °F (10-32 °C) and humidity is below 85% to ensure proper drying. Do not apply to surfaces that will exceed 200 °F (93 °C). Do not use on galvanized steel.
SURFACE PREPARATION
ALL SURFACES: Remove all dirt, grease, oil, salt and chemical contaminants by washing the surface with a commercial detergent or other suitable cleaning method. Rinse thoroughly with fresh water and allow to fully dry. All surfaces must be dry at time of application.
STEEL: Scrape and wire brush or power tool clean to remove loose rust, scale and deteriorated previous coatings. Use 7769 Rusty Primer for sound rusted or clean metal before application of a finish coat. 7780 White Clean Primer is best for clean metal, but may be used on sound rusted metal as well.
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 Stops Rust Primers are compatible with most coatings, but a test patch is suggested.
APPLICATION
Before using, stir thoroughly to ensure any settled pigment is re-dispersed. If necessary, thin the material with mineral spirits. For brush or roller, thin no more than 5% with mineral spirits. Do not thin with gasoline, lacquer thinner, turpentine, etc. Apply with a good quality brush, roller or spray gun.
Brush: Use light, even strokes. Excessive brushing reduces film thickness and protection.
Roller: A ⅜" nap roller should be used on rough surfaces. Cover approximately one square yard at a time. Roll away from the previously coated area and work back to it for a uniform appearance. Use a brush on crevices and sharp edges.
Spray Gun: Follow spray gun directions carefully. Always keep the gun ten to twelve inches from the surface and in motion while spraying.
DRY & RECOAT
Dry and recoat times are based on 70 °F (21 °C) and 50% relative humidity. Allow more time at cooler temperatures and higher humidity. Dries to the touch in 2-4 hours, to handle in 5-9 hours and can be recoated after 24 hours.
