Rust-oleum Stops Rust Ultimate Flat Rusty Metal Primer - 1 qt

Rust-oleum stops rust rusty metal primer stops rust and prevents corrosion. Apply to heavily rusted metal (use rust-oleum stops rust clean metal primer on clean or lightly rusted metal). Bonds tightly to rust to form a surface topcoats can adhere to.

Rust-oleum stops rust primers provide a sound base for the 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 the enamel finish. Not for use of galvanized steel.

For Best Results

Topcoat When Fully Dry (usually 24 Hours)

Applications

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 3/8" 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 And Recoat Times

Dry and recoat times are based on 70°f (21°c) and 50% relative humidity. Allow more time at cooler temperatures. Dries to the touch in 2-4 hr, to handle in 5-9 hr and is fully dry after 24hr. Recoat after 24 hr. Do not apply clear enamel over stops rust bright coat finish or aluminum finish.

Cleanup

Clean Brush And Tools With Mineral Spirits.

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 Surface: Remove all dirt, grease, oil, salt, and chemical contaminants by washing the surface with a commercial detergent or other suitable cleaning methods. Rinse thoroughly with fresh water and allow it to fully dry. All surfaces must be dry at the 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 the 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.

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. Clean up carefully with a hepa vacuum and a wet mop.
