The RUST-OLEUM 315509 is a fast-drying, water-based direct-to-metal (DTM) acrylic enamel coating in Forest Green gloss finish, sold in a 1-gallon container. This coating bonds directly to bare or lightly oxidized metal without a primer, delivering excellent one-coat coverage and strong corrosion resistance. It is formulated for both indoor and outdoor applications in mild to moderate exposure environments. Dry time is approximately 15 minutes, making it well-suited for projects where minimizing downtime matters. It weighs 9.09 pounds per unit. Licensed painters, maintenance contractors, and facility maintenance professionals are the primary installers.
This DTM enamel is designed for direct application to metal surfaces in commercial, industrial, and institutional settings. Typical use cases include structural steel, equipment housings, machinery, piping, and metal fixtures. It is approved for use in federally registered Canadian food facilities and meets USDA requirements for incidental food contact, making it appropriate for food processing and food service environments. Application by brush shows very little drag, and roller application produces a smooth, even finish.
Designed for direct application to bare metal, lightly rusted metal, and previously painted metal surfaces in indoor and outdoor environments exposed to mild to moderate conditions.
Surface preparation is critical — remove loose rust, grease, oil, and contaminants before application. Apply only when air and surface temperatures are between 50 and 100 degrees F and relative humidity is below 95 percent. Follow all local regulations and facility safety requirements when working with coatings in food-adjacent environments. Allow full cure before returning surfaces to service or exposing them to moisture.
