Rust-oleum 340651 Dtm Acrylic Enamel 1 Gallon Satin Masstone

Product Description

The RUST-OLEUM 340651 is a water-based, direct-to-metal (DTM) acrylic enamel coating designed for indoor and outdoor metal surfaces. It bonds directly to bare metal without a primer, delivering excellent corrosion resistance with one-coat coverage in a satin finish. The masstone base formulation dries to the touch in approximately 15 minutes, making it a practical choice for industrial maintenance painters, facilities crews, and trade contractors working in environments where downtime matters. It weighs 9.09 pounds per gallon and is sold in single-gallon units.

This coating is suited for metal surfaces in mild to moderate corrosive environments, both indoors and outdoors. Its low-drag application characteristics make it compatible with brush or roller application, producing a consistent, even film. The formulation meets USDA requirements for incidental food contact and is accepted for use in federally registered Canadian food facilities, making it appropriate for food processing and institutional environments where coating compliance is required.

Compatibility

Designed as a direct-to-metal finish coat for bare or prepared metal surfaces in residential, commercial, and light industrial maintenance applications. Apply when ambient temperatures are between 50 and 100 degrees F and relative humidity is below 95 percent.

Installation Notes

Surface preparation is critical — remove loose rust, grease, and contaminants before application. Licensed painters and industrial maintenance crews should follow local VOC regulations and applicable safety codes when applying water-based coatings in enclosed spaces. Ensure adequate ventilation during application and drying. Do not apply to surfaces outside the recommended temperature and humidity range, as adhesion and film formation will be compromised.
