The RUST-OLEUM 238754 is a water-based, direct-to-metal (DTM) acrylic enamel coating formulated for superior corrosion and humidity resistance. Part of the MetalMax Sierra Performance line, this single-component coating applies directly to bare and prepared metal surfaces without a separate primer step, though pairing with MetalMax primer maximizes performance. It dries in approximately 30 minutes and delivers a smooth, washable semi-gloss finish in Navy Gray. With low VOCs, low HAPs, and low solvent odor, it is well suited for occupied or ventilation-sensitive environments such as schools, food-service facilities, and light industrial settings. Weight is 9 pounds per gallon unit.
This coating is designed for both interior and exterior metal surfaces, including galvanized steel and aluminum. Typical applications include structural steel, mechanical equipment housings, ductwork, piping, handrails, and other ferrous and non-ferrous metal substrates found in commercial, institutional, and light industrial environments. The formula meets USDA requirements for incidental food contact, making it appropriate for use in food-processing and food-handling facilities where that compliance matters. It is sold in gallon and five-gallon sizes to suit both spot-repair and full-project work.
Designed for direct application to metal substrates including galvanized steel and aluminum; suitable for interior and exterior use. For maximum corrosion protection, use with MetalMax DTM primer as a base coat system.
Surface preparation is critical — remove loose rust, scale, grease, and contaminants before application. Apply using brush, roller, or conventional spray equipment per standard coating practices and local environmental regulations governing VOC-compliant coatings. In occupied facilities, ensure adequate ventilation even with low-odor formulas. Allow full cure before exposing the coated surface to moisture or mechanical contact.
