The RUST-OLEUM 9886419 is a high-performance, two-component direct-to-metal (DTM) urethane mastic coating formulated for demanding industrial environments. Part of the 9800 System, this 1-gallon unit delivers a high-solids, high-build finish that resists sagging and provides exceptional corrosion protection on bare metal substrates without a separate primer coat. The gloss Navy Gray finish maintains color retention even in moderate to severe industrial conditions. Licensed coating applicators and industrial painters are the typical installers for this product type.
This coating is engineered for use on tanks, towers, structural steel, metal equipment, and similar surfaces in industrial and commercial settings where long-term corrosion resistance is critical. Its DTM formulation eliminates a separate priming step in many applications, reducing labor time. The product meets USDA requirements for incidental food contact and is accepted for use in federally registered Canadian food processing facilities, making it suitable for food and beverage plant environments as well as general heavy industry.
Designed for use on metal substrates including tanks, towers, and industrial equipment in moderate to severe service environments. For best results, prime first with the HS9300 System Epoxy Primer in red or gray before applying this coating in extreme corrosion scenarios.
Application is typically performed by industrial coating contractors or qualified maintenance painters familiar with two-component urethane systems. Mix base and activator according to the manufacturer's published mix ratio before application; do not apply unmixed components. Ensure the substrate is clean, dry, and free of mill scale, oil, and loose rust prior to coating. Follow applicable local VOC regulations and ventilation requirements during mixing and application.
