Rust-oleum 9144402 Epoxy Mastic Coating 1 Gal Gloss Yellow

Product Description

The RUST-OLEUM 9144402 is a gloss-finish epoxy mastic coating formulated for direct-to-metal application on steel and concrete surfaces. Supplied in a 1-gallon can, it delivers 100 to 225 square feet of coverage per gallon depending on surface profile and application method. With a VOC content of 340 g/L, this coating is suited for industrial and commercial environments where rust prevention and durability are the primary requirements. An activator is required but not included. Licensed painters, industrial maintenance crews, and coating contractors typically apply this product to structural steel, equipment housings, and concrete floors in both indoor and outdoor settings.

This epoxy mastic is designed for rust-preventative applications on metal and concrete substrates in industrial, commercial, and heavy-maintenance environments. It performs across a wide application temperature range of 50 degrees F to 120 degrees F, making it viable across most seasonal field conditions. The coating is suitable for indoor and outdoor use, and its direct-to-metal formulation reduces the need for a separate primer coat on prepared steel surfaces.

Installation Notes

Surface preparation is critical — remove loose rust, mill scale, oil, and contaminants before application. Power down or de-energize any equipment being coated before work begins. Mix the activator with the base coat per manufacturer instructions before applying; do not apply unmixed product. Follow local regulations and facility safety protocols regarding VOC limits and respiratory protection when applying in enclosed spaces.
