Rust-oleum 313973 Hard Surface Epoxy Floor Primer 1 Gal Kit

Product Description

The RUST-OLEUM 313973 is a two-component, water-based epoxy primer formulated to improve adhesion of floor coatings over difficult-to-coat or marginally prepared substrates. It bonds to hard-troweled concrete, aluminum, and various tile surfaces where traditional mechanical or chemical surface preparation may not be practical. The 313973 ships as a 1-gallon kit in a flat gray finish and weighs 8.5 pounds. It is installed by flooring contractors, industrial painters, and commercial maintenance professionals working on interior floor coating projects.

This primer is well-suited for warehouse and commercial facility applications where top coats are applied over substrates that resist conventional primers. Typical use cases include warehouse line striping, zone marking, solid-color floor coatings, decorative floor systems, and metallic floor coating systems. It accepts top coats as early as 5 hours after application and does not require sanding as long as top coating occurs within 7 days. Compatible top coat technologies include acrylics, epoxies, and polyurethanes.

Installation Notes

Application should be performed by a qualified coatings contractor or industrial painter following the coating manufacturer's mixing and application instructions. Power mix the two components using a Jiffler or plunge mixer at 500-750 rpm for 2-3 minutes until a uniform color is achieved before applying. Do not delay application after mixing as the pot life is 90 minutes. Ensure the substrate is clean and dry before application, and confirm ambient and surface temperature requirements are met.
