Product Description

The RUST-OLEUM 353861 is a two-component, water-based epoxy primer engineered to improve the adhesion of floor coatings over difficult-to-coat or marginally prepared substrates. It bonds to hard-troweled concrete, aluminum, and various tile types where standard surface prep may fall short. Sold as a 1-gallon kit in a flat black finish, this primer is formulated for professional floor coating applications in commercial and industrial settings. It weighs 8.5 pounds per kit. VOC compliant nationwide, it is a reliable first layer for demanding floor coating projects handled by flooring contractors and industrial coatings specialists.

The 353861 is suited for warehouse floors, production facilities, and commercial spaces where hard-troweled concrete or tile surfaces require a reliable bonding layer before topcoat application. It serves as both a primer and basecoat for warehouse line striping, zone marking, solid color floor coatings, and decorative systems including metallic finishes. It accepts topcoats of acrylic, epoxy, and polyurethane floor coating technologies, making it a versatile foundation coat across a wide range of project specifications.

Installation Notes

Application should be performed by a qualified flooring contractor or industrial coatings professional.
