Rust-oleum 292603 Universal Acrylic Primer 5 Gal Gray

Product Description

The RUST-OLEUM 292603 is a universal acrylic primer formulated for broad surface compatibility across interior and exterior applications. This flat, gray primer bonds to metal, wood, concrete, plaster, wallboard, hardboard, glass, and tile without requiring a separate bonding coat. Its rust-inhibitive chemistry allows direct application to bare steel, making it a practical choice for metal fabrication, structural repair, and general surface prep work. The tintable formula gives paint contractors and tradespeople flexibility to match topcoat systems. Packaged in a 5-gallon pail and weighing 55 pounds, it is sized for production-volume work on larger projects.

This primer is suited for residential and light commercial painting applications where a single product must handle multiple substrate types. It performs well as a base coat before latex or oil-based topcoats on both new construction and repaint work. The mold and mildew resistant formulation makes it appropriate for high-humidity environments such as basements, bathrooms, and exterior siding. It also functions as a stain blocker, helping seal surface bleed-through before finish coats are applied.

Installation Notes

Application should be performed by a qualified painting contractor or experienced tradesperson following surface preparation standards. Clean all surfaces thoroughly before application; the manufacturer recommends using appropriate pre-paint cleaning products to remove grease, oil, and contaminants. Allow primer to dry fully before applying topcoats, and follow local VOC regulations and applicable building codes for surface coating applications. Do not apply to surfaces exposed to temperatures outside the product-recommended range without confirming suitability.
