Rust-oleum 330144 Universal Alkyd Primer 5 Gal Metal Gray

Product Description

The RUST-OLEUM 330144 is a high-solids, oil-based alkyd primer formulated for interior and exterior application when optimal surface preparation is not possible. Available in a 5-gallon pail in Metal Gray with a flat finish, it delivers excellent penetration, flexibility, and stain-blocking performance on a wide range of substrates. The formula bonds to dense, glossy surfaces including enamel paints, varnishes, paneling, laminates, and ceramic tile without sanding or de-glossing. It also functions as a direct-to-metal (DTM) coating, making it a practical choice for professional painters, maintenance contractors, and industrial coating applicators working across multiple surface types.

This primer is suited for both residential and commercial projects where surface conditions vary or prep time is limited. Its high-hiding formula allows topcoats to cover more uniformly, reducing overall material use. The fast dry time supports efficient workflow in occupied facilities or time-sensitive job sites. Cleanup is performed with standard paint thinner, keeping the process straightforward for trade professionals in the field.
