Rust-oleum 302139 Universal Alkyd Primer 5 Gallon White

Product Description

The RUST-OLEUM 302139 is a high-solids, oil-based alkyd primer formulated for interior and exterior use where optimal surface preparation is not always possible. This 5-gallon unit covers a wide range of substrates and delivers strong penetration, flexibility, and stain-blocking performance. The flat white finish provides a neutral base for topcoats. It functions as a direct-to-metal (DTM) coating, making it suitable for metal surfaces without an additional primer step. Recoat time is under 2 hours, supporting efficient workflow on commercial and residential job sites. Cleanup requires paint thinner.

This primer is suited for trade professionals applying coatings to surfaces that cannot be fully sanded or de-glossed before painting. It adheres to dense, glossy substrates including enamel paints, varnishes, paneling, laminates, and ceramic tile. The high-hiding formula reduces the number of topcoats needed. Applicable for both interior and exterior environments, it fits painting contractor workflows on commercial repaint projects, renovation work, and multi-surface coating applications where a single versatile primer is required.
