Rust-oleum 302140 Universal Alkyd Primer 1 Gallon White

Product Description

The RUST-OLEUM 302140 is a high-solids, oil-based alkyd primer formulated for interior and exterior surfaces where optimal surface preparation is not always possible. This flat white primer delivers excellent penetration, flexibility, and stain-blocking performance on a wide range of substrates. It bonds directly to dense, glossy surfaces including enamel paints, varnishes, paneling, laminates, and ceramic tile without sanding or de-glossing. The 302140 qualifies as a direct-to-metal (DTM) coating and recoats in under 2 hours, making it well suited for production painting schedules on commercial and residential projects.

This primer is intended for trade professionals handling interior and exterior painting work on surfaces where adhesion is a challenge. Painters, contractors, and maintenance professionals use it on glossy or hard-to-prep substrates such as tile, laminate, and previously painted enamel surfaces. It is available in a 1-gallon unit and also in a 5-gallon container for larger jobs. The high-hiding, high-solids formula reduces the need for multiple coats before topcoating.

Installation Notes

Application should be performed by qualified painters or coating contractors following local VOC regulations and applicable safety codes. Ensure adequate ventilation when applying oil-based coatings in enclosed spaces, and use appropriate respiratory protection per the product safety data sheet. Clean all tools and equipment with paint thinner immediately after use.
