Rust-oleum 304588 Varathane Matte Triple Thick Polyurethane

Product Description

The RUST-OLEUM 304588 is a water-based interior polyurethane finish in a matte sheen, formulated at three times the thickness of standard polyurethane products. Its self-leveling formula allows most projects to be completed in a single coat, reducing labor time on interior wood finishing jobs. The product delivers strong scratch and stain resistance and dries quickly, enabling faster project turnaround. Cleanup requires only soap and water. This finish is intended for use by finish carpenters, cabinet makers, furniture restorers, and general contractors working on interior wood surfaces.

This polyurethane is suited for residential and light commercial interior wood applications, including furniture, interior doors, trim, molding, and millwork. Its triple-thick formulation makes it particularly useful when a durable, full-coverage finish is needed without multiple recoat cycles. It is not recommended for use on exterior surfaces or floor applications where abrasion and foot traffic demands exceed its rated performance.

Installation Notes

Application is typically performed by finish carpenters, painters, or cabinet refinishers working on interior wood projects. Ensure the substrate is clean, dry, and sanded smooth before applying; light sanding between coats is standard practice even with single-coat products if a second coat is desired. Work in a well-ventilated area and allow adequate dry time before handling or reassembly. Follow local VOC regulations and consult the product technical data sheet for surface preparation and recoat window guidance.
