Rust-oleum 318289 Varathane Triple Thick Matte Polyurethane

Product Description

The RUST-OLEUM 318289 is an 11 oz aerosol can of Varathane Triple Thick water-based polyurethane in a matte finish. The formula is engineered to be three times thicker than standard polyurethane, delivering a single-coat application that builds a durable, protective film over interior wood surfaces. Fast dry time reduces project downtime, and the water-based formula allows for soap-and-water cleanup when the job is done. This product is used by finish carpenters, cabinet installers, furniture restorers, and general contractors who need a reliable clear protective topcoat applied quickly from an aerosol can.

The 318289 is suited for use on all interior wood surfaces, including furniture, doors, and trim. The aerosol format makes it practical for detail work, tight profiles, and surfaces where brush application is less efficient. The single-coat coverage claim reduces labor time on straightforward finishing jobs. Sold individually, with a package quantity of 6 units per case for stocking purposes.
