Rust-oleum 318291 Varathane Triple Thick Spray Polyurethane

Product Description

The RUST-OLEUM 318291 Varathane Triple Thick Semi-Gloss Clear Spray Polyurethane is a fast-curing, one-coat wood finish designed for interior wood surfaces. The advanced self-leveling formula builds a protective film approximately three times thicker than standard polyurethane in a single application, reducing labor time on furniture, door, and trim finishing work. The clear semi-gloss finish cures to the touch in approximately 1 hour, allowing projects to move forward without extended downtime. Coverage runs approximately 50 square feet per can. Each aerosol can weighs 1.05 pounds.

This product is suited for residential and light commercial interior wood finishing applications. Carpenters, finish carpenters, cabinetmakers, and maintenance technicians use it on furniture, interior doors, trim, molding, and similar wood surfaces where a durable, scratch-resistant topcoat is required. The aerosol delivery allows for quick, even application without brush marks. This product is not intended for exterior surfaces or floor finishing applications.
