Rust-oleum 9241H Varathane Gloss Exterior Spar Urethane 1 Qt

Product Description

The RUST-OLEUM 9241H Varathane Gloss Clear Exterior Spar Urethane is a solvent-based topcoat engineered for wood surfaces exposed to outdoor and marine environments. It forms a tough, flexible film that resists moisture, sunlight, and physical wear, delivering long-lasting protection without becoming brittle under thermal cycling. The formula incorporates an ultraviolet absorber that shields the wood substrate from UV degradation. Flow and self-leveling properties allow for a smooth, glass-like gloss finish with minimal brush marks. This product is sold in a 1-quart unit and is applied by finish carpenters, marine woodworkers, and painting contractors working on exterior wood projects.

This spar urethane is suited for a wide range of exterior wood applications including siding, patio furniture, railings, exterior doors, wood boat decks, and trim above the waterline. It performs well in both residential and light commercial settings where wood is subject to direct sun, rain, and humidity. The flexible film allows the coating to move with the wood as it expands and contracts seasonally, reducing the risk of cracking or peeling over time. Commonly referred to as liquid plastic in the trade, it is a go-to clear finish for high-exposure exterior wood.
