Rust-oleum 250141H Varathane Exterior Spar Urethane 1 Qt

Product Description

The RUST-OLEUM 250141H is a water-based exterior spar urethane finish formulated for outdoor wood surfaces. It provides a semi-gloss, clear protective coat that resists moisture, UV exposure, and weathering. Packaged in a 1-quart container, this finish covers approximately 400 square feet per gallon over smooth surfaces. It dries to the touch in 1 hour and is ready to recoat in 2 to 3 hours. Cleanup requires only soap and water, making it a practical choice for field and shop use by finish carpenters, boat builders, and general contractors working on exterior wood applications.

This finish is intended for use on exterior wood surfaces including doors, outdoor furniture, and boat trim. Its fast dry time supports efficient multi-coat workflows on job sites or in production finishing environments. The water-based formula resists yellowing over time, which is a common concern on clear finishes applied to light-colored or natural wood. It is well-suited for residential and light commercial exterior wood finishing projects where durability and weather resistance are priorities.
