Rust-oleum 250081 Outdoor Clear Gloss Spar Urethane Spray

Product Description

The RUST-OLEUM 250081 is a 12 oz aerosol spar urethane topcoat formulated for outdoor wood surfaces. Sold under the Varathane line, this water-based clear gloss finish is packed with UV absorbers that protect wood from sun damage, moisture, and general weathering. The non-yellowing formula dries fast, allowing up to three coats in a single day. Low odor and water cleanup make it practical for job-site and residential exterior finishing work. Finishing carpenters, painters, and general contractors reach for this product when a durable, clear protective coat is needed on exterior wood trim, furniture, and millwork.

This spar urethane spray is intended for outdoor wood surfaces exposed to the elements. Typical applications include exterior doors, porch furniture, railings, shutters, and decorative wood trim on residential and light commercial structures. The aerosol delivery provides even coverage without brush marks, making it well suited for detailed profiles and finished millwork where brush application is impractical. It resists scratches and maintains a clear gloss appearance over time without the amber tint common in oil-based urethane finishes.

Installation Notes

Application should be performed by a painter or finishing contractor in accordance with local surface preparation standards. Shake the can thoroughly before use and apply in a well-ventilated area, keeping the substrate clean and dry before coating. Avoid application in temperatures below 50 degrees F or in direct sunlight, which can cause uneven drying. Allow each coat to dry fully per label guidance before recoating, and do not apply over oil-based finishes without proper surface preparation.
