Rust-oleum 9231 Varathane Gloss Exterior Spar Urethane 1 Gal

Product Description

The RUST-OLEUM 9231 Varathane Gloss Clear Exterior Spar Urethane is a tough, flexible, oil-based topcoat engineered for wood surfaces exposed to outdoor and marine conditions. The formula contains an ultraviolet absorber that resists sun damage, helping the finish resist graying, cracking, and peeling over time. Its excellent flow and self-leveling properties allow for smooth brush application with minimal lap marks. Sold in a 1-gallon container weighing 8.45 pounds, this coating is well suited for contractors and trade professionals finishing exterior millwork, decking, and marine structures. It is commonly referred to as liquid plastic for its hard, durable film build.

The 9231 is intended for exterior wood applications subject to weather, UV exposure, and moisture. Typical uses include siding, patio furniture, railings, exterior doors, and wood boat decks. It is also appropriate for trim located above the waterline on marine vessels. This product is not rated for below-waterline or fully submerged applications. It suits residential and light commercial finishing projects where a clear, gloss protective topcoat is required over bare or previously finished exterior wood.
