Varathane Exterior Spar Urethane (Water-Based) — Semi-Gloss Dark Walnut, Quart

One-Step Exterior Stain and Spar Urethane

Varathane Water-Based 1-Step Stain and Spar Urethane combines color and protection in a single, simple step. The soap and water cleanup makes maintenance easy, while the fast dry time and low odor keep projects moving smoothly. This ready-to-use finish is designed for outdoor wood projects where color depth and surface protection matter, without the need for multiple products.

Designed for outdoor use, this formula works well on railings, furniture, trim, and boats above the waterline. It delivers a deep, rich color with a semi-gloss finish that helps protect surfaces from sun, moisture, and wear, all while preserving the natural grain for an inviting, authentic look.

Key benefits you may notice

• Stain and spar urethane in one step for a streamlined project
• Low odor and quick drying to minimize disruption
• Soap and water cleanup for easy maintenance

The product covers up to 90 sq ft per quart, enabling you to tackle small or medium outdoor projects with fewer coats. A premium formulation yields a deeper color, and you can apply additional coats to intensify the look or achieve a richer finish as desired.

Practical usage and outcomes

• Railing and deck accents gain durable color while preserving wood texture
• Outdoor furniture and trim receive a protective layer that stands up to sun and weather
• Boat surfaces above the waterline stay visually appealing and sealed

To maximize results, prepare the wood properly and apply thin, even coats. Expect a refined finish that balances color depth with a protective semi-gloss sheen. Results can vary with technique and climate, but many users appreciate the combination of color, protection, and ease of use in a single product.
