Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Protect and elevate wood with the Minwax Helmsman Warm Gloss Clear Water-Based Spar Urethane. Encased in a convenient 1-gallon container, this outdoor-ready finish brings a clear, warm-gloss look to any bare or previously finished wood while forming a flexible barrier against sun, moisture, and daily wear.

  • Clear, warm-gloss finish enhances natural wood grain with a subtle amber tone that won’t yellow over time.
  • Water-based formulation delivers easier clean-up, faster dry times, and a lower odor profile compared to solvent-based alternatives, making projects indoors or outdoors more comfortable.
  • UV resistant protection helps prevent sun fade and graying on exterior surfaces like decks, fences, railings, and outdoor furniture, while keeping interior trim looking vivid and true.
  • Flexible spar urethane film tolerates wood movement from moisture and temperature changes, reducing cracking and peeling on surfaces exposed to the elements.
  • Indoor and outdoor use—designed for a wide range of exterior wood projects as well as interior trim and cabinetry that benefit from robust protection.
  • Coverage up to 125 sq ft per gallon with a durable finish that lasts, helping you plan larger projects or multiple coats efficiently.
  • Recoat in as little as 4 hours under proper conditions, with a full cure in 72 hours for a hardened, long-lasting seal.
  • Brush-on application for precise, controlled coats on stairs, railings, doors, outdoor furniture, and more.
  • VOC level 144.46 reflects a balanced, consumer-friendly formulation that respects indoor air quality while delivering outdoor durability.

Who is this finish ideal for? DIY homeowners and professional woodworkers tackling outdoor decks, fences, and furniture, as well as interior woodwork that encounters light exposure or higher humidity. If you want a transparent finish that preserves wood’s natural character while delivering reliable UV and moisture resistance, Minwax Helmsman Warm Gloss Clear Water-Based Spar Urethane is a proven choice.

Practical tips for best results: prepare the surface by cleaning and drying thoroughly, apply thin, even coats with a high-quality brush, and space coats with light sanding between applications if needed. Use as a protective, clear topcoat over stained or natural wood to extend the life of your project and keep wood looking fresh for years to come.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
