An oil based polyurethane will continue to amber and darken over time, while water based poly will remain clear for the lifetime of the hardwood floor. ... Water based poly dries much faster, and several coats (up to 4) can be applied in one day. This explains why fritz the cat who did answer this question as well is why theirs yellowed **Q: How is the viscocity out of the can, is it more like warm syrup or more like water...or somewhere in between? Thank you!** A: Maybe Slightly Thinner than warm Syrup, So probably between Warm Syrup & Water. A word of advice though, I had an extremely difficult time working with this product & had to sand and reapply many coats to get a satisfactory finish. It dries fast & if you run a brush over it after is has sat more than a minute it will create rough brush marks. Additionally if you apply more than a very thin layer it will crack similar to a crackle pattern. Unless you are putting this over a pure white background I would recommend that you use the standard "Crystal Clear" non-water based urethane. It has only a light yellow tint and is much easier to work with in my experience. **Q: Can this product be applied over an exterior wood stain?** A: In fact it can, but being unfamiliar with the product, I purchase it thinking that it's use would result in a shine. I learned that "spar" must mean something other than gloss or high gloss. I then purchased the "Minwax Gloss aerosol which gave me the desired result, although several coats were required. ## Frequently Bought Together - Minwax Water Based Helmsman Spar Urethane, Quart, Semi-Gloss - Pro Grade, Paint Brushes, 5-Piece, Paint Brush Set: Flat & Angle Brushes for Latex and Oil Paints, Stains, Interior & Exterior Home Improvement - 24 Pcs Foam Paint Brushes, Wood Handle Sponge Brushes for Painting, Staining, Varnishes, and DIY Craft Projects (1'', 2'' and 3'') --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/259896776-minwax-630510444-water-based-helmsman-spar-urethane-quart-semi-gloss](https://www.desertcart.sg/products/259896776-minwax-630510444-water-based-helmsman-spar-urethane-quart-semi-gloss) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-31*
