After leaving it to dry it really dried out the cedar. Always kept it covered and only 6 months old. Glad I sealed it because it did not come sealed. This was easy to use and not messy. A little runny but worked well with a regular brush. Was able to get 2 coats on quickly since it dried fast. Dried very smooth, no problems with bubbling unless I was trying to get in the small spots and they would brush right off after a few minutes. Finish is smooth, hope this lasts. Great price and value compared to others. Review: Easy to apply. Dries quickly - For a water based sealer this is really interesting. I bought two gallons and covered both sides of decking for a 14x10 deck. Hardly put a dent in the first can. Looks promising but time will tell ## Features - MARINE SEALANT: Our liquid formula creates a UV-stable coating for protection against the elements, saltwater spray, and water damage.

No direct shower spray. Will this seal it?** A: Yes you may use it for this specific application. As suggested in a comment down bellow, you would want to make sure that it is fully cured before using the shower. Typically it would take 48 hours to cure but it may take longer depending on the environment. **Q: does this work for the interior of a sauna , safe to sit on?** A: It dries to a hard, smooth finish, is non toxic and nice to look at. Would be safe to sit on...other types of recreation may require caution. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Looks fresh and new *by M***G on 22 March 2026* Im in central FL and had this playhouse in the elements for maybe 1 week with heavy rain twice.

Looks promising but time will tell ### ⭐⭐⭐⭐⭐ First photo, applied and second photo, half still raw and half applied and dry. *by J***N on 20 June 2026* First photo is the applied product . Second photo is applied on the right side, but I haven’t gotten to the left side yet. On the applied pickets, this morning, the day after applying , it’s still feels like raw wood to the touch. Which I’m happy about , it seems like the first round soaked into the wood, but did not give it a high gloss feel .I’m using it on my back fence. Clear, first off. It’s like any other can of paint, if you open it and go straight to application without stirring it well of course it’s going to be chunky. If you shake it, yeah it’s gonna foam up. You need to stir it very well, scrape the edges. I used an extra long kitchen whisk actually, I find it mixes so much easier but a paint stick is just fine. Do it thoroughly. I dry brushed really well then power washed it and let it dry for a few days. I used a corded paint sprayer on low output, stayed the same speed and distance away, did 2-3 boards at a time, and then went over them immediately with a paint brush to really spread it out. My wood was very raw and damaged from the sun and moisture so it absorbed VERY quickly which is why I sprayed just a few at a time and went over it quickly with a paint brush to push it in and around before it soaked up. It soaked in FAST. Some I had to spray over thickly a few times because they were so sun damaged and dry and soaked it up. But it took to the wood with careful application. I got about 25 feet of 6 foot standard picket fencing done with one gallon. We get the Marin layer in the mornings here so I did it in the afternoon when the fence was very dry and still had time to try again after applying it. ## Frequently Bought Together - Seal-Once Marine Premium Wood Sealer - Waterproof Sealant - Wood Stain and Sealer in One - 1 Gallon & Clear - Pro Grade, Paint Brushes, 5-Piece, Paint Brush Set: Flat & Angle Brushes for Latex and Oil Paints, Stains, Interior & Exterior Home Improvement - Magimate Deck Brush for Applying Stain, 5-inch Paint Brush, Medium Size for Quick Decking, Fence, Walls and Furniture Paint Application, Handle Threaded for Extension Use, Multicolor --- ## 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.us/products/633923951-seal-once-marine-premium-wood-sealer-waterproof-sealant-wood-stain](https://www.desertcart.us/products/633923951-seal-once-marine-premium-wood-sealer-waterproof-sealant-wood-stain) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-11*
