Using proprietary nanotechnology, it penetrates deep into wood fibers to create a flexible, breathable, and UV-stable barrier that prevents water damage, decay, mold, and warping. Safe for use over open water and non-toxic to aquatic life, it preserves the natural beauty of wood without film formation or peeling. ## Description SEAL-ONCE MARINE Premium Wood Sealer protects and stabilizes wood against water damage and decay. It uses proprietary nanotechnology to penetrate, coating the wood fibers at the cellular level. The advanced technology of MARINE allows it to form a superior barrier below the surface, protecting from the inside out.MARINE allows wood to age naturally without decay, and can be used to preserve old or new wood, extending its natural life. It is non-film forming and will not alter the natural beauty of the wood. It can be applied around or over open water, without harming marine life. MARINE preserves the integrity of the wood by inhibiting warping, cupping, rot, mold, mildew and algae growth. MARINE forms a flexible breathable barrier that allows the wood to expand and contract, and for water vapor to escape. MARINE goes on milky white and dries clear. It is also available in semi-transparent tints. Recommended Applications• Decks • Docks • Railings • Piers • Retaining walls • Outdoor furniture. Available in 11 semi-transparent color tints. Choose from Battleship Gray, Black, Bronze Cedar, Brown, Cape Cod Gray, Cedar, Light Brown, Mahogany, Natural, Redwood & Shale Gray. Typical sealers form a barrier on the surface, trapping moisture below the surface. As water evaporates, it causes the surface coating to crack & peel, leaving a surface that requires continued maintenance. SEAL-ONCE protects against water damage, using proprietary nanotechnology that penetrates deep into the wood and bonds to the wood fibers and cells at a microscopic level. SEAL-ONCE protects from the inside out to provide unparalleled protection & stability for wood. The flexible, breathable barrier created by SEAL-ONCE, allows water vapor to escape while preventing damage caused by water intrusion. Review: Looks fresh and new - Im in central FL and had this playhouse in the elements for maybe 1 week with heavy rain twice. 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: First photo, applied and second photo, half still raw and half applied and dry. - 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. ## Features - MARINE SEALANT: Our liquid formula creates a UV-stable coating for protection against the elements, saltwater spray, and water damage.

I purchased Seal-Once Marine Penetrating Wood Sealer (clear) in June 2023, 3 years ago, and applied it to a large gazebo (from Costco) on my deck. Seal-Once has done a phenomenal job of protecting the wood, and the gazebo still looks almost new. My experience with prior brands of sealer/waterproofing caused me to do a lot of research while selecting which protection to use on my new gazebo. I live in sunny California so sun damage was my primary concern, but we average 54” of rain annually so I was also looking for water protection too. I have been pleasantly surprised that this product has really surpassed my expectations. I am a very satisfied customer and will continue to use Seal-Once Marine Penetrating Wood Sealer. (The attached photo was taken right after the gazebo was first installed.) ## 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.sn/products/383547569-seal-once-marine-penetrating-wood-sealer-and-waterproofer-clear-1](https://www.desertcart.sn/products/383547569-seal-once-marine-penetrating-wood-sealer-and-waterproofer-clear-1) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-30*
