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.) ## Features - MARINE SEALANT: Our liquid formula creates a UV-stable coating for protection against the elements, saltwater spray, and water damage. Marine is a great protector for outdoor furniture, thermally modified wood, and boat docks. Marine is safe for use over open water and is non-hazardous to aquatic life. - DECK STAIN: It's water-based, ultra-low VOC, great for enhancing the extended life of your flooring, siding, and porch. The paint forms a water-resistant shield around wood fibers at the cellular level to help preserve the natural color. - WATERPROOF WOOD SEALER: The wood used on boat docks, decks, and retaining walls near rivers, lakes, oceans, and ponds is subjected to constant moisture. We crafted a sealer, remove stain, and finish all in one, specifically for these installations. - WOOD SEALANT: Our fast-drying protector penetrates wood below the surface, coating the wood fibers at the cellular level, which creates a long-lasting, flexible, breathable barrier. It provides a no-fuss, easy clean-up with soap and water. - SEAL-ONCE: Our user-friendly wood sealers and stains are an effective way to protect your lumber or concrete against water damage. When you use Seal-Once, you have the satisfaction of knowing our products will not harm pets, plants, or people. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00EQ89RYW | | Brand | Seal-Once | | Brand Name | Seal-Once | | Color | Clear | | Compatible Material | Wood | | Customer Reviews | 4.3 out of 5 stars 1,855 Reviews | | Included Components | SEAL-ONCE MARINE - 1 Gallon Penetrating Wood Sealer, Waterproofer & Stain.

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 ### ⭐⭐⭐⭐⭐ Jva en commander d’autre *by F***S on 30 June 2026* Bon produits pour le bois ### ⭐⭐⭐⭐⭐ An excellent wood sealer and waterproofer! *by I***T on 19 June 2026* I am returning to leave this review having 3 years of experience with this product.

Product came well packaged. It mixed no problem. I am refinishing my dock. It has never been coated and is made of cedar. I stripped the gray with 50 grit belt sander. Then these photos before and after with 2nd coat applied. It was much easier to apply with an exterior stain pad then a brush and saved alot of time using that method. Keep a brush handy though to smooth out. Not sure why the colour tints are not available here but would have loved to get the cedar color. ## 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.co.uk/products/633923951-marine](https://www.desertcart.co.uk/products/633923951-marine) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-22*
