## Description

desertcart.com: Seal-Once Marine Premium Wood Sealer - Waterproof Sealant - Wood Stain and Sealer in One - 1 Gallon Natural : Sports & Outdoors

Review: This is what you need! - Wow! I couldn’t be more impressed! I searched for the perfect sealer for a live edge outdoor art piece and this one ticked all the boxes: Goes on quick and easy, low/no odor, soap & water clean up, fast drying, non-yellowing and excellent waterproofing. The best part!? It lived up to all of my expectations! The only “negative” about this product (which was actually an amazing bonus) was the clip added to the top of the gallon to prevent leaking during shipping was on tight and took some muscle to remove!! Shipping was lightening fast too!! It did an excellent job in sealing the live edge of the wood and I anticipate it will preserve it for years!
Review: Water beads up, consistent coverage, good stuff - Honestly, I didn’t know what to think. There are several negative reviews, several positive, which left me in a bit of a lurch. Do I risk it and potentially regret it, or will I be a lucky one? I went ahead and pulled the trigger and couldn’t be happier. I followed the directions to a “T”, bought the clear and then purchased the black tint separately. This stuff goes on like a dream. It’s is a bit watery, which the green painting tape didn’t completely guard against, but being water based made for pretty easy cleanup. I’ll try the upgraded paint block tape next time. We’ve had a hard rain today and this stuff had performed flawlessly. Water beads up and runs right off, the wood fibers seem very well protected/sealed, nothing to complain about as far as adhesion goes. Time will tell if it lives up to its stated duration. Honestly though, it goes on so easy and looks so good, I’m not opposed to having to reapply earlier if needed.

## 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.

### ⭐⭐⭐⭐⭐ Awesome product for sealing cedar
*by K***E on January 1, 2026*

Used this to seal our cedar deck that I built. Goes on smooth, used a pump sprayer and then went over with a paint roller. Has a milky color when first applying and then dries clear. Applied two coats back to back. Deck is about 450 square feet and I used almost two gallons. Only complaint is the handle, I had one break off while pouring product in to my pump sprayer. Beads water like crazy and brings out the beautiful color of the wood. Smooth to walk on and very easy to clean once dry.
