## 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: One of the best products I found for water proofing wood. Just amazing. And super easy to apply.
Review: I purchased this product to refinish my small teak table for our patio and two wine barrels I’m restoring. I sanded the old finish for the table with 150 grit paper followed by a finish sanding using 220 grit. I used a small synthetic brush to apply the product. Following the instructions I applied the first coat being careful not to apply too much to avoid ponding. It went on smoothly, I applied a second coat after 15 minutes or so, as instructed on the label. It restored the teak to the original color and beauty. I was able to refinish the top of one of my barrels using the same procedures, except only one sanding with the 150 grit. It turned out great. It was easy to clean the brush as this is a water based product. I found Seal-Once to be a great value for the money. Time will tell how durable it is but I’m confident it will be.

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.

### ⭐⭐⭐⭐⭐ Review
*by H***Y on 13 July 2025*

It isn't cheap but far less expensive than rebuilding or repairing my sea side deck. As an 80 year old when I say that it is easy to apply, it must be super easy. The twenty minute drying time between coats is a real boon; by the time you get to the end of the project with the first coat, you can immediately start applying the second without doing a clean-up. The salt ocean air and the rain from the Japanese current are tough on wood so a marine finish is the way to go.
