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.
Review: Standout product - 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.

## 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.

### ⭐⭐⭐⭐⭐ great product and dries clear! Easy to apply.
*by R***W on November 10, 2025*

Absolutely wonderful product. I was skeptical at first to purchase this item, considering I've always purchased deck stain at the local box stores. I'm so very glad I did! Works very well, easy to apply & appears is so much better than the name brand stains that only last about 3 years top! We'll see in a couple of years if the 10 years advertised holds up to the hype! Addendum: added photos and a note that 2 coats applied and still have over 1/3 of 5 gal bucket left over. The difference of shading is because of my poor power washing. Did it at night.
