Great wood seal!

Great product! Photo shows the top board, which has been treated with this seal and the lower board which is untreated. The seal went on easy and really brightened up the boards it was applied to.

High end product built to last!

10 days ago

We used this product on a new deck we built and we couldn’t be happier with the results! It went on smoothly, enhanced the natural beauty of the wood without changing the color too much, and gave us confidence that the deck is protected. You can tell this is a high end product built to last!

Brighten up beautiful wood

Awesome finish on my planter boxes to bring out the beautiful clarity of the wood. Adhesion was fast making it weatherproof. Texture is very moisturizing.
