I Love my Golden Balau deck

I was a little unsure which product I wanted to use on my new deck. But Jason and the team at Ghent helped guide me in the right direction. My deck turned out so beautiful and the clips used to install it allowed us to not have any screws showing. I am so happy with our decision. The best part is it requires little maintenance. This was as important to us along with being beautiful. I am so happy I shopped local and got an amazing product I can enjoy for years to come.

Happiness is a Red Balau Deck

Jason and his team were super helpful with advice on how to install my deck using the QuickClip hidden fasteners. We did have to screw and plug most of the end joints to keep the boards straight.

We installed and finished our 2x12 and 2x6 Batu dock trim boards last October using ExoShield Walnut. After seven months, the material still looks perfect. Wow! This stuff really does last. All my previous experience has been with Penofin's Hardwood Formula. This finish blows it away. Thank you!

We've used a number of products here in Florida where the sun beats down on our deck and have never found a successful product. We decided to try using your Black Walnut ExoShield and it's performed much better than anything else we've tried. Tung Oil is the magic and your product is the magic! In addition, we stained our entire Cedar porch ceiling with Black Walnut ExoShield and then applied a coat of marine Spar Varnish over the ExoShield. We couldn't be happier with the results and everyone who comes over compliments us on the beauty of our porch ceiling.
