I had the treatment applied to the decorative wooden elements on my house. The goal was to protect them from the sun but I wanted to keep the natural look of the wood. I also liked the fact that it is eco-friendly. 2 years later, my wood hasn't moved, it still looks like new!

We had the Gonano treatment applied on the patio of our café to help it resist mold. It seems to work really well! The wood has not deteriorated except normal wear and tear from traffic. Such a good investment!

I have a 300 foot wooden fence around my back yard which is constantly attacked by the sun's rays. I have to replace a few boards every year because they dry out and twist. No wood stain lasts more than 3 years. I had Gonano applied, telling myself that it couldn't hurt. I am surprised! I had a lot fewer boards to change this year and the wood stayed darker, it still looked like new!
