Benefits


FINISHES

It is recommended to finish Arbor Wood with an exterior UV protective surface finish. Our products have minimal expansion/contraction properties and can be finished with standard products, such as paints and clear coats. Clients should expect slightly longer dry times because of the non-absorbing nature of the material. We recommend Cutek Extreme penetrating oil and UV color tones.

color change

Thermal modification changes the naturally occurring sugars in the wood resulting in beautiful, rich tones which extend through the full thickness of the material. Since Arbor Wood is still a natural product, the grain and unique characteristics of the wood remain. In an exterior environment, Arbor Wood will move to gray when unfinished and the application of a UV inhibitor helps maintain the original color.
