Exterior

Tung oil transforms the unbrushed charred surface of our Suyaki® yakisugi “shou sugi ban” into a leathery texture that slows soot layer erosion, extends wood durability, and creates an even black color. This combination is suitable for exterior installations. Yakisugi heat treatment hardens and protects the siding against pests, moisture, and fire. While tung oil slows the weathering process, the siding will still develop its own a unique patina in response to the local climate over time.

Considerations

Handle with extreme care.
User-friendly material with a leathery surface that will patina slowly over time.
Blemishes and soot erosion will develop over time and are the nature of this very traditional material.
Easy touch up if scratched or scuffed.
Soot residue, caking, and abrasion damage is unavoidable and will cause the soot to blemish, especially along board edges. This is a natural characteristic of this product and can be touched up as required.
To prevent blocking between boards as well as abrasion blemishes, keep boards slip-sheeted until installation.

Patina scale

Patina Scale: 1

The Patina Scale has been developed by Nakamoto Forestry to approximate how its products will weather over time—from 0 (“less patina/more color longevity”) to 10 (“less color longevity/more patina”). However, every product weathers at a different rate due to local conditions, and the Patina Scale is intended as general guidance only, and is solely for informational purposes. Nakamoto Forestry makes no guarantees, representations, or warranties, express or implied, regarding the appearance or color longevity of its products after installation.

Dimensions

*Dimensional shrinkage after manufacture is possible due to being a solid-sawn wood product.

Finish details

Tung Oil Black

Our unique tung oil blend was custom formulated specifically for exterior Suyaki®. This oil stain penetrates into and stabilizes the delicate soot layer, making it easier to handle during installation. The black pigment makes the siding very consistent in tone. The leathery texture will blemish and weather over time, and can easily be touched up.
