DESCRIPTION

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. .

FINISH DETAILS

Tung Oil

Our unique tung oil blend was formulated specifically for exterior Suyaki applications. This oil stain penetrates and stabilizes the delicate soot layer, making it easier to handle during installation. This coating also includes a black pigment to even out the surface color. The siding’s leathery texture will naturally blemish and weather over time, and can easily be retouched as desired. Not suitable for high-traffic applications. Delivered ready to install.

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.

CONSIDERATIONS

  • Offers a user-friendly exterior product with a leathery surface that will slowly patina over time.
  • Soot layer erosion will happen over time; this is the nature of this very traditional material. Not suitable for high-traffic applications.
  • Easy to touch up if scratched or scuffed.
  • Handle with care. Soot residue, caking, and blemishing (especially along board edges) are all common with this product.
  • Keep siding slip-sheeted until installation to prevent blocking between boards as well as abrasion blemishes.

MAINTENANCE

Tung-oiled Suyaki offers a true maintenance-optional product; however, it can be re-oiled every decade or so to freshen up the color. Yakisugi should never be scraped, sanded, or pressure washed. A very weak TSP or soap solution, neutral pH cleaner, or simply clean water can be applied with a cloth or soft brush to wash off pollen, dirt, and dust. Minor damage (such as scratches, dings, or areas with uneven weathering) can be spot-treated with touch up oil. Exterior siding should be hosed down regularly to keep the appearance fresh and clean.

For more detailed installation and maintenance guidance, our installation manual is available upon request. Please contact our sales team to get a copy.
