DESCRIPTION

Charred, unbrushed, and unoiled yakisugi “shou sugi ban” is as traditional as it gets. Unoiled Suyaki® provides a visual and cultural benchmark for our products. Used mostly for exterior applications, though it has also been used in Japan for interior ceilings as an air purifier. This is a great option for owners who appreciate the natural beauty of wood and siding with a unique, ever-changing patina. Leaving the charred wood unoiled allows it to naturally weather in response to the local climate. The yakisugi heat treatment process hardens and protects the siding against pests, moisture, and fire.

FINISH DETAILS

Unoiled

Yakisugi heat treatment makes a finish coating unnecessary. Unoiled siding can always be oiled in the future to add color or protection. Delivered ready to install.

Patina Scale: 2

Patina Scale Graphic rating 2 indicating More Colorfast

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

  • The original yakisugi “shou sugi ban” siding, the way it’s been done for hundreds of years.
  • Arguably the most beautiful black color there is in architecture.
  • The most fire-resistant natural wood siding that we are aware of.
  • Soot layer erosion will happen over time; this is the nature of this very traditional material. Not suitable for high-traffic applications.
  • Handle with care. Soot residue, caking, and blemishing (especially along board edges) are all common with this product.
  • Installers and the jobsite will get covered in soot dust during installation.

MAINTENANCE

This product can be enjoyed for a lifetime with little-to-no additional maintenance. 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. 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.
