Making Wood Last With Fire, Not Paint: A Japanese Technique

  

Shou Sugi Ban 焼杉板 (or Yakisugi) is an ancient Japanese exterior siding technique that preserves wood by charring it with fire. Traditionally, Sugi wood (cryptomeria japonica L.f., also called Japanese cedar) was used. The process involves charring the wood, cooling it, cleaning it, and finishing it with a natural oil.

It is still a popular tradition in the Okayama Prefecture of Japan. Nowadays, designers and architects use other species of wood like western red cedar, douglas fir, cyprus, pine and oak. The process involves charring the wood, cooling it, cleaning it, and finishing it with a natural oil. Although time consuming, the final product is not only gorgeous, with its rich, silvery finish; the charred wood also resists fire, rot, insects, and can last up to 80 years.
