How Carbonized Wood Is Finished

Wooden boards are burned on each side, which is usually done with a blowtorch. Using a thick brush, the carbon residue is removed from the boards and the material is washed with water.

After a dry board, it is ideal to apply non-toxic natural oils to seal it. The color is usually a very rich dark color of natural wood.  Shou Sugi Ban Wood (Yakisugi) is the process of charring wood, developed in Japan.

The final appearance is determined by the type of wood, the extent of the burn and how quickly it is brushed. Colors can be manipulated using stain instead of oil.


Durable and long-lasting: Shou sugi ban life expectancy is estimated at more than 80 years when properly maintained.

The life cycle: Wood is a renewable resource and no chemicals are required to complete. We would not like to accept the fact that the combustion process requires fossil fuels, but the ensuing life makes that sacrifice negligible.

Aesthetics: You can get a variety of beautiful colors depending on how deep you burn and how deep you are brushing, to further alter or enhance the color – and can be stained as well.

Waterproof: The combination of wood charcoal and oil make the board resistant to water and mold.


When used as furniture, care is needed depending on its use – a coffee table can take more of a beating than the other pieces. But keeping oiled wood is very simple; it takes a little more than hand-sanding if necessary, and wipe in a single coat of oil quickly.
