What is Shou Sugi Ban?

If you are a skilled carpenter, you have probably already heard of it. But for those planning to learn DIY, this Japanese term might still be unfamiliar.

Shou sugi ban is nothing other than a wood burning technique. Many confirm that it originates from Japan. It aims to cause combustion on one visible side of the board in order to optimize its resistance.

Thanks to the shou sugi ban wood treatment, the material tolerates water, insects, mold, UV rays, fungi, as well as fire.

It should be noted that the majority of Japanese buildings are made of wood.

The inhabitants fear bad weather as well as the spread of fire during a blaze. The carbonized layer, using the ancient Japanese technique shou sugi ban, slows down the spread of flames.

The method is not limited to Japan. Although it is not new, it is currently enjoying immense success all over the world, especially in Europe.

Shou sugi ban wood is distinguished by its black appearance. It is widely used for the exterior cladding of a house. This type of wood siding brings an unmatched aesthetic note to the construction.

How is the Shou Sugi Ban Technique Performed?

As we just mentioned above, the shou sugi ban technique has been used for a long time, even dating back to prehistoric times. To carry it out, you can choose between the traditional method and the modern one.

The first involves building a triangular tube using 3 wooden boards. Once done, you insert the fire inside this chimney. Don’t forget to allow oxygen to pass through to optimize the combustion effect.

That said, now spread out the boards and scrub them with a brush. This removes all impurities. To finish, spray water to stop the carbonization.

It must be admitted that this traditional wood treatment requires skill and experience. If you are still a beginner, it is better to opt for the modern method.

As for the latter, the blowtorch wood technique is the most common. Unlike the wood chisel, the plane, the mallet, or the wood lathe, the blowtorch is not only used for woodworking.

It is mainly used for thermal welding or cutting metal parts. Versatile, the blowtorch is also necessary to carry out the shou sugi ban wood technique.

Prefer a propane model with torches. It ensures optimal flame control. The temperature of the latter must reach 250 to 500 °C for the carbon to form.

It is advisable to work outdoors to avoid fire risks. Don’t forget to wear special fireproof gloves. As a precautionary measure, keep a fire extinguisher nearby.
