Shou Sugi Ban procedure 2

[dik]

I have a thread in the Wood Design forum, trying to get information about this process. Can anyone verify that it's a valid procedure?

Thanks Dik

I saw a short video on it on TV about a year ago. It was a sales video for siding I think. Didn't pay much attention to it but if it is a fake, they spent a lot of money on a video. It may have been one of those DIY shows. There is a lot about it on the Internet, but as always, take it with a grain of salt. I have never saw any sales paraphilia say anything bad about any product.

Had an architect raving about it, but when I asked, he had never laid his hand on any, nor seen it firsthand, seems he was just "being an expert from a distance".

For fear of invoking the wrath of AI, here is what Chat thinks, (unedited as always)


Shou Sugi Ban (焼杉板, Yakisugi) is a traditional Japanese wood preservation technique that involves charring the surface of wood to make it more durable, resistant to insects, and weatherproof—while also giving it a striking, textured, and often blackened appearance.

Key Facts:​

• Origin: Japan, historically used on exterior siding, especially for cedar.
• Process:
  1. Charring the surface (traditionally with an open flame).
  2. Cooling the wood.
  3. Brushing to remove soot and expose the grain.
  4. Oiling (typically with natural oils like tung oil) to seal and enhance the finish.

Benefits:​

• Durability: Resistant to rot, insects, and UV damage.
• Low Maintenance: Once finished, it doesn't require frequent resealing.
• Aesthetic Appeal: Deep blacks, silvers, or brown tones with prominent grain patterns.
• Eco-Friendly: No chemicals needed—just fire and oil.

Modern Use:​

Shou Sugi Ban has made a major comeback in modern architecture and design for:

• Exterior siding
• Interior walls and ceilings
• Furniture and accent pieces

While traditionalists use Japanese cedar (sugi), it can be applied to woods like pine, spruce, cypress, or oak—though results vary based on wood type.

Do you know if there has been any testing to show the improvement? or effects on other wood products?

here is something from the USDA Forest Service, way too many graphs for me.
