What you need to preserve wood using the Shou-Sugi-Ban technique:
- Planks or slabs of wood that you will work with.

- Brass wire brush, sanding paper, sanding pad.
- Polyurethane based wood polish.
- Brushes for applying paint, stain and polish.
The burner must be large enough. Of course, you can work with small planks with a small burner, but if the piece of wood is large enough, a “spotty” effect can appear. The wood may not be burned evenly. With a large burner, everything will turn out much faster and more evenly..
Take a test first. The same type of wood during firing can manifest itself in completely different ways! Decide how deep you want to get fired. Black-charcoal or shallow to brown.

It is as if you are painting on wood, making movements similar to the process of painting. And you see how gradually your piece of wood gets darker. In the process, you will hear the crackling of a tree. This means that you have reached the goal, the Shou-Sugi-Ban drawing is received.
After firing, the wood must be allowed to cool, and then remove the layer of soot and carbon deposits with a brush, sanding paper. Don’t press too hard to leave streaks. The brushing depth will depend on the firing depth. Now the tree can be painted in any color using wood paint for exterior or interior use, depending on where you plan to use your finished product.
