Shou Sugi Ban Tips And Tricks
The following tips and tricks prevent accidents. They can help you get started with your project.
Test First
Before you begin your project do a test run on a piece that you aren’t going to use. This can be a sample or a scrap. Just anything that it’s okay if you mess up.
In this case, you will burn a small piece of wood and then sand it. Do the stain or whatever it is you are planning on doing for the whole project. Make sure everything turns out well before beginning.
Wood Grain
Wide grains will end up with thicker lines and less contrast because the grains will be thicker and blacker. When you finish burning the wood, you might find that the wood is darker if the wide grains are raised.
For a more traditional look, medium grain is used. If they are too close together they will run together and not give a definite contrast either. You want a fairly equal amount of both raised and sunken grain.
Tree Species
Cedar is the original shou sugi ban wood because it is soft and the top burns easily and quickly. It is often used to create burned wood designs as well as stamped wood.
It works for this reason but it’s not the only option. Other options include pine and spruce, with more exotic species being great too. Check with the exact species you use in order to find out if it is a good option.
Brush The Wood
Brush the wood with the torch when you burn it. Pretend that the torch has an invisible bristle brush that you need to use on the wood. Pretend like you are lightly painting it. This can help you get the right pattern.
Sand After
You may sand the wood lightly after you “brush” it with the flame, but you don’t want to do so before. This will eliminate the texture and the uneven grain that makes the burned wood what it should be.
Instead, actually, look for wood that is texture and not sanded. Unfinished wood is perfect and the more imperfect it is, the better it usually is for shou sugi ban.
Keep Flames Short
Even if you are a foot away from the wood, you want to keep the flame short. The short flame will give a more even and easier to control burn. Long flames are difficult to control and could leave you with accidents.
Add Tung Oil
If you want a rough, rustic look then don’t do anything to your wood surface after you burn it. For a softer look that offers better protection, apply a linseed or tung oil.
The oils will give your wood surface a shiny glow and better protection. You should only have to reapply the oil once every ten years.
