Shou Sugi Ban Decking - Charred Wood Boards for Outdoor Use

Yakisugi is the Japanese term connected with the traditional charring of sugi boards, and Shou Sugi Ban is the name used internationally. On a deck it gives the boards a texture that untreated timber does not have.

Deep Char is the one exception worth remembering, and Degmeda supplies brushed and oiled boards for decking — brushed boards can be used without oil, but oil is the practical choice for a surface in constant use. Deep Char keeps the carbon layer created in the furnace, and a deck is a surface people walk on, drag furniture across and clean more often than a wall. Every other finish is brushed, which takes that layer back to the grain — the styles guide explains what each one looks like and the manufacturing page covers where in the process the difference happens.

Decking is harder on timber than cladding in a way that has nothing to do with charring: boards lie flat, so water sits on them instead of running off, and the gaps between them decide whether the underside can dry. That is why detailing and drainage matter more than the finish you pick. Choosing decking timber works through hardness, movement and slip honestly, without pretending one species wins, and where charred wood decays covers what standing moisture actually does.

Once it is down, care is a choice rather than a schedule. Leave it and the colour drifts toward grey; re-oil and it returns. Decking maintenance covers cleaning and re-oiling in practice, and the oil guide covers the product itself.

Match the board to the foot traffic, the exposure and the drainage, then confirm the species, surface, profile and finish before you order. If you tell us how the deck will be used and what sits around it, we will say which products suit it.
