Finish details Toggle icon

Unoiled

Sugi is often left unoiled in clean interior applications, or in exterior applications where a patina is desired. It can also be coated by the customer with standard tradecraft before or after installation. Leaving the wood unoiled in exterior applications allows it to weather naturally, according to the local climate.

Project Highlights

OUR tutorials

Suyaki

DIY: Blemish Touch-Up

Our Yakisugi Shou Sugi Ban siding ages beautifully with minimal upkeep. It naturally develops a rich patina or can be re-oiled anytime to restore its original vibrancy. Suyaki stays black for decades, with re-oiling extending its deep color even longer.

Accessories

Our Yakisugi accessories ensure a seamless installation and lasting durability. Available as a service to customers, they require a lumber purchase but are sold separately.
