Considerations Toggle icon
  • Easily touch up field cuts or damage with water-based polyurethane tinted black.
  • Can be ripped, back-planed and glued up for interior door or cabinet applications.
  • Non-toxic polyurethane coating.
  • Not suitable for any exterior applications or prolonged exposure to moisture.
  • Soot residue, caking, and abrasion damage is unavoidable and will cause the soot to blemish, especially along board edges. This is a natural characteristic of this product and can be touched up as required.
  • To prevent blocking between boards as well as abrasion blemishes, keep boards slip-sheeted until installation.
Dimensions Toggle icon
*Dimensional shrinkage after manufacture is possible due to being a solid-sawn wood product.

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.
