    Finish Details - Polyurethane finish

    The non-toxic interior polyurethane coating is clean and hard and protects the wood from dirt and abrasion. It can easily be wiped clean with a moist cloth or touched up with most water-based polyurethanes. It is not suitable for exterior applications or where the siding is consistently exposed to moisture.

    Suyaki® is the most traditional and dramatic of our yakisugi “shou sugi ban” products. Its thick, hydrophobic, UV-inhibiting soot layer ensures fantastic color and wood longevity for exterior installations. Unoiled Suyaki has an E84 class A fire resistance. Our finish-coated Suyaki products for interior applications look similar to our exterior-installed Suyaki products, but with unique tactile characteristics.

     

    Traditional yakisugi siding is made by charring the surface of Japanese cedar to enhance its durability and aesthetic beauty. Originally used to protect homes from fire, decay, and insects, it’s now a defining material in modern architecture.
