Choose the options you’d like to add to your quote request.
Is yakisugi “shou sugi ban” suitable for use on furniture? Yes, but with some key considerations. Our 30mm yakisugi “shou sugi ban” profiles are suitable for applications requiring thicker board stock. Additionally, our standard 9/16” thickness yakisugi siding can be edged and/or back-planed, then glued up as a facing. For specific dimensions and profiles, please refer to the individual product specification sheets.
We also offer unburned sugi and hinoki lumber; these products are optimal for furniture applications. Feel free to reach out to our sales team for information on currently available options. Please note that we do not do custom millwork.
Can yakisugi “shou sugi ban” be used for cabinets, doors, or table-tops? Yes. Our 18mm and 30mm yakisugi “shou sugi ban” profiles are suitable for applications requiring thicker board stock. Our standard 9/16” thickness yakisugi siding can be edged and/or back-planed, then glued up as the cabinet or door facing. For specific dimensions and profiles, please refer to the individual product specification sheets.
We also offer unburned sugi and hinoki lumber; these products are optimal for furniture and cabinet applications. Feel free to reach out to our sales team for information on currently available options. Please note that we do not do custom millwork.
We want to use Gendai on both the exterior and interior of our project. Which Nakamoto Forestry finish coating should we use for this? Or do we need separate products for the two scopes? Any of our alkyd and acrylic coatings are suitable for both exterior and interior applications. If you prefer the appearance of the linseed coating over the alkyd option, simply specify linseed for exterior and alkyd for interior. (Please note: Our linseed coating option should not be used for interior applications.)
Customers can also purchase unoiled Gendai and have their own preferred finish coating applied on-site, before or after installation.
Can I specify an interior polyurethane finish on a porch ceiling, loggia walls, or a shower ceiling? Unfortunately, no. Interior polyurethane finishes are not suitable for any kind of exposure to exterior weather, direct sunlight, or moisture. It’s important to choose finishes that are designed specifically for these kinds of exposures to ensure the proper performance and durability of our products.
We want to use Nakamoto Forestry paneling on a sauna interior. Is that okay? Our unoiled Hinoki and sugi products offer an ideal choice for sauna interiors. However, it’s important to note that yakisugi “shou sugi ban” charred wood products or any kind of oil finish or stain should not be specified in sauna applications. Please see our Hinoki Moulder Blank page for specification and ordering information.
On sauna applications there are a few important parameters to follow for best results. Make sure that the lumber is under 10% moisture content before moulding and installation. Mould into a profile that allows for dramatic swelling and shrinkage without becoming noticeable. This generally means a 3/8” long tongue and groove, with a 1/4″ or so nickel gap in the profile. Acclimate the paneling stickered in the sauna itself for two weeks under normal operating conditions before installation. For best results elevate the stickered lumber on saw horses or scaffolding towards the top half of the room to expose it to the most extreme conditions. Design in a vented screen wall assembly and install with stainless steel 15gauge or larger headed nails through the tongue. Set face nails since the fasteners get very hot to the touch.
It is important to note that sauna applications are the most challenging of all installation conditions. Atmospheric conditions can vary according to room design, heater specifications, and heater operation, especially if administered by a group. In some cases, no matter how careful the millwork or installation are executed, there can still be considerable dimensional movement and sometimes failure requiring replacement.
We want to use a product of yours coated with linseed (or tung) oil for an interior application. Is this okay? All our coatings are explicitly designated for interiors, exteriors, or both. These coatings are formulated for their specific applications—it is very important to adhere to these guidelines to ensure optimal product performance, among other reasons. We never approve exceptions to our specification sheet guidance on this subject.
