Finishing and Custom Millwork for Kebony

Natural WoodMade to Last

Rex Lumber is a premier supplier of Kebony® – the beautiful wood recommended by leading architects. This sustainable, durable wood requires no maintenance beyond normal cleaning, making it a smart choice for your customers’ projects. Kebony has a proven performance in a variety of applications including decking, cladding, and millwork. All Kebony woods have a deep brown color that will turn to a silver-gray patina over time. The speed of this graying process depends on the intensity of exposure to environmental elements like the sun and rain combined with the type of application.

Dually Modified™ Wood for Sustainable and Long-lasting Projects

Developed in Norway, the Kebony® technology is an environmentally friendly, patented process, which enhances the properties of sustainable softwood with a bio-based liquid. The process permanently modifies the wood cell walls giving Kebony premium hardwood characteristics and a rich brown color. After exposure to sun and rain, the wood develops a natural silver-gray patina, enhancing beauty while maintaining performance.

Rot-FreeGuarantee

Rot-Free Guarantee Kebony® is 100% natural wood that is modified using patented technology to enhance its strength, durability and hardness.

Because Kebony permanently changes the wood’s behaviors, there is no need for constant maintenance; you can simply let the wood naturally gray like Ipé or other Brazilian hardwoods. Plus, Kebony® lumber features a warranty against rot for up to 30 years.

Benefits of Dually Modified™ WoodWhat is Dually Modified™ Wood Technology?

Kebony-Dual-Modification-Process Kebony® uses a patented technique to enhance the wood’s strength and longevity with a biobased liquid. During this process, the wood cell is undergoing both active and passive modification.

Active modification

The biobased liquid reacts with OH-groups present in wood and reduces the water sensitivity significantly. This reaction increases the durability of the wood.

Passive modification

The biobased liquid forms a polymer that reinforces the wood and contributes directly to the strength and hardness of the wood and gives it its brown color.

Because of this unique dually modified™ process, Kebony replicates nature and produces wood with equal or superior performance to that of tropical hardwood, in a fast and sustainable way.

Kebony: Factory Finishing for Consistency

Finishing for Kebony Wood isn’t just about appearance, it also plays a role in long-term performance and consistency.

Kebony does not require a finish to maintain its warranty. Even though it will naturally weather to a silver-gray patina over time, factory-applied coatings can be used to help maintain its original color and enhance long-term appearance.

At Rex Lumber, we apply finishing in a controlled environment to improve consistency and long-term performance. This process helps ensure even coating coverage across all material, proper adhesion to freshly milled surfaces, and reliable results from the first piece to the last.

Manufacturer Finishing Systems Application

Rex Lumber can also apply manufacturer-recommended finishing systems, including Cutek Extreme Wood Stabilizer, which is designed specifically for modified wood applications. Learn more about Rex Lumber’s finishing services here.

Cutek Extreme Wood Stabilizer for Kebony is a penetrating oil rather than a surface film, so it will not peel over time. Instead, it penetrates the wood to help reduce splitting, warping, and cupping as the material ages. Cutek also performs well in both freshwater and saltwater environments, making it a strong option for coastal and high-exposure projects.

Cutek Finish Performance Benefits

While Cutek helps stabilize the wood, it does not provide UV protection. Kebony will still naturally weather from its original brown tone to a silver-gray patina over time.

CladdingBuilt to Last

Kebony is leading the way in sustainable and long-lasting real wood cladding. With award-winning cladding projects, Kebony is the go-to for America’s top architects. Available in clear or character grade, Kebony cladding features unmatched beauty, durability, and sustainability.

Stunning Siding Kebony Wood

Featuring a rich, dark brown color, Kebony only gets more beautiful over time. After exposure to sun and rain, Kebony develops a natural silver-gray patina. Kebony’s excellent dimensional stability makes it well-suited for rain screen applications. Additional Kebony wood siding benefits include resistance to rot, fungi and insects.

Versatile, DurableKebony Millwork

Kebony Clear lumber has tremendous versatility compared to tropical hardwoods. Not only is Kebony easy to work, it is also dimensionally stable. The modification process changes the cell structure of the wood without harsh additives or glues to get in the way. For this reason, Kebony can handle heavy use on commercial benches, create stunningly intricate outdoor sculptures, or get milled down for wooden guitar picks and silverware handles.
