Kebony
Kebony is a modified wood product made for exterior projects that need natural woodbeauty, strong durability, and a lower-maintenance alternative to many traditional outdoor lumber options. At Mason’s Mill, we supply Kebony decking, cladding, related hardware, and samples for architects, builders, remodelers, designers, and homeowners planning high-quality exterior projects.
Why choose Kebony for exterior wood projects?
Kebony gives exterior projects the warmth of natural wood without relying on tropical hardwoods. The product starts with sustainably sourced wood and is modified with a bio-based liquid that becomes permanently bonded inside the wood fibers, creating a stable, hard,and durable material. Kebony states that the result is suitable for exterior applications where durability, environmental credentials, and low maintenance matter.
Kebony is often considered for projects where the design calls for real wood, clean lines, and long service life. It can be used for decking, cladding, flooring, roofing, windows, doors, furniture, and design objects, according to Kebony’s FAQ documentation.

Thermory Knotty Pine — Cutek Extreme Clear Finish
Thermory Knotty Pine is Scandinavian pine transformed through a chemical-free thermal modification process that uses only heat and steam. Sustained temperatures above 190°C fundamentally alter the wood's cell structure, driving off moisture and breaking down the organic compounds that fungi and insects feed on. The result is a dimensionally stable, rot-resistant board with a warm, deepened caramel tone and the character-rich knots that give knotty pine its signature appeal (Thermory).
To preserve that warm color and extend the wood's outdoor service life, each board is finished with Cutek Extreme Clear, a penetrating oil that soaks deep into the wood fibers rather than forming a surface film. Because Cutek works from the inside out, it stabilizes the board against moisture movement — the leading cause of cupping, splitting, and checking — without peeling or flaking like traditional coatings. The clear formulation contains no pigment, so the wood will naturally silver over time while remaining fully protected. Maintenance is straightforward: no sanding or stripping required, just a clean and re-oil when the surface begins to dry out (Cutek).
Ideal for exterior siding, soffits, ceilings, porch cladding, and covered outdoor living spaces where you want the authentic look of natural wood with modern durability.

Kebony Technology
Kebony uses a patented wood modification process that combines bio-based liquid infusion with heat. The process permanently thickens the cell walls of the wood, which improves stability, hardness, and durability compared with the original wood species.
This is different from standard heat-treated timber. Kebony describes its process as bio-based liquid infusion plus heat, while heat-treated timber relies on high temperature alone. Kebony says the modification changes the wood’s cell walls, while heat treatment does not alter the cell structure in the same way.
This technology helps Kebony perform more like a premium exterior wood while using more sustainable source material. For builders and architects, that means a natural wood option for projects where tropical hardwoods may not be the preferred specification.
Frequently Asked Questions
Kebony is a modified wood product designed for exterior applications such as decking, cladding, siding, furniture, and architectural features. It uses a patented process that combines bio-based liquid infusion with heat to improve the wood's stability, hardness, and durability.
Yes. Kebony is real wood that has been modified to improve performance. It starts with sustainably sourced timber and is treated with a bio-based liquid that becomes permanently bonded inside the wood fibers.
Kebony can be used for decking, cladding, flooring, roofing, windows, doors, furniture, and design objects. At Mason's Mill, common project uses include decks, siding accents, exterior cladding, outdoor living areas, and architectural wood details.
Kebony does not require special maintenance beyond normal cleaning, but it can be oiled, stained, or painted to reduce the graying effect or change the color. If left unfinished outdoors, Kebony naturally develops a silver-grey patina over time.
Kebony can typically be cleaned with water and a brush. For mold or algae, use water mixed with ordinary household cleaning agents or detergents suitable for exterior use, then rinse with clean water.
Kebony states that high-pressure washers are generally not recommended. If used, the washer should be equipped with suitable brushes that reduce and diffuse the water jet, and water jets should never be applied directly to the wood surface.
Kebony is a strong candidate for Houston exterior projects where the design calls for natural wood, durability, and lower maintenance. It is suitable for decking, cladding, siding accents, outdoor structures, and architectural exterior details.
Kebony decking, samples, and related hardware are available through Mason's Mill & Lumber Co. in Houston, Texas. Contact the Mason's Mill team for availability, quotes, samples, and project guidance.
