The Kebony Use & Maintenance Guide (PDF) provides practical instructions for caring for Kebony decking, cladding, and roof boards after installation. This guide explains how Kebony behaves outdoors, how to properly clean and maintain the surface, and what homeowners and installers can expect as the material ages.
The document begins with product safety information (page 2), confirming that Kebony is not toxic to humans or the environment during use or disposal. It also outlines approved applications for above-ground exterior uses where durability and low maintenance are important. Because Kebony is made from sustainably sourced wood and bio-based input chemicals, it provides long-term stability without ongoing chemical treatments.
Dimensional stability notes on page 2 explain that swelling and shrinkage will occur with moisture changes, but far less than untreated wood. Kebony Character may swell up to 6% of board width, while Kebony Clear swells about 4%. These values guide installers on spacing expectations and help homeowners understand minor seasonal movement.
Page 3 discusses long-term appearance. Kebony starts with a deep brown tone and gradually transitions to a silvery gray patina. The rate of graying depends on sunlight, weather exposure, and local conditions. This natural color change does not affect durability, and customers may apply oil, stain, or paint if they want to retain or alter the color.
Cleaning and maintenance guidelines on page 3 cover routine brushing with water to remove dirt and debris. Surface mold or algae can be washed away using household detergents suitable for outdoor cleaning. Heavily stained boards may require cleaners containing oxalic acid, though manufacturers’ instructions should be followed closely. High-pressure washers may be used only with appropriate brushes, never directly on the wood surface.
The guide also outlines metal-contact considerations, noting that water runoff from Kebony can discolor zinc or copper, and that non-stainless fasteners may cause rust stains. A butyl tape barrier is recommended in these situations. Page 3 concludes with storage recommendations to keep boards covered before installation.
