About this product
Premium Cumaru Tongue & Groove V-Joint Boards for Ceilings and Architectural Cladding
Bring the natural warmth and rich character of Cumaru hardwood to your architectural projects. Also known as Brazilian Teak, Cumaru is a dense tropical hardwood valued for its distinctive grain, reddish-brown tones, and natural resistance to decay.

Installation & Care
Cumaru is a dense hardwood. Pre-drilling is recommended before fastening. Use appropriate corrosion-resistant fasteners designed for exterior hardwood applications and follow the installation requirements for the selected system.
When cutting or machining Cumaru, use appropriate dust protection and follow safe woodworking practices.
Cumaru naturally changes color when exposed to sunlight and weather. To help maintain its reddish-brown appearance, apply a compatible exterior hardwood oil with UV protection according to the manufacturer's instructions. Left untreated, the wood gradually weathers to a silver-gray patina.
