About the Species
Cumaru (commonly known as Brazilian Teak) is one of the world’s most durable tropical hardwoods. It is prized for its exceptional hardness, long service life, and natural resistance to moisture, insects, decay, and everyday wear.
Its dense grain and attractive golden to reddish-brown tones make Cumaru a popular choice for residential and commercial exterior projects where both appearance and performance matter.
Whether you are building a backyard deck, commercial boardwalk, outdoor living space, or architectural facade, Cumaru offers long-lasting beauty with minimal maintenance.
Unlike pressure-treated lumber or composite alternatives, genuine Cumaru hardwood develops a distinguished natural character while maintaining exceptional structural integrity for decades.
Natural Appearance
One of Cumaru’s defining features is its warm, inviting appearance.
Freshly milled Cumaru typically displays:
- Golden brown tones
- Honey brown shades
- Medium reddish brown highlights
- Attractive natural grain movement
- Fine to medium texture
- Smooth finished surface
Over time, if left untreated, Cumaru naturally weathers to an elegant silver-gray patina. Applying a quality hardwood oil periodically helps preserve its original warm color.
Its rich appearance complements both modern and traditional architectural styles, making it a versatile choice for luxury outdoor spaces
