Cumaru Wood: A Durable and Elegant Choice for Decking

When it comes to selecting a high-quality, long-lasting wood for outdoor projects, Cumaru wood stands out as a top-tier option. Also known as Brazilian Teak, Cumaru is a dense and durable hardwood native to South America. It is widely used for decking, siding, and outdoor furniture due to its impressive strength, natural resistance, and stunning appearance.

Why Choose Cumaru Wood?

1. Exceptional Durability

Cumaru is one of the hardest woods available, with a Janka hardness rating of over 3,300, making it highly resistant to wear, impact, and heavy foot traffic. This strength ensures that Cumaru decking and structures last for decades without warping or cracking. With proper maintenance, Cumaru wood can endure for 50 years or more, making it a worthwhile investment for any outdoor space.

2. Natural Resistance to the Elements

One of the biggest advantages of Cumaru wood is its natural resistance to rot, decay, and insect damage. Unlike many softwoods that require chemical treatments, Cumaru contains natural oils that help protect it from moisture, termites, and fungal growth. This makes it an ideal choice for humid, rainy, or coastal environments where wood is typically at risk of deterioration.

3. Stunning Aesthetic Appeal

Cumaru features a rich color palette ranging from golden brown to reddish-brown hues, with an attractive interlocking grain pattern that enhances its beauty. Over time, Cumaru can develop a silvery-gray patina if left untreated, adding a sophisticated aged look. However, if you prefer to maintain its original warmth, occasional applications of UV-protective oil will help preserve its color.

4. Fire and Slip Resistance

Cumaru wood is naturally fire-resistant, boasting a Class A fire rating, the highest rating possible. This makes it a safer choice for residential and commercial decking. Additionally, its dense structure provides excellent slip resistance, making it a great option for pool decks, docks, and other wet areas.

Installation & Maintenance Tips

• Pre-drill holes before fastening to prevent splitting due to its extreme density.

• Use stainless steel screws or hidden fasteners to maintain a clean look.

• Allow proper ventilation and spacing between boards for moisture control.

• Clean periodically and apply protective oil if you want to retain the original color.

Final Thoughts

Cumaru wood is an excellent choice for those seeking a durable, low-maintenance, and visually striking decking material. Its strength, natural resistance, and timeless beauty make it a premier hardwood for outdoor applications.
