What You Need to Know About Cumaru Wood

Cumaru wood, also known as Brazilian Teak, is found in Northern South America and is renowned for its durability and distinctive color.
The color of cumaru wood typically ranges from medium to dark brown, but it can also exhibit reddish or purplish hues. It may feature streaks of yellow and green, blending seamlessly with its overall brown coloration.

With an interlocked grain, cumaru wood boasts a medium texture and a waxy feel. It is known to emit faint cinnamon or vanilla-like scents during installation.

Pros of Using Cumaru Wood

When building a deck, you need a wood that withstands all weather conditions. Cumaru wood’s rot resistance is a significant advantage, as it outlasts many other decking materials like Pine, Redwood, and Cedar.
Cumaru’s excellent durability is further evidenced by its superior resistance to termites and other dry wood borers. In humid climates, it also resists mildew and mold.

Cumaru has a ‘Class A’ fire rating, indicating its fire resistance is on par with steel and concrete.

The wood’s natural resistance to decay and damage positions cumaru as a top choice for decking material.

Another advantage is cumaru’s affordability compared to other woods like Ipe, and its life span can exceed 50 years. It is also relatively low maintenance.

Aesthetically, cumaru wood is known for its appealing finish. If you are an eco-conscious homeowner, you’ll appreciate that cumaru is strong without needing harmful chemical treatments and is 100% biodegradable.

Cons of Using Cumaru Wood

Despite the advantages, there are drawbacks to consider. Cumaru’s density and interlocked grain can complicate installation.
Its high oil content can interfere with adhesives, and its silica content may dull cutting tools. Installation might require predrilling or specialized hardware.

Cumaru’s weight and hardness also make it challenging to work with.

Other Considerations When Building a Cumaru Wood Deck

Consider your budget, as cumaru wood’s price can vary due to market factors. Ensure you purchase wood that has been properly dried for outdoor use to prevent warping.
Specify that your cumaru is intended for outdoor decking to get wood treated through the appropriate drying process.

Check local regulations before building your deck to avoid compliance issues.

Choose quality hardware designed for tropical hardwoods like cumaru to ensure durability and a seamless finish.

Be aware that your deck’s color may fade if exposed to direct sunlight over time.
