Introduction to Cumaru Decking
If you’re searching for a high-quality decking material that combines durability, beauty, and low maintenance, Cumaru decking is an excellent choice. Native to Northern South America, Cumaru wood is renowned for its exceptional hardness, natural resistance to the elements, and stunning appearance, ranging from golden tan to reddish-brown with dark grain accents. Whether you’re building a residential deck, a commercial boardwalk, or outdoor furniture, Cumaru decking stands the test of time, offering a lifespan of 25–75 years or more under proper conditions.
Why Choose Cumaru Decking?
Cumaru decking offers a unique combination of durability, strength, and aesthetic appeal, making it a top choice for outdoor spaces. Here are the key benefits:
Durability and Strength
- With a Janka hardness of 3,540 lb, Cumaru wood is one of the hardest woods globally. This contributes to its longevity, with some applications lasting up to 100 years for fence posts and earth contact timbers.
- It has a high load capacity, ensuring it can support heavy furniture, grills, and foot traffic without sagging or bending.
- The dense structure provides a solid platform that withstands weather extremes, with minimal expansion and contraction.
- Natural resistance to rot, insects, decay, and fire (Class B rating) makes Cumaru decking ideal for outdoor use.
Beauty and Style
- The wood features warm, rich tones ranging from golden tan to reddish-brown, often with dark grain accents that add character and depth.
- Over time, untreated Cumaru decking develops a natural silvery-grey patina under UV exposure, which can be restored with UV-protective oil if desired.
- Its versatility complements a variety of architectural styles, from modern and sleek to rustic and natural.
Low Maintenance
- Cumaru decking requires minimal upkeep, needing only periodic cleaning with a mild detergent and water to remove dirt and debris.
- For color preservation, applying a UV-protective oil annually is suggested, with deeper cleaning every 2–3 years using a wood cleaner-brightener.
- Unlike composite or pressure-treated lumber, Cumaru does not require regular sealing or staining and does not develop raised grain.
Cost-Effectiveness
- Cumaru decking is more affordable than Ipe while offering similar durability, strength, and aesthetic appeal. It’s a budget-friendly choice for both residential and commercial projects.
How to Maintain Cumaru Decking
- Cleaning: Use mild soap and water periodically to maintain its appearance.
- Oiling: To preserve its color, apply UV-protective oil once a year.
- Natural Weathering: If left untreated, Cumaru will weather to a silvery-grey patina over time.
