8 Things to Know About Adding a Cumaru Deck

You’ve made the choice to go with Cumaru hardwood decking. Here are eight important things you should understand about costs, requirements and other considerations for using this beautiful tropical hardwood for building.

Cumaru Deck

In the design world, the buzz word now is outdoor living, and according to the American Institute of Architects, many are voting for outdoor kitchens as being the most wanted amenity. And, because a great way of enjoying the fresh air and sunshine is by extending your living space outside, this makes sense. However, when you don’t have an inviting space, it’s difficult to want to spend time outdoors.

Therefore, a charming Cumaru hardwood deck is the perfect way of turning your backyard into a tranquil oasis as a solo retreat or for entertaining. If you’ve picked a Cumaru deck, you likely already know about all the benefits of using Cumaru, including:

  • Mold and mildew resistance
  • Fire rating (same as steel and concrete)
  • Longevity
  • Eco-friendliness

Even so, there are still some things you should understand about your new deck.

  1. Did you Purchase the Right Kind of Cumaru?

    Cumaru is a kiln dried wood. It’s important Cumaru is dried properly since it gives stability to the wood, which determine if your deck will warp or not. Cumaru decking boards are specifically dried for use outdoors.

    There’s also Cumaru that’s kiln dried to use indoors, but when using Cumaru outside that’s intended for interior use, it will expand, ruining your project. This goes for the use of Cumaru decking indoors when it was kiln dried for outside but is installed indoors; it will shrink. Therefore, it’s essential when ordering your Cumaru to specify you’re building an exterior deck and ask how the Cumaru was dried.

  2. The Materials Used for Structure Are Essential

    If you chose Cumaru hardwood for your decking needs, it’s likely because aesthetics and quality are important to you. It’s essential you use top of the line hardware when building your underlying structure in order to protect your investment. We suggest you use hardware designed specifically for tropical hardwood use. For instance, DeckWise makes special hidden fastener clips and stainless steel screws for hardwood decks. They also make Cumaru plugs (ribbed or smooth) for face screwing decks. These plugs are made of Cumaru. They’re simple to glue over stainless-steel screws for creating a seamless look across the deck.

    For all your wood connectors, we highly suggest Simpson Strong Tie. The structural integrity of your decking won’t just extend the life of your deck, but will also ensure a stronger and safer deck. Therefore, when placing your Cumaru order, make sure you order all required hardware for installation as well.

  3. Plan Out Shade, Lighting and Accessories Prior to Starting

    They say the proper lighting is everything and decks aren’t any different. You can set a relaxing mood outdoors with ambient lighting. Good lighting is also essential for safety. Besides you really wouldn’t want to walk up or down your Cumaru stairway without railing or stair lighting. Lighting around or over your deck will increase how much time you spend on your deck as well.

    or instance, if you want to grill on your Cumaru deck, you should think about how you’ll light your grill (nobody wants to have to hold a flashlight over you while you’re grilling). It’s essential you speak with your deck installer regarding your lighting plan so the electrician won’t need to tear a bunch of your Cumaru deck boards out later. Before you have your Cumaru deck installed, discuss:

    • Ambient lighting
    • Safety lighting
    • Task or functional lighting

    Not only should you consider the way your deck will feel and look at night, but you should also consider how it will during the day too, particularly during the hottest part of the day. Fortunately, Cumaru doesn’t become hot in the sun like some metal or composite decks do, which is the perfect reason for choosing Cumaru in and of itself.

    Finding the proper way of shading your Cumaru deck is essential not just to make you comfortable, but to also protect your deck. Although harsh sunlight doesn’t damage Cumaru, it still fades the color to silver gray from its original brownish red. You may want to think about installing a Cumaru pergola over a portion of your deck or the entire thing or at least consider using a sun umbrella.


  4. You’ll Require a Permit

    Every city has rules and regulations governing whether you’re able to build a deck and how you should build it. You can save a great deal of money and time by visiting your local building department as you wouldn’t want any unexpected surprises after you’ve build your Cumaru deck. The city doesn’t have different rules for building a Cumaru deck over one built from other materials. However, they will let you know about any variances and setbacks needed from your property line to the road or sidewalk. They’ll also have an inspector come out to check the framing underneath your deck. This is a good step to ensuring the longevity and safety of your Cumaru deck.

  5. Prep the Area Underneath your Deck to Prevent Weeds

    If your deck is being installed over dirt, make sure you spray the area with an herbicide and then cover the ground with a plastic or black fabric covering to ensure unwanted weeds don’t start appearing from underneath your deck. It’s simpler to take care of unwanted plants and roots before you build your deck. A charming Cumaru deck that has greenery coming through its boards isn’t a situation you want to deal with. You may even want to pour some gravel underneath your deck to help deter animals from making their nests under it.

  6. Properly Maintain your Cumaru Deck

    The type of maintenance and how often you maintain your Cumaru deck will depend on things like:

    • If your deck is covered
    • Where you live
    • If your deck is near a pool
    • If your deck is near the ocean

    If your Cumaru deck has direct sunlight exposure for over four hours daily, if it’s near water and/or if it’s under a tree that drops a great deal of foliage, you’ll probably want to have your deck serviced a minimum of twice a year.

    You’ll need to pressure wash and re-oil your Cumaru deck approximately every six months. If you have a pergola covering your Cumaru deck or it’s under a covered area, you may need to stain it every couple of years. When you install your deck, you should assess and observe the location you plan on installing it to ensure you take the environmental and light factors into consideration.

  7. The Cumaru’s Wood Color Changes Over Time

    The Cumaru’s beautiful auburn reddish color is a factor that makes it a favorite choice of decking for many. But, being exposed to the sun will “bleach” the Cumaru, meaning it will turn a gray color. Ipe and teak wood also take on this silver patina, as it’s called, as well when exposed to the sun. The silver patina color is very natural looking and beautiful and doesn’t change your Cumaru deck’s longevity.

    If the silver look is what you like, you won’t need to maintain your deck as much. The only maintenance required for your Cumaru deck is pressure washing. But, if you would rather it retain its original color, you’ll need to oil your deck regularly. Again, leaving your Cumaru unoiled or oiled won’t have any effect on the structural integrity of your deck’s boards, as Cumaru is naturally mildew, mold and insect resistant and won’t splinter or scratch easily.

  8. Your Home’s Value Will Increase

    Installing a Cumaru deck is a perfect way of increasing your property’s value. First, when you add a deck, you’re basically increasing the living space, particularly if you’re adding an outdoor kitchen, fire pit, outdoor seating or other accessories. By selecting Cumaru specifically for your deck material, you’re selecting a luxury building material. Installing a Cumaru deck to your home is a solid investment, both for the resale value of your home and your own personal enjoyment.

Why Choose Cumaru over Ipe?

Why Chose Cumaru Over Ipe

It can be difficult choosing which material you’re going to use for your deck, given all the options out there. However, once you dive into the decking world, you’ll find many options with different guarantees and price points such as:

  • Recycled material options
  • Plastic options
  • Tropical woods
  • Domestic woods

If you make the choice to go with a real wooden deck, the contractor will typically provide you with a couple options:

  1. Ipe deck
  2. Pressure treated deck

Fire Rating

A pressure treated deck is a more economical choice, but you’ll have a lot of issues with termites, splinters and rotting, meaning your deck will likely only last approximately 10 years. However, there are many advantages to option b, like being scratch proof, rot resistant, won’t require much maintenance, won’t splinter and it’s the most durable wood out there, lasting up to 70 years. But, while you are probably already in love with the idea of going with option b, you may not be any longer once you hear the price.

Another option is Cumaru that just may be the great compromise you need. It has all the outstanding properties and qualities of Ipe wood, but is much less expensive. So, if Ipe and Cumaru are so similar, then what really makes them different?

Cumaru has a lot of color variation and is a lighter color than Ipe. It can range from reddish-brown to a golden brown color. If you don’t oil or maintain Cumaru, it won’t become “sun-bleached” and turn to a silver patina color like Ipe would. Ipe is a darker color than Cumaru when first installed. That said, you can stain Cumaru to look darker, depending on the type of sealer or oil used.


Janka Hardness Scale

The international standard of measuring the hardness of wood is using the Janka hardness scale. Essentially, the Janka hardness scale measures a sample of wood’s resistance to wear and denting. Ipe has a high ranking, but Cumaru isn’t far behind. Ipe has a 3,510 lbf (15,620 N), whereas Cumaru has a 3,330 lbf (14,800 N) which is only a five percent difference. When you compare that to pine’s hardness of 380 lbf (1,690  N), you’ll see that Cumaru is very hard and durable.

Cumaru, like Ipe, is very durable, thanks to its natural oils and tight grain that keep rot, insects and fungus from attacking it. Some other great benefits (like Ipe) of Cumaru are:

  • It doesn’t splinter
  • It doesn’t bend
  • It doesn’t overheat in the sun

In fact, when you compare Cumaru to Ipe, it only has a two percent bending difference.


The biggest difference between Cumaru and Ipe is the price. The more cost-effective option is Cumaru. Usually, when you buy Cumaru, you’ll save around 30 percent as compared to Ipe. This can make a huge difference, particularly if you have a bigger space to cover.

Overall, Cumaru is a superior choice for decking wood. Its hardness, stability and strength make it ideal for all climates, which is why you see it a lot in subtropical and tropical areas. It’s also the perfect choice for rain screens, siding, pergolas, louvers and boardwalks. The decking boards may be milled easily for tongue and groove applications and come in various sizes. It’s a beautiful and robust wood you can trust to last and provide you with superb value for your money.
