There is a wide variety of Brazilian hardwood available on the market, today, which can be used to build decks, boat docks, and outdoor furniture. In the past, obtaining Brazilian hardwoods was costly and difficult, due to limited supplies. However, thanks to responsible tree farms, it is easier to obtain the type of wood you desire, such as Ipe, Cumaru, or Garapa. The responsible farming and harvesting of Brazilian hardwoods has not only helped to restore many of the lost forests in the country, but also has created a renewable source, so that future generations are able to enjoy the beauty and charm these kinds of woods bring to your projects.
Brazilian hardwoods all provide several benefits, such as a natural durability against fungus, mold, and termites. In addition, these woods do not require any sort of sealants or protectants, unless you want to retain the original natural color. If no protectant is applied, the wood will change color, with age, but will not lose its hardness. For example, Cumaru is a reddish-brown to tan, with a pronounced grain pattern, when you first receive it. Over time from exposure to the UV rays of the sun, the color changes to gray, with age, unless you apply a UV protectant and seal the wood.
Using Cumaru is comparable to other Brazilian hardwoods, like Ipe, but is normally a fraction of the cost. It provides a Janka hardness rating of 3,540 pounds, which is harder than maple, which has a rating of 1,450, or oak, with a rating of 1,360. You can use this hardwood with other types of Brazilian hardwoods to create your own unique deck designs.
