Nothing beats the beauty of real wood. RainScreen siding of Ipe, Purpleheart, Massaranduba and other premium hardwoods are unique in appearance and many choices are available for color preference. No other siding material compares to the natural beauty and character of Brazilian Hardwoods.
About Cumaru Siding
Cumaru (pronounced Koo-Mah-Roo) is world-renowned for its superior characteristics and properties. You may have heard of Ipe’s incredible hardness, durability, and longevity- Cumaru is similar to Ipe in many ways and is often used interchangeably with Ipe. Cumaru is one of the hardest woods in the world which lends to its incredible durability and longevity. It is also naturally resistant to insect attack, mold, rot, fire and decay.
Color and Appearance- The sapwood of Cumaru(red) hardwood – RealCumaru – hardwood siding lumber is very similar to the heartwood, which ranges from red brown to deep red in color with a tight, even grain. Over time the red cumaru color will “flatten out” slightly. The species has an irregular, slightly interlocked grain and is coarse and wavy in texture. This dense, attractive Brazilian hardwood has the characteristics of ipe, but without the olive-green tone.
Benefits of Cumaru Siding
Finishing and Maintenance
Whether to oil your Brazilian Hardwood Siding or not, is only a matter of preference. To apply oil, use the same methods for oiling a Brazilian Hardwood Deck, in the video. The process is exactly the same, but cleaning is significantly reduced. Siding boards are installed on a vertical surface so the amount of dirt that is collected is far less than decking. RealRainscreen Siding may only require oiling every few years to maintain the color. Cleaning may not be necessary for 4-6 years after installation. The preferred oil for Cumaru and other Brazilian Hardwoods is, Messmer’s UV Plus Natural.
Over time, without oil, the boards will fade into a beautiful grey and silver. How long that takes is a matter of directional facing and sunlight exposure. For those looking to achieve a rustic, silvery, or reclaimed wood look with outstanding longevity, simply do not apply the oil. In a matter of weeks, the boards will begin to fade from browns to greys.
Additional Cleaning and Oiling Tips:
- Do not use a pressure washer on Tropical hardwoods like Cumaru; Follow the cleaning instructions outlined in the Cumaru Deck Maintenance Video, above
- When Oiling, always start with a cleared surface: clear of dirt, dust, debris, and furniture
- Use a brush, rag (like an old cotton T-Shirt), a Deck Pad or a Deck Boss to apply oil: Do NOT use a roller
- Only ONE (1) thin coat of oil leaving no excess; Do NOT apply a second coat
- Allow at least 12 hours to dry; It must not rain within 12 hours of oil application
Working with Cumaru Siding
Utilizing spacers or stickers between boards to allow air movement and natural drying also aids the acclimation process. Always store materials flat and keep dry and covered prior to installation. Installing wet or saturated boards may result in shrinkage. Refer to the Siding Installation document for more information.
Real Rain Screen™ installation requires furring strips fastened to exterior walls over a vapor barrier. Siding is fastened to furring strips – most commonly with 16” centers. Our coated aluminum H-clips are installed using our Magni 599 rust and saltwater resistant coated square drive screws. This installation provides channels in the walls, which allow the siding to breathe eliminating moisture and minimizing thermal transfer. For additional installation information, refer to the Siding Installation document.
Entrapped moisture is not only a problem in wet climates. Even in dry areas, moisture trapped in a wall system can result in rot, rust, and mold. The structural integrity of the wall is at stake, as is the health of the occupants. Proper installation is crucial to the effectiveness of Real Rain Screen™.

What affect does the sunlight have on the siding?
A: Sunlight has a greying effect on these woods. Messmer’s UV Oil can be applied to significantly reduce this process.
