Overview

Cumaru flooring, also called "Brazilian Teak," is one of the hardest wood floors you can buy at 3,330 lbf Janka — nearly 2.5x harder than White Oak. If you need a floor that can handle the heaviest residential or commercial traffic without showing wear, Cumaru is your answer. Its warm golden-brown to reddish-brown color and subtle vanilla-like aroma when cut make it as appealing aesthetically as it is functionally. For restaurants, retail spaces, and active family homes, Cumaru provides decades of virtually indestructible performance.

Installation Tips

1

Acclimate for 7-10 days before installation.

2

Pre-drill ALL fastener holes — Cumaru will snap standard nails.

3

Use a commercial-grade floor nailer with high PSI.

4

Maintain 3/8" expansion gap at walls.

5

Carbide-tipped blades are essential for cutting.

6

Glue-down may be easier than nail-down for some installers.

Maintenance

Sweep or vacuum regularly. Cumaru's extreme hardness means scratches and dents are extremely rare in residential use. Clean with a hardwood floor cleaner. Refinish every 15-20 years — the floor simply doesn't wear out. Natural oils in the wood may affect some finishes — use products rated for exotic hardwoods.
