I would recommend using an 18 gauge cleat nailer for this exotic species; see below from our instructions. Powernail Model: 50p FLEX Nailer (visit powernail.com for rental locations near you)
[EXOTIC WOOD NAILING TIPS]:
Tongue fracture and surface dimpling during installation is common and can be minimized by (1) Installing the flooring in
proper lighting (2) using the correct nail thickness, (3) using the recommended shoe adaptor, or (4) changing the angle of
To further reduce the occurrence of surface dimpling and tongue fracture the use of flooring nailers with a thinner 18-20 gage cleat nail may be needed for the harder exotics species.
In addition, many installers will sometimes temporarily adjust the nailer angle by applying layers of duct tape to the bottom foot plate of the nailer. The use of an over-size base or foot plate to distribute the nailing force is encouraged. If however, surface dimpling or tongue fracture occurs when nailing the denser species, drilling pilot holes and hand nailing may be required.
Use caution when fastening the harder exotics with Staplers. The drive bar in Staplers are wider and if fasteners are overdriven can act like a wood chisel, splitting tongues. Do not mix fasteners when nailing. Staples and cleats hold differently when mixed can result in irregular seasonal gapping and or movement. When face or top nailing, pick areas of the grain or pattern that would best hide touch-up fillers.
