Make sure you can live with the characteristics of the Brazilian cherry wood before proceeding with installation. Note that the original color of Brazilian jatoba can darken dramatically over time and with ultraviolet light exposure.
Arrange the individual pieces in advance of installation according to how they will fit on the floor. Make adjustments now, because you will not be able to swap them out once installed.
Install the underlayment as a guard against floorboard squeaking.
Place the boards onto the underlayment in the configuration that you had planned. Make sure the slats are perpendicular to the joists. Tap the flooring with a rubber mallet to lock the pieces into position.
Use the cleat gun to secure a cleat into each piece to hold it firmly in place, about every 8 inches. Place the cleat through the tongue and on every joist underneath.
