Nichiha NichiBoard 8-1/4" Fiber Cement Lap Siding pre-finished in a natural wood stain color using a proprietary process that cannot be duplicated in the field. This material has been factory finished to our color Beechnut which is a light yellow/brown color with dark accents. The deep wide cedar grain texture on the NichiBoard allows the darker accents to collect which provides a unique simulated wood finish. The satin sheen of the finish helps with the realistic tone on the final product making it look like real wood without all of the maintenance.
