eing somewhat soft, Nogal works with no difficulty with both hand and power tools. When installing the Peruvian Walnut flooring, a manual nailer, staples, and pneumatic nailers can be used without problems. It holds screws well, and it glues, stains, and polishes to a very attractive finish. It can be somewhat difficult to sand with flooring equipment because of its softness. Professional sanding and finishing is recommended. Interior Use Only.
