Walnut Flooring was used mainly for elegant interiors. One of the reasons that it was popular and so sought after is that it ages to a uniquely beautiful color over time. Walnut is easily worked with both hand and machine tools. It accepts nails, screws, and glue readily. Additionally, walnut holds both wood and metal fasteners extremely well and is perfectly suited to most finishing methods. Once the milling process is finished, Walnut Flooring polishes beautifully.
