Walnut AB Nature Oil 111PABVAF0KE050 uses dark tones that have been mixed with warmer, lighter hues for an authentic and rustic look. These engineered planks have been crafted out of Walnut which makes them durable and ideal for busy homes. The natural oil then offers a smooth finish which looks great in any space. We recommend an extra coat of Kahrs Satin Oil Matt Appearance is applied after installation of this oiled floor. This will enhance the flooring finish and help seal the joints against ingress of dirt and moisture.
