They bear the telltale signs of wood with saw marks and knots, but these planks are laminate—a textured melamine veneer over a high-density fiberboard substrate. The flooring is DIY-friendly and ready to walk on from the day you put it down. Sold in eight-plank bundles with up to eight different "grain" patterns per box.
