Our Unfinished Dutch-Haus® MRP® Wide Plank Flooring comes pre-sanded with 120 grit, a smooth face and 2-sided nano bevel. The tongue and groove planks are conveniently bundled and ready to site finish with your choice of products. While we highly recommend using renewable hardwax oil that never needs sanding, the versatile surface of our flooring will receive stain, oil, wax, polyurethane or water-based lacquer finishes equally well.
