In this video, I will show you how to apply polyurethane (floor finish) to hardwood floors. We will apply a water-based commercial-grade finish to black walnut wood flooring. However, this method works for pretty much all finishes and all types of wood flooring. I will show you how to roll the polyurethane on and how to brush the edges. We will also cover whether you should dunk your roller in a bucket or pour the poly onto the floor.
