Black is a very popular colour for use in flooring. The Osmo system is one of the most reliable ways to add this colour to the surface. There are two possible results. The first is a totally black floor where the oil is applied and simply allowed to dry. The second is an antique looking floor which is what is illustrated here. After applying the Osmo black & while the oil is still not dry, the floor is buffed using polishing buffing pads under a standard speed rotary sander. The end result is a beautiful antique looking floor. See below.
