After sanding, it seems to take forever for that tiny airborne dust to settle down onto the floor; that's why many contractors wait to coat until the next day, after the dust has settled. Using a box fan with a filter taped on it-drawing in dusty air and exhausting clean air-can help speed the process, trapping airborne dust instead of just blowing it around. The number of fans and filters needed depends on the size and configuration of the area.
