One goal of a Green floor care program is to minimize the number of floor refinishing cycles. This reduces the amount of chemical, water, and waste necessary for the task. And, one way to do this is to increase spray buffing frequencies.
According to  Daniel Frimml, a technical service representative with Tornado Industries, spray buffing also helps restore a floor's luster.
"The process involves misting small amounts of finish, typically diluted with water, to the floor and then polishing with a standard, low rpm buffer with buffing pad attached."  
However, to be safe and effective, spray buffing must be performed properly. Start with a quality floor machine, preferably one with reduced torque and vibration, because "spray buffing takes time, and this helps reduce [worker] fatigue," says Frimml.
Other suggestions, applicable to a variety of hard-surface floor coverings, include:
• As with all floor care tasks, place "wet floor" signs around the work area
• Dust mop/vacuum the entire floor area to be spray buffed; if dust mopping, start at the perimeter of the floor and work inward
• Damp mop the entire area and allow to dry
• Lightly mist a section of the floor-two to four feet in front of the machine and six to eight feet wide-with finish
• Do not mist directly onto the floor, but over the entire area to be treated; additionally use as little spray as possible to perform the task satisfactorily
• Machine buff the area at least twice, preferably three or four times-the first pass spreads the finish over the floor and additional passes clean the floor, removing heal marks, stains, and producing the desired gloss 
• Buff using a pendulum motion, from left to right and then right to left.
"A couple of things to remember," adds Frimml. "For heavily soiled areas, make the passes slower, allowing more agitation to loosen and remove soils.  Also, change the pad frequently since its effectiveness declines as it becomes more soiled."
