The aggressive scrub is generally performed when difficult soils such as grease and oils are present or heavy build-up of floor finish needs to be removed. In the case of build-up, the aggressive scrub is performed when medium scrubbing is no longer effective and soil is deeply embedded and encapsulated in the multiple layers of floor finishes.
Performing aggressive scrubs instead of stripping the floor can be accomplished if you are providing hard floor maintenance using a preventative maintenance system. If you are scheduling all daily/routine maintenance, periodic maintenance or stripping maintenance, then you have the advantage of knowing exactly what has happened to the floor and when. If you were involved in the initial or last strip in your facility and used quality chemicals, you will be able to utilize aggressive scrubs as well.
The objective is to maintain that level of gloss without building it up or encapsulating soil. If the floor finish is a clear coating, then you will be able to maintain that level of gloss by limiting the erosive material on the floor. This can be accomplished by implementing a hard floor maintenance program. This would dictate the services to be performed, the amount of time required for them to be performed in and the frequencies they are performed.
Once established, a careful eye will keep the floors looking great all the time. This is a lot better than the slow demise of floors that are not serviced frequently enough. Although each environment and building will have different service frequencies, they should all include the following.
Keep in mind that the detailing is just as important in this phase of the operation. If you perform the easier jobs more frequently, then the more labor-intensive jobs can be done less frequently with longer intervals in between.
Mix all-purpose cleaning chemical and warm to hot water in accordance with manufacturers recommended dilution ratios (adjust mixture proportionately to how much cleaning is required). Apply a liberal amount of solution to floor. Allow solution to dwell a few minutes (5-15 minutes to allow chemicals time to break down soil and soften floor finish). Affix scrubbing pads (generally blue or green, in case of heavy build-up, use brown or black) to 175-RPM rotary floor machine or automatic scrubbing machine.
Scrub the area using 175-RPM rotary floor machine or automatic scrubbing machine. Detail edges and corners using edging tool and appropriate pads, use 1" razor or putty knives for hard to get areas. Pull solution from edges, corners and hard to get areas to central area using the 12"-14" window squeegee on handle. Pick up solution with wet vacuum. Rinse floor with neutralizer/conditioner or fresh water. Apply 2 to 4 coats of floor finish to desired gloss level. Burnish if desired. Dust mop after burnishing to remove dirt dust and debris caused by burnishing machine.
Even if you are not on a preventative maintenance system and possibly are reacting to a situation, you may find that aggressive scrubbing may be used instead of stripping. Be very careful though. When you are taking over a new account, it’s always best to strip the floor to get it into the condition you want. But, if cost is what your prospective customer wants, then you may be able to offer a more cost-effective method that meets their budget. Either way the aggressive scrub may just be the answer you are looking for.
