The Windsor PDIR Method provides a simple, easy-to-follow path for understanding how floors become dirty and how to address them.
PDIR stands for Preventative, Daily, Interim and Restorative, and if these four areas are addressed in a facility a successful floorcare program can be implemented.
Windsor has made this method the cornerstone of their education program for the past seven years.
What they have learned is when people who are involved with a facility understand that soils which are brought into their building drive all the floorcare processes, they can then address their issues with the PDIR Method.
Dry soils brought in with foot traffic scratch and abrade carpet and hard surfaces with the equivalency of 120 grit sandpaper.
It is this dry soil that damages carpet to create traffic lanes and dulls stone and finished floors.
Therefore the first step in the PDIR Method is to stop this soil from entering the building in the first place.
Industry studies attributed to the ISSA say 1,000 people in 20 days can track in 24 pounds of soil.
A separate study says it can cost $700 per pound to locate, identify, contain, remove and properly dispose of soil once it is inside the facility.
With costs like that, it is much less expensive to stop soils using a two mat system and a sweeping program; the components involved in the Preventative step of the PDIR Method.
Soil that enters the facility should be removed on a daily basis to reduce the damage it causes to the substrates.
With Daily Maintenance these soils are removed through vacuuming on carpet or vacuuming, sweeping or dust-mopping hard surfaces.
Interim Maintenance is the process of maintaining a clean, consistent appearance of the floors with less water, chemical, labor and downtime versus Restorative Methods.
Interim methods allow a facility to avoid spikes in appearance where the floors become heavily soiled before being cleaned with time, labor and water intensive Restorative Methods.
Examples of Interim Methods are encapsulation cleaning on carpets and top scrubbing a recoating on finished floors.
Restorative methods are the final step in PDIR.
These methods are the most time, labor, chemical and water intense, but their goal is to restore the substrates as close as possible to a “like new” appearance and create a healthy indoor environment.
Examples of Restorative Methods are water extraction on carpet, stripping and finishing on finished surfaces and diamond grinding on marble.
