Floor Cleaning in Hospitals

The floor must then be left to dry. Linoleum, a natural product, should be left to dry for several hours or overnight. Good ventilation must be ensured.

The new coating can subsequently be applied. This protects the floor covering against damage, greatly facilitates maintenance cleaning and provides a shine that looks clean and hygienic. This also impedes bacteria and virus attack.

Synthetic elastic floor coverings, e.g. PVC – can be treated with all standard coatings, whereby highly elastic linoleum can only be treated with materials containing wax.

The coating material must be shaken well before use and subsequently applied to the clean and dry floor covering in “puddles”.

The coating material must subsequently be carefully distributed evenly with a lambs’ wool mop. Depending on the surface and traffic, it is recommended to repeat the coating two to three times. In addition, older floor coverings absorb the coating material to a greater extent.

The first coating dries after about 30 minutes and can be walked on carefully. The next coating can subsequently be applied. However, the coating takes about 24 hours to fully harden.

In particular areas where disinfectants are used, it is recommended to apply a ceramic sealant for added resistance.

Maintenance cleaning using two methods

The following applies to maintenance cleaning: never wet wipe coated floors. For manual cleaning, it is recommended to use the one-step method for wet wiping small areas.

For mechanical maintenance cleaning, which allows much larger areas to be cleaned, a scrubber drier should be used with the one-step method: this machine applies the cleaning agent, brushes the floor and picks up the dirty water in a single pass. The floor covering is immediately dry. Cleaning with a machine is economical from an area of 200m². The cleaning result is also more efficient and hygienic.

Quickly remove minor “damage” by rejuvenating or polishing

Light scratches or heel marks can easily be removed with a spray cleaner. The cleaning agent is sprayed on to the marks and then polished either with a high-speed machine, polisher or roller scrubbing machine with white, soft brushes or yellow pad rollers.

Choosing the right machine

Different demands are placed on the cleaning and care of PVC and linoleum due to the materials used for their production. Scrubber driers with roller scrubber head are particularly suited to these tasks as they are ideal for deep and maintenance cleaning as well as polishing. Only suitable pads must be used. The speed can be adjusted from 300 to 1000rpm. The contact pressure and water volume can also be adjusted as required:

  • for deep cleaning – maximum contact pressure and speed as well as hard green roller pads
  • for maintenance cleaning – minimum speed and contact pressure as well as soft white roller pads
  • for polishing – maximum contact pressure and speed as well as soft yellow pads

Final work

In order to prevent the transfer of microorganisms, which thrive in moist and warm environments, the following measures are essential after cleaning:

  • Emptying and cleaning tanks, which must remain open to dry
  • Cleaning and rinsing brushes, brush head, suction hoses and suction bar
  • Wiping exterior machine surfaces

Numerous factors must be taken into account during the planning phase with regard to the selection and subsequent cleaning and care of floor coverings in hospitals: • In areas where patients are treated, floors should be unstructured, washable and…
