Generously dimensioned dirt-retention areas result in an effective reduction of dirt being carried in.
Surface disinfectants, e.g. based on quaternary ammonium compounds (QAV), leave behind residues that can lead to stickiness and increased soiling of floor covering surfaces. If necessary, these residues should be removed using suitable cleaning agents. (See also the information of the German Industrial Association for Hygiene and the Protection of Surfaces in Industrial and Institutional Applications (IHO: Industrieverband Hygiene und Oberflächenschutz für industrielle und institutionelle Anwendung e.V.)
All materials and methods used must be agreed with the cleaning, polishing and disinfecting agent manufacturers. Drugs, wound and hand disinfectants etc. should be removed immediately if possible. Otherwise, these media dry on the surface and, irrespective of the type of floor covering, lead to stains that can often only be removed using targeted stain treatment (see stain table).
Spilled colourless infusion solutions containing the active substance of dopamine lead to brown stains due to reactions with cleaning, polishing or disinfecting agents, regardless of the type of floor. Stains can only be prevented by immediately mopping up the medicine, which is initially colourless. Recent stains of up to 3 days old can be removed by simply wiping them off with conventional phosphoric acid-based sanitary cleaners. In the case of stubborn and old stains, using certain oxygen-splitting surface disinfectants, such as “Dismozon pur” (Bode Chemie, Hamburg), “Apesin AP 100” (Tana-Chemie, Mainz), have proven to be the most effective means of stain removal. These VAH-listed products are sprinkled on and moistened with water. The exposure time is at least 10 to 15 minutes. Then mop up the loose dirt without leaving any residue and wipe off thoroughly with water
It is important to work a suitable and highly concentrated wash polish into the floor covering after intensive stain removal as per the manufacturer’s recommendation. The applied wax polish film should then be compacted by polishing (e.g. using white pads).
noraplan® signa ed, noraplan® sentica ed, norament® 928 grano ed, noraplan® astro ec
We strongly advise not to use routine cleaners, wax emulsions or self-shine dispersions; as such products may not only lead to a cleanroom contamination but also exert a negative impact on the flooring’s electrostatic properties.
Please refer to the initial cleaning procedure for intermediate cleaning.
In the case of double floors, the plate elements are only butt jointed against each other and are not absolutely leakproof. Normal wet cleaning procedures must therefore not be used! Ventilation plates: Special care must be taken with these plates during cleaning.
Remove loosely adhering dirt by using suitable, dry procedures.
Cleaning with the spray method and using a red pad.
Special spray cleaners or cleaning agents suitable for spray cleaning must be used. The proper method of application is shown in the manufacturer’s product descriptions. The conductive properties of our nora floor coverings must not be adversely affected by the polishing agents, and suitability may have to be agreed with the respective wash polish manufacturer.
Damp-wiping with damp or prepared cleaning agent fabrics (gauze cloths). If wiping products are used, they can be dry polished at regular intervals with a polishing machine (white pad).
Thorough intermediate cleaning should be carried out as required after longer periods of time. The procedure is the same as for initial cleaning.
Before starting work, sufficient self-tests must be carried out in order to ensure that the cleaning measures, materials and machines meet the special requirements for sports halls. Hard coatings must not be used on nora rubber floor coverings! The products and procedures used must not adversely affect the floor covering and the slide friction coefficient (tested according to DIN 18 032, part 2).
Initial polishing treatment as per the recommendation for the respective floor covering
Only products suitable for sports halls may be used. You must obtain approval from the wash polish manufacturer.
Routine cleaning should be carried out as per the applicable cleaning recommendations. The chemicals used must meet the requirements for sports hall floors.
Steptreads are cleaned in the same way as the procedure provided in the standard cleaning recommendations.
See floor coverings.
The cleaning and care products are recommendations of the cleaning product manufacturers on the German market.
