By thoroughly sweeping open spaces, the amount of dirt
carried into the
building can be substantially reduced.
For mechanical maintenance cleaning, a scrubber dryer that uses the
one-step method is needed.
crumbles through the residue. Subsequently, the floor must dry
As a natural product, linoleum should be allowed to dry for at least
twelve hours –24 if possible – because any residual moisture could
cause the new coating to detach from the surface (crumbling).
The use of an air blower with adequate ventilation is helpful. This
halves the drying time.
Apply new coating
Then it’s time to apply the new coating. The selected coating agent
must be right for the surface. It must be shaken well before use
and then applied as undiluted puddles on the clean, dry surface.
Subsequently, it must be carefully and evenly distributed with an
applicator or flat wide mop. It is ideal to apply the product at right
angles to the direction of the light, and to mop in the lengthwise
direction. This ensures uniform application. Depending on the
absorbency of the substrate and the stress it is subject to, a second
coating may be advisable.
It should be noted that older flooring absorbs the first coat to
a great degree. The first coat can be carefully walked on after
one hour in order to apply the second coating.
The surface can be walked on in two to three hours. It is not
completely dry and fully able to bear weight, however, until
after 24 hours.
Manual and mechanical maintenance cleaning
Maintenance cleaning is done manually as well as mechanically
with a mop maintenance agent; depending on the amount of
dirt, the solution must be circa 0.5 to 3 percent. For mechanical
cleaning, which allows much more surface area to
be cleaned, the one-step method with a suitable scrubber dryer is
required. The solution is applied to the surface, brushed in and
then vacuumed up in only one process. The surface is immediately
dry and can be walked on.
Preventive cleaning is becoming a greater priority. This component
begins outdoors. Thoroughly sweeping or washing open spaces
substantially reduces the amount of dirt carried into the building.
In addition to the sidewalk and parts of the road directly in front of
the foyer, parking areas, playgrounds and recreational areas must
also be considered. They are the source of a great deal of dirt that
is carried into corridors, stairwells and classrooms.
The concept of preventive cleaning pays for itself very quickly
because keeping exterior areas clean – compared to cleaning
rooms – takes less time and is less labor-intensive, especially
because sweepers and sometimes high-pressure cleaners can
The size of the sweeper and thus the efficiency of the cleaning
depends greatly on the scope of the areas to be cleaned:
33For smaller areas of up to 300 square meters, handheld
with a capacity for up to 30 liters of dirt are used.
33For medium-sized surfaces of up to 1,000 square meters,
hand-held vacuum sweepers with gasoline or diesel engines
(or battery-powered) are used, which among other things
have a suction system with filter.
