Cleaning Resilient
Floors
Floor Types - Pure Vinyl,
Thermoplastic and Linoleum
Common areas of use :- Hospitals, Schools, Offices, Retail
Stores
Most new floors in this group are pure
vinyl, either sheet or tiles, the main reason being that vinyl is more
resistant to chemical attack, is hard wearing and quieter under foot.
Vinyl Asbestos and Thermoplastic floors can still be found and can be
recognised by the size of the tile 9" (Pure vinyl 12"), and
their hardness under foot. Thermoplastic tiles are made from Asphalt
and Asbestos, are very brittle and have poor resistance to chemical
attack. Vinyl Asbestos tiles are more resistant to chemicals but are
also brittle and mark more easily than Pure Vinyl. Linoleum Is made
entirely from natural products i.e. cork, sawdust, and oils with a
jute backing, is quiet under foot and hard wearing. As it is made from
natural products it can be treated with wax polishes, providing that
care is taken when stripping (see note 1),
although it is preferable to use water based products.
Cleaning Technique
PREPARATION: Before starting ensure that you have
adequately isolated the area to be cleaned so as to protect the safety
of the public and other members of staff. You should ensure that all
reasonable safety precautions have been taken, for more information
contact the Health and Safety Executive.
Stripping The Floor
First remove all dirt, old seal and polish. To do this use a
standard speed rotary floor machine fitted with a solution tank, drive
disk and a black pad or preferably green on Linoleum .
Fill the tank with Nova Starbrite
Stripper at a 1:8 dilution ratio and scrub the floor releasing
solution as you go. Allow the chemical to soak for 5 minutes, then
scrub again only releasing solution if necessary, (This operation may
have to be repeated 2 or 3 times if there is a heavy build up of old
polish).
Note:
Extreme care must be taken when stripping a linoleum floor as high
alkali stripping agents are harmful to linoleum, Use a dilution ratio
of 1:12 and rinse thoroughly.
Next dry the floor or, if working on a
large area, use a wet pick up machine fitted with a fixed squeegee or
use the standard head if in a small or confined area. Inspect the
floor to check that all old polish and dirt has been removed if not
repeat the above procedure.
The floor must now be neutralised as
most strippers are high in alkali and will have left the floor with a
high pH value causing any seal or polish to dust. Fill a bucket with
plain water and add a small amount of Prorinse (or vinegar if not
available) and mop liberally onto the floor and allow floor to dry. If
time allows, dry burnish the floor with a machine fitted with a red
pad.
Sealing The Floor
Sweep or vacuum the floor to remove all dust. Put a quantity of'
Novacryl water based seal into a clean bucket, first coat 1 litre = 30
sq m, second coat 1 litre = 60 sq m, fit a clean applicator sponge
into a mop wringer and dip into the Novacryl, wring out sponge, apply
seal to the floor taking care to give an even coverage. If dry streaks
appear too little has been applied; if air bubbles appear too much has
been applied. If this happens wring out sponge and smooth out the
effected area.
After 30 minutes apply second coat of
Novacryl at right angles to the first, allow to dry, and open windows
to improve ventilation, the floor should take 15 - 20 minutes to dry
in normal conditional if it dries in under 10 minutes the floor is
still porous, apply another coat.
Dressing The Floor
Using a clean bucket and applicator apply two coats of Saturn
Steel floor polish (1 litre = 60 sq m), following the same procedure
as for Novacryl , allowing at least 30 minutes for drying before
walking on the floor. The second coat of Saturn Steel should be
applied leaving a 6 inch gap from the skirting. This avoids a build up
of polish around the floor edge.
Maintaining The Floor
The maintenance programme can be started 24 hours after laying the
seal and polish.
When deciding on a maintenance
programme consideration should be given to the amount of foot traffic
over the floor, also the amount and type of dirt likely to be
deposited. This will vary considerably depending on the type of
building, i.e. a DIY Store with bags of cement and sand stored, should
be regarded as a heavy traffic area with the need to repair the finish
on a regular basis. A hospital ward with minimal foot traffic and
light soiling should be regarded as a light traffic area. Account
should also be taken of the distance of the area to be cleaned from
the outside entrance to the building, i.e. the further from the
entrance the lighter the cleaning programme.
In light traffic areas a daily sweep
with a dust control mop or vacuuming combined with a once a week
"spray clean" will keep the floor in good condition.
Spillage's should of course be damp mopped.
In medium or heavy traffic areas
increase the frequency of "spray cleaning" up to once a day
in very heavy conditions.
Spray cleaning not only cleans and
shines the floor but also increases the ability of the polish to
withstand scuffing and prolong the time between, stripping and
resealing, in some cases dispensing with it altogether.
Spray cleaning should be carried out
with a high speed floor machine fitted with a red pad. A spray bottle
filled with a solution of Janitorial Express Floor Maintainer diluted
1-8 with water should be prepared. Remove dust and litter by sweeping
or vacuuming, then working systematically over the floor, spray a very
fine mist of solution over approximately 2-3 square metres at a time
(if you can see it on the floor you have applied too much!). Pass the
machine over the floor until dampness has disappeared and a high shine
is visible.
Any stubborn marks should be given a
second spray with additional machine passes until removed.
The floor should then be swept or
vacuumed to remove dust and debris not taken up in the pad. Fitting a
vacuum unit to the machine dispenses with this operation thereby
saving considerable time.
Repairing The Finish
As the finish on the floor wears (usually in high traffic areas),
it can be repaired quickly, this avoids the need for complete
stripping and resealing. To do this thoroughly clean the floor. Using
a High speed rotary machine fitted with a blue pad. Spray-clean the
floor with a solution of Janitorial Express Multi Clean Extra, diluted
1:40 with water, then rinse with cold water. When dry, apply a thin
coat of Saturn Steel to the worn area only. Should further coats be
necessary these should be applied at right angles to the previous coat
making sure each coat is dry before applying the next. Leave to dry
for 30 minutes then dry burnish with a red pad to blend in with
re-treated areas.
EQUIPMENT REQUIRED
Machines for scrubbing and stripping floors should be standard
speed (around 180 / 200 rpm). Use a wet vacuum for drying the floor
with a fixed squeegee for large areas or the standard tools for small
areas. Spray cleaning should be carried out by using a high speed
machine, up to 450 rpm. Machines which revolve at speeds in excess of
450 rpm loose their ability to clean and should be used for burnishing
only.
- SCRUBBING/STRIPPING MACHINES -
Standard Speed (180/200rpm)
- BUFFING/SPRAY CLEANING MACHINES -
Fast (400/450rpm)
- WET VACUUMS - Preferably With Fixed
Squeegee
- BRUSHES/PADS
The use of brushes on these types of flooring is limited as pads
generally give a better performance. The pads to use are as
follows:-
| Stripping |
Spray
cleaning |
Restore |
| black |
red |

| green |

Large areas of these types of floors,
i.e. Hospital Corridors, Retail Stores, DIY Stores etc., can be
maintained (once the have been prepared), by using a scrubber dryer
(fitted with soft brushes or pads and using Stride 1000 in the tank)
to wash and dry the floor, followed immediately with a mains or
battery burnishing machine fitted with a "Thermal" pad to
restore-the shine. This method has a high initial cost but saves on
labour costs which is about 80% of the annual cost of a cleaning
programme.
