PRODUCT
A factory blended ready to use
cementitious system with special fillers.
STANDARD
Conforming to BS 812 : PART - 3 1975 & SS 26 :
1970.
USAGE & PACKING
5 Kg of FAIRTOP STD per square
meter.
25 Kg Lined HDPE Bags.
DESCRIPTION
FAIRTOP STD is supplied as a
ready to use factory controlled, dry shake
cementitious system blended with special
aggregates, selected for high abrasion and wear
resistance and additives. FAIRTOP STD is used to
obtain a dense, tough, abrasion resistant
industrial floor with non dusty and nonslip
characteristics. Where an extremely heavy floor
is required, we recommend 12 mm thick FAIRTOP HD
ready to use monolithic floor hardener. A
separate data sheet is available on this
product.
PROPERTIES
ABRASION RESISTANCE : FAIRTOP STD
has been tested with FUNDITOR ABRASION MACHINE
using Silicon Carbide Wheels. The sample was
tested for 10,000 revs at a fixed speed and the
amount of wear assessed by measuring the depth
of the groove by abrasion wheels at four points
around the perimeter. The results show that
FAIRTOP STD improves the abrasion resistance
compared to grano by over 150%. COMPRESSIVE
STRENGTH : The FAIRTOP STD cubes when tested for
compressive strength have typical strength of
over 600 kg/cm2 at 28 days. Mho's
scale hardness of FAIRTOP STD aggregates between
7 to 8 scale. COLOUR RANGE : Presently available
in Natural Grey.
WHERE TO USE
Loading bays, Factories,
Warehouse, Car Park, Trucking Lanes, Workshops,
Garages, Subways, Power Stations & Abattoirs.
Recommendation: Refurbishment over terrazzo,
Quarry or ceramic tiles.
INSTRUCTION FOR
APPLYING FAIRTOP STD
(1.1) BASE CONCRETE : The base
concrete should have a minimum cement content of
300 kg/m3 with a slump of 40-60 mm with a low
water cement ratio. To improve the quality of
concrete mixes and enable low w/c ratio to be
kept, FAIRCRETE N normal plasticiser may be used
at a dosage rate of 150-200 ml/50 kg cement.
(1.2) METHOD OF LAYING BASE CONCRETE : The base
concrete must be laid in accordance with good
concrete practice either in bays or long strips.
Particular care must be taken at the corners and
edges of the bays to obtain good compaction and
to maintain level for subsequent troweling
operations. If too much of free water is seen on
the surface, subsequent water content in
concrete must be reduced to obviate the presence
of free water.
APPLICATION
OF FAIRTOP STD
The time of application is very important
in order to derive full benefits of FAIRTOP STD.
If FAIRTOP STD is applied too early, it will
absorb water and may sink to the bottom. If
application of FAIRTOP STD is delayed, no
moisture from the concrete surface will be
available to hydrate FAIRTOP STD, resulting in
poor pitted surface. As a guide, the application
should be made between 1 hour- 2 hours, i.e.
when the surface water on concrete has
completely evaporated. (When tested with Thumb,
it leaves an impression but concrete does not
stick to the Thumb). The application rate is 5
kg/m2 of FAIRTOP STD powder. (1) The application
is made in two stages. First 50% of the required
material is broadcast evenly manually and when
the surface darkens with the absorption of
water, the surface is floated. The second
application is made immediately after, by evenly
broadcasting the balance 50% material and when
the surface has darkened with the absorption of
water the surface is floated. Power floating
would be ideal. Two floorings are recommended
with half or full disc. The second troweling is
done after the surface has sufficiently stiffed,
i.e. after two hours of the first troweling to
close any pores and remove any undulations on
the surface. Final hand troweling is recommended
to remove any disk marks. CURING : After final
troweling, as soon as the surface has hardened
sufficiently to prevent damage, it should be
covered with and polythene sheet and made air
tight by placing sand around the sheet for a
minimum period of 7 days. Alternatively, curing
by water podding or coating of FAIRCURE C is
recommended.
SURFACE
SEALING & STORAGE
If surface sealing is thought to be necessary,
two coats of FLOORSEAL C epoxy clear floor
sealer may be applied for added protection
against penetration of oils, grease, water and
mild chemicals. Or alternatively, two coats of
SAFECORE EP epoxy floor coating can be applied
to provide further protection to concrete and
steel surface apart from aesthetic appearance. A
separate data sheet is available on the above
products. JOINTS : All expansion joints must be
filled with FAIRSEAL - Polysulphide sealant. The
saw cut construction joint may be filled with
FLOORSEAL PS flexible epoxy resin. (a separate
data sheet is available on this product) STORAGE
: 6 months period in dry, shed condition in
original sealed packs.
