Nitofloor Hardtop STD

Non metallic, monolithic surface hardening
compound
Uses
Nitofl or Hardtop Standard provide a highly abrasion resistant
surface to concrete fl oors by the dry shake-on method which
ensures that the hardwearing surface bonds monolithically
to the base concrete. They are ideally suited for all industrial
areas subject to the heaviest traffi c, e.g. loading bays, trucking
lanes, car parks, workshops, machine shops, ramps and
spillways.
Advantages
  Non metallic - does not rust or stain.
  Provides a hard, abrasion resistant surface
  Forms monolithic bond with base concrete
  Easy and economical to apply
Description
Nitofl or Hardtop Standard is quality controlled, factory blended
powder which are ready to use on site. They contain special
hardwearing aggregates which have been selected for
abrasion and wear resistant properties as well as shape and
size. These latter considerations, together with the use of
high performance workability admixtures, produces a material
which is easy to trowel into the surface of fresh, wet concrete.
Nitofl or Hardtop Standard cure monolithically to provide a
dense, non-porous surface which is extremely hardwearing
and abrasion resistant. Monolithic cure ensures that problems
normally associated with thin ‘granolithic’ screeds, viz., shrinkage,
cracking, etc., are completely overcome.
Being non-metallic, Nitofl or Hardtop Standard provide a nonslip
surface which will never rust and disintegrate.

Properties
Abrasion resistance (IS : 1237-1980)
Nitofl or Hardtop Standard has been tested as per IS:1237 -
1980 against control concrete for abrasion resistance.
Test results showed that Nitofl or Hardtop improves the abrasion
resistance of concrete by 225% and Nitofl or Hardtop
Standard by 150% when tested as per guidelines in IS:1237
- 1980.
Nitofl or Hardtop Standard are applied in two stages.
(a) The fi rst application is made using 50% to 70% of the total
material. Nitofl or Hardtop Standard is evenly broadcast onto
the concrete surface. When the material becomes uniformly
dark by the absorption of moisture from the concrete this fi rst
application can be fl oated. Wooden fl oats or, on large areas, the
power trowel with disc may be used. It is important, however,
that the surface is not over worked.
(b) Immediately after fl oating, the remaining Nitofl or Hardtop
Standard is sprinkled evenly over the surface. Again moisture
is absorbed and the surface can be fl oated in the same way
as before.
Final fi nishing of the fl oor using a power trowel can be carried
out when the fl oor has stiffened suffi ciently so that damage
will not be caused.
