PRODUCT DELIVERY:
Upon delivery and prior to
being laid, all items should be
examined for damage and wet
bags of aggregate. Find the site
sheet which contains the mix
design, separate any anti slip
grit and, if using UV resin, find
the catalyst. Syringes should be
found on Pallet 1 of your delivery.
The use of natural aggregates
especially on larger projects,
result in variations of grades
and shades. To limit unwanted
variations in finishes please
ensure that the following is
carried out: check that all
aggregates supplied have the
same batch number or if multiple
batch numbers have been
supplied the quantity received
results in consistent blending
in each mix. If a mix requires
2 bags of the same aggregate,
take a bag from one pallet
and the second from another.
Ensuring you follow the mix
sheets provided with the order
stringently.
PREPARATION OF
SURFACE:
Concrete surfaces to be treated
should be clean, dry and free of
laitance, oil, grease and loose
friable particles which could
affect adhesion.
Asphalt surfaces must be clean
and dry, details of suggested
suitable base build ups are
available on request. A suitable
edging detail should be specified
using either brick, stone,
concrete, aluminium, timber or
steel as required to provide a
high quality finish detail.
If the area is large install purpose
day joints/breaks. Discuss with
the client how to visually break
the area up to look aesthetically
pleasing.

Mark your area into sections
according to the expected
coverage rate. This can be
found on the site sheet. Double
check you have enough material
to complete the area.
APPLICATION
CONDITIONS:
For best results, certain
atmospheric conditions must
be met. Humidity must be less
than 80% and atmospheric
temperature must be above 5˚C.
For a UV system, it must be no
more than 30˚C, for a Non-UV
system no more than 25˚C.
The surface temperature must
be 3˚C above the dew point.
Use a hygrometer and surface
thermometer to obtain these
values. Check weather forecasts
for rain.
STORAGE
CONDITIONS:
Store all goods above 7˚C, not in
direct sunlight, wind nor rain.
All resin comes with a 6 month
shelf life.
MIXING AND
APPLICATION:
The resin Part ’A’ & ‘B’ is
delivered in pre-weighed units.
For UV resin systems, Part 'A'
has been pre-catalysed. To
further catalyst Part ‘C’ can be
added (refer to the catalyst
guidance table found on site
sheet provided with each order).
For Non-UV resin systems do
not add any catalyst. Be aware
during hot conditions the resin
will cure quickly.
Add aggregates into a suitable
forced action mechanical mixer,
larger stones first, smallest stones
last. Do not add the sand/glass
at this stage. Whilst the stone is
being loaded into the mixer, mix
your resin using a slow speed, high
torque drill with mixing paddle for a
minimum of 45 seconds.
Add the mixed resin immediately
into the pre-mixed aggregate and
then add the sand/glass.
Mix for 1-2 minutes, mix times
should be consistent for all mixes.
Discharge into a suitable plastic
lined 90 litre wheelbarrow.
Take the material to the point of
application and spread evenly
across the surface at ~ 2mm above
the required depth using a straight
bladed lute/spazzle or screed
sledge.
The surface should then be hand
trowelled. Optionally use a lightly
weighted finishing power trowel.
Compact the resin bound surface
to a smooth finish, then apply
glass grit or aluminium oxide scatter.
SLIP RESISTANCE:
To improve the slip resistance
on the surface, fine glass grit
should be applied at a rate of 50g
per sqm. This can be provided
with your order. This is to give
initial anti-slip properties while
the resin coats the top of the
surface. Over time the top layer
of resin will wear away, leaving the
residual aggregates. These have
a PSV>50, providing a lifetime of
anti-slip.
CLEANING OF
EQUIPMENT & SKIN:
Tools, brushes etc should be
cleaned immediately after with a
solvent cleaner. For cleaning of
hands/skin, use a deep cleaning
soap with water. If a rash appears
seek medical attention. Keep the
solvent away from the job to avoid
spillages.
