Colasgrip is a high performance non toxic high friction and
coloured surfacing. It comprises of a two component thermosetting
pigmented epoxy resin binder dressed with natural or pigmented
coloured aggregates, normally calcined bauxite or granite.
Colasgrip is a chemically curing system and can also be used for
protection against fuel, oil spillage and de-icing salts. It can be
supplied in road and heritage grades.
- quick to install
- excellent skid resistance
- manufactured to BS EN ISO quality and environmental
Colasgrip is ideal for the delineation of bus lanes and cycle
lanes, for pedestrian crossings, junctions, bends, roundabouts and
other hazard areas. For each type of application Colas can
recommend the right type and size of aggregate to use.
Application of Colasgrip by hand
Colasgrip can be applied by spray machine or by hand. For
application by spray machine please refer to the method statement
for spray application.
The equipment required for the hand application of Colasgrip is
generally composed of:
- 1 stirrer (low speed high torque drill fitted with helical
- squeegees (serrated edge "v-notch" and flat bed types 1 truck
- Mobile generator
- Mixing container
And may include optional equipment such as a mechanical sweeper
with suction system and heating tanks.
- Prior to application of Colasgrip, ensure that surfaces are
clean, sound and dry.
- All dust, dirt and loose material should be swept from the
- If the surface is dirty or contaminated by oil or grease,
it should be water jet washed or cleaned using a 2% aqueous
solution of detergent applied over the whole surface. The surface
should then be scrubbed vigorously with a stiff brush to remove
contaminants, thoroughly washed with clean water and allowed to dry
or dried with a hot compressed air lance.
- Any damage to the surface or irregularity must be repaired
properly before applying Colasgrip. New asphalt should be left
for at least 4 weeks trafficking before applying Colasgrip.
Spraygrip should not be applied to "fatted up" black top or multi
layer surface dressings.
- Ensure surface is completely dry and above 5°C.
- If necessary the texture depth of the surface should be studied
and measured to determine the consumption rate of the binder.
Measurement should be carried out using the sand patch method.
- The A and B components (resin and hardener) may separate in the
containers on storage. It is essential that each component is
stirred using the low speed high torque drill fitted with helical
stirrer for 2 minutes and re-dispersed properly before mixing
together. Component A should be stirred first ensuring that the
stirrer is cleaned before stirring Component B.
- If coloured binder is required 1 sachet of pigment should be
added to component B and mixed for 2 minutes until it is a
- Empty the contents of the smaller container (A component) into
the larger container (B component) for mixing and blending (if
pack size will allow). If more convenient both components can be
poured out and mixed in a plastic bucket. Add the A component to
the B component in the bucket for best blending results.
- Mix contents together using the low speed high torque drill
fitted with helical stirrer.
Advised duration of mixing process - two minutes.
It is essential that all of the components from each container are
mixed thoroughly with the other component. Ensure material
from the bottom, sides and corners is mixed properly.
Failure to mix the binder properly will result in poor
strength and cure of the system.
- In cold weather, store the binder overnight in a warm store.
This lowers the viscosity of the binder and makes it easier to
use. It may also be necessary to pre-warm the A and B components to
20ºC to help with pouring and blending. Please consult the Colas
technical department for further advice on this.
- Place the aggregate to one side.
- The temperature of the A & B components should be between
+10°C and +35°C before mixing, with the ambient temperature
range being between +5°C and +35°C.
- The mixed binder should be poured out as uniformly as possible
and distributed by squeegee with serrated edge (V notches) 5mm
wide and 5mm deep at 5mm centres. Care should be taken to obtain an
even coating without puddles or thinly spread areas. .Application
rate will depend on texture depth and will be between
- The aggregate should be applied as soon as possible. Bags of
aggregate are distributed along the length of the area to be
covered. As the epoxy resin is applied the bags are split and the
aggregate applied onto the binder to excess. The aggregate should
be "broadcast" onto the surface and where necessary a flat bed
squeegee can be used to even distribution. Rolling is not required
Using 1-3mm aggregate the application rate is 10-12kg/m2.
- After all of the areas have been covered with aggregate to
excess, the material must be allowed to cure. The time it will
take the material to cure will vary according to the surface
temperature, but is typically 3 hours at 20 ºC .After completion
the area should be swept to remove excess aggregate to leave around
7-8kg/m2 of aggregate on the surface. The excess aggregate may be
collected and used again as long as it has not been
