A-Grip HFS

£108.00

Size: Three-part 20Kg Kit

Coverage: Typically, 8-9m²/20Kg Kit (dependent on aggregate/substrate)

A-Grip HFS is a liquid polyurea adhesive, specifically formulated for High Friction Surfacing applications.

A-Grip HFS is supplied as a three-part kit. A-Grip HFS has excellent adhesion properties on bituminous, cementitious, metal and non-oily wooden surfaces, and most aggregates. We would recommend using calcined bauxite and granite aggregates.

When applied at 1.3mm and using 6Kg/m² of Chinese bauxite, A-Grip HFS passes the Transport Research Laboratory scuffing test for Type 1 surfacing (an erosion index of zero and texture index of 1.4 is achieved). A-Grip HFS does not need a primer and will bond to damp or uncured concrete (over 4 days old).

Description

 

A-Grip HFS is a high performance, cold-applied, all liquid, polyurea system specially formulated for high friction surfacing applications. Unlike many traditional systems. A-Grip HFS has an award winning low carbon footprint and a proven service life of over 10 years. A-Grip HFS requires no primer and whe cured, has excellent adhesion to bituminous and cementitious road surfaces.

Unlike rosin ester (hot-melt), epoxy and MMA (Methyl methacrylate) systems, A-Grip HFS incorporates the latest developments in polyurea technology to provide a high performance, cost effective, safe alternative with award winning green credentials. Whilst commonly used systems can deteriorate after just a few months, A-Grip HFS has a proven lifespan of over 10 years.

 

Installation

Uretech HFS is mixed using a drill and paddle in 20kg
‘kits’ then spread using a fabric roller or serrated
squeegee. Stir the ‘A’ component for one minute to
disperse any settlement, then add the other two
components and continue to stir until mixed. Full mixing
should take no more than an additional 60 seconds with
the correct equipment. The mixed material remains in
a mobile, liquid form for approximately 5-10 minutes,
after which a light gel is formed (lasting approximately
15 minutes). The material then sets into a soft solid.
Excess material can be removed whilst in the gel form.

 

The material is fit for traffic after approximately 2
hours but will increase in properties over a period of
a few days. Aggregate should be broadcast onto the
material in its liquid state. It is vitally important that this
is carried out as soon as possible after spreading and
certainly within 5 minutes. Aggregate will not adhere
properly to semi-cured or cured adhesive. For Type 1
approved high friction surfaces, calcined bauxite
(1-3mm) should be used. The adhesive should be
applied at a rate of 1.33mm depth (1.9 kg/m2) i.e. a
20kg kit should cover 8-10m2 on a good surface.

 

At this rate the binder
should retain 6kg/m2 of
3mm aggregate. Do not try
to spread the material to
more than 10m2 per kit.
Optimum wear characteristics
are achieved when the
aggregate particles are
half-buried into the adhesive
and this will not occur if
there is not enough depth of
adhesive.
