Stud Grout has been developed in order to solve the pouring and setting problems encountered with some bitumen grouting materials. Adhesion, flow and pouring properties have been improved whilst still retaining recommended softening point and penetration characteristics.

Where to use?

  • To secure all types of reflective road studs


When grouting road studs, use the road stud manufacturer’s installation instructions ensuring that studs are dry and clean.


When using Stud Grout to secure road studs,  the wall of the cavity should be primed with CP Primer to ensure a good adhesion of the grout. Care must be taken to ensure that there is no condensation on the studs and in extreme cold, these should be taken from a warm storage area or warmed prior to laying. In cold conditions, the temperature of the Stud Grout should be raised accordingly and in frosty weather, this could well be up to, but not above 190°C to counteract the chilling effect that the cavity walls and body of the stud will have on the poured grout.


Spread Rate – refer to road stud manufacturer’s guidance.
