Colstrips are easy to apply to bituminous and concrete surfaces. Before application always ensure the area is clean, dry and free from dust and oily residues. Concrete surfaces should be primed with CP Primer ensuring that the primer is completely dry before the Colstrips are applied.


Preheat the surface making sure it is free from moisture, remove Colstrips from their protective wrapping and place on the road surface.

Heat the Colstrips with a propane torch using a slow sweeping motion, making sure that you do not spot heat any areas as this may scorch the material.

Colstrips must be heated until it starts to bubble and melt when heat can be removed.

The material will cool and harden within 5-10 minutes of installation.

Do not use Colstrips in wet conditions.

Applying insufficient heat will result in inadequate bonding and subsequent failure of the material.
