This primer is needed before using hermoline on very smooth surfaces (eg polished concrete) or surfaces that are prone to dusting (eg concrete or old, weak asphalt). Most Thermoline applications are on ordinary asphalt and do not require the Primer.

Spray the primer over the area to be marked and allow the solvent to evaporate for at least two minutes before applying a Thermoline marking.
