Application of bitumen primer


Application of bitumen primer

bitumen primer is a bitumen based primer for the surface conditioning of concrete and timber substrates prior to the application of heat fused APP and SBS modified bitumen membranes such as UniTorch.


  • Versatile bituminous primer for porous and non-porous surfaces

  • Used on concrete, metal and timber surfaces
  • Economical & easy to apply


Bitumen Primer may be applied by brush or roller. The applied film must be allowed to dry before being overlayed with any waterproofing treatment so as to avoid solvent entrapment.

Surface Preparation

As with all surface coatings, good preparation is of paramount
importance to the success and long-life of the system.

  • Ensure that the surface to be treated is dry and sound, free of
    loose, dusting or flaking particles and free from contaminants
    such as grease and fungus.
  • Defects such as cracks, broken mortar joints, etc. are to be
    repaired prior to primer application.
