  • Pre-packaged units ready for use

Directions for Use

Surface Preparation

  • New concrete surfaces shall be a minimum of 7 days old. Old oil-contaminated concrete surfaces shall be washed with detergent and water and allowed to dry.
  • Suitable mechanical treatment such as vacuum grit blasting or mechanical scabbling are recommended to ensure the removal of contaminants.
  • With severely contaminated surfaces, where the evidence of oil patches still remains, a coat of CPR 904 – Low Viscosity Concrete Sealer shall be Applied at a rate of 5m²/litre and allowed to dry for a minimum of 4 hours prior to the application of CPR 405 – Concrete Primer – Oil Tolerant – Epoxy HB.


  • CPR 405 – Concrete Primer – Oil Tolerant – Epoxy HB is supplied in pre-weighed containers ready for mixing.
  • Pour the contents of the CURING AGENT tin into the BASE container and thoroughly mix, preferably by mechanical means until a uniform colour is achieved.


  • Apply by brush, roller or squeegee to the prepared surface at a nominal rate of 0.3 to 0.5Kg/m².
  • Ensure that the surface is thoroughly wetted out.
  • If the primer is to be allowed to cure prior to overcoating, then it is permissible to broadcast fine dry Quartz into the wet primer to assist subsequent adhesion of  CPR Epoxy Coatings. CPR  Epoxy Screeds and Mortars may be applied to the wet primer.
  • Where application conditions also involve a damp substrate, then 2 coats of CPR 405 – Concrete Primer – Oil Tolerant – Epoxy HB shall be applied, broadcasting into the second coat only.
