  • Ensure you have stirred thoroughly allowing all settled pigments to disperse. A minimum of five minutes stirring is recommended.

  • Surfaces should be clean, free from dust, grease, loose materials and must be dry.


  • Remove dirt and excess dust from the surface area by wiping with a clean rag. If necessary, clean the splice area thoroughly with Weathered Membrane Cleaner. This is necessary on membrane that has been exposed for a few weeks.

  • Thoroughly stir primer until all settled materials are blended into the solution.

  • Application of EPDM Primer: Apply the primer to the membrane with a scrubber pad or paint brush. The coated area will be free of globs or puddles. Note: The use of excessive amounts of EPDM Primer will not significantly enhance the adhesion of the pressure-sensitive product to the EPDM membrane. Use only the amount necessary to obtain 100% coverage of the area where the tape or adhesive will be applied.

  • We have a wide of installation videos available in our training centre. You can find out how to apply the EPDM Membrane, Adhesives, Flashings & Seam Tapes and even a drain outlet if needed.

  • Allow the EPDM Primer to dry until it does not transfer to a dry finger touch. Installation of the pressure-sensitive product as soon as the primer flashes off minimises potential dust contamination and promotes adhesion in colder weather.
