If you have an alpha roof system or if there was any coating applied such as an acrylic or elastomeric etc..you will first need to apply the ProFlex Primer.  The primer acts as a barrier so that any non compatible aftermarket products do not come into contact with the roof.

If you have a Fleetwood model or if someone put a 3rd party coating over your roof you would definitely need the primer.  Also if the black is starting to show on your epdm roof then you would also need the primer in that situation

Thank you

please see below

thank you

 

EPDM is used in a wide range of recoating and repairs, these include:

  • Weathered metal roofing
  • Weathered sheet rubber roofing
  • Weathered modified asphalt ProFlex primer required and urethane foam roofing
  • Steel (especially if exposed to salt environment)
  • For Fleetwood models with ALPHA roofs or an Alpha Rubber roof you will need to use the ProFlex Primer. You will be able to refer to your manual to determine if you have a roof made by Alpha systems
  • Although Liquid Roof may be used in conjunction with the ProFlex primer directly on wood it is not warrantied
  • In the event anyone has put a 3rd party coating over the original epdm roof you would need to prime with the ProFlex primer.

here are the conditions for the primer

 

The following roof types-substrates do NOT require the ProFlex primer only one coat of the Liquid EPDM

  • Various Metal Roofing systems
    • Weathered Galvanized

    • Weathered Copper
  • Any original epdm rubber roofing system
  • Sprayed Urethane Foam
  • Fiberglass
  • PVC
  • Acrylic Sheet and any acrylic based products

  • Built up asphalt roofs-You would first need to apply our ProFlex primer before applying the liquid EPDM.

  • Modified asphalt roll roofing - First needing our ProFlex primer

  • Neither the primer or Liquid EPDM can be applied to glass
  • Silicone caulk-Any silicone caulk needs to be removed and replaced with either butyl or acrylic caulk
  • Heavily trafficked surfaces like decks or porches
  • Hypalon Membrane
  • Wood applications that are first primed with our ProFlex primer
  • Concrete where there is little foot traffic (concrete applications require one coat of the ProFlex Primer)
