EPDM

Basics

• A Thermoset Elastomer
• Used Mainly in Roofing/House Membranes, and Rubber Surfacing (no good term for this, but essentially the bound granule surface at playgrounds / "splash parks", can also use Granulated Tires / Thermoplastic Vulcanizates ( TPV ))

Patching

• See video at [1] minute 16:50
  • Apply primer, let dry
  • Take backing off patch
  • Press on, with roller

EPDM Installation Directly Over Insulation

• Yes, it can be done.
• Insulation is glued down to prevent thermal bridging, as opposed to mechanical fasteners
• EPDM is glued to insulation using contact adhesive (solvent), as opposed to latex water-basedglue

• Note that OSB is glued down. Is there mechanical fastening as well?
