Looking for an easy solution to flash difficult angles and penetrations? Announcing JM Single Ply Liquid Flashing—our new cold applied, polyurethane-based product that combines the ease of a liquid application with the strength of a reinforcing scrim. The result is a uniform, self-terminating flashing ideal for tying together most common roofing materials with all JM single ply membranes, even EPDM. This liquid-based product allows for the flexibility you need to create attractive, functional flashings and address odd-shaped penetrations. The pre-portioned packs are for operator ease of use, and they ensure optimum mixing ratio every time.

  • Works on all JM single ply membranes (TPO, PVC, EPDM)
  • Highly reflective UV-resistant white color
  • Mostly odorless, LVOC and solvent-free
