General Recommendations for Installation

  • Check the substrate for any defects or sharp objects
  • Inspect the EPDM sheet for any damage before installation
  • Membranes must be allowed to relax for a minimum of 30 minutes before installation. In cold weather the membrane relaxation time may increase. 
  • If you need to cut the EPDM for any reason, make a straight neat cut using scissors, markers and chalk lines.
