- Membrane Preparation:
- Substrates must be clean, dry and free of foreign material such as grease and any debris which could inhibit adhesion. This may require cleaning with a broom or blower.
- Fasten insulation per current Firestone technical specifications to provide a proper substrate.
- Install UltraPly TPO SA membrane only when ambient and substrate temperatures exceed 20 °F (-7 °C) and rising. Do not install UltraPly TPO SA below this minimum temperature.
- Apply Single-Ply QuickPrime Primer or Single-Ply LVOC Primer to vertical surfaces before installing flashing membrane.
- Unroll and position the membrane over the substrate to achieve the desired alignment and overlaps. Allow membrane to relax before positioning and adhering. NOTE: Once membrane has fully relaxed, follow application methods below to adhere the membrane to the approved substrate.
- Method of Application
Field Membrane Application (Steps 1-5):
- Once the membrane has relaxed in place a minimum of 30 minutes (longer in colder weather), and the seam positions are aligned, carefully fold the sheet back approximately 10' (3.05 m) from one end to expose the release liner without disturbing the original position of the membrane. NOTE: Fold the membrane back from the end, not from the side.
- Starting from the center split of the exposed release liner, remove the liner at a 45° angle from the center of the sheet back beyond the membrane edge. Be sure to pull enough of the release liner to hold below the membrane. Remove at least 5' (1.5 m) of release liner from one end of the sheet and adhere it to the substrate. The removed liner should extend at a 45° angle beyond the edges of the membrane.
- Keeping the membrane flat and secured, and the seam overlap aligned, continue removing the release liner at a 45° angle along the entire length of the sheet; up to 100' (30.5 m). Pulling the release liner at a higher angle can cause the sheet to move and may trap air. The two halves of the release liner should be pulled out at the same time by two people. Keep the release liner as close to the roof surface as possible during removal. NOTE: Removal of the liner and any handling of the exposed SA adhesive should be completed by two persons minimum.
- To initiate adhesion, use a stiff bristled broom and apply downward pressure across the installed membrane. Broom the membrane from the center of the sheet working toward the edge.
- Roll the installed membrane with a weighted roller (5 lb per lineal inch) across the width of the sheet to ensure full contact with the substrate. NOTE: Do not roll membrane in place with a weighted roller if installed over ISOGARDTM HD or Resista / ISOGARD CG.
