Application Guide Direction:
The membrane should be installed by means of a torch. Underneath of the membrane should be heated to a level that bitumen is melted superficially and the reinforcement layer is not disturbed.
Overlaps should be then reheated from the top and resealed with a trowel to ensure seam integrity.
Storage Conditions:
Store standing in closed conditions in (۵-۳۵) °C
