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
