1.Torch-applied method and cold adhesion method are both feasible for this kind of waterproofing membrane, or we can use these two methods together during the construction, which means cold adhesion method used at the main part and torch-applied method used at the seam.
2.torch-applied method:use spray guns or blowtorches to heat the membrane and the base surface.while the bitumen on membranes is melting, roll the membrane forward, then use roller to make the membranes and the base surface stick together.
3.cold adhesion method:brush adhesives on the base surface and membranes, after a while, pave the membranes, meanwhile press out the air with the roller until the membranes and the base surface stick together tightly and flat-wise.
Rainy, snowy or strong windy( more than five level) day is not suitable to pave membranes.
Air temperature should be above 0oC in the construction site.
In rainy days, keep the paved membranes from getting wet.
Heat the membranes evenly with fire from a proper distance until the surface of the membranes melt into bright black without overheating.
Safety facilities and fire-fighting equipment should be placed properly in site.
