Installing APP Torch Modified Bitumen in Cold Weather

Whenever possible, avoid installing when ambient temperatures are lower than 40 F to 45 F.

Membranes must be between 60 F and 80 F at the time of installation.

Primers, adhesives and sealants must be between 60 F and 80 F prior to use.

When installation must take place when the ambient temperature is lower than 40 F to 45 F, extra care must be taken to ensure the membrane does not crack while being unrolled and that adequate bonding is achieved.

Note: The above are general guidelines. Please consult the relevant Product Data Sheet (PDS) for more information about the specific product being used.
