PA-828 Flashing Cement is designed for use with roof systems as a membrane flashing adhesive and is slump resistant and highly flexible for high-slope and vertical applications. It can be applied using a notched trowel supplied by Siplast or with a standard V-notched trowel. To ensure proper adhesion, PA-828 Flashing Cement is applied to the back of the flashing sheet and to the substrate. Applications over irregular or porous substrates may require an approximate total of 2 1⁄2 to 4 gallons per square. Usage rate should be doubled over granule surfaces. Coverage rate may vary depending on ambient temperature, surface conditions, and applicator.
