COLD-APPLIED MEMBRANE ADHESIVE
**************************************************************************
NOTE: Materials standards and application
requirements vary for cold applied membrane
adhesives. Ensure product data and application
instructions are included under "Submittals" when
cold-process membrane applications are specified.
This information will be referenced by the field
personnel in monitoring the application process.
Consider low VOC adhesives for cold-process
applications on occupied buildings and when
otherwise necessary.
**************************************************************************
Membrane manufacturer's recommended [low volatile organic compound (VOC)]
cold process adhesive for application of the membrane plies.

MEMBRANE SURFACING
**************************************************************************
NOTE: Coordinate surfacing requirements with the
type of system specified in paragraph entitled
"Description of Roof Membrane System".
Factory-applied granule surfaced membrane shall be
specified except under non-typical conditions where
aggregate or coating applications may be considered.
Factory-applied granules or aggregate surfacing
should be used where possible. Specify required
finished membrane surfacing. Delete other options.
**************************************************************************
Modified bitumen roof membrane cap sheet shall have factory-applied granule
surfacing of [light][______] color [as selected from membrane
manufacturer's standard colors].[ Provide modified bitumen membrane
manufacturer's recommended field-applied protective coating of
[white][light gray][______] color. [Aluminized coating shall comply with
ASTM D 2824 or ASTM D 6848, Type I or III, as recommended by the modified
bitumen roof membrane manufacturer].][ Light colored, opaque water-worn
gravel aggregate surfacing material conforming to ASTM D 1863, or other
aggregate as recommended by the membrane manufacturer and approved by the
Contracting Officer[, and applied in flood coat of hot asphalt].]
]2.6
PRIMER
ASTM D 41, or other primer compatible with the application and as approved
in writing by the modified bitumen membrane manufacturer.
2.7
MODIFIED BITUMEN ROOF CEMENT
ASTM D 4586, Type II for vertical surfaces, Type I for horizontal surfaces,
compatible with the modified bitumen roof membrane and as recommended by
the modified bitumen membrane manufacturer.
