high point of the roof.
Precaution & Limitations
• Slippery when wet or covered by frost.
• Consistent with good roong practice, always wear fall protec-
tion when working on a roof deck.
• Release liners are slippery. Remove from work area immedi-
ately after membrane application.
• Do not leave permanently exposed to sunlight. Cover within 30
days.
• Do not fold over the roof edge unless the edge is protected by a
drip edge, gutter or other ashing material.
• Do not install on chamfered edges of wood plank.
• When lapping over granular, allow for 6 in. overlap and apply
bead of roong mastic along the edge of the Grace Roof Detail
Membrane.
• Repair holes, shmouths, tears and damage with a round patch
of membrane, extending past the damaged area 6 in. (150 mm)
in all directions.
If fasteners are removed leaving holes in the membrane, it must
be patched. The membrane may not self-seal open fastener
penetrations.
• Do not install fasteners through the membrane over unsup-
ported membrane areas of the structural deck, such as over the
joints between adjacent structural panels.
• Due to its slight asphaltic odor, do not apply where membrane
is exposed to interior living spaces. Refer to product literature
for more complete information.
• Not compatible with EPDM or TPO; use Grace Ultra
