General
Design and application instructions shall apply in addition to the following
recommendations and specifications. For additional information, call
1-800-766-3411.
Application Recommendations
1. Install one ply of Tri-Ply
®
#75 Base Sheet over the perlite simultane-
ously attaching the base sheet and insulation to the deck using
Drill-Tec
Screws and Plates. The side laps must be a minimum
of 3" (76 mm). The end laps must be a minimum of 4" (102 mm).
2. Starting at the low point of the roof surface, set the Tri-Ply
®
APP
Smooth Membrane in the course to be followed and unroll half the
roll where practical. Position the membrane to provide a minimum
of 3" (76 mm) side laps and a 6" (152 mm) end lap. Using the pro-
pane torch, apply the flame to the surface of the coiled portion of
the roll until the surface reaches the proper application temperature,
approximately 350 °F (177 °C). The side lap and the end lap areas
of the previously applied sheet must also be heated to provide
proper adhesion. The flame should be moved from side to side and
up the side lap area of the previously applied sheet. Unroll the mem-
brane while pressing onto the underlying surface. Be sure that the
surface of the roll is heated sufficiently so that the texture-backed
products lose their sharp definition. The generation of heavy smoke
is an indication that the surface is being overheated. When this half
of the roll is secure, reroll the other half of the roll and torch in place
in the same manner. A minimum of ¼" (6 mm) flow out of modified
bitumen compound is required at all seams. Field seams should not
be troweled.
3. For smooth-surface installation, a coating is required. Between 1
and 4 weeks after the installation, apply a premium aluminum roof
coating per the manufacturer’s instructions. The Tri-Ply
®
Membrane
surface must be clean, dry, and free of all loose dirt and dust at the
time of coating.

Application Recommendations
1. Install one ply of Tri-Ply

neously attaching the base sheet and insulation to the deck using

2. Starting at the low point of the roof surface, set the Tri-Ply
®
APP
Granule Membrane in the course to be followed and unroll half the
roll where practical. Position the membrane to provide a minimum
of 3" (76 mm) side laps and a 6" (152 mm) end lap. Using the
propane torch, apply the flame to the surface of the coiled portion
of the roll until the surface reaches the proper application tempera-
ture, approximately 350 °F (177 °C). The side lap and the end lap
areas of the previously applied sheet must also be heated to provide
proper adhesion. The plastic film must be melted off the selvage
edge of granule-surfaced products. The flame should be moved
from side to side and up the side lap area of the previously applied
sheet. Unroll the membrane while pressing onto the underlying
surface. Be sure that the surface of the roll is heated sufficiently
so that it develops a sheen. The generation of heavy smoke is an
indication that the surface is being overheated. When this half of
the roll is secure, reroll the other half of the roll and torch in place
in the same manner. A minimum of ¼" (6 mm) flow out of modified
bitumen compound is required at all seams. Field seams should not
be troweled.
3. At the 6" (152 mm) minimum end laps, sufficient heat must be
applied to the granule-surfaced Tri-Ply
®
Membranes to cause
the granules to sink into the top surface coating to ensure a
receptive surface for bonding to the overlapping next roll of
Tri-Ply
®
Membrane.
