Application Recommendations
1. Install one ply of TRIPLY #75 Base Sheet over the perlife simultane-
ously attaching the base sheet and isulation to the deck using TRIPLY
screws and plates. The side laps must be a minimum of 3 inches. The
end laps must be a minimum of 4 inches.
2. Starting at the low point of the roof surface, set the TRIPLY TP-4 roll in
the course to be followed and unroll half the roll where practical. Position
the membrane to provide a minimum of 3 inch side laps and a 6 inch 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). The side lap and the end lap areas of the pre-
viously 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 membrane 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 genera-
tion of heavy smoke is an indications 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 1/4 inch flow out of modified
bitumen compound is required at all seams. Field seams should not be
troweled.
3. For smooth surfaced installation a coating is required, between 1 and 4
weeks after the installation, apply TRIPLY Premium Alumnium Roof
Coating at a rate of approximately 1 1/2-2 gallons per 100 square feet. The
TRIPLY 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 TRIPLY #75 Base Sheet over the perlife simultane-
ously attaching the base sheet and isulation to the deck using TRIPLY
®
screws and plates. The side laps must be a minimum of 3 inches. The
end laps must be a minimum of 4 inches.
2. Starting at the low point of the roof surface, set the TRIPLY TP-4-G roll
in the course to be followed and unroll half the roll where practical.
Position the membrane to provide a minimum of 3 inch side laps and a 6
inch 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 applica-
tion temperature (approximately 350˚ F). The side lap and the end lap
areas of the previously applied sheet must also be heated to provide prop-
er adhesion. The plastic film must be melted off the selvage edge of gran-
ule 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 sufficently 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 the same manner. A minimum of 1/4 inch flow out of modified bitu-
men compound is required at all seams. Field seams should not be trow-
eled. At the 6 inch minimum end laps, sufficient heat must be applied to
the granule surfaced TRIPLY Membranes to cause the granules to sink into
the top surface coating to assure a receptive surface for bonding to the
overlapping next roll of TRIPLY Membrane.
