PART 3 EXECUTION
8

3.01 GENERAL
A. Comply with the manufacturer's published instructions for the installation of the membrane roofing system,
including proper substrate preparation, jobsite considerations, and weather restrictions.
B. Position sheets to accommodate contours of the roof deck and shingle splices to avoid bucking water.
3.02 VAPOR RETARDERS
A. General:
The use of a vapor retarder to protect insulation and reduce moisture accumulation within an insulated
roofing assembly should be investigated, especially on projects with high interior humidity, such as,
swimming pools, breweries, pulp mills, etc.
B. In the generally temperate climate of the United States, during the winter months, water vapor flows
upward from a heated, more humid interior toward a colder, drier exterior. Vapor retarders are more
commonly required in northern climates than in southern regions, where downward vapor pressure may be
expected and the roofing membrane itself becomes the vapor retarder.
C. On cold storage/freezer facilities, the perimeter details must be selected to provide an air seal and prevent
outside air from infiltrating and condensing within the roofing assembly.
D. Consult the latest publications by ASHRAE (American Society of Heating, Refrigerating and
Air-Conditioning Engineers, Inc.) and NRCA (National Roofing Contractors Association) for specific
information.
E. If insulation is to be adhered to the vapor retarder with Flexible FAST Adhesive, the 725TR vapor retarder
must be compatible and shall be fully adhered to the substrate. Available products include Carlisle supplied
"peel and stick" rubberized asphalt membrane with compatible film coating (Carlisle VapAir Seal 725TR
Air and Vapor Barrier), and spray or roller applied butyl coatings. Installation requirements for Carlisle's
VapAir Seal 725TR Air and Vapor Barrier are identified in Carlisle's published specification.
F. VapAir Seal 725 TR Installation:
1. Surface Preparation: The concrete surface shall be completely dry; dryness shall be determined by a qualified
owner's representative. The surface shall have a smooth finish and be free of voids, spalled areas, sharp
protrusions, loose aggregate, laitance and form-release agents. Some curing compounds may interfere with
proper adhesion, so an adhesion test is recommended. In the event of rain, concrete must be allowed to dry
before the application of primer. Artificial drying methods such as torches are not acceptable.
2. Adhesive: Surfaces to receive VapAir Seal 725TR must be clean and dry. Use of CAV-GRIP III, CCW-702 or
CCW-702LV is required on all substrates. Approved Carlisle adhesives for attaching insulation to VapAir Seal
725TR are: Flexible FAST Adhesive and OlyBond 500.
3. Application: VapAir Seal 725TR material must be stored and kept above 60 degreesF prior to installation. Apply
VapAir Seal 725TR from low to high points in a shingle fashion so that the laps will shed water. Overlap all
edges by at least 2". End laps should be staggered. Position the membrane carefully to avoid fish-mouths and
wrinkles. Roll the VapAir Seal 725TR membrane immediately after installation with a 100 - 150-pound roller
wrapped in a resilient material. When the VapAir Seal 725TR is applied to a vertical surface, hand-rolling with
a2" or 4" hand roller is required. Vertical surfaces must be prepared inthe same fashion as horizontal surfaces
9

3.03 INSULATION PLACEMENT
A. Install insulation or membrane underlayment over the substrate with boards butted tightly together with no
joints or gaps greater than 1/4 inch. Stagger joints both horizontally and vertically if multiple layers are
provided.
B. Secure insulation to the substrate with the required mechanical fasteners or insulation adhesive Carlisle
Flexible FAST Adhesive in accordance with the manufacturer's specifications.
3.04 MEMBRANE PLACEMENT AND BONDING
A. Unroll and position the membrane without stretching. Allow the membrane to relax for approximately 1/2
hour before bonding. Fold the sheet back onto itself so half the underside of the membrane is exposed.
B. Apply the Bonding Adhesive in accordance with the manufacturer's published instructions and coverage
rates, to both the underside of the membrane and the substrate. Allow the adhesive to dry until it is tacky
but will not string or stick to a dry finger touch.
1. Roll the coated membrane into the coated substrate while avoiding wrinkles. Brush down the bonded
half of the membrane sheet with a soft bristle push broom to achieve maximum contact.
2. Fold back the unbonded half of the membrane sheet and repeat the bonding procedure.
C. Install adjoining membrane sheets in the same manner, overlapping edges approximately 4 inches. Do not
apply bonding adhesive to the splice area.
3.05 MEMBRANE SPLICING
A. Position the membrane sheet to allow for the required splice overlap. Mark the bottom sheets with an
indelible marker approximately 1/4" to 1/2" from the top sheet edge. The pre-marked line on the
membrane edge can also be used as a guide for positioning splice tape.
B. When the membrane is contaminated with dirt, fold the top sheet back and clean the dry splice area
(minimum 3" wide) of both membrane sheets by scrubbing with clean natural fiber rags saturated with
Sure-Seal Weathered Membrane Cleaner. When using Sure-Seal (black) PRE-KLEENED membrane,
cleaning the splice area is not required unless contaminated with field dirt or other residue.
C. Apply EPDM Primer to the splice area and permit to flash off. Primer must be applied to both the top
membrane layer and the bottom membrane layer.
D. When adhering Factory Applied Tape (FAT), pull the poly backing from FAT beneath the top sheet and
allow the top sheet to fall freely onto the exposed primed surface. Press the top sheet onto the bottom sheet
using firm even hand pressure across the splice towards the splice edge
E. For end laps, apply 3" or 6" SecurTAPE to the primed membrane surface in accordance with the
manufacturer's specifications. Remove the poly backing and roll the top sheet onto the mating surface.
F. Tape splices must be a minimum of 2-1/2" wide using 3" wide (Butyl/EPDM) SecurTAPE that is a
minimum 25-mil thick. SecurTAPE must extend 1/8" minimum to 1/2" maximum beyond the splice edge.
Field splices at roof drains must be located outside the drain sump.
Note: For projects where a 90-mil membrane OR a 20-year or longer System Warranty is specified,
splice enhancements are required. Refer to Carlisle Sure-Seal/Sure-White Roofing System Specification.
G. Immediately roll the splice using positive pressure when using a 2" wide steel roller. Roll across the splice
