PART 3 EXECUTION

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 MD Installation:

1. Surface Preparation: The surface shall have a smooth finish and be free of voids, spalled areas, sharp protrusions, loose aggregate, laitance, and form release agents. In the event of rain, concrete must be allowed to dry before primer is applied.

2. Primer: Surfaces to receive VapAir Seal MD Air and Vapor Barrier must be clean and dry. Prime with Cav-Grip III Primer. Apply Primer by spray, brush, or with a long nap roller at the applicable coverage rate noted above. At 75° F allow primer to dry 1 hour minimum. Primer has a satisfactory cure when it does not transfer when touched. Prime only areas to be waterproofed the same day. Re-prime if the area becomes dirty.

3. Application: Apply VapAir Seal MD Air and Vapor Barrier to the metal deck from low to high point, in a shingle fashion, so that laps will shed water. Overlap all edges at lease 2-1/2". End laps shall be staggered. Place either a 6” wide section of 24 gauge sheet metal or a 6” wide section of VapAir Seal MD directly on the metal under each end lap, perpendicular to the end lap, to ensure a solid surface to roll the end lap together. Seams and end laps must be rolled with a 2” seam roller or stand-up seam roller. Place the membrane carefully so as to avoid wrinkles and fish mouths. Immediately after installation, broom the sheet to ensure proper contact with the metal.

4. Insulation Installation: Ensure the surface of the VapAir Seal MD Air and Vapor Barrier is dry prior to installing insulation. Place insulation over the surface and mechanically fasten to the roof deck in accordance with this Carlisle Specification.

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 10 edge, not parallel to it. When FAT is used, Carlisle’s Stand-Up Seam Roller can be used to roll parallel to the splice edge.

H. At all field splice intersections, apply Lap Sealant along the edge of the membrane splice to cover the exposed SecurTAPE 2” in each direction from the splice intersection. Install Carlisle’s Pressure-Sensitive “T” Joint Covers or a 6” wide section (with rounded corners) of Sure-Seal Pressure-Sensitive Elastoform Flashing over the field splice intersection.

3.06 FLASHING

A. Wall and curb flashing shall be cured EPDM membrane. Continue the deck membrane as wall flashing where practicable. Use Pressure-Sensitive Curb Wrap when possible to flash curb units.

B. Follow manufacturer’s typical flashing procedures for all wall, curb, and penetration flashing, including metal edging/coping and roof drain applications.

3.07 WALKWAYS

A. Install walkways at all traffic concentration points (such as roof hatches, access doors, rooftop ladders, etc.) and all locations as identified on the specifier’s drawing.

B. Adhere walkway pads or rubber pavers to the EPDM membrane in accordance with the manufacturer’s specifications.
