Stagger joints both horizontally and vertically if multiple layers are provided. B. Base layer installed on slotted acoustical deck areas requires special attention to prevent adhesive from entering interior through deck slots. In the areas, adhesive is to be applied directly to the first layer of insulation board stock. When adhesives have reached "string time" boards are to be carefully laid in place. Wait approximately 2 minutes and then roll the insulation in place with weighted roller, as described in the manufacturer's specifications.

Stagger end joints between rows. 1. NO mechanical fasteners are allowed. B. Do not apply more cover board than can be covered with membrane in same day. FMDC No /PWA No ELASTOMERIC MEMBRANE ROOFING

8 3.04 MEMBRANE APPLICATION A. On phased roofing, when the completion of flashings and terminations is not achieved by the end of the work day, a daily seal must be performed to temporarily close the membrane to prevent water infiltration.complete an acceptable membrane seal in accordance with the manufacturer's requirements. B. Unroll and position 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. C. Apply the Bonding Adhesive in accordance with the manufacturer's published instructions, 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. D. Install adjoining membrane sheets in the same manner, overlapping edges approximately 4 inches. Do not apply bonding adhesive to the splice area. E. Shingle joints on sloped substrate in direction of drainage. F. Membrane splicing 1. Tape splices must be a minimum of 2-1/2" wide using 3" wide SecurTAPE extending 1/8" minimum to 1/2" maximum beyond the splice edge. (Factory-Applied Tape is also available.) Field splices at roof drains must be located outside the drain sump. 2. Position membrane sheet to allow for required splice overlap. Mark the bottom sheets with an indelible marker approximately 1/4" to 1/2" from the top sheet edge. The premarked line on the membrane edge can also be used as a guide for positioning splice tape. 3. 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 Primer. When using Sure-Seal (black) PRE-KLEENED membrane, cleaning the splice area is not required unless contaminated with field dirt or other residue. 4. Apply Sure-Seal HP 250 Primer to splice area. 5. Apply SecurT APE in accordance with the manufacturer's specifications and roll the top sheet onto the mating surface. 6. 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 top sheet on to the bottom sheet using firm even hand pressure across the splice towards the splice edge. 7. Immediately roll the splice using positive pressure when using a 2" wide steel roller. Roll across the splice 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. 8. 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 Flashing over the field splice intersection. G. Install 6 inch wide pressure sensitive cover strip over ALL seams, flashing joints, and flashing flanges. H. At intersections with vertical surfaces: 1. Extend membrane up a minimum of12, inches onto vertical surfaces. 2. Fully adhere flexible flashing over membrane and up to nailing strips or other means of securement recommended by Roofing System Manufacturer. 3. Secure flashings as recommended by Roofing System Manufacturer. I. Around roof penetrations, seal flanges and flashings with flexible flashing. J. Coordinate installation of roof drains and sumps and related flashings. FMDC No I PWA No ELASTOMERIC MEMBRANE ROOFING
