Delete if not applicable. 3.4 TEMPORARY ROOF/VAPOR RETARDER INSTALLATION A. Install membrane in accordance manufacturer's current published specifications and recommendations for use as a temporary roof, vapor retarder or a base ply substrate for liquid-applied roofing/waterproofing. ** NOTE TO SPECIFIER ** Select required material from the following paragraphs and delete those that are not applicable. 1. Torch-Applied Attachment: a. Sanded Base Sheet OR Granule Surfaced Cap Sheet b. The substrate must be clean, smooth, dry and primed with Asphalt Primer to ensure proper adhesion of the membrane. Asphalt Primer should be allowed to completely dry before beginning installation of the membrane. c. On slopes less than 3/4" per foot install cap sheet perpendicular to the slope. d. Never apply membrane by any method except welding with a propane torch or other equipment specifically designed for application of torchable modified bitumen. e. The coiled membrane must be unrolled approximately 10 ft. and aligned. The propane torch flame is then applied uniformly across the exposed back surface of the membrane and lap areas until the compound reaches the proper application temperature and exhibits a slight sheen. A complete burn-off of release films where present on the underside of the rolls, membrane selvage edges or both surfaces is necessary. Avoid overheating which may result in damage to or improper adhesion of the membrane. (The flame should be moved from side to side in the shape of an "L", applying about 75% of the heat to the membrane and 25% to the substrate or underlying plies including the lap area of the previously installed courses.) The membrane is slowly unrolled as heat is applied to ensure proper adhesion. When complete, re-roll the opposite end of the membrane and install in the same manner. f. A minimum 1/4" (6 mm) bitumen flow-out must be obtained at all seam areas. Dry laps are not acceptable. To ensure the proper 1/4" (6 mm) flow of bitumen at the seam areas, a roller may be used. Roller application should follow behind the torch no more than 4 ft. (1.2 m) nor less than 3 ft. (0.91 m) to be sure that the membrane will be at the proper temperature to produce proper flow. Hand rollers or "walking-in the seam" methods are also acceptable. Check all seams for full and uniform adhesion. Un-adhered seams must be lifted with a heated trowel and resealed by lightly torching the seam area. g. All end laps must be staggered a minimum of 18" (45.7 cm) so that no adjacent end laps coincide. If end laps fall in line or are not staggered the proper distance, a full width of membrane must be installed over the end laps. h. All laps must be parallel or perpendicular to the slope of the roof such that the flow of water is never against the lap. 2. Cold-Process Adhered Attachment: a. Sanded Base Sheet OR Granule Surfaced Cap Sheet b. Stir the Asphalt Adhesive well, do not thin. c. The substrate must be clean, smooth, and dry. d. It is required that the ambient air temperature is above 50 degreesF for the use of adhesives. e. Do not apply adhesive if there is a possibility of freezing temperatures within 24 hours of installation. Adhesive should not be applied to substrates with temperatures over 140 degreesF. f. Apply the adhesive so that the substrate is covered wider than the membrane being installed. The adhesive can be applied by squeegee or spray application. Pour the adhesive on the substrate and spread it, using a 3/16" (5 mm) or maximum 1/4" (6 mm) serrated squeegee, apply adhesive per manufacturer requirements without exceeding the maximum rate. g. End laps and selvage laps of the membrane being lapped must be coated with adhesive so that a visible bead of adhesive appears. Roll all laps with steel roller to ensure proper adhesion. h. Allow sufficient time after membrane installation for solvent evaporation before heat seaming of laps. i. Apply adhesive so that a small bead shows at the edge of the membrane. Do not allow heavy flows of adhesive to extend beyond the membrane edge. j. In the event a wrinkle or a "fishmouth" forms during the application of the membrane, do not "walk it down" as the memory of the sheet or felt may cause it to reappear. Fishmouths or wrinkles shall be sliced open and patched with cold adhesive and additional membranes. k. Install full width membrane, lapping 2" (5 cm) on the sides and 4" (10 cm) on ends. Stagger adjacent end laps a minimum of 12" (30.5 cm) apart. l. Workmen must stand on the insulation or deck side of the system and avoid traffic on the freshly laid membrane system for a long enough time to allow the adhesive to set up. Do not allow equipment to stand over, or store materials on, the freshly laid membrane. Dispensing equipment must have balloon tires. m. Allow additional time after completion of the cold process membrane installation before applying the Cold-Liquid Applied Membrane System. 3. Self-Adhered Attachment: a. Sanded Base Sheet OR Granule Surfaced Cap Sheet b. The substrate must be clean, smooth, dry and primed with Acrylic SA Primer to ensure proper adhesion of the membrane. Acrylic SA Primer should be allowed to completely dry before beginning installation of the membrane. c. Roll out membrane and allow the base to relax prior to application. Cut rolls into manageable lengths for best results. d. Fold the membrane back halfway lengthwise to remove the half of the poly release film on the underside from the up-slope side of the roll and set in place. Then flip back the other half of the roll and remove the down slope side of the second half of the release film on the underside of the roll in a smooth continuous process. When removing the poly release film from the underside of the roll, you should intend to simultaneously bond the side lap together. e. Firmly adhere the membrane by direct contact pressure to the desired substrate. Apply pressure from the center of the sheet outwards towards the membrane sides and ends. f. Use a weighted field roller to assure maximum contact of the membrane with the substrate working out all air pockets, voids and un-adhered areas that will prevent bonding of membrane to underlying substrate. g. Continue installing the membrane up slope lapping the side laps 4" (10.1 cm) and 6" (15.2 cm) on the end laps. Stagger all end laps a minimum of 18" (45.7 cm) from one another. h. Check all joints and laps for full adhesion before the end of each day. If the membrane can be lifted in any area, it is not properly adhered. A seam probing tool can be helpful to check for small voids at laps. i.
