. a • � � Technical Department. Penetrations � Mule-Hide Heat-Weld Membranes must be mechanically attached at all penetrations. See details for � specific methods of attachment. Curbs, Vents, and Roof-to-Wall Flashings . _ � Install Mule-Hide fasteners and plates as required around these penetrations. Using the Mule-Hide Reinforced Heat-Weld Membrane cut out flashings as required. All Heat-Weld Membrane flashings � shall be fully adhered using Mule-Hide's Bonding Adhesive. The following conditions must be met: 1. All surfaces to be fully adhered should be compatible, dry and smooth with no excessive surface � roughness. If an existing asphalt surface is present, one-half inch minimum piywood, 9 oz. polyester slipsheet or.26 gauge minimum galvanized metal barrier must be placed over the asphaltic surface. 2. After the proper surface has been prepared, Mule-Hide's Bonding Adhesive shall be applied using � a minimum 1/2 inch nap paint roller at a rate of approximately 2-1/2 gallons per 200 square feet of surface area depending on the type of substrate. Apply adhesive in smooth even coat, avoiding � globs, puddles, or other types of irregularities. Adhesive should be applied to the area of substrate to be flashed. Let adhesive dry sufficiently to produce strings when touched with a dry, clean finger. Mule-Hide Heat-Weld Membranes used as � flashing shall be cut to a workable length and shall have an even coating of Bonding Adhesive applied to it at a rate of approximately 1/2 gallon per 100 square feet. Carefully roll onto the � previously coated substrate after the adhesive coating the membrane has dried sufficiently as indicated above. Coverage rates will vary depending on substrate and environmental conditions. � Avoid wrinkling membrane when applying to substr�te. The amount of adhesive that can be successfully applied to the membrane will vary depending on ambient temperatures, humidity and � manpower. After mating membrane to the substrate, carefully roll the membrane with a 2-inch wide rubber hand roller to promote maximum positive contact between the membrane and the substrate. Overlap all adjacent flashing sheets a minimum of 2 inches. The Heat-Weld Membrane � Flashings shall extend a minimum of 6 inches onto the field sheet and be adhered securely. There shall be a minimum 2 inches hot-air weld in front of the fastener plates. All side laps are to overlap a minimum of 2 inches. Areas of the flashings and membrane to be welded are not to have Membrane Adhesive � applied to them. All flashings shall extend a minimum of 8 inches above roof inembrane level unless previously � accepted by the owner or his representative and the Mule-Hide Technical Departrrment. All flashings shall be hot air welded at their connections with the roofing membrane. Apply Edge Sealant at all � welded edges of flashings. All flashings shall be properly terminated according to mule-Hide's published Standard Details. NOTE: After flashing is adhered in place, promote full con#act adhesion by going back over entire area with a 2-inch rubber hand roller. � Roof Drains �' Install roof drains according to the Standard Details. Field seams must not run through drains. In � reroofing, old drains must be "thorouqhlv cleaned" or replaced. Existing sealing materials must be completely removed to avoid contamination and interference with the new membrane seal and with � �
