. � � 1. Unroll the first full-width sheet membrane. Roll out the full-width Mule-Hide field sheet membrane so that it laps UNDER the second half-sheet by 5 in. This will produce a 2 to 2-1/2 in. clear lap area for seam welding. Position the butt end of the membrane so that it will be overlapped 5 in. by � the second half-sheet that will be installed perpendicular to the field sheets. NOTE: All field seams shall be shingled with the flow of v�ater. �j _ 2.. Allow the membrane to relax at least 15 minutes when the temperature is above 60°F prior to � fastening. 3. Fasten the field sheet. Mechanically fasten both edges and the butt end of the first field sheet into the deck. Take care to avoid making wrinkles. Fasteners must be installed so that the plates are �j 1/2 in. from the edges and end of field sheet. Space fasteners apart as required for the specific deck type and wind uplift requirements (see Section 4). 4. Install two more field sheets. These and subsequent rolls of field sheet membrane must � OVERLAP by 5 inches (to the scribed blue lap line) the previous runs of field sheet membrane. Align butt ends so that they will be overlapped 5 inches by the still-to-be-installed second � perpendicular half-sheet. Mechanically fasten field sheet into the deck along the edge that does not overlap the previous sheet, as well as the butt end. Space fasteners apart as indicated for the specific deck type and wind uplift requirements. � 5. Roll the first half-sheet back into place. The first half-sheet should overlap the second half-sheet by 5 inches. Then roll the second half-sheet back; it should overlap the first field sheet by 5 inches. � 6. Hot-air weld the half-sheets and the field sheets. Using the hot-air welding machine, wells all overlapping edges of the membrane together. � NOTE: In the subsequent hot-air welding operations we recommend hot-air welding the sheets together after installing a group of three full field sheets. � Perpendicular Half-Sheets - 1. Unroll and mechanically fasten perpendicular half-sheets. To install half-sheets that are ,� perpendicular to the field sheets, follow the same general procedure that was used with the first two half-sheets. As noted previously, the second perpendicular half-sheet must overlap the field sheet butt ends by 5 inches. This overlap will produce a 2 to 2 1/2 inch clear lap area for seam i� welding. 1. NOTE: The two perpendicular half-sheets must overlap the two previously installed half-sheets, ' and must run out to the edge of the roof, to the metal fascia clip position. � 2. Hot-air weld the sheets together. Weld the sheets together using the hot-air welding machine. _ Take care to avoid making wrinkles. �� 3. Probe all seams. Seams may be checked when cool. For best results, checking seams 8 hours �� after hot-air welding is recommended. Repair anyvoids found the same day. After probing and all !-� necessary repairs have been made, caulk all cut edges of reinforced membrane with Mule-Hide Edge Sealant. � NOTE: Pay special attention to the "T" lap seams formed where the second perpendicular half- sheet overlaps the butt ends of the field sheets. To ensure proper seaming of the "T" joints for 50 �- and 60 mil membrane, the top layer of the Heat-Weld Membrane is creased a minimum of one I� inch into the lower layer of inembrane by using a heat gun with a narrow or pencil tip nozzle and a rubber hand roller. By inserting a heat gun nozzle between the layers of the membrane, the � i�
