INDIAN RIVER COUNTY — NORTH COUNTY REGIONAL PARK PAGE 15 <br />AQUATIC FACILITY ROOFING REPLACEMENT SECTION 075216 <br />JUNE 7, 2019 MODIFIED BITUMINOUS MEMBRANE ROOFING <br />4. Apply base ply to the prepared substrate utilizing minimum 3 inch side and end laps. <br />Apply each sheet directly behind torch or adhesive applicator. Stagger end laps <br />minimum 3 feet. <br />5. Fully bond the cap sheets to base ply utilizing minimum 3 inch side and end laps. <br />Apply each sheet directly behind torch or adhesive applicator. Stagger side laps in <br />finish ply minimum 12 inches from side laps in underlying base ply. Stagger end laps <br />in cap sheet minimum 3 feet from end laps in underlying base plies. <br />6. Broadcast granules over all torched bitumen or adhesive overruns and squeeze out on <br />finish ply surface while torched bitumen is hot or adhesive still wet to ensure a <br />monolithic surface. <br />7. PMMA FLASHING INSTALLATION <br />a. Using masking tape, mask the perimeter of the area to receive the flashing <br />system. Apply resin primer to substrates requiring additional preparation and <br />allow primer to cure. <br />b. Pre-cut fleece to ensure a proper fit at transitions and corners prior to <br />membrane application. <br />c. Apply an even, generous base coat of flashing resin to prepared surfaces using <br />a roller at the rate specified by the resin manufacturer. Work the fleece into the <br />wet, catalyzed resin using a brush or roller to fully embed the fleece in the resin <br />and remove trapped air. Lap fleece layers a minimum of 2 inch (5 cm) and <br />apply an additional coat of catalyzed resin between layers of overlapping <br />fleece. Again using a roller, apply an even top coat of catalyzed resin <br />immediately following embedment of the fleece at the rate specified by the resin <br />manufacturer, ensuring that the fleece is fully saturated. Ensure that the <br />flashing resin is applied to extend beyond the fleece (maximum %-inch (6 mm)). <br />Remove the tape before the catalyzed resin cures. Make allowances for waste, <br />including saturation of roller covers and application equipment. <br />8. Miscellaneous Roof Penetrations: Treat as described above for vertical termination or <br />PMMA flashing membrane, prefabricated flashing boot or formed lead flashing. No <br />pitch pockets allowed. <br />3.5 FIELD QUALITY CONTROL <br />A.
