7 PART 3 EXECUTION GENERAL HENRY Company s General Requirements and Product Data are a part of this specification EXAMINATION OF SUBSTRATE Examine substrate to receive new roofing. Do not proceed with new roofing until adhesion has been verified by test patches, other preparatory work has been completed and unsatisfactory conditions have been corrected in a manner acceptable to HENRY. Notify Owner s Representative of any corrective action before proceeding with roofing. A. Treatment of Damaged/Deteriorated BUR : Any areas where BUR has blistered, buckled and/or become wet must be removed and repaired using similar products manufactured by membrane manufacturer. All areas where the BUR surface has significantly craze cracked (i.e., gaps in width and/or depth greater than 1/16 ) must be repaired using HE906 Flashmaster to bring the substrate to a smooth, workable surface. HE906 can be applied by either squeegee or brush when repairing craze cracks. B. Substrate Cleaning: Roof substrate must be carefully power washed with water. Pressure wash to remove all dirt, dust, chalking, loose materials, etc. Take care not to damage the roof surface or force water into the roof system. Use hot water and mild detergent to remove grease and/or oils from the roof substrate. If mildew or algae are present, use bleach to treat these areas, then pressure wash surface. C. Substrate must be clean, completely dry and free of any debris before application of HENRY products PREPARATION A. Power wash all existing smooth roof surfaces before proceeding. Scrub out any grease and dirt and other foreign matter that will interfere with adhesion of the coating. B. Repair defects: Splits, cracks, ridges, large blisters, deteriorated flashings, cracked metal edging and any other defect affecting waterproof integrity of the roofing system. See Henry Repair Guide. C. Repair, reinforce and resurface all flanges, roof penetrations and base flashings. D. Clean all drains of dried mastic and any other loose material and repair if required. E. Complete base flashings, drains and flanged penetrations prior to application of the emulsion and polyester. E. Reinforce all valleys and waterways with an extra layer of HE196 Polyester Fabric and HE902 or HE903 Adhesive. Extend ply at least 12 up inclines. Apply in the direction of the slope of the valley, lapping 4 on ends FLASHINGS A. Repair base and wall flashings. See General Requirements. Cover with asphalt emulsion and polyester following same procedures as the roof field. Extend polyester 6 inches onto field of roof. B. Install Flashing Specifications [#196], [#600] or [#180] where new flashings are required INSTALLATION REQUIREMENTS A.
