          3.Pitch Pans shall be filled with non-shrinking grout to within 1 inch (25 mm) of the top of the pan. Allow the grout to dry and fill remainder of the pan with FTR-SLS pourable sealant.
          4.Pitch Pans and the sealant will require periodic maintenance by the building Owner's maintenance personnel.
          3.11EXPANSION JOINTS
          A.Flash all expansion joints in accordance with authorized details. Fasten all expansion joint material according to FiberTite specifications. Ensure the expansion material has sufficient material to expand to the widest point in expansion without causing undue stress on the expansion joint material.
          B.If the expansion joint is a preformed system, the manufacturer, description and a drawing illustrating the method of installation must be included when the (FTR-PIN) is submitted.
          A.Apply authorized sealants to all surface mounted reglets and per project requirements. Sealants are to shed water. Follow all manufacturer's instructions and installation guides.
          B.Use primer when recommended by the manufacturer.
          C.Sealants will require periodic maintenance by the building Owner's maintenance personnel.
          3.13TEMPORARY SEALS
          A.At the end of each working day or at the sign of rain, install temporary, 100 percent watertight seals where the completed new roofing adjoins the uncovered deck or existing roof surface.
          B.The Authorized Applicator shall create and maintain the temporary seal in such a manner to prevent water from traveling beneath the new or existing roof system.
          C.The use of plastic roofing cement is permissible when sealing to an existing built up roof.
          D.If water is allowed to enter beneath the newly completed roofing, the affected areas shall be removed and replaced at no additional expense to the building Owner.
          E.Prior to the commencement of work, cut out and remove all contaminated membrane, insulation, roof cement or sealant and properly dispose of offsite.
          A.FiberTite walkways and protection pads shall be installed at staging areas for rooftop equipment maintenance or areas subject to regular foot traffic.
          B.Walkway Installation:
          1.Roofing membrane to receive walkway material shall be clean and dry.
          2.Cut and position the FiberTite walkway material as directed by the specifications or agreement.
          3.Hot air weld the entire perimeter of the walk way to the previously cleaned FiberTite roofing membrane. Avoid excessive heating of the walk way material to prevent scorching the underlying roofing membrane.
          C.Protection Pad Installation:
          1.Roofing membrane to receive protection pad material shall be clean and dry.
          2.Prior to installing the FiberTite protection pads, 0.25 x 24 x 48 inch (6 x 610 x 1219 mm), weld a 6 x 6 inch (152 x 152 mm) strip of FiberTite membrane to each of the four corners of the back side of the pad. Position the strips in such a way that they overhang the edge of the pad a minimum of 2 inches (51 mm) around the 90-degree corner.
          3.Position the FiberTite protection pads as directed by the specifications or agreement and weld the visible portion of the previously applied stripping to the FiberTite roofing membrane.
          A.The installation of lightning protection must be coordinated with the Authorized FiberTite Applicator, certified lightning contractor and the building Owner.
          B.The lightning protection must be installed in such a manner that base plates, air terminals and cables do not penetrate the roofing membrane without the use of pre-approved flashing details.
          C.Cables and air terminals may be attached to the membrane using base plates and an approved construction adhesive. Contact FTS for specific adhesive recommendations.
          D.Recommendations regarding the selection of adhesives or alternative affixing of lightning protection systems to the FiberTite membrane does not in any way imply a warranty covering their performance or ability of the adhesives to remain affixed to the FiberTite membrane.
          A.Remove any and all debris, excess materials and scrap of any kind from the roof and surrounding premises prior to demobilization.
          B.Inspect all field welds, detailing and terminations to ensure a 100 percent watertight installation.
          A.Upon completion of the project, the Authorized Applicator shall register the completion of the project with FiberTite Technical Services. Upon receipt of the notice of completion, an FTS representative will schedule an inspection with a representative of the Authorized Applicator to thoroughly review the installation and verify compliance with Seaman Corporation specifications.
          B.Any corrections or modifications necessary for compliance with the specifications and acceptance for warranty (punch list) will be noted on the Final Inspection for Warranty Form.
          C.Upon completion of all punch list items and final acceptance of the installation, a warranty as authorized by the approved Seaman Corporation/FiberTite Project Registration will be issued.
