Direct -to -Deck with Mechanically Fastened Roof Covers: All self -adhering materials, with the exception of Polystick TU Plus, Polyflex SAP or SAP FIR and Mule -Hide SA-APP Cap Sheet or SA-APP Cap Sheet (FR) should be back -nailed in selvage edge seam in accordance with Polyglass / Mule - Hide Back Nailing Guide. Nails shall be corrosion resistant, 11 gauge ring -shank type with a minimum 1-inch diameter metal disk or Simplex type metal cap nail, at a minimum rate of 12" o.c. Polystick TU Plus should be back -nailed using the above noted fasteners and spacing, in area marked "nail area, area para clavar" on the face of membrane. The head lap membrane is to cover the area being back -nailed. All seal -lap seams (selvage laps) must be firmly rolled with a minimum 28 lb. hand roller to ensure full contact and adhesion. For Dual Pro and Tile Pro, align the edge of the top sheet to the end of the glue pattern (the sheet will overlap the fabric). View of Ovelap Seam of Dual Pro and Tile Pro All over -fabric and over -granule end -laps shall have a 6-inch wide, uniform layer of Polyplus 50 Premium Modified Wet/Dry Cement or Polyglass PG500 Modified Cement applied in between the application of the lap. Polystick TU Plus, Dual Pro and Tile Pro may not be used in any exposed application such as crickets, exposed valleys, or exposed roof to wall details Repair of Polystick membranes is to be accomplished by applying Polyplus 50 Premium Modified Wet/Dry Cement or Polyglass PG500 Modified Cement to the area in need of repair, followed by a minimum 6 x 6 inch patch of the Polystick material of like kind, set and hand rolled in place over the repair area. Patch laps, if needed, shall be installed in a water shedding manner. All Polystick membranes shall be installed to: ensure full contact with approved substrates. Polyglass requires a minimum of 40-lb weighted -roller or, on steep! slopes, use of a stiff broom with approximately 40-lbs of load applied for the field membrane. Hand rollers are acceptable for rolling of patches, laps (min. 28 lb roller) or small areas of the roof that are not accessible to a large roller or broom. 6.4.3 Tile Applications (not allowed for Polystick Du6i Pro, IR Xe or Polystick MU X): Reference is made to FRSA/TRI April 2012 (04-12) Installation Manual and Table 1 herein, using the instructions noted above as a guideline. For mechanically fastened the roofing over 2-ply system, consisting of Base Sheet and self -adhering top sheet(s), Base Sheet fastening shall be not less than FRSA/TRI April 2012 (04-12), Table 1. For adhesive -set the applications, refer to Section 5.6.4 herein. For nail -on the systems over Polystick MTS, battens are required for loading / staging of the tile. 6.4.4 Two (2) Ply Underlayment Systems: Polystick MTS followed by Polystick MTS, TU�P, TU Plus, TU Max, Tile Pro, MU-X or Polyflex SAP is allowable for use under mechanically attached prepared roof systems. Limits of use are those associated with the top -layer material. This is not a requirement, but is allowable if a'2-ply underlayment system is desired. Exterior Research and Design, LLC.
