All self -adhering materials, with the exception of Polystick TU Plus, Polyflex SAP or SAP FR 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, it 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) Imust 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 PG50o Modified Cement applied in between the application of the lap. Polystick TU Plus, Dual Pro and TilePro 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-Ibs of load applied for the field membrane. Hand roller's 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.
