          ** NOTE TO SPECIFIER ** Retain the next article if ONLY if membrane is Sure-Weld FULLY ADHERED
 
          3.6MEMBRANE PLACEMENT AND ATTACHMENT (Sure-Weld Fully Adhered)
 
          A.Position Sure-Weld membrane over the acceptable substrate. Fold membrane sheet back lengthwise so half the underside of the membrane is exposed.
 
          B.Apply approved Bonding Adhesive in accordance with the manufacturer's published instructions, to the exposed underside of the membrane and the corresponding substrate area. Do not apply Bonding Adhesive along the splice edge of the membrane to be hot air welded over the adjoining sheet. Allow the adhesive to dry until it is tacky but will not string or stick to a dry finger touch.
          1.Roll the coated membrane into the coated substrate while avoiding wrinkles. Brush down the bonded section of the membrane sheet immediately after rolling the membrane into the adhesive with a soft bristle push broom to achieve maximum contact.
          2.Fold back the unbonded half of the sheet lengthwise and repeat the bonding procedures.
 
          C.Position adjoining sheets to allow a minimum overlap of 2 inches.
 
          D.APEEL Protective Film should be removed from within areas that are to be heat-welded together. In areas that do not require heat welding, the APEEL Protective Film can be left in place for up to 90 days.
 
          E.Hot-air weld the Sure-Weld membrane sheets using the Automatic Hot Air Welding Machine or Hot Air Hand Welder in accordance with the manufacturer's hot air welding procedures.

          F.Continue to install adjoining membrane sheets in the same manner, overlapping edges a minimum of 2 inches and complete the bonding procedures as stated previously.
          ** NOTE TO SPECIFIER ** Retain the next article if ONLY if membrane is Sure-Weld SAT TPO FULLY ADHERED
 
          3.7MEMBRANE PLACEMENT AND ATTACHMENT (Sure-Weld SAT TPO Fully Adhered)
 
          A.Position Sure-Weld membrane over the acceptable substrate. Fold membrane sheet back lengthwise so half the underside of the membrane is exposed.
 
          B.Remove the release liner on one half of the sheet starting from the split in the liner at the middle of the sheet. The liner should be removed at an angle to reduce risk of splitting or tearing.
 
          C.Roll the membrane onto the substrate while avoiding wrinkles. To achieve the best adhesion, the membrane should be rolled onto the substrate at an angle with 150 lb weighted roller. When applying the Carlisle Sure-Weld SAT TPO membrane it is recommended to maintain a large curve on the leading edge of the membrane. This will help eliminate creases and bubbles that cannot be removed after the sheet is in place.
 
          D.Fold back the remaining half of the sheet and repeat the above process.
 
          E.Position adjoining sheets to allow a minimum overlap of 2 inches.
 
          F.Hot-air weld the Sure-Weld membrane sheets using the Automatic Hot Air Welding Machine or Hot Air Hand Welder in accordance with the manufacturer's hot air welding procedures.

At all splice intersections, roll the seam with a silicone roller to ensure a continuous hot air welded seam.
 
          G.Continue to install adjoining membrane sheets in the same manner, overlapping edges a minimum of 2 inches and complete the bonding procedures as stated previously.
          ** NOTE TO SPECIFIER ** Retain the next article if ONLY if membrane is FleeceBACK FULLY ADHERED
 
          3.8MEMBRANE PLACEMENT AND ATTACHMENT (FleeceBACK Fully Adhered)
 
          A.Position and unroll successive sheets and align to provide for a minimum 3 inch (76 mm) wide splice.
 
          B.Fold adjacent sheets in half lengthwise to expose an approximate 12 foot (3657 mm) wide substrate area.
 
          C.Membrane which will have the adjacent sheet spliced over it should be adhered to the substrate first. In this fashion, selvage edge splice area will not be contaminated by setting splice edge into the FAST Adhesive.
 
          D.Spray or extrude FAST Adhesive onto the substrate and allow to foam up approximately 1/8 inch (3 mm). Wait for the adhesive to achieve "string" when a small object is lifted out of the adhesive.
 
          E.Place the membrane into adhesive after adhesive develops strings when touched, typically 1-1/2 to 2 minutes after adhesive was applied and roll with a weighted roller. Add temporary weight and use relief cuts to ensure boards are well adhered.
 
          F.Apply FAST Adhesive to the substrate and continue process described above until all sheets are fully bonded, allowing for necessary splice overlaps at selvage edges. At end laps (along the width of the sheet) membrane shall be butted together which will be overlaid with 6 inch wide Sure-Weld Reinforced Membrane hot air welded along all edges. Pressure-Sensitive Cover strip is not permitted in this situation.
          ** NOTE TO SPECIFIER ** Retain the next article if ONLY if membrane is MECHANICALLY ATTACHED.
 
          3.9MEMBRANE PLACEMENT AND ATTACHMENT (Mechanically Attached)

          C.Install adjoining membrane sheets in the same manner in accordance with the manufacturer's current application requirements.
          ** NOTE TO SPECIFIER ** Retain the next article if ONLY if membrane is Sure-Weld AFX FleeceBACK Hot Mopped.
 
          3.10MEMBRANE PLACEMENT AND ATTACHMENT (Asphalt Adhered)
 
          A.General
          1.Store membrane in a dry area to prevent absorption of moisture in the fleece backing. If moisture is present, it must be removed with a wet-vac system and the membrane must be allowed to fully dry prior to membrane adhesion.
          2.The temperature of the asphalt during application must be within 25 F (4 C) of the EVT (Equiviscous Temperature). The manufacturer's heating instructions (i.e., maximum heating temperature, prolonged storage temperature guidelines) must be strictly followed.
          3.Apply asphalt at 18-22 pounds per square (100 square feet). It is important that "heavy spots" of asphalt, typically occurring at mopping overlaps or where the mop is first positioned, be avoided. At these areas, the asphalt must be spread evenly to avoid a heavy coverage rate that can cause asphalt saturation of the fleece backing. Asphalt saturation of the fleece must be avoided.
          4.If spreaders are used to apply asphalt, care must be taken to ensure the proper coverage rate is maintained. Do not overlap asphalt layers at multiple pass lines since the heavy coverage rate occurring at these overlapping areas must be avoided.
          5.Mopping the membrane directly to Polyisocyanurate insulation is not permitted. Carlisle HP Recovery Board must be used as an overlayment when insulation is specified. Carlisle Modified Base Sheet may be used in place of the Carlisle HP Recovery Board when fastened to a steel or wood deck following manufacturer's requirements for maximum 15-year warranty.
 
          B.When positioning membrane along the length for splices, allow the fleece backing to extend approximately 1/2 inch (13 mm) above adjoining membrane to avoid direct contact between TPO membrane and hot asphalt.
 
          C.When using a mop to apply asphalt, position the membrane over the substrate overlapping adjacent sheets to accommodate membrane splicing and fold in half lengthwise to expose the substrate and the back side of the membrane (full width of the membrane by approximately half the length).
 
          D.Beginning at the membrane fold, apply asphalt to the full width of the membrane extending a maximum of 4 to 5 feet while rolling the membrane into the asphalt immediately. The asphalt temperature at the time of membrane adhesion must be above 350 F (176 C). Continue to apply asphalt for the full width of the membrane extending 4 to 5 feet at a time while embedding the membrane into the asphalt until the entire half of the sheet is adhered. Fold back the unbonded half of the membrane and repeat the bonding procedures identified above.
 
          E.When using spreaders to apply asphalt, the membrane is folded widthwise dependent on the size of the spreader (36" - 57" wide); i.e., if a 36" wide spreader is used, the membrane will be folded to expose approximately a 36" wide by 50' long area. After the asphalt is applied in a single pass, the membrane is rolled into the asphalt. After mopping the membrane, apply asphalt to the remaining substrate area in single passes and continue to bond membrane as identified above.
          1.Membrane must be embedded into asphalt immediately after each spreader pass to ensure asphalt temperature is at least 350 F (176.7 C) at the time of membrane embedment.
          2.Take care that the asphalt is not dropped directly on the back of the membrane. Use a mop to spread asphalt at pass lines and under sheet folds to prevent a heavy coverage rate.
 
          F.After membrane mopping, immediately after adhesion, brush down the sheet with a soft bristled broom using light to medium pressure. Do not use weighted rollers or heavy pressure when brooming the membrane to avoid asphalt saturation of the fleece.
