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.  Carlisle recommends a test weld sample be made from a piece of scrap TPO to eliminate the need to remove a section from a completed seam. 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.
3.8	MEMBRANE PLACEMENT AND ATTACHMENT (FleeceBACK Fully Adhered)

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.
3.9	MEMBRANE PLACEMENT AND ATTACHMENT (Mechanically Attached)
A.	Unroll and position membrane without stretching.  Allow the membrane to relax for approximately 1/2 hour prior to attachment.  Provide and secure both perimeter and field membrane sheets in accordance with the manufacturer's most current specifications and details.

3.10	MEMBRANE 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.
3.11	SEAM WELDING
A.	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. 
B.	Hot-air weld membrane using an Automatic Hot Air Welding Machine or Hot Air Hand Welder in accordance with the manufacturer's current guidelines.  At all splice intersections, roll the seam with a silicone roller to ensure a continuous hot air welded seam.
C.	When utilizing membrane greater than 45-mil thickness, overlay all splice intersections with Sure-Weld T-Joint Cover.
D.	Probe all seams once the hot air welds have thoroughly cooled (approximately 30 minutes).
E.	Repair all seam deficiencies the same day they are discovered.
F.	Apply Cut Edge Sealant on all cut edges of reinforced membrane (where the scrim reinforcement is exposed) after seam probing is complete.  Cut Edge Sealant is not required on vertical splices.
3.12	FLASHING
A.	Flashing of parapets, curbs, expansion joints and other parts of the roof must be performed using Sure-Weld reinforced membrane or prefabricated accessories.  Sure-Weld non-reinforced membrane may be used for flashing pipe penetrations, Sealant Pockets, and scuppers, as well as inside and outside corners, when the use of pre-molded or prefabricated accessories is not feasible.
B.	Follow manufacturer's typical flashing procedures for all wall, curb, and penetration flashing including metal edging/coping and roof drain applications.
C.	APEEL Protective Film should be removed and discarded after the completion of the roof system installation.  
D.	Sure-Weld Contour Rib Profiles:   
1.	The Contour Rib Profile is recommended for use with FleeceBACK TPO adhered roofing systems. 
2.	The Sure-Weld Contour Rib Profiles should be positioned parallel to the laps of the installed TPO roofing system and parallel with the roof slope where possible. 
3.	Ensure that all welding surfaces are clean and dry. Inspect all seam areas for proper weld prior to installing Sure-Weld Contour Rib Profile. 
4.	Contour Rib Profile spacing can be individually determined to achieve the desired appearance. 
5.	Connecting multiple ribs is achieved by using fiberglass pins. Insert a pin half-way into the end of one profile. Connect the adjoining rib by inserting the exposed end of the pin into the alignment hole. Repeat previous steps for additional TPO Contour Rib profiles.
3.13	WALKWAYS
A.	Install walkways at all traffic concentration points (such as roof hatches, access doors, rooftop ladders, etc.) and all locations as identified on the Contract Drawings.
B.	Hot-air weld walkway pads to the membrane in accordance with the manufacturer's current application guidelines.
