FLEX TPO MOLDED SEALANT POCKET

PRODUCT DESCRIPTION

The Flex TPO Molded Sealant Pocket consists of an interlocking, two-piece, injection molded flexible
pocket with a rigid polypropylene vertical wall and pre-formed deck flanges. This product, in conjunction
with Flex TPO Primer and Flex TPO Molded Pocket Sealant, is used to waterproof pipe clusters or other
odd shaped penetrations on Flex TPO Roofing Systems.

PHYSICAL PROPERTIES
Size: 11.5” to 7.5” by 6” oval (29cm-19 cm by 15 cm)

Packaging: 5 pockets/carton
Weight (each): 0.75 lbs. (0.25 kg)
Material: Injection TPO Molded
Color: White, Gray or Tan

INSTALLATION:

1. Clean the inside of the Flex TPO Molded Sealant Pocket as well as the areas where the pocket
overlaps, the underside of the pocket flange and the deck membrane with Weathered Membrane
Cleaner. (Use a Scotch Brite Pad with the cleaner if the membrane has been exposed for an
extended period of time).

2. Place the Flex TPO Molded Sealant Pocket around penetration(s), overlapping the two sections of
the pocket.

3. Cut a piece of cardboard (approximately 4”x 4”) and place between the overlapping area of the
TPO Molded Sealant Pocket and the deck membrane. The cardboard prevents the pocket from
welding to the membrane when first welding the overlaps.

4. Using a hand-welder, weld the angle change in overlap area. Using the end of seam probe assists
in this process. (The hand-welder temperature setting should be between 5and 6).

5. Hand-weld the remainder of the horizontal overlap.

6. Repeat steps 4 and 5 to weld the overlap on the other side of the Flex TPO Molded Sealant Pocket.

7. Position the Flex TPO Molded Sealant Pocket so the vertical overlap is against the penetration.
This will allow proper pressure to be applied to the overlap with the 2-inch silicone roller.

8. Weld both vertical overlaps starting at the angle change and progressing to the top of the pocket.

9. Make tack-welds on all four sides of the pocket to hold it in place.

10. Weld the entire horizontal flange to the deck membrane.

11. Using a seam probe, check all splices for voids and cold-welds. Make any needed repairs.

12. Apply a thin coat of Flex TPO Primer to the inside and around the top rim of the pocket, to the
deck membrane enclosed by the pocket and to the penetration using a small paint brush.

13. Fill the pocket with sealant. Use an adequate amount of sealant to ensure that contact is made
with the top rim of the pocket.

CAUTIONS AND WARNINGS

· Temperature of penetration shall not exceed 160°F (71°C).

· The inside of the sealant pocket and all penetrations must be cleaned with Flex Weathered

Membrane Cleaner then coated with Flex TPO Primer prior to filling with sealant.
