diameter circle. Packaged in a box containing 100 covers. Available in white, tan and gray.

INSTALLATION
1. Clean splice intersection area with Flex Weathered Membrane Cleaner.
2. Use a lower temperature setting on the heat welder than compared to welding reinforced
membrane. (Typically a setting of “6” on a scale of “10” is appropriate for welding TPO T- Joint
Covers.)
3. Center the Flex TPO T-Joint Cover over the splice intersection. Begin welding at the center point
and work towards the outside. Use the edge of the roller to crease the T-Joint Cover into
membrane step-offs to achieve a proper seal.
4. Using a probe, check all splices for voids and cold-welds. Make any needed repairs.
CAUTIONS AND WARNINGS
· The Flex TPO T-Joint Cover is not intended for use to overlay fasteners and plates as this requires
the use of reinforced membrane.
· Store Flex TPO T-Joint Covers in a cool, shaded area and cover with light-colored, breathable,
waterproof tarpaulins. T-Joint Covers that have been exposed to the weather for 7 days or longer
prior to use must be prepared with Flex Weathered Membrane Cleaner before hot air welding.
