CAUTIONS AND WARNINGS
1. The Flex Elvaloy® KEE T-Joint Cover is not intended for use to overlay fasteners and plates as
this requires the use of reinforced membrane.
2. Store Flex Elvaloy® KEE T-Joint Covers in a cool, shaded area and cover with light colored,
breathable, waterproof tarpaulins.
INSTALLATION
1. Clean splice intersection area with Flex 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
Elvaloy® KEE T- Joint Covers.)
3. Center the Flex Elvaloy® KEE 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.
