APPLICATION
1. Bonding surfaces must be free of moisture, dirt, or any contaminants. Any previously applied
asphalt, caulking, or sealants must be removed from the penetration(s).
2. Clean all surfaces with Flex's Weathered Membrane Cleaner.
3. Fill any voids in the roof deck around the penetration(s) to prevent sealant from seeping through
roof.
4. Flex Sealant Primer is required. Apply the primer to all bonding surfaces including penetration(s),
TPO membrane, inside walls and rim of the Flex TPO Molded Sealant Pocket. Allow primer to dry.
5. Remove cap from 0.5-gallon (2-liter) pouch and pour Flex Thermoplastic One-Part Pourable Sealer
directly into pocket. Fill pocket completely until rim is covered with Thermoplastic One-Part
Pourable Sealer making sure all voids are filled.
· To save unused sealant, squeeze air from pouch and replace cap. Unused sealant should be used
within 30 days.
· For best results maintain this product at room temperature before application.
· For cold weather applications remove any frost or moisture from inside pocket using a hand held
heat gun. Proceed with installation steps for the appropriate product.
COVERAGE
One 0.5-gallon pouch (2-liter) will fill 122 cubic inches of volume within a sealant pocket. One Flex TPO
Molded Sealant Pocket will require 0.46 gallons (1.75 liters) to fill completely (with no penetrations).
