E2ZERO PE-Butyl Tape functions solely as a sealant and should not be used as a load-bearing connector. For a permanent connection, the substrates should be firm/taut, dry, smooth, and free of dust, sawdust, silicone and grease. Do not adhere to frozen surfaces. Surfaces must be suitable for permanent bonding. If in doubt, an adhesion test is recommended to verify proper performance and durability of the bond. The greater the pressure applied, the better the performance of the tape.

Note: Always confirm compliance with local building requirements prior to installation.
