  • Do not apply on surfaces above 120° F or when rain is expected.

Priming

Tower Tech² ™ is generally considered a non-priming sealant. It is the user’s responsibility to check the
adhesion of the cured sealant on typical test joints at the project site before and during application
consult Technical Services for additional information.

Application

Tower Tech² ™ comes ready to use. U-shaped joints should have the proper size backer rod or bond
breaker tape installed to prevent 3 point adhesion. The sealant must reach deepest point of the joint.
Remove excess with a clean rag and water. Tooling the joint flush with a putty knife is recommended.
Tooling results in the correct bead shape, a neat joint, and maximum adhesion. 90° joints can be
tooled smooth with a moistened rag to a minimum bead size of 3/8”.

Clean up

  • Immediately after use, clean equipment with soap and water.
  • Remove cured sealant by cutting with a sharp-edged tool.
  • Remove thin films by abrading.
