Technology overview

What sealants & repair are

Most water intrusion begins at details: joints, penetrations, terminations and transitions. This family covers the sealants, mastics and repair materials used to treat those points and to make localized repairs to existing assemblies.

Products are selected to be compatible with the adjacent substrates and with the surrounding coating or membrane system. Joint design, movement capability and compatibility are confirmed against the current product data and specification.

Role in the system: The detailing and repair layer that keeps roofing, deck and envelope systems continuous at their most vulnerable points.
