Will it stick? Will it stay stuck? Is a sealant and adhesive? Our world increasingly sees a bevy of tapes and sticky goo as solutions for penetrations, transitions, connections, fenestrations, and other problematic places. The formulations vary widely and understanding what they all do and how they do it can be daunting. We will talk about the concepts of adhesion, crack propagation, polymers, intermingling, entanglement, and force dissipation. We will look at real world practical applications and solutions, discuss compatibility of materials, and draw on our experience over hundreds of installations to share best practices and strategies for identifying what solutions will stick!

Learning Objectives:

By attending this session, attendees will:

Become familiar with the basic formulations of common flashing adhesives and understand the fundamentals of how adhesion works and why it fails
Understand what to look for in adhesive products for specific flashing applications
Review best practices along with some do's and don'ts of flashings
