Leakage and distress in buildings clad with Exterior Insulation and Finish Systems (EIFS) is often the result of incorrect installation. Dave Finley (Cleveland) gives a brief overview of EIFS and describes some of the typical issues that cause distress, including: poor installation of weather resistive barriers and flashings, poor installation of reinforcing mesh, improper base coat application and curing, improper placement of insulation boards, and improper sealant installation. He explains the common long-term repairs used to address these conditions as well as the limitations of these repairs for both drained and barrier EIFS.
