摘要

The water resistance of the base coat in exterior insulation and finish systems (EIFSO is critical for overall system performance. ASTM E 331 is used to investigate the water resistance of PB EIFS specimens which incorporate different base coat thicknesses. Test results for specimens with and witnout finish coat are presented. It found that PB EIFS base coats in full compliance with recommended application requirements did not allow water intrusion at the industry-specified test pressure of 299 Pa (6.24 lbf/ft~2). Based on these test results, observations on the typical failure mode of specimens which allowed water intrusion are presented, and the implications of test results are discussed.
