Hurricanes cause significant damage to residential construction due to water intrusion. While it is assumed that Portland cement-based exterior plaster (stucco) applied to concrete masonry construction increases the resistance to water penetration, a review of the literature has found no comprehensive tests on this subject. This research was undertaken to provide some information as to the effectiveness of stucco made with plastic (stucco) cement in the prevention of water intrusion through the concrete block and stucco wall system. Results of walls tested in accordance with ASTM E514-06 indicate significant protection against wind driven rain at various wind speeds up to and exceeding those of a Category 5 hurricane.
