This demonstrationvalidation project investigated the use of new corrosion-resistant mold-abatement coatings for interior building surfaces. The demonstration site was an office building at Fort Polk, LA, a continually warm, humid locale where profuse mold growth affects quality of life and imposes high maintenance costs. Three selected products, off-the-shelf interior paints formulated to prevent mold and mildew growth, were applied and compared with the performance of a standard interior coating that served as the experimental control. Each of three rooms was painted with one of the three demonstrated coatings, and one was painted with the control coating. Gypsum wallboard specimens were also prepared, coated, and mounted in a mechanical room for observation and evaluation. The buildings heating, ventilation, and air conditioning HVAC system was unexpectedly upgraded soon after the demonstration coatings were applied, apparently due to a scheduling change or miscommunication related to a planned future renovation. This improvement eliminated the mold-promoting environmental conditions inside the building, so no significant mold or fungal growth was observed over the 12 month evaluation period. Therefore, the project did not produce any conclusions about coating performance.
