TESTING ANTIMICROBIAL PAINT EFFICACY ON GYPSUM WALLBOARD CONTAMINATED WITH STACHYBOTRYS CHARTARUM. 10.1080/154596207017, M.S. Morgan (ed.), JOURNAL OF OCCUPATIONAL AND ENVIRONMENTAL HYGIENE.

Often mold contaminated building materials are not properly removed, some surface cleaning is performed and paint is applied in an attempt to alleviate the problem. The efficacy of antimicrobial paints to eliminate or control mold regrowth on surfaces can easily be tested on non-porous surfaces. However, the testing of antimicrobial efficacy on porous surfaces such as gypsum wallboard can be more complicated. The mold Stachybotrys chartarum has been found to be associated with idiopathic pulmonary hemorrhage in infants and has been studied for toxin production and its occurrence in water damaged buildings. Research to control S. chartarum growth using seven separate antimicrobial paints and two commonly used paints on contaminated gypsum wallboard has been performed in laboratory testing. The results indicate differences in antimicrobial efficacy for th period of testing.
