Mold Patterns on Wallboard...
Sunday, September 22nd, 2002 PropertyIn many homes throughout the United States, mold spores are omnipresent, indoor temperatures range from 50º-80ºF, interior surfaces provide nutrients, and moisture is present. Figure 1 is a view of mold growth in the typical cold, damp, dark, unventilated corner of a room or closet. Most will agree that this is the usual mold growth scenario. Figure 2 shows a very fine-textured mold pattern on a ceiling in a well ventilated, bright room that appears to violate all the conditions necessary for mold growth. The ventilation and apparent lack of moisture suggest that mold growth would be unlikely in this area. A significant ingredient of what is happening here is most likely a cold spot on the ceiling as a result of a building defect or building feature.
