    The Science Of Mold Growth

    With this conflicting information, it is time for more research.

    Working in conjunction with my fellow instructors, we did a detailed scientific/technical literature review and found a peer reviewed paper entitled Controlled Study of Mold Growth and Cleaning Procedure on Treated and Untreated Wet Gypsum Wallboard in an Indoor Environment, by Michael Krause, CIH, with Veritox Inc.

    Krause and his associates performed basically the same test that we did, except they did it with a number of untreated and treated wallboard sheets under very controlled scientific conditions.

    According to Krause, it took at least a week to confirm that invisible microscopic growth structures had formed on wet untreated wallboard in a closed office.

    Mold growth colonies were not visible on untreated drywall until three weeks into their eight week experiment.

    The first mold types seen were Acremonium, Penicillium and Cladosporium. Stachybotrys was never seen. Visible mold did not grow on wallboard that was coated with a primer.

    Additionally, a study done by Dr. Michael Berry, prepared for the Carpet and Rug Institute , showed that drywall and framing lumber, when exposed to a controlled environment with a temperature of 80 degrees Fahrenheit and a relative humidity of 80 percent, did not display visible mold until week five .

    A listing of a few of these papers is at the end of this article.
