As a Council-certified Indoor Environmental Consultant, I don't generally recommend a biocide application on mold claims outside of source removal. Biocide usage can be negatively affected by time, pH, temperature, the nature of the organism you're trying to "treat", and the concentration of the biocide you use. The biocide can range from low to high toxicity to humans; may be inactivated by organic material; have a limited efficacy against a broad range of microbes; may not be EPA registered for the application you want to use it; left-over organics may be a nutrient source; not to mention the fact that re-emissions (aldehydes & chlorine) can be harmful, and the biocide you use may react with or damage some building materials. Just to give you some examples: pH has a strong influence on chlorine. Chlorine can be effective on the acid side, but not on the alkaline side. The surrounding environment can neutralize chlorine too. A finaly example: Penicillium are known to accumulate copper and can be resistant to copper containing antimicrobials. So, if you use the product wrong, you may find yourself only making the situation worse. If you need any help finding a professional in your area that does inspections for the purpose of analytical reports WITH protocol, let me know. There are some good websites out there (the best of which I've linked from my website - http://www.SolutionsIEC.com).
Best wishes.
