This product was designed so that Chinese drywall may be easily identified by the home owner. The test kit consists of 10 copper coupons for placement throughout the home over a period of 30 days. Easy to use, the copper coupons may be returned to the lab for comparison to coupons that have been corroded by known Chinese drywall reference materials at no additional charge. The identification of corrosion, utilizing this at home method, may serve as evidence in identifying Chinese drywall as laid out by the Consumer Product Safety Commission in their 2010 publication Interim Guidance- Identification of Homes with Corrosion from Problem Drywall.
