Technology Demonstration of Membrane Chemical Strippers for Removal of Lead-Based Paint on Plaster

摘要

Membrane chemical strippers for removal of lead based paint were researched. The technology demonstration of the membrane chemical stripper for removal of lead based paint on plaster and assessment was conducted at an abandoned house that is now classified as a historic building at Fort Riley, Kansas in October 2002. Membrane chemical stripping was found to be generally effective at removing paint and reducing or eliminating the lead hazard. However, for plaster surfaces removal of residual paint and lead contamination must be accomplished by additional stripper applications or by HEPA sanding. Compared to other suitable methods of onsite paint removal such as low temperature heat gun paint removal, the membrane chemical stripping is relatively inexpensive. When compared with other lead paint management approaches such as enclosure, the method is expensive. The estimated cost range for membrane chemical stripping is $2.97/ft2 to $4. 74/ft2.
