Cleanup involves HEPA-filtered vacuums, a total scrub-down, and disposal of the top layer of plastic sheeting, after which the space must be retested for asbestos before the job can be considered done. A new option lets you encapsulate friable asbestos with a spray-on silastic elastomer , turning it into a stable, nonfriable version, which can then be left in place.
