when did they ban asbestos in popcorn ceilings
Popcorn ceiling In early formulations it often contained white asbestos fibers. When asbestos was banned in ceiling treatments by the Clean Air Act of 1978 in the United States,[1] popcorn ceilings fell out of favor in much of the country. However, in order to minimize economic hardship to suppliers and installers, existing inventories of asbestos-bearing texturing materials were exempt from the ban, so it is possible to find asbestos in popcorn ceilings that were applied through the 1980s. After the ban, popcorn ceiling materials were created using a paper-based or Styrofoam product to create the texture, rather than asbestos. Textured ceilings remain common in residential construction in the United States.
