when was asbestos stopped being used in popcorn ceilings?
1978
many buildings contain asbestos, which was used in spray-applied flame retardant, thermal system insulation, and in a variety of other materials. asbestos was sometimes "flocked" above false ceilings, inside technical ducts, and in many other small spaces where firefighters would have difficulty gaining access. structural components like asbestos panels were also used. in residences, asbestos was often a component of a type of flocked acoustic ceiling called popcorn ceiling or "cottage cheese ceiling", until its production was banned in the us in 1978. however, the ban allowed installers to use up remaining stocks, so houses built as late as 1986 could still have asbestos in their acoustic ceilings. the only way to be sure is to remove a sample and have it tested by a competent laboratory.

in early formulations, it often contained white asbestos fibers. when asbestos was banned in ceiling treatments by the clean air act in the united states, 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.
