Asbestos in Popcorn Ceiling - Popcorn Ceiling With 2 to 3 Percent Asbestos - asktooltalk.com
Even though the use of asbestos in the popcorn mixture was banned in 1978, many popcorn ceilings installed before the 1980s contain up to 8 percent asbestos, and it has been found in ceilings installed as late as 1986.
Intact and undisturbed, popcorn ceilings pose no health risk, but when asbestos-containing material deteriorates or is damaged or disturbed, its minuscule fibers become airborne. Even roller painting the ceiling may disturb fibers or weigh down the popcorn, which may cause it to delaminate from the substrate. Once the fibers are airborne, it takes careful cleaning with appropriate equipment to decontaminate a home.------------------------------------------- posted 6:27 AM :: reference link ::
