Popcorn ceilings can be sprayed on to add texture.
Popcorn ceilings came into use in the 1950s. A textured finish that is sprayed on, the material offers some soundproofing benefits. Common reasons for use include the ease of application and ability to cover cracked or uneven ceilings. The mixture contains clays, cellulose, adhesive, polystyrene and ethyl vinyl acetate. Older ceilings may

Polystyrene
Polystyrene is a common plastic used in many everyday products. It gives popcorn ceilings texture and is the main ingredient of Styrofoam. Foam packaging and insulation contain polystyrene. It is an inexpensive and hard plastic which lends itself well to uses including the housing of computers. Adhesive, clay and ethyl vinyl acetate also make up popcorn ceiling texture.

It is a messy job, however. It will require plastic to protect floors and walls. One of the best ways to get it down is to get it thoroughly wet and then scrape it off. Wear a dust mask as even without asbestos you do not want to breathe any dust in. If the ceiling
