Popcorn Texture

Popcorn Texture, also known as Popcorn Ceiling texture, is the product that was spray-applied to drywall ceilings until around 2002. **Caution** In homes built up to 1978-1980, the product contained asbestos. Never scrape in an older home unless you get it tested first. Best to drywall over in older homes. Source: Jason Lebeau a 24-year drywall industry veteran.

Popcorn texture, also called "cottage cheese" or "acoustic" ceiling, is a bumpy, sprayed-on finish for walls/ceilings made of joint compound mixed with Styrofoam or vermiculite particles, creating a rough, sound-dampening surface popular from the 1950s to the 1980s for hiding drywall imperfections cost-effectively. It offers sound absorption and quick application, but can be hard to clean and may contain hazardous asbestos in older applications, requiring professional testing.
