Safety concerns were the primary driver behind this design trend’s fall from favor. Before the late 1970s, many popcorn ceilings used asbestos to create the bumpy texture. While asbestos is safe when it’s left undisturbed, if it becomes airborne, it can lead to cancer and other diseases.
Modern popcorn ceilings are made with materials like Styrofoam, but the negative association with asbestos remains.
Of course, it’s not just about safety. Another reason popcorn ceilings’ popularity declined is because of their aesthetic. Most people simply don’t like the look of popcorn ceilings. They also tend to collect dust and dirt, and can be difficult to clean.
