Popcorn ceilings have nothing to do with popcorns, other than the fact that they have a texture which looks like popcorns stuck on the ceiling. Also known as acoustic ceilings, they are a feature of almost all buildings, built in the 70s or 80s. They were a result of cost cutting techniques, used by builders of those times. With this ceiling, they saved the smoothing cost. Fortunately, these ceilings also turned out to be a hit with buyers. Painted popcorn ceilings look great if painted in a typical way with the right color combinations.
