Popcorn ceiling

A popcorn ceiling (slang), also known as cottage cheese ceiling or Stucco ceiling or more accurately an Acoustic ceiling, is a term for a spray-on or paint-on ceiling treatment used from the late 1950s into the 1980s in American residential construction. It was the standard for bedroom and residential hallway ceilings for its bright, white appearance, ability to hide imperfections, and acoustical characteristics. In comparison, kitchen and living room ceilings would normally be finished in smoother skip-trowel or orange peel texture for their higher durability and ease of cleaning.
