How to fix bad ceiling spots with popcorn mix using brush.
A popcorn ceiling, also known as cottage cheese ceiling or more accurately a Stucco 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, noise reduction qualities and ability to hide imperfections, while kitchen and living rooms ceilings would normally be finished in smoother skip-trowel or orange peel texture for their higher durability and ease of cleaning.
