Health and Safety of Organic Compounds - Popcorn Ceilings 
 In the early 1930’s through the 1990’s popcorn ceilings also known as cottage cheese ceilings were found in homes commonly everywhere in the house but the bathroom and kitchen. The technique was invented by Hamilton Drywall Products to spend less time and money to create smooth ceilings. Instead of taking time to finish the ceilings properly, spraying on styrofoam, cardboard based or vermiculite materials that were often mixed with asbestos was what they did. In the late 1970’s the use of popcorn ceilings were super popular because they were known to hide imperfections and decrease noise traveling. What the contractors didn't know was the popcorn ceiling technique would be very hard to clean, difficult to repair, look outdated and the dangers of asbestos. The popcorn ceiling would also collect dust because of the rough surface, dust will attach itself to the bumps and ridges, which maintaining it was often difficult. The use of asbestos was the real problem that people didn't know. Asbestos is a mixture of silicate minerals composed of microscopic fibrils can be released into the atmosphere becoming airborne. Asbestos could cause serious chronic respiratory disease, cardiac failure, mesothelioma and cancer. Although the Clean Air Act banned spray on asbestos products in 1978 the law allowed businesses to use up the rest of their products so popcorn ceilings were still applied will into the 1980’s. The technique is still present in homes these days putting major health risk for workers removing them and people living in those homes. Not that long ago did contractors start taking their time to apply smooth ceilings this meant it was easy to clean, can be painted yourself, easier to repair, can use in bathrooms and kitchens and most importantly it didn't contain asbestos.
