They’re both intended to beautify our homes, but interior and exterior paints are not interchangeable. Here’s why.
House painting, in the broadest sense of the term, has been a practice for tens of thousands of years. The world’s oldest cave paintings date back more than 40,000 years to the Ice Age (Upper Paleolithic).
Prehistoric humans weren’t choosing between satin or eggshell finish, but the practice of adorning their interiors surely involved aesthetic decisions. Etruscans, Romans, Egyptians and other cultures throughout ancient history decorated their homes, temples and tombs with paint.
The first guilds of house painters emerged in Europe during the Middle Ages. But for the masses, house paint, especially exterior house paint, didn’t really hit the mainstream until 1866, when Sherwin, Williams & Co. (now known as Sherwin-Williams) introduced the first commercially produced paint. They soon had competition from Benjamin Moore.
