Farmers painted their farmhouses and barns red because another paint was expensive
As you probably know, many farmhouses and barns are painted red because farmers found a cheap and natural alternative to red paint – thus, real paint was very expensive.
“Farmers didn’t have a lot of money to buy paint, and so they started to experiment with what they had on hand: skimmed milk, lime, and red iron oxide—also known as rust,” explains Jon Beer, a contractor specializing in historic restorations and owner of Jon Beer Contracting in Newburgh, New York.
These materials offered a protective red coating for wood, and today, many farmers choose to paint their farmhouses and brans red to honor this popular tradition. So, not only is this a tradition, but red paint looks really great on farmhouses.
