Why Are Barns Almost Always Painted Red?

Introduction

The question of why barns are almost always painted red is a fascinating one, with numerous theories attempting to explain the phenomenon. Let's delve into the history and practical reasons behind the popularity of this color.

Theories Behind the Red Color

Several theories exist regarding the origin of the red color for barns. One popular theory suggests that red paint was used because it helped in masking the telltale signs of blood from animal slaughter, which was often added to linseed oil to protect the wood from decay and weathering. The addition of rust, another theory proposes, provided additional preservative qualities, as rust is known to be a natural preservative.

Yet another theory posits that the red color was imitative of the appearance of brick, a material that was only affordable to the wealthy. As paints became commercially available, red remained a popular choice due to its affordability, and farmers chose it over other colors.

Rust and Preservation

Centuries ago, before the advent of modern paints, barns were sealed with linseed oil, which is an orangey-red oil derived from the seeds of the flax plant. Since rust was readily available on most farms, it was often added to the oil to provide preservative qualities. Rust is a natural preservative that is both antifungal and antimicrobial. This combination made the final color a dull rust red, which was ideal for protecting and preserving the wood.

Some barns and fences were also painted using whitewash, a mixture of milk and powdered limestone. Whitewash was cheap, easy to apply, and could be easily repainted to maintain a clean look. Furthermore, it helped prevent fungal growth, which is why Tom Sawyer tried to pawn off the chore of whitewashing fences on others!

Vegetable-Based and Motor Oil Stains

Before modern paints became available, farmers turned to more natural materials. For instance, staining barns with used motor oil was a common practice. The metal fragments in the oil would rust over time, turning the wood orange and providing protection. This technique was not only cost-effective but also environmentally friendly, as it utilized waste oil. My father stained our backyard fence with used motor oil 30 years ago, and it still stands strong, showing no signs of rotting.

Similarly, some barns might appear brown or orange due to the use of natural materials and the effects of rust over time. Staining wood with used motor oil was a practical and effective method of preserving wood, as the metal fragments in the oil would create a protective coating, aiding in the prevention of decay.

Conclusion

The color red has become synonymous with barns, rooted in practicality and tradition. From the use of linseed oil and rust to the application of natural and protective materials, the tradition of painting barns red continues to this day. Whether due to practicality, resourcefulness, or a mix of both, the red color has become a deeply ingrained part of barn culture.
