In the past, people used to whitewash the interior walls of their homes every summer: the forgotten reason resurfaces in 2026

Traditional Mediterranean limewashing is getting fresh attention. It reflects part of the heat while letting walls breathe, helping cool interiors.

The method also helps limit moisture, mold, and bacteria, which is why it was widely used every summer for centuries.

After World War II it was largely replaced by synthetic paints, but extreme heat and demand for natural materials are driving a comeback.

It is now seen as a practical passive solution for housing, restoration, and sustainable design that can reduce energy use.
