Limewash

Limewash is a traditional wall finish made from crushed limestone that is burned, slaked with water, and aged into a mineral paint.

It has been used for centuries in architecture and interior design because it creates a soft, matte, and natural textured finish while allowing walls to remain breathable. Unlike modern synthetic paints, limewash bonds with surfaces through a natural chemical process, becoming part of the wall over time.
