How cow dung was used as a fixative in some traditional mural paintings?
August 1, 2026 · 6 min read · by Walensky
Picture an artisan from Rajasthan, crouched at dawn in front of a wall still wet with dew, blending mineral pigments with almost ritual precision into a substance that nature offers him effortlessly every morning. That substance? Fresh cow dung. Behind this age-old gesture lies a fascinating alchemy, a material wisdom that our contemporary interiors have entirely forgotten, and that deserves to be rediscovered.
Here is what the use of cow dung as a fixative in traditional mural paintings offers us: a deep understanding of the link between living matter and lasting color, a fascinating reinterpretation of ancestral decorative techniques, and an endless source of inspiration for lovers of authentic, natural decoration.
Did you think traditional mural paintings were simply a matter of applying pigments to a wall? It is far more dizzying than that. And if this truth unsettles you slightly, good news: it also proves that the great decorative civilizations feared nothing in their pursuit of beauty.
When nature becomes the binder: the well-kept secret of ancestral murals
Traditional mural painting has never been a matter of synthetic tubes and brushes. For millennia, artisans around the world studied their immediate surroundings to find binders capable of fixing natural pigments onto surfaces. Cow dung, rich in partially digested plant fibers, microorganisms and complex organic compounds, became one of the most effective binders in the history of mural paintings.
In India, West Africa, pre-Columbian Mexico or certain Mediterranean regions, traditional mural painting systematically incorporated organic materials as binders. Cow dung held a place of honor there, not for lack of alternatives, but because its properties were irreplaceable.
The chemistry of living matter in the service of color
Why did cow dung work so well in mural paintings ? The answer is as chemical as it is practical. Dung contains a high concentration of partially degraded cellulose, lignin, urea and mineral salts. As it dries, these compounds create a fibrous matrix that literally traps the pigments within the wall.
In practice, artisans mixed fresh dung with clay, lime or plaster to prepare a base coat. This mixture, applied in successive layers, gave traditional mural paintings a slightly rough, almost velvety texture that held pigments with remarkable efficiency. The plant fibers in the dung played a role similar to glass fibers in our modern materials: they mechanically reinforced the painted surface.
An unsuspected natural antibacterial
What artisans knew intuitively, and science confirmed much later, is that cow dung possesses natural antibacterial and fungicidal properties. In tropical or humid contexts, mural paintings made with this binder resisted mold and biological attack better than those prepared without it. Houses in Rajasthan, whose walls were coated with a mixture of clay and dung, enjoyed a healthier indoor microclimate — a performance modern wall paints attempt to reproduce with chemical additives.

In India, the practice has been codified for centuries. Village women in Bihar, Rajasthan or Gujarat applied a fresh coat of diluted cow dung each morning to the floors and walls of their homes. This ritual, called lepai, often preceded the creation of traditional mural paintings such as Madhubani or Warli art.
Dung served both as surface preparation and as the first binder. It evened out the surface, filled hairline cracks in the clay, and created a slightly alkaline base that stabilized natural pigments — ochres, indigos, vermilions — for decades. Some mural paintings in rural Indian temples, made over a century ago using these methods, still display colors of unsettling vividness.
From Africa to the Andes: a universal decorative wisdom
The tradition does not stop at India's borders. In West Africa, notably among the Kassena peoples of Ghana and Burkina Faso, the geometric mural paintings adorning house facades are made on renders where cow dung plays a major structural role. Mixed with laterite and water, it forms a natural waterproofing coat on which artisans apply white pigments based on kaolin.
These African traditional mural paintings, with their zigzag motifs and contrasting flat areas, have endured for centuries thanks to this organic binder. Dung also improved adhesion on banco supports — that mixture of raw earth and straw that forms the bulk of Sahelian vernacular architecture. Beyond the building, an entire aesthetic perpetuates itself: that of a living mural art, renewed every dry season.
The symbolic dimension of the fixative
In many cultures, cow dung was not merely a technical material. It carried powerful symbolic weight: purifying in Hindu tradition, protective in African animist beliefs, it transformed the act of painting a wall into a ritual of care and protection for the home. Traditional mural paintings were not mere decorations — they were acts of life, gestures charged with intention.

What these murals tell us about our relationship with matter
Rediscovering the role of cow dung in traditional mural paintings means reconciling ourselves with a certain intelligence of the living world. Our ancestors did not settle for whatever lay at hand by default — they worked with an empirical precision that centuries of observation had refined. Dung was not a makeshift: it was the optimal solution within a given ecosystem.
Today, as natural decoration and bio-sourced materials experience a spectacular revival, these ancestral mural paintings resonate like a manifesto. Lime renders, casein washes, raw mineral pigments — everything returning to favor in high-end contemporary interiors — belongs to the same philosophy as these dung-coated walls: raw material, well understood, creates the greatest durability.
These traditional mural paintings also remind us that decoration has always been a dialogue between humans and their territory. Using cow dung as a binder meant encoding into the very walls of the house the agricultural landscape surrounding it. A form of radical and poetic decorative localism.
Traditional mural painting as a source of contemporary inspiration
For lovers of authentic decoration, these ancestral mural paintings open dizzying perspectives. They show that a painted surface can be far more than a layer of color: it can be a narrative, a territory, a spiritual practice. They also show that the most durable traditional mural paintings are those that embrace their environment rather than oppose it.
Drawing on these traditions to decorate a contemporary interior means choosing mural artworks that carry the same depth — pieces that tell a story of material, territory and gesture. Paintings drawn from African artistic traditions, for example, inherit directly from these cultures of the living wall, the organic support, the natural pigment rooted in the earth.
The next time you admire a wall in warm, earthy colors in a well-appointed interior, remember: somewhere in the history of that color, there may be a herd of cows, a woman crouched at dawn, and the quiet certainty that beauty always arises from what nature offers in abundance.
Frequently asked questions
Why did cow dung fix pigments onto a wall?
As it dries, the partially degraded cellulose, lignin, urea and mineral salts it contains form a fibrous matrix that traps the pigments within the wall. The plant fibers mechanically reinforce the painted surface, somewhat like glass fibers in modern materials.
What was dung mixed with to coat a wall?
Artisans mixed fresh dung with clay, lime or plaster to prepare a base coat. Applied in successive layers, this mixture gave a slightly rough, almost velvety texture that held the pigments with remarkable efficiency.
What role did dung play in madhubani and warli paintings?
In the villages of Bihar, Rajasthan and Gujarat, a fresh coat of diluted dung was applied each morning to floors and walls. It evened out the surface, filled the microcracks in the clay, and created a slightly alkaline base that stabilized the natural pigments.
Did cow dung protect walls from humidity?
It possesses natural antibacterial and antifungal properties: in tropical or humid contexts, paintings resisted mold better. In West Africa, mixed with laterite, it even formed a waterproofing coating that adhered well to banco, the raw earth mixed with straw.
