The global earthen plasters market was valued at USD 84.2 billion in 2024 and is expected to reach USD 109.7 billion by 2030, growing at a compound annual growth rate (CAGR) of 4.5% between 2025 and 2030. This growth is fueled by a combination of environmental, economic, and cultural factors driving the increasing demand for sustainable construction materials.

The expansion of construction activities worldwide, especially in residential and commercial sectors, is a major factor boosting the need for earthen plasters. With rapid urbanization, sustainable building practices are gaining traction, positioning earthen plasters as an eco-friendly choice for both interior and exterior finishes. Additionally, a renewed interest in traditional and natural building methods is contributing to the market’s growth. Used for centuries in various cultures, earthen plasters are experiencing a resurgence as part of a broader movement to preserve craftsmanship and utilize locally sourced materials. This cultural revival, coupled with modern sustainability goals, is increasing their popularity in contemporary construction projects.

One of the primary drivers behind this market is the environmental advantages of earthen plasters. Made from natural ingredients such as clay, sand, and natural pigments, these plasters are non-toxic and free from volatile organic compounds (VOCs), promoting healthier indoor air quality. Their natural composition also provides thermal insulation benefits, improving building energy efficiency. Moreover, earthen plasters are biodegradable and have a lower environmental footprint compared to synthetic alternatives, making them a preferred option for eco-conscious builders.
