Our Mission
Every day, we ask ourselves: What about the health of the people living in their homes? The artisans applying architectural finishes? What about the embodied carbon of our materials, or the energy required to make and ship them? How do we make the best choice also the most beautiful one?
Each answer leads to a new question — pushing us to refine, rethink, and raise the bar.
Earthaus doesn’t exist just to make plaster. We’re here to shift the paradigm: to show that construction materials can be both regenerative and timeless, that they can serve the health of humanity, help restore the planet, all while elevating design. By combining modern building science with ancient lime traditions, we aim to set a new standard — one that’s actionable, replicable, and grounded in the living textures of the natural world.
Our Core Commitments
We are dedicated to creating innovative & regenerative plaster solutions that honor the earth, ensuring our products and business contributes to a more livable planet. We are unwaveringly transparent, using natural and non-toxic ingredients to craft finishes for truly healthy homes. Our passion for plaster craftsmanship inspires our generosity to give knowledge, celebrating the artistry and skill of natural plastering, fostering creativity and preserving time-honored techniques for generations to come.
Innovation
Our plasters are designed to do no harm — and to support regenerative architecture. Engineered for performance and longevity, Earthaus finishes contribute to a lower carbon footprint and more sustainable construction.
We’re proud to support the next generation of carbon-capturing architecture — bio-based systems like straw bale and hempcrete through Earthaus BUILD. These natural building methods lock in atmospheric carbon, and our plasters protect them, allow them to breathe, and enhance their long-term performance.
Whether for conventional or regenerative construction, each Earthaus formula reflects our commitment to innovating on behalf of the health of people and the planet.
Transparency
We are steadfast in our commitment to ingredient integrity. Conventional construction materials often contain toxins that compromise indoor air quality and human health. At Earthaus, we use only pure, natural materials — free from harmful additives — to reduce this toxic burden and create safer spaces.
Our products are always free of:
- No VOCs, formaldahyde, microplastics, phthalates, or toxic additives
- No pfas chemicals, endocrine disruptors, obesogens, or asthmagens
- No petrochemical colorants
Craftsmanship
At Earthaus, we are dedicated to supporting all generations of plaster artisans and celebrating the artistry of their craft. We honor the rich legacy of traditional plastering while evolving in partnership with the artisans who bring our materials to life. Together, we expand the reach and influence of the eco-friendly, healthy, and handcrafted beauty of plaster far and wide.
Our Products
Performance: Backed by 15 years of field testing, Earthaus Plasters are engineered for straightforward, user-friendly, and dependable application every time. Our plasters are formulated for exceptional durability and workability, optimized through carefully selected ingredients:
- Hydrated Dolomitic Lime: Sourced from the Great Lakes region, this magnesium-rich lime enhances flexibility, adhesion, and long-term strength.
- Pumice Pozzolan: Derived from volcanic materials, pozzolans have been used since ancient times to create durable, cementitious mixes. This key ingredient reacts with lime to improve strength, resilience, and overall performance.
Affordability: Our commitment to affordability ensures that high-quality, sustainable plaster solutions remain within reach. By sourcing all materials domestically, we eliminate the high costs of overseas imports while maintaining strict quality standards. Our lightweight formulations optimize shipping efficiency, reducing transportation costs without compromising durability or performance.
