Sustainability is central to how Earthaus operates and makes products. The Earthaus mission is "Plaster Naturally. Build Regeneratively." — a commitment to showing that construction materials can be both regenerative and timeless, that they can serve the health of humanity and help restore the planet, all while elevating design. Read the full story on Our Ethos.
Regenerative Building & Innovation
Earthaus 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.
Through Earthaus BUILD, Earthaus supports the next generation of carbon-capturing architecture — bio-based systems like straw bale and hempcrete. These natural building methods lock in atmospheric carbon, and Earthaus plasters protect them, allow them to breathe, and enhance their long-term performance.
Ingredient Transparency & Healthy Materials
Conventional construction materials often contain toxins that compromise indoor air quality and human health. Earthaus uses only pure, natural materials — free from harmful additives — to reduce this toxic burden and create safer spaces.
Earthaus products are always free of:
VOCs, formaldehyde, microplastics, phthalates, or toxic additives
PFAS chemicals, endocrine disruptors, obesogens, or asthmagens
Petrochemical colorants
See Healthy Product Declarations and Ingredient Transparency for details.
Sourced and Made in the United States
Earthaus plasters are sourced and made in the U.S., with 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, this key ingredient reacts with lime to improve strength, resilience, and overall performance.
Domestic sourcing eliminates the high costs of overseas imports while maintaining strict quality standards, and lightweight formulations optimize shipping efficiency — reducing transportation costs and impact without compromising durability or performance.
Craftsmanship
Earthaus is dedicated to supporting all generations of plaster artisans and celebrating the artistry of their craft — honoring the rich legacy of traditional plastering while evolving in partnership with the artisans who bring the materials to life.
Rooted in Duluth, Minnesota
Earthaus is based in Duluth, Minnesota — an environment of clean air, clean water, and the natural beauty of Lake Superior that fosters a mindful approach to design and sustainability in everything Earthaus makes.
