Our Story
Earthaus is the latest chapter our founder Ryan Chivers’ decades-long pursuit to create the lime plaster systems he always wished existed—high-performance, thoughtfully formulated, and made with U.S.-sourced ingredients. As a lifelong plasterer and self-proclaimed materials geek, Ryan poured years of hands-on experience into every Earthaus Finish. Our plasters are not just products; they’re the result of a career spent studying the alchemy of lime, driven by a commitment to craftsmanship, beauty, and performance. The Earthaus line represents more than a business—it’s the culmination of a calling.
2001
Drawn to the world of natural building, Ryan found his footing working for a strawbale construction company in his early 20s. It was there that he first encountered lime and clay plasters—and quickly became captivated by their beauty, versatility, and environmental integrity. That spark led him to launch his own company, Artesano Plaster. Within a few short years, Ryan had earned a reputation as a go-to expert in lime, clay, and gypsum-based finishes, known for his technical knowledge and refined eye.
2005
As his expertise in traditional plasters deepened, Ryan became captivated by Tadelakt—the centuries-old Moroccan lime plaster known for its rich, polished finish and water resistance. Determined to learn from the source, he traveled to Morocco to study the craft firsthand. Returning home inspired, he began developing his own formulations, blending ancient techniques with modern insight. At a time when most plaster materials were imported, Ryan challenged the norm—believing that truly sustainable plaster should be sourced as locally as possible. This commitment to eco-friendly, U.S.-sourced ingredients became a driving force in his work.
2010
After years of hands-on refinement, Ryan began sharing his knowledge—teaching others how to blend and apply lime plaster using locally-sourced materials. He traveled across the U.S. and internationally, always championing the importance of using what’s available regionally to reduce environmental impact and strengthen local supply chains. Even as he taught, Ryan remained a student—constantly exploring new raw materials and evolving his formulas to reflect what he was learning on the ground.
2015
Ryan’s deep formulation expertise led to a key collaboration with a manufacturing partner and the launch of Limestrong Artisan Plaster—a new company and product line made entirely with U.S.-sourced materials and engineered for maximum eco-performance. This marked a pivotal step: bringing artisan-grade lime plaster to a broader market while staying rooted in sustainability and material integrity.
2020
During the pandemic, as more people turned inward and invested in creating calm, beautiful, and healthy living spaces, Limestrong gained traction. Homeowners and designers alike began seeking natural materials that nurtured well-being—and the timeless beauty of lime plaster and limewash resonated deeply. Social media played a powerful role in amplifying the look and feel of these finishes, helping them move from niche to mainstream. In the midst of global uncertainty, Limestrong became a trusted voice for healthy, eco-conscious plaster finishes rooted in craft and care.
2022
The growing demand for our products quickly outpaced the systems we had in place. It became clear that to support our customers and stay true to our values, we needed to evolve. After a year of growing pains and deep restructuring, we rebranded as Earthaus Plaster. While our formulas remained unchanged—rooted in the same integrity and performance—everything else was rebuilt: new name, new website, and a renewed commitment to serving both professionals and homeowners with clarity, care, and excellence.
2025
On Earth Day 2025, we'll launch Earthaus BUILD—a new line of plasters designed specifically for bio-based and earthen construction, including hempcrete, adobe, and strawbale. BUILD represents a natural evolution of our mission: to support healthier buildings from the ground up with high-performance, U.S.-sourced lime systems tailored to natural materials. With this expansion, Earthaus has grown beyond just beautiful finishes—we’re now offering full-system solutions for the next generation of sustainable building. It’s a bold step forward rooted in everything we’ve always believed: that lime plaster should perform, breathe, and belong.
