Our Materials
Every Earthaus finish begins with raw ingredients sourced from nature: lime from ancient shells, pumice from ancient volcanos, and mineral pigments from the earth, and aggregates chosen for performance and purity. Designed for human health, crafted for sensory beauty, and rooted in principles of regeneration, our materials bring integrity to the mineral finishes that surround you.
Natural - Healthy - Biophilic - Regenerative
Natural
Our mineral finishes are formulated with time-tested materials — lime, pumice, and mineral pigments — all derived from simple, raw, natural sources. Lime is refined from limestone: formed from ancient coral and fossilized seashells once part of primordial oceans, now reborn as breathable finishes for modern spaces. Pumice is an exceptionally light, porous volcanic stone—lava frothed by escaping gases and rapidly cooled. When added to lime plaster, it acts as a pozzolan—enhancing strength and durability in our finishes. We source all of our materials in the U.S. from trusted quarries and suppliers who share our commitment to purity, responsibility, and integrity.
Healthy
In a world full of hidden toxins, your walls should never be one of them. Our mineral finishes are crafted to support a healthy environment — free from VOCs, petrochemicals, and harmful additives that compromise indoor air or long-term safety. Safe for all living beings, our materials are made to protect what matters most: you and your family’s health.
Biophilic
Nature heals — and choosing biophilic materials in our homes is the bridge that reconnects us to it. Our plasters support well-being and sensory restoration through organic textures, mineral pigment hues, and raw, natural beauty. With soft variation, quiet depth, and a subtle interplay of light, Earthaus lime finishes embody biophilia and bring a grounded sense of calm and connection into the built environment.
Regenerative
Our mineral finishes are regenerative — meaning they don’t just minimize harm, they actively restore, renew, and strengthen the holistic systems they’re part of. Our lime plasters are sustainably sourced, intentionally designed and packaged to reduce our carbon footprint, and made with natural safe ingredients that do no harm once installed. Our products create durable, breathable systems for natural building assemblies, sequester carbon as they cure, and safely biodegrade at the end of their life. By using regenerative materials and designing regerative products, we support healing the climate and building homes that are healthier for people and the planet — now and for generations to come.
