CLOUDLIME
Purest Form of Mineral Limewash, Built for Healthy Living.
Free from synthetic resins and hidden chemical additives, Cloudlime is a rigorous two-step system. By pairing our 100% VOC-free organic Casein Primer with pure mineral limewash, we achieve an uncompromising balance of timeless architectural beauty and absolute indoor environmental health.
The Two-Step System Stack
Step 1: The Organic Casein Primer
Engineered for Environmental Health: Specifically developed for individuals with chemical sensitivities, VOC hypersensitivity, and a strict commitment to pristine indoor air quality.
Lab-Certified Purity: Backed by independent laboratory certification, both our Casein Primer and Cloudlime finish are verified 100% VOC-free, containing zero trace chemical residues.
The Reality of Material Integrity: Casein-based primers demand meticulous application technique and strict environmental control. While it would be commercially convenient to introduce synthetic resins or acrylic modifiers for effortless application, true material purity and indoor health do not allow for such shortcuts. Achieving an organic, toxin-free wall requires specialized skill rather than chemical compromise.
Uncompromising Breathability: Unlike standard commercial acrylic or PVA primers that seal walls shut like a plastic bag—trapping moisture and causing eventual paint failure—our organic casein binder anchors securely to porous masonry while maintaining complete vapor permeability.
Step 2: Cloudlime Mineral Finish
The Science of Carbonation: Unlike modern plastic emulsions that dry purely via evaporation, Cloudlime undergoes a natural chemical process of carbonation, crystallizing into microscopic calcite. It effectively reverts to stone on your wall, delivering unmatched organic depth and a soft-focus cloud effect that evolves with changing daylight.
Why Traditional Mineral Chemistry Outperforms Modern Paints
Living Minerals & Natural Light Refraction
Limewash cures through carbonation into a micro-thin layer of natural stone. When light strikes these micro-crystalline facets, it refracts deep within the mineral layer rather than bouncing off the surface—producing a signature, soft-focus cloud effect and a natural, shifting glow.
Hypoallergenic & Mold-Inhibiting pH
Curing at a naturally high alkaline pH (12 to 13), Cloudlime creates an inhospitable environment for mold, mildew, and bacteria. It neutralizes indoor allergens purely through mineral chemistry, offering complete protection without synthetic fungicides or toxic chemical off-gassing.
100% Biodegradable & Circular Mineral
Formulated exclusively from pure earth minerals and slaked lime, Cloudlime contains zero synthetic resins, acrylic binders, or chemical additives. At the end of its lifecycle, it breaks down cleanly into basic mineral components without leaving microplastics or toxic residues behind.
Earth-Forged Pigments
Tinted entirely with natural rock, clay, and iron oxide minerals, these earth-forged colors integrate directly into the slaked lime structure rather than sitting flat on top. The result is an enduring, authentic patina that will never fade, off-gas, or lose its organic depth.
