Sustainability
Verifiable, not aspirational.
Mineral chemistry, low VOCs, third-party documentation per batch. We don’t hold producer certifications under our own name — our model is to source from partners who do, and to put their reports in your file with every shipment.
01 — Material
Mineral chemistry, not petrochemistry.
Slaked-lime putty, marble flour, kaolin clay, cellulose binder, natural earth pigment. Geology has tested these inputs for ten thousand years — that’s the kind of long horizon we prefer to a solvent synthesised last decade.
02 — Air
0–8 g/L VOC across the catalogue.
Per-batch ISO 11890-2 VOC test reports issued by our partner producers, supplied with every shipment. Mineral series formulations meet the emission limits referenced by California 01350, EN 16516 and the WELL Building Standard.
03 — Carbon
Lime that breathes carbon back in.
Limewash and marmorino reabsorb atmospheric CO₂ throughout their carbonation life. EPD and carbon-related figures for lime chemistries are available per project where the relevant Foshan producer or raw-material file supports disclosure.
04 — Lifecycle
Designed to last, easy to refresh.
Mineral coatings do not delaminate. After a decade, refresh with one coat of compatible finish — no sanding, no toxic stripper, no demolition waste. The wall keeps its history.
Documentation kit
What ships with every project order — and where each document comes from.
The specifier kit (PDF + DOCX) is delivered within 48 hours of order confirmation, branded for your project where contractually permitted. Each document is labelled with its issuer so your green-build consultant can verify upstream.
Per-batch VOC report (ISO 11890-2)
Issued by the producer of the batch you receive. Ships with every container.

How we phrase it
We don’t hold these certifications under our own name. We source from producers who do, and we put their reports in your file.
That’s a deliberate choice. As a sourcing & project services partner we don’t want to claim a producer’s ISO 14001 certificate as our own — that would be misleading. What we promise is that every project ships with the right document traceable to its real source, attached to your shipment.
