A localized collaboration with @brukspecialisten — Reclay is here. 🌱
It’s always been our core vision: creating truly localized natural materials tailored to each region. Sweden has raw clay in the ground, but what it needed was proper local clay plaster.
Teaming up with our partners @brukspecialisten, we set out to make it happen. After months of development, testing fractions (0–4 base to 0–1 fine) and perfecting the mix, we finally nailed it.
Meet Reclay, authentic brown Swedish clay plaster, bagged up at the factory and ready to roll.

Local materials, raw beauty. 🌿
At UKU, localization is at the heart of everything we do. Together with our Swedish partner and distributor @brukspecialisten , we developed a custom Marmorino finish crafted from authentic Swedish blue clay, enriched with charcoal for a richer, darker tone and an organic depth. True elegance comes straight from the earth.
