Come and create a sustainable and healthy living environment with us

Saviukumaja is located in the legendary Mooste manor in picturesque Southern Estonia, where we produce world-class finishing mixes and paints under the brand name "UKU Pure Earth".

UKU – Pure Earth is the oldest producers of clay and lime natural finishing materials in Scandinavia and the Baltic region with roots dating back three generations.
We have several generations of experience in the installation of clay and lime plasters, and thanks to this we know exactly what characteristics a high-quality finish must have.
Through the last twenty years of experimentation, we have achieved great craftsmanship to create perfect natural finishing materials.

UKU clay base plaster quality comes from the German quality standard (DIN 18947: 2013) and accordingly qualifies for the highest strength class S ll.
Our lime plasters have also been tested according to EN 998-1.

We use natural and 100% pure raw materials in production.
UKU products are free of toxic substances and volatile organic compounds, which ensures clean air quality in the room and a healthy living environment.
All our mixes are compostable, recyclable and do not pose a threat to the environment.
We use solar energy for production, which makes the energy spent by us on the production of materials practically non-existent when compared to the production of finishing materials based on cement and gypsum.

We do our best to ensure a more sustainable living environment on planet Earth.
