When creating our home, it was important for us to use natural materials that support a healthy indoor climate. That’s why we chose UKU’s natural finishes for all our walls and ceilings. We’re truly happy with the result – the surfaces feel alive, bringing warmth and character into every room. Unlike plain white walls, these finishes add depth, texture, and a welcoming atmosphere. Thank you to the UKU team for making it possible!

It’s always been a pleasure to support a local manufacturer and to introduce clay plasters during workshops for self-builders and architects. The mixes have been consistent and reliable — no surprises. I’ll continue sharing both great materials and an environmentally conscious mindset in the future!

I loved painting with UKU clay paints! The shades are beautifully soft, and the surface has a lively, pleasant texture. Another big plus was how easy it was to mix the paint and clean the tools using only water.

✨ Client Story: Natural Warmth at Home ✨

“When creating our home, it was essential for us to use natural materials that support a healthy indoor climate. That’s why we chose UKU’s natural finishing materials for all walls and ceilings throughout our living spaces.

We’re genuinely happy with the result – the finished surfaces feel alive and bring a warm, inviting atmosphere into every room. While plain white walls can sometimes feel cold or impersonal, in our home the walls have become a key part of the interior – adding depth, texture, and character.”

– Anu Reinson, Interior Stylist & Photographer
