Natural Wall Paints
Healthy rooms start with honest materials – clay, limewash and casein instead of chemicals.
Clay, Limewash & Casein
Clay Paints
The all-rounderAt its simplest, clay paint is finely sieved clay mixed with a binder. Add pigments and natural additives and you can tailor it to almost any room. It regulates humidity, absorbs odours and creates an indoor climate you can genuinely feel – especially in bedrooms and children's rooms, where it really comes into its own.
Limewash
Tried and tested for centuriesLime is a natural disinfectant – it inhibits mould and lasts remarkably well. Houses across the Mediterranean have been painted with it for centuries, inside and out. For wet rooms, basements or listed buildings, limewash is often the smartest choice you can make. And that characteristic, slightly uneven finish? That's not a flaw – it's the best part.
Casein Paints
The quiet achieverMade from milk protein, casein paints produce velvety, slightly matte surfaces with a richness that synthetic paints simply can't match. They bond exceptionally well – even to wood – and are both water-resistant and hard-wearing.
Casein works as a full-coverage paint or as a transparent glaze. Used as a glaze, it protects the surface underneath while letting the natural texture show through – perfect for clay and lime plasters where you want the character of the material to remain visible.

Works on almost anything – when done right
Natural wall paints pair best with clay and lime plasters, but they also work well on plasterboard, concrete and masonry. The key is getting the surface right: it needs to be clean, dry and absorbent.
