In 2025, natural finishes are no longer a niche choice. They have become a central part of how architects and designers shape healthy, timeless, and emotionally resonant interiors.

Among them, limewash, roman clay, and tadelakt stand out as three techniques that embody the values of sustainability, craftsmanship, and well- being.

Why are they making a comeback?

Biophilic connection: Natural mineral surfaces soften the atmosphere of a room, absorbing light instead of reflecting it harshly. This quality aligns perfectly with biophilic design, which is now at the core of wellness-driven interiors across Europe.

Texture and depth: The cloudy transitions of limewash, the velvety matte of roman clay, and the silky sheen of tadelakt create surfaces that evolve throughout the day, catching light in ways synthetic paints never could.

Durability with beauty: Particularly in wet rooms, tadelakt offers seamless, water- resistant surfaces that can last for decades when applied with care.

Material snapshot:

Limewash: A mineral-based, breathable finish that brings soft, cloud-like tonal variation to walls. Popular in warm neutral and earth palettes, it allows walls to age gracefully.

Roman clay (clay plaster): Smooth, satin-matte, VOC-free, and highly tactile. Its natural texture is ideal for projects where the wall itself becomes a design feature.

Tadelakt: An ancient Moroccan lime plaster polished with olive soap, achieving a waterproof, marble-like surface. Its seamless continuity creates sculptural, calming spaces in bathrooms and spas.

Color and composition

Current European trade fairs show a clear direction: earth-derived tones, tactile finishes, and the celebration of imperfection. Limewash in warm beiges, clays, and terracotta hues pairs beautifully with handcrafted ceramics. Roman clay provides the soft backdrop that allows natural stone or wood to stand out. Tadelakt, in its subtle gloss, adds depth and elegance to intimate spaces.

Application tips

Always test samples: Light conditions change the perception of texture and tone. Large sample boards on site are essential. Layer patiently: With lime and clay finishes, proper curing between coats makes all the difference in the final appearance. Rely on skilled hands: Especially for tadelakt, experienced craftsmanship is key to unlocking both beauty and performance. Think long term: Sustainability means making choices that prolong a surface’s life, instead of simply relying on “natural” materials.
