Calce cruda in Geneva: mineral paint made from raw lime, applied by hand by CFC-qualified craftsmen
Azzo Peinture has been applying calce cruda throughout the canton of Geneva since 2018. Two skilled plasterers and painters, each holding a CFC qualification and with over 25 years’ experience in the trade. A traditional Italian wall finish, applied by hand in three to four coats — for a velvety, breathable and natural finish that no standard paint can replicate.
Calce cruda is Italian raw lime, applied by hand to create a unique finish
Calce cruda — literally ‘raw lime’ in Italian — is a decorative wall finish made from unburnt lime, natural mineral pigments and water. It is applied with a stainless-steel trowel in successive thin layers, using circular movements that create a unique finish: a deep, velvety matt texture with subtle variations in shade that change with the light. A wall finished with calce cruda is unlike any other.
Why choose calce cruda for your Geneva homes
Calce cruda combines three rare qualities — an inimitable aesthetic appeal, valuable technical properties that enhance indoor comfort, and a natural composition that meets contemporary environmental standards.
- A unique aesthetic appeal : Calce cruda produces a deep, velvety matt finish that paint cannot replicate. The circular movements of the spatula application create subtle variations in shade that play with natural light — a wall that almost seems to breathe, with areas appearing lighter or deeper depending on the time of day. It is this distinctive visual quality that appeals to high-end contemporary interiors.
- A wall that breathes : Unslaked lime is a mineral material that is permeable to water vapour. It allows walls to breathe, naturally regulates indoor humidity and prevents mould and mildew from taking hold — a valuable feature in a bathroom, kitchen or bedroom. A wall finished with calce cruda actively contributes to air quality.
- A natural 100% coating : lime, mineral pigments, water. Nothing else. No solvents, no synthetic resins, no volatile organic compounds. Calce cruda is certified for use in high-energy-performance homes and eco-construction projects, without compromising indoor air quality. It is particularly recommended for children’s bedrooms and for people with sensitivities.
- Natural antibacterial properties : Lime is alkaline. This alkalinity naturally prevents the growth of bacteria, mould and dust mites on wall surfaces. This is a valuable health benefit, particularly in damp rooms and public spaces such as waiting rooms, spas and restaurants.
Where ‘calce cruda’ really comes into its own in a Geneva home
Calce cruda can be applied to the interior walls of almost any room — but there are certain settings where it really comes into its own. Here are the situations where it makes perfect sense.
- Bedrooms and master suites : the velvety finish creates a soothing, almost enveloping atmosphere. The subtle shades change with the morning and evening light. An accent wall behind the headboard in natural beige ‘calce cruda’ or terracotta is a contemporary signature feature.
- Living rooms and lounge areas : Whether used on an entire wall or as an accent, calce cruda adds depth that showcases designer furniture, works of art or a beautiful bookcase. It works just as well in minimalist contemporary interiors as it does in the renovation of old Geneva flats.
- Bathrooms and wet rooms : The breathable and antibacterial properties of raw lime make it an ideal choice for damp rooms. A bathroom entirely treated with raw lime creates a natural spa-like atmosphere, with the added benefit of humidity regulation. Please note, however, that in areas subject to direct and prolonged exposure to water (walk-in showers, around the bath), an additional protective treatment is essential.
- Entrance halls and circulation areas : Calce cruda welcomes visitors with its handcrafted, high-end finish, which is very different from standard paint. It offers good durability, even in high-traffic areas.
- Business spaces : high-end boutiques, architectural practices, restaurants, spas, hotel rooms — wherever atmosphere and image matter, calce cruda adds an instantly recognisable signature that sets the venue apart from the competition.
A step-by-step guide to applying calce cruda by hand
Calce cruda cannot be applied with a roller. Each square metre is applied by hand, using a stainless-steel trowel, in several layers. It is this artisanal technique that gives the final finish its value — but it requires a methodical approach and patience.
- Preparing the surface : The wall is carefully repaired where there are cracks, thoroughly sanded and, if necessary, given a smoothing coat. Once the surface is smooth and clean, it is treated with a primer suitable for lime. This stage is crucial for the rest of the process: on a poorly prepared surface, no amount of skilled finishing work can compensate for this.
- Choice of pigment and on-site trial : We provide a professional colour chart of the available mineral pigments — natural shades, earth tones, minerals, ranging from off-white to deep brown, including warm greys and ochres. A sample is applied to the wall to be treated and checked in the natural light of the site, both in the morning and in the evening, before any work begins.
- First coat of primer : The first coat of calce cruda is applied with a stainless-steel trowel, in a thin, even layer. It serves as a visual base and ensures good adhesion for the subsequent layers. Drying time: 12 to 24 hours, depending on the ambient humidity.
- Second and third layers — the artisanal touch : this is where the finish is achieved. Each new layer is applied using circular movements, in a random order, to create the variations in shade that form the visual signature of the calce cruda. The spatula must be handled with care — too much pressure leaves marks; too little pressure means it doesn’t catch the paint properly. Two additional layers are often sufficient; sometimes, a fourth layer is added to provide the final depth.
- Complete drying and possible protection : The wall will reach its final colour after 4 to 7 days of complete drying. On surfaces subject to heavy exposure to water (shower surrounds, washbasin tops), a protective treatment using lime wax or a compatible matt varnish is applied as the final step.
Calce cruda, stucco marmorino or polished concrete: how to choose
Three traditional techniques are often confused, even though they produce very different results. Here’s a brief overview of each to help you make your choice — we’ll then show you a sample in context.
Calce cruda: a velvety matt finish with depth
A soft, matt finish with subtle variations in shade. Ideal for contemporary interiors seeking a handcrafted look without a glossy finish. Perfect if you’re looking for «a beautiful paint with character» rather than a bold finish.
Marmorino stucco: the mineral finish that reflects light
Smoother and glossier, with a polished stone-like finish. Marmorino stucco draws inspiration from the Venetian tradition and plays with light — reflections, transparency and a marble-like effect. Ideal for a wall that needs to make a visual statement, often in a reception area or as an architectural feature wall.
Polished concrete: contemporary industrial mineral aesthetics
A harder, more contemporary finish with a mineral cement look. Polished concrete can be applied to both floors and walls, including in bathrooms where complete waterproofing is required. It is the ideal choice for an interior with an industrial design or for a bathroom with a contemporary aesthetic.

Two CFC-qualified tradespeople, each with over 25 years’ experience, providing a personalised service on every job.
Genuine artisanal skill, not a technique learnt from a video
Applying raw lime requires a delicate touch, a precise understanding of the substrate and real-world experience of the different application techniques. It is a technique that is mastered over the years — not through a few YouTube tutorials. Aureliano and Harald have applied raw lime to dozens of building sites in Geneva before offering it to their clients. Their technique is sound.
A sample that is always tested in a real-world setting before any commitment is made
Whether on a screen or in a colour chart, ‘calce cruda’ doesn’t look the same as it does on your wall. We always apply a sample in situ — on your wall, in your own lighting — and wait for your approval in both morning and evening light before starting the work. A sample costs just a few euros; a colour that’s got it wrong across an entire living room costs a great deal more.
A single point of contact from quotation to handover
Aureliano or Harald oversees every calce cruda project, from the preliminary site visit through to final handover. No subcontractors, no rotating teams. The same craftsman who approved the sample with you is the one who applies the raw lime to your walls.
A calce cruda project in Geneva – how does it actually work?
From the site visit to handover: five clear steps to ensure a well-managed project with no unpleasant surprises.
- Technical inspection and assessment of the substrates : On-site visit to Geneva, assessment of the condition of the walls, identification of the work required (cracks, old render, primer to be applied), discussion of the desired finish and presentation of the colour chart.
- Detailed estimate : surface preparation, primer, application, any necessary protection — a line-by-line quote, with transparent pricing per square metre. Calce cruda is more expensive than conventional paint — we explain this clearly so that you can make an informed decision.
- Placing a sample in situ : We apply one or two colour samples to the wall in question and await your approval, based on how the colours look in the natural light at the site, before proceeding. This step takes a few days but helps to avoid any regrets.
- Directed by Aureliano or Harald : Careful preparation of the surfaces, application of a suitable primer, followed by three to four coats of calce cruda applied using traditional circular strokes. Cleaning at the end of each day, with the utmost respect for your home.
- Complete drying and acceptance : the final colour will be visible after 4 to 7 days of drying. A final inspection will take place at this stage, during which the finished result will be approved and the photo portfolio handed over if requested.
