Lime finishes – whether paint or plaster – are alive, breathing and deeply sensory.
They create soft, velvety interiors that patina elegantly over time.
To maintain their beauty and extend their durability, proper maintenance is essential.
Here are our tips for respecting the mineral nature of your walls and allowing them to age gracefully.
⸻ 1. Understanding lime surfaces
Before discussing maintenance, remember that lime is an alkaline material (with a high pH). It is this alkalinity that gives it its antibacterial properties and longevity. It remains microporous, allowing the surface to breathe, making it an ideal choice for a healthy home. However, this alkalinity makes it sensitive to overly acidic products (such as vinegar), which can attack the surface and alter the color.
⸻ 2. Gentle and respectful cleaning
What to prioritize
• Liquid black soap (diluted in lukewarm water). It is ideal for cleaning light stains, while lightly nourishing the surface.
• Neutral organic soap (like Marseille soap or Castile soap). Mixed with warm water, it gently cleans without damaging the lime.
• Soft cloth or natural sponge. Avoid abrasive brushes which may polish or shine the surface unevenly.
⸻ 3. What to avoid
• Acidic products (vinegar, lemon)
• Aggressive detergents or chemical solvents
• Cleaners containing ammonia or bleach
• High pressure jets
⸻ 4. Maintenance of lime paint
Lime paint is delicate but easy to refresh.
- Dust regularly with a feather duster or dry cloth to prevent dirt from becoming embedded.
- Localized cleaning with a very diluted solution of black soap for small splashes (especially in kitchens).
- Easy touch-ups: If an area is too stained, you can apply a thin coat of the same diluted paint to even out the look, or use our annual maintenance service.
⸻ 4. Maintenance of lime plaster
The coating, thicker and more mineral than paint, is generally more resistant.
• Gentle wash with natural soapy water for high traffic areas or surface stains.
• Possible protection: in humid rooms or areas of frequent contact, you can apply a finishing wax or soap to reinforce the waterproofing, while maintaining breathability.
⸻ 5. Living with the patina
Lime-washed surfaces aren't meant to remain static. They evolve with time, light, and the seasons. This natural patina is what makes them unique and authentic. Rather than trying to keep them "perfect," take a respectful approach and let them tell your story.
Maintaining your limewashed walls doesn't require complicated products: a simple black soap or organic soap will suffice. The key is to respect their mineral nature, avoid acids, and favor gentle cleaning. This way, your surfaces will remain beautiful, healthy, and elegant for years to come.
