Lime-based paints and plaster can improve indoor air quality in several ways, as they are:

• Safe: Lime is natural and does not contain harmful chemicals or toxins.
• Breathable: Lime allows moisture to evaporate, which can help to prevent mould and mildew growth
• Antimicrobial: Having a high pH (12+) lime has natural antimicrobial properties that can help to inhibit the growth of microorganisms such as moulds and also bacteria, even in hot and humid environments.
• Zero VOC: Volatile Organic Compounds (VOCs) are completely absent in our lime-based products.
• CO2-Absorbing: For years after its application to walls lime absorbs CO2 from the air and stores it. This process, known as carbonation, can help to reduce the levels of carbon dioxide in the air.
• Humidity regulators: Lime can balance the humidity level in the room, thus helping in the prevention of respiratory problems.
• Carbon neutral: Lime plaster is produced at much lower temperatures than cement, making it a more sustainable alternative.

Lime has a long history as a building finishing material, with a proven track record of longevity. Used primarily in the production of mortar and plaster, lime provided durability and resilience to structures. The Romans used lime to create their renowned concrete, enabling the construction of enduring architectural marvels such as aqueducts and amphitheaters. In the humid Venetian lagoon, it was extensively used for both interior and exterior wall finishes of palaces. Today, we can still see these finishes in good condition even after decades of exposure to time and weather.

One of the main reasons for the durability of lime plaster is its permeability and breathability. Unlike cement, lime allows for the diffusion and evaporation of moisture, preventing its accumulation and erosion of the surface. Additionally, being porous, lime is more flexible and less prone to cracking than cement plasters. Another benefit of lime plaster is its high pH which acts as a natural fungicide, preventing mould growth on the surface. This is especially important in damp and humid environments. Furthermore, lime plaster is less affected by water and will not soften or dissolve like clay or gypsum plasters.

Lime possesses an intrinsic, living beauty that acrylic and other synthetic binders cannot replicate. The subtle variations in texture and colour typical of lime-based finishes contribute to a unique aesthetic that enhances any architectural style, whether modern or traditional. Each application creates a distinct surface that reflects light in a gentle, diffused manner, lending an organic tactile quality to walls. Lime finishes are revered for their natural look, which ages gracefully, acquiring a patina that adds depth and character over time. The evolution of the plaster’s molecular structure and appearance allows buildings to express their rich history through their very walls.
