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

• Non-toxic: lime is natural and does not contain harmful chemicals or toxins. This means that it does not off-gas any harmful molecules into the air.
• Breathable: lime allows moisture to evaporate, which can help to prevent mould and mildew growth
• Antimicrobial properties: having a high pH, lime has natural antimicrobial properties that can help to inhibit the growth of harmful microorganisms such as bacteria and fungus.
• Absorbs CO2: lime absorbs CO2 from the air and stores it. This process is known as carbonation, and can help to reduce the levels of carbon dioxide in the air.
• Regulates humidity levels: lime can balance the humidity level in the room, thus helping in the prevention of respiratory problems.

Our lime plasters are not just healthy for you, but also good for the environment. They are free of Volatile Organic Compounds (VOCs), which can have negative health effects and contribute to air pollution. Additionally, using lime plaster in construction can significantly reduce the carbon footprint of a building in a number of ways.

First, the longevity of lime plaster makes it an excellent green building choice. Unlike other building methods, it does not need to be replaced or maintained regularly, which not only saves resources but also reduces the need for energy-intensive renovation work.

In the construction process, lime behaves differently than cement. Cement requires a higher temperature to produce, increasing the need for fossil fuels and contributing to greenhouse gas emissions. In contrast, lime plaster is produced at lower temperatures, making it a more sustainable alternative. By choosing lime plaster, you can significantly reduce your building’s carbon footprint.

Lime has a long history as a building finishing material, with a proven track record of durability and longevity. It was used extensively in the past for both the interior and exterior walls of Venetian palaces and Italian villas. 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 other materials like drywall, earthen or gypsum plaster.
