The Amazing Self-Healing Properties of Lime Plaster

The Amazing Self-Healing Properties of Lime Plaster

Posted on 10-Nov-2023

Lime plaster is a versatile and durable building material that has been used for centuries. It is known for its breathability, flexibility, and long-lasting nature. What is less well-known is that lime plaster also has the remarkable ability to self-heal cracks that develop over time.


How Lime Plaster Self-Heals:

When lime plaster is exposed to air, it undergoes a chemical reaction called carbonation. During this process, the calcium hydroxide in the plaster absorbs carbon dioxide from the atmosphere and transforms it into calcium carbonate. As the lime absorbs carbon dioxide and converts to calcium carbonate, tiny crystals form within the plaster. These crystals work to fill the gaps in the material, including small cracks.


Benefits of Lime Plaster's Self-Healing Properties:

Lime plaster's self-healing properties offer a number of benefits, including:

  • Longevity: Lime plaster is known for its long lifespan. Its self-healing ability helps to keep the material in good condition for many years, making it a great choice for historic preservation and restoration projects.
  • Reduced maintenance costs: Structures coated with lime plaster require less frequent maintenance and repairs, saving both time and money in the long run.
  • Sustainability: Lime plaster is an environmentally friendly building material. Its self-healing properties mean less waste and a reduced need for replacements, which is in line with sustainable construction practices.
  • Versatility: Lime plaster is versatile and can be used for a variety of applications, from interior to exterior walls. Its self-healing capability ensures that it remains a good choice for different construction needs.



While lime plaster's self-healing properties are impressive, there is one thing to keep in mind:

  • Time: The self-healing process of lime plaster is gradual and may take some time. While it can address minor cracks, extensive damage may still require intervention.



Limocoat lime plaster is a superior choice for home improvement projects due to its high-quality ingredients, a wide range of finishes, easy application, breathability and moisture resistance, self-healing properties, versatility, durability, and sustainability. It is a wise investment for any homeowner who wants a durable, sustainable, and versatile building material that can withstand the elements and heavy use.

  • In addition to the above, here are some other key takeaways from the blog post:
  • Lime plaster has been used for centuries in construction, and its self-healing properties have been observed in many ancient structures.
  • Lime plaster's self-healing ability is due to the carbonation process, which leads to the formation of calcium carbonate crystals within the plaster.
  • Lime plaster's self-healing properties offer several benefits, including longevity, reduced maintenance costs, sustainability, and versatility.
  • While lime plaster can self-heal minor cracks, extensive damage may still require intervention.

Overall, lime plaster is a unique and valuable building material with a number of benefits, including its self-healing properties.
