Why Use Lime?
Lime has been used as a plastering material for centuries due to its excellent properties. Here are some reasons why lime is used for plastering:
Breathability
Lime plaster is highly breathable, allowing moisture to evaporate and pass through the material. This characteristic is especially beneficial in older buildings or structures with limited or no damp-proofing measures. It helps to prevent moisture build-up, condensation, and subsequent damage to the underlying materials.
Thermal Performance
Lime plaster has good thermal properties, helping to regulate temperature and moisture within a building. It can act as a natural insulator, reducing heat loss and improving energy efficiency.
Eco-Friendly and Sustainable
Lime mortar is more environmentally friendly than cement-based mortars. The production of lime mortar requires lower energy inputs and generates fewer greenhouse gas emissions. Additionally, lime mortar can be recycled and reused more easily than cement-based materials.
Flexibility
Lime plaster is more flexible than cement plaster, which makes it ideal for use on walls that are prone to movement. This flexibility helps to prevent cracking and ensures that the plaster stays intact for longer.
Self-healing
Lime plaster has the ability to self-heal minor cracks that may appear over time. This means that the plaster can repair itself and maintain its integrity for longer periods of time.
Historic Authenticity
Lime plaster has been used for centuries in historic buildings, making it an ideal choice for restoration projects or in buildings where historical authenticity is desired. It helps preserve the character and integrity of historic interiors.
Durability
Lime plaster is known for its durability and can last for many decades. This is because it is less prone to cracking and has a natural resistance to weathering.
Aesthetics
Lime plaster has a unique, natural appearance. It is also available in a wide range of colours, textures, and finishes, making it a versatile choice for a variety of applications.
Overall, the properties of lime plaster make it an ideal choice for many different applications, including historical restoration and sustainable building practices.
