Lime plaster was the traditional finish for houses pre-1919 and was used up until the late 1950s. Cheaper plasterboard and gypsum products became more readily available replacing lime. Lime products have many benefits over cement-based plaster, hence lime plaster and render are still used today. The most impressive feature of lime plaster is its breathability and flexibility. These properties make it an ideal product for conservation and restoration of historic buildings. Most modern buildings have no movement, shrinkage or damp, therefore, cement-based products are fine, whereas older properties that use many different materials and specifications need a product that is more forgiving.

Benefits of Lime-Based Plaster and Render are

Breathable

Lime plaster is breathable (vapour permeable), absorbing and allows moisture to easily pass through it, while cement will trap and prevent moisture from escaping. Using lime plasters on damp walls and environments will allow the structural walls to breathe. A build-up of moisture in a home can lead to failed plaster, damage of structural masonry and cause the growth of dangerous mould and fungus.

Flexible

Whilst cement-based plasters and renders are strong, they lack flexibility. Any movement in a building can easily result in cracking. Cement render traps moisture easily and can cause the render or plaster to fail over time. Lime is more flexible and allows for movement and thermal expansion, minimising the cracks and prolonging the life of the plaster.

Anti Fungal

The alkaline properties of lime are naturally bacteria repellent and thus homes with lime plastering are free from mould and fungal growth. Environmental Lime based products are much more eco-friendly as the manufacturing process produces less carbon dioxide. Furthermore, during the setting process of lime plaster and render, it re-absorbs carbon dioxide, therefore lowering its carbon footprint even further.

Aesthetic

Natural lime reveals the colour and characteristics of the aggregate they are mixed with. They often have an attractive traditional appearance which is pale in colour. By using a breathable paint, lime plaster can have a modern or colourful finish.
