Lime-based plasters and renders have several benefits over cement-based plasters and renders.

First, lime is more environmentally friendly than cement. Lime is a natural material that can be produced with minimal energy input, whereas cement production is a significant source of greenhouse gas emissions.

Second, lime plasters are more breathable than cement plasters. This means that they allow moisture to pass through the plaster, preventing the buildup of moisture within the walls and reducing the risk of mould and mildew growth.

Third, lime plasters are more flexible than cement plasters. This means that they can better withstand movement in the building without cracking. This can be especially beneficial in older buildings where the walls may have settled over time.

Fourth, lime plaster is much more repairable than cement plaster. Lime plaster is softer than cement plaster, meaning it is less likely to crack, chip or flake, and if it does, it can be repaired with a simple slaking process.

Finally, lime plaster has a higher pH level than cement plaster, which can help to neutralize pollutants and other harmful substances in the air.
