About Lime

Lime has been used extensively in traditional buildings across Britain and Europe

It is unique in that it allows the structure of a building to ‘breathe’, as well as providing flexibility

It is essential to replace like-for-like to prevent problems caused by the use of modern materials on heritage buildings. Handled in the correct way, lime is an excellent binder, and is a very rewarding material to work with.

The lime cycle

The lime cycle is a fantastic natural example of chemistry. This classic series of chemical reactions forms the basis of the application of lime techniques.

Chalk or limestone (calcium carbonate) turns into quicklime after heating, then into hydrated lime (slaked lime or calcium hydroxide) after adding water and finally back into chalk by combining with carbon dioxide from the air.
