Lime Putty

Pure limestone burnt and then slaked into a putty. Traditionally used for thousands of years and the base ingredient of many of our products. It makes a soft and very breathable mortar which should be used in sheltered locations or internally.

Limestone (Calcium Carbonate – CaCO3) is burnt in a kiln giving off Carbon Dioxide (CO2) gas and forming Calcium Oxide (CaO) which is commonly known as Quicklime or Lumplime. It needs to be burnt at 900-1100°C.
