We use high calcium British quicklime in the production of our lime putty. This is added to water and a chemical reaction occurs which is termed as slaking. The resulting mixture is left to mature for at least 6 months. During this time the slaked lime thickens to the consistency of toothpaste and is pure white in colour.
220kg of lime putty (11 Tubs) is needed to make 1 tonne of lime mortar when mixed with 3 parts (by volume) of sand.
