hydrated lime

Dry hydrate of lime. Often included to weaken cement mixes to resemble lime mortar. The result is a softer cement mortar, but lacking in flexibilty, permeability and bonding. Questionable results over time led to the re-introduction of lime putty.

non-hydraulic lime

Slow setting, lime putty mortars are highly permeable. The porosity and softness provides a sacrificial bond with brick and stone protecting the building by slowing deterioration and damage caused by the environment.

hydraulic lime

Packaged and prepared in a similar fashion to cement and sets as quickly. Used where lime putty mortars would otherwise require specialist application and care (chimneys, wall copings, mill races, water defences, flooring).
