Hydrated Lime vs Hydraulic Lime - Traditional Building

Hydrated - lime that has been slaked. Hydraulic - lime that has a clinker of reactive silica compounds that will set with water. Non-Hydraulic - lime that sets only by reabsorbing CO2 from the air. Also called a pure, air or fat lime. Putty - non-hydraulic lime that has additional water so as to form a thick paste.

When lime mortar dries too quickly it results in whitening on the surface. This is the lime being drawn to the surface. As mortar carbonates it needs to dry out slowly. It needs to be kept moist (not wet) for at least 10 days. This aids the process of carbonation. Keeping the work moist can be achieved by the use of a garden pump sprayer.
