The quicklime removed from the lime kiln can be stored in barrels in the lime shed for up to a year.

At the start of a new building season, any remaining quicklime is tipped from the barrels—sealed inside with cloths—into the lime pit. This process, known as slaking, is necessary to allow even the less soluble components of the burnt lime to dissolve fully. This step improves the adhesive properties of the mortar later on.

Slaked lime can be stored in the lime pit for many years without any issue—the older, the better. The only requirement is that water must be added regularly. The fine, smooth slaked lime can then be cut directly from the pit for use.

In the Middle Ages, lime painting was a widespread wall painting technique, applied to cured or already set plaster using limewash—a highly diluted mixture of slaked lime and water.
