Plasters and interiors
The hydrated lime mortar or slaked lime is worked very easily and is mainly used to make plaster and as a binder for bricks in interiors.
The optimal proportion for its packaging is 1-3-1 that is 1 part of binder (lime), 3 parts of aggregate (sand), and 1 part of water.
If a plaster is to be made, the proportions change. If a rustic plaster is to be made, the ratio can be 1-1.5-1, whereas if a civil plaster with a thickness of a few millimeters is to be made, the ratio reaches 1-1-1.
For the dough it is preferable to combine the aggregate and the binder first, then the water in small quantities until the mixture is soft and pasty.
Turning off the Lime
The "turning off of the lime" was once performed directly on site in the so-called lime pit, the putty was then used directly.
Today the slaked lime is sold in semi-liquid sacks on which the expiration date is not indicated.
The slaked lime should be left to age, with time it improves plasticity, grip and resistance to external agents.
Stretching more with water you will get the lime milk traditionally used as wall paint.
