Lime plaster is type of plaster composed of hydrated lime, sand and water. Lime plaster is similar to Lime mortar, the main difference is the based on use rather than composition. Traditional lime plaster contains also horse hair to reinforce plaster.
It is sold as 'bagged' powder or hydrated lime; or is available as lime putty. Lime putty is generally considered to be more suitable for pure lime application.
Non-hydraulic lime is the most commonly used and known lime, also called (high) calcium lime or air lime, as it sets only by reaction with CO2 in the air and will not set until dry. This causes limitations in construction use as the lime can remain soft for months or years. Non-hydraulic lime can only set through carbonatation (re-absorption of CO2).
Hydraulic lime and hydrated lime must not be confused. Hydrated lime is merely a form in which lime can be supplied (as opposed to quicklime or lime putty); while 'hydraulic' refers to its ability to set under water, or in wet conditions.

“This Land of Saints,” and then as the applause died out,
“Of plaster Saints;” his beautiful mischievous head thrown back.”
