Dry hydrate lime mortar
Hot-mixed Lime Mortar, published by Historic Environment Scotland in April 2015 states: ‘When a dry hydrate lime, such as an NHL (Natural Hydraulic Lime), is used on site, it is supplied as a fine powder which is mixed with aggregate and water in specific proportions to produce a mortar. As the lime is already hydrated (by the controlled addition of water during manufacture) there is no ‘slaking’ reaction. Mortar made from NHL or other lime with hydraulic properties cannot be stored for long periods as it will begin to set and harden once combined with water.’
