What’s the difference between “haired” and “unhaired” lime mortar?
Haired lime mortars contain natural fibres (like horse hair) to provide extra tensile strength, typically for plaster coats. Unhaired mortar does not include fibres, making it more suitable for pointing, bedding, and general masonry work.
