Suitable for all historic masonry structures without hydraulic binders originally present

Hydraulic Lime Mortar is a breathable restoration mortar that is typically used for historic masonry that must tolerate extreme weather and/or persistently damp conditions. Like Portland cement-based mortars the primary chemical curing reaction is rapid and hydraulic. This means it sets quickly, even in damp environments. Unlike Portland cement-based mortars, which can be extremely rigid and brittle, natural hydraulic lime mortar has a low modulus of elasticity. This makes the mortar flexible, absorbing natural movement in masonry walls to resist damage to masonry units during adverse conditions.
