XhN-101

Hydraulic lime based bedding mortar

Technical Datasheet


Material Safety Datasheet

XHN-101 is a bedding mortar based on natural hydraulic lime from St-Astier. The hydraulic properties of this lime (hardens by reaction with water) allows formulation of a cement free mortar which is closer to the formulation of historic mortars. Its hydraulic set allows installing brick or stone in a reasonable timeframe without using cement or pozzolans. For interior or exterior use, this mortar is specially formulated for the installation of masonry elements on historical buildings during restoration projects were reconstruction is needed. It is also used for new construction for elements that are highly exposed to de-icing salts.
