Lafarge Natural Hydraulic Lime (NHL) 2.0 is a very white, slightly (feebly) hydraulic lime produced in France. The lime has more free lime (non-hydraulic lime) and less clay than any other NHL we are aware of. The material is ‘buttery’ and makes it excellent for interior plaster finishes and for delicate exterior restorations involving the preservation of deteriorated masonry.
Lafarge NHL 2.0 is often used for interior plaster finishes (in all three coats) because the hydraulic set speeds up application times. But it is also used for the stabilization and repair of damaged soft masonry units such as brick, sandstone, marble or others where the mortar is intended to be sacrificial. Lime mortars of all kinds are intended to pull water away from the masonry units they surround. Lafarge NHL 2.0 is soft enough when fully cured to protect compromised masonry.
