NHL 3.5

It is a pure medium-strength white NATURAL HYDRAULIC LIME from SAINT-ASTIER, produced using selected siliceous limestones.

The limestones are fired in vertical kilns at a temperature of less than 1,250° C and reduced to a powder by extinguishing the calcium oxide alone, without the need for grinding. NHL 3.5 is totally free of pozzolanic materials, blast furnace slag, fly ash or hydraulic binders of any kind (clinker, cement, etc.), VOC and is compliant with UNI EN 459-1.

Fields of application


Pure Natural Hydraulic Lime NHL 3.5 can be used directly on the building site as the sole binder for mortar for masonry in elevation, as bedding or grouting mortar, in consolidation works by injection, for structural mortars with TCS Consolidation Line meshes, traditional plasters and as sub-base screeds or flooring. Mortars and plasters made from Pure Natural Hydraulic Lime NHL 3.5 can be directly applied to vertical and horizontal surfaces consisting of solid brickwork, load-bearing hollow bricks, light hollow bricks, mixed bricks, rubble and tuff. For all those surfaces that are compact or not very absorbent, such as concrete blocks, expanded clay granules, cellular conglomerate, lime or cement-based rolled surfaces, reinforced concrete or magnesium wood structures, the use of mortars made on site with NHL 3.5 lime must be preceded by the application of SPRIZZO PONTE DI ADESIONE.
