QUALITIES OF PRE-BLENDED SAINT-ASTIER® LIME MORTAR
A building continuously suffers structural and thermal movements. By working with suitable lime solutions, you allow the essential movements for a durable renovation
Good vapour exchange qualities allow for condensation dispersion. No Rot. An adequate water vapour permeability decreases the growth of mold and/or algae and improves air quality and the environmental comfort inside your building.
The absence of any potentially damaging additions (i.e gypsum or cement) make sulphate attack and alkali-silica reactions impossible. Existing salts in the building fabric will pass through and eventually wash off. Excellent performance in marine environment.
The permanent alkalinity of the natural lime binder in the premixed solutions inhibits the development of bacteria & vegetable growth
The excellent vapour permeability of Saint-Astier Natural lime mortars reduces moisture in walls, therefore significantly improving insulation levels.
Unlike cement or cementitious mixes, the compressive strength will be achieved gradually, allowing for movement. The availability of a range will permit the making of mortars with the required strength without having to add or blend.
Early setting means less time for protection from adverse weather.
The available lime provides this benefit naturally
Excellent recycling as an aggregate
