Saint-Astier® white natural hydraulic lime NHL 3.5 is produced by calcination and quenching of an exceptional chalk and silica-based limestone without any additives. It combines air-curing and hydraulic bonding and is suitable for the preparation of mortars and plasters. Its specific properties such as plasticity, vapour permeability make it particularly suitable for the restoration of buildings. Its white natural colour closely follows the colours of the sand and its purity and gradually increasing resistance allow it to be used on all substrates without the addition of cement.

Saint-Astier® hydraulic lime NHL 3.5 complies with the latest European Standard EN 459-1.
