Tradiblanc is a modified hydraulic lime binder, manufactured by Saint Astier in France. It is also based on NHL 5 with the addition of a small proportion of a white low sulfate cement and additives to improve workability. Tradiblanc is similar to Hourdex, however the colour of the binder is ” off white ” so this allows for better sand colour reproduction for site mixed mortars. Tradiblanc can also be used to make mortars for a wide range of applications including : Building, re-pointing, renders and roofline work. Tradiblanc develops its compressive strength and resistance to freeze thaw more quickly than a pure NHL and mortars produced using Tradiblanc offer excellent workability and breathability.
