The Ironstone range of Dry Premixed Natural Hydraulic Lime Mortars have been
manufactured in partnership with Heidelberg Materials using their high-performance NHL 3.5 binders and carefully selected kiln dried sands. 

The Ironstone mortars are natural and highly workable, combining long term durability with breathability for building and re-pointing. The range has been developed to ensure a traditional heritage finish and is available in a range of 12 colours with various aggregate sizes as specified - just add water
