Manufactured with high-performance NHL 3.5 binders and kiln-dried sands, it offers exceptional durability, workability, and a traditional heritage finish available in 12 natural colors. Pre-mixed for convenience, it ensures consistent quality and a textured finish that enhances any restoration or building project. ## Description Ironstone Pre Mixed Natural Hydraulic Lime Mortar NHL 3.5 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. See our aggregate chart for sand aggregate sizes. The sands are prewashed to remove sediment before being dried and the result is a very workable mortar with reduced risk of shrinkage. Ironstone premixed mortars are batch blended for consistency and naturally coloured from a range of sands to give the desired finish and texture. Coverage: A 25kg bag will yield approx. 14 litres of mortar sufficient to repoint 3-5m2. Repointing: 20kg/m² stonework; 7kg/m² brickwork. Application: Mixing can take place in a tub or mixer. If you don't require the full amount of mortar, just take out what's required and seal the remaining in a tub or bag. Use between 4-5 litres of clean water per 25kg or approx. 2 litres per 12kg Tub. Add the water slowly, using just enough to achieve a workable mix. Lime mortars benefit from being left for 15 mins to fatten after mixing and can be reworked for up to 4 hours. To ensure good compaction and adhesion the mortar can be tampered firmly with a bristle brush as it starts to firm up, normally after 2-4 hours, this process also brings the sharp aggregate to the surface creating a lovely textured finish. Review: All good - Good product. Mixed well, easy to use for repair pointing a sandstone wall. Price was good, packaging sturdy and delivery was cheap and quick.
