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

The Ironstone mortars are natural and workable, combing 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 befrore being dried

and the result is a very workable mortar with reduced risk of shrinkage.

Ironstone premixed mortars are a batch blended for consistency and naturally coloured from the range of sands to give the desired finish and texture.

Coverage:

A 25kg bag will yield approx. 14 litres of mortar sufficient to repoint 3-52. Reointing: 20kg/m²  stonework: 7kg/m² brickwork.

Preparation:

Before repointing remove all the dust and loose materials from joints. Dampen the area to be repointing first to help the curing

Application: 

Mixing can take place in a tun or mixer. If you dont require the full amount of mortar, just take out whats 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 the 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, the process also brings the sharp aggregate to the surface creating a lovely textured finish.
