Ironstone Chimney Mortar 25kg

Factory blended Natural Hydraulic Lime Mortar with an eminently strong NHL 5 binder from Socli blended with kiln dried Grit and River sand, which are 4mm down. The sands are prewashed to remove sediment before being dried and the result is a very workable mortar with reduced risk of shrinkage.

Ironstone Chimney mortar uses Socli Natural Hydraulic Lime as it is one of the strongest NHL5’s available and ensures the mortar is resistant to adverse weather conditions.  The chimney mortar is batch blended for consistency, naturally coloured and the aggregates provide a unique and robust texture.

Suitable for applications above the roofline whether pointing chimneys, flaunching or bedding ridge tiles. Suitable in building conservation where a strong binder strength is required to protect the integrity of the building.

 Coverage:

After mixing, a 25kg bag will produce approximately 14 litres of mortar 

Preparation:

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

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 4 hours, this process also brings the sharp aggregate to the surface creating a lovely textured finish.
