Womersleys Natural Pre Mixed Mortar

Description:

Womersley’s Ironstone range with medium strength Natural Hydraulic Lime (NHL 3.5).  The NHL 3.5 binder from both St Astier and Socli is 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 premixed mortars are batch blended for consistency, naturally coloured and contain 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.

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.
