Womersleys Ironstone Lite Pre mixed Mortar NHL 3.5
Womersleys Ironstone Lite
Ironstone Natural and Breathable mortar is a dry pre-mixed lime mortar made with Tarmac Hydraulic lime. The lime is blended with kiln dried Nosterfield down and Leighton Buzzard sand. Our sands, which are 3mm down, are always pre washed to remove sediment before being dried and the result is a very workable mortar, with unique colour and texture.
A 25kg bag will yield approx 14 litres of mortar sufficient to repoint 3-5m2.
A 12kg tub will yield approx 6 litres of mortar sufficient to repoint 1.5-2m2
Before pointing remove all dust and loose material from joints. Dampen the area to be repointed first to help curing.
Mixing can take place in a tub or mixer. Use between 4-5 litres of clean water per 25kg or approx 2l per 12kg Tub. Add the water slowly, using just enough to achieve a workable mix. Lime mortars benefit from being left for 15mins to fatten after mixing and can be reworked for upto 4 hours. Application temperature range 5-30 C. Protect against strong sunlight, heavy rain, frost with hessian.
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.
Brushed effect finish to expose the aggrigates can be achieved with a church brush - Churn Brush
