Specialist Mortar Sands

Conveniently packed, and loaded onto your collection vehicle. For pack sizes see individual products.
Ribbon Pointing Winchester UK

Sand for Lime Based Mortar differs fundamentally from "Soft Building Sand" available through builders merchants as this often contains an excess of fine material.

Fine material in Mortar Sand consists of two distinct parts:

Firstly, very fine sand particles (fines) in sizes from around a third to a tenth of a millimetre in diameter.
Excessive amounts of fines will demand more water to achieve a workable mix. This can lead to shrinkage, an increased sensitivity to adverse weather conditions and de-bonding especially to low suction backgrounds.

However, conversely, the bonding of a mortar with a background, and between coats is dependant upon a percentage of these fines being present. Generally up to 20% of fines will achieve bonding without compromising permeability and capillary suction.

Secondly, ultra fine clay (sometimes referred to as silt or loam).These clays have sizes well below a tenth of a millimetre in diameter. Clay minerals are often responsible for a sandís colour, but can retain water resulting in extended drying periods.

The suitability of sand also depends on the range of particle sizes. A quality sand will comprise a range of particle sizes, allowing for the drying of the newly placed mortar and for its long term permeability.

Sands with grain sizes of up to 6mm (Coarse) are suited to general building, those with particle size not greater than 3mm (Medium) are suitable for stipple coats, base coats and rough finishes, whilst smooth finishing coats can be achieved with sands with grain size of up to 2mm (Fine).

Whilst we are unable to provide specific recommendation for application within a lime or cement mortar our 20kg "sample" facility provides an effective method of establishing suitability for use.
