Consumption

For Repointing work the following volumes are required 20kg/m2 stonework; 7kg/m2 brickwork dependant upon the joint size. For brickwork 1 tonne of dry mortar will be needed to lay approximately 1000 bricks.

Lambs Natural Lime Mortar is available in 25 Kg bags and 1 tonne bulk bags. The 25 Kg bags have a shelf life of 6 months from the date of manufacture provided they are stored in dry conditions. The 1 tonne bulk bags can be used with a mini silo system.

Mortar application Natural Lime Mortar type
General solid masonry, dense masonry, parapets and lintels Medium mortar

Above roofline, below DPC incl. copings and cappings, earth retaining walls Strong mortar

The correct specification for any mortar should consider the structural requirements, nature and condition of the background, site exposure, time of the year and type of finish required. Less porous masonry units and harsh climates require greater mortar strength.

Lambs can arrange site visits to match historic mortars where required, please contact the Sales Office.

 

Benefits

  • Walls breathe (vapour permeability)
  • Low shrinkage (reduction of cracks)
  • Excellent adhesion
  • Maintains the mortar's low modulus of elasticity (better resistance on a soft support)
  • Warm natural colour (light ochre)
  • Fast set allowing work to continue in adverse condition
