Dry slaked lime


Lime has many advantageous properties over cement; it is weaker than the bricks, masonry and stones, yet it is able to support the full weight of the structure. This gives the building the ability to flex and move without the purpose of movement joints. There are many other benefits for using it too.

Breathability 2

A common problem with modern houses is they are becoming less and less breathable. It also allows moisture to evaporate and wall to breathe.

Absorbs Co2

When curing process starts it re-absorb CO2 from the atmosphere.

    Recycle Masonry 2

It allow masonry to be recycled at the end of the buildings life.

Reduces Expansion Joints

Modern buildings using cement will generally have an expansion joint every 8 metres.  You can have an expansion joint every 20 metres.


Lime mortar has a low modulus of elasticity, which allows for slight movement and thermal expansion throughout the life of the building.

Resistance To Cracks

Lime sets slowly and to a lower strength compared to cement. This reduces the possibility of cracks to form in the wall.

Which Lime Should I Use?


NHL 2 is the softest of the three strengths which has the slowest setting speed and is mainly used with soft or deteriorating bricks and stones.

NHL 3.5

NHL 3.5 strength can be used for permeable masonry materials which is mainly used above ground. Generally, it is used for bricks, facings, commons, blockwork, bedding, sandstone, limestone, flint, terracotta, cavity, solid walls, pointing and repointing.


NHL 5 strength is commonly used for the foundations of buildings, coastal locations, or for parapets, coping’s and chimneys in external areas.

Why Use Lime Mortar Colours?

When lime was used in construction of buildings, the sand used was sourced locally due to the costs involved and not having transport readily available to deliver it from the quarry to the building site. Most conservation areas have a bespoke colours, which was inherited by the colour of the sand. For example, Cotswold has a yellowish colour to its mortar and depending where you visit across the United Kingdom; you will be able to see an array of colours used.
