Description

Our traditional lime mortar is made from our UK produced matured lime putty and specially selected sands. Our lime putty is made from a refined high calcium quicklime (CaO) that is slaked and left to mature for a minimum of three months.

Lime mortar was traditionally used for bedding, lime pointing and lime rendering and our high quality lime mortars are suitable for various building uses – please speak with our friendly technical sales staff for more information about how best to use lime mortar. Additional information on the different types of building lime is also available on our FAQs page or our Natural Hydraulic Lime website. For more information on the use of lime in floors, visit our dedicated Limecrete website.

Haired Course Lime Mortar Mix.

3:1 ratio (sand : lime). Suitable for internal backing coats of plaster. For the scratch coat onto lath ceilings we also supply an extra haired lime mortar suitable for external backing coats of render (with pozzolan).

Our haired lime mortar is made from premixed mature lime putty and specially selected sands. We use 2 kg of  natural animal hair per m³ of mortar as standard but can arrange for goat hair. 

Haired lime mortar needs to be used within 2 – 3 weeks as the hair will gradually dissolve with the alkaline lime. The mortar is still usable if you tease fresh hair back into it.

Extra Haired Course Lime Mortar Mix.

3:1 ratio (sand : lime). Suitable for scratch coat onto lath ceilings.

We use 3 kg of  natural animal hair per m³ of mortar as standard.

Unhaired Course Lime Mortar Mix.

3:1 ratio (sand : lime). Suitable for internal and external building, rendering and plastering (scratch/float coat <10 mm), and pointing (add a pozzolan for external use).

We offer a range of coloured mortars for matching historic lime pointing.

This is achieved by mixing matured lime putty with blends of suitable coloured sands. We can supply sample biscuits for you to match your own mortar or we are happy to give advice if you send us a sample of your mortar in the post.

The image below shows a selection of lime mortar biscuits that we can mix and supply for specific requirements for colour and texture. We can supply these by post for confirmation that the selected sample is suitable. These special mortar mixes may be charged at a higher rate than the standard unhaired mortar cost.

We do not make a charge for advice on matching the samples. For advice on the use of lime mortar and pozzolan additives, have a look at our “Repair Guidesheets” and “FAQs”.

Our standard range of lime mortars are fully matured and available for immediate despatch. Specialist coloured mortars are typically used for pointing or bedding stone or brickwork where you need to match an existing or the local type of lime mortar. These mortars are made to order, typically with a 2-3 day lead time and some coloured lime mortars cost more than our standard lime mortar.
