Description
Lime Mortar is made in Devon, UK with Mike Wye & Associates *matured Lime Putty and specially selected sands.
Lime mortar is traditionally used as a bedding mortar, for lime pointing, lime plaster backing coats and lime render. Contact our friendly technical sales staff for more information about how best to use lime mortar.
You can find additional information on the different types of building lime on our FAQs page or Natural Hydraulic Lime site.
For more information on the use of lime in floors, visit our dedicated Limecrete website.
*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.
Unhaired Lime Mortar.
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).
Haired Lime Mortar.
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).
Haired lime mortar is made by mixing mature lime putty, specially selected sands and animal hair.
Haired Lime Mortar uses 2 kg of natural animal hair per m3 of mortar. Goat hair mixes are available on request.
You will need to use Haired Lime Mortar needs within 2-3 weeks as the hair will gradually dissolve in the alkaline lime. The mortar is still usable if you tease fresh hair back into it.
Extra Haired Lime Mortar.
3:1 ratio (sand:lime). Suitable for scratch coat onto lath ceilings.
Extra Haired Mortar uses 3 kg of natural animal hair per m3 of mortar.
We offer a range of coloured mortars for matching historic lime pointing.
Blending selected coloured sands with lime putty creates special mortar mixes which closely match historic mortars. You can request sample biscuits to match your mortar, or alternatively we are happy to offer guidance on the closest available match if you send us a sample of the 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. Many special mortar mixes are charged at a slightly higher rate than the standard mortar.
