Lime Mortar – made in Devon by leading UK supplier Mike Wye from *mature Lime Putty and specially selected sands.
*Mike Wye 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.
Mixed at a ratio of 3:1 (sand:lime).
Use for internal and external building, lime rendering and lime plastering, and lime pointing (add a pozzolan for external use).
Special Colour Mix Mortars for Matching Historic Lime Pointing.
We blend selected sands with lime putty to create special colour mortar mixes which closely match historic mortars. You can request samples to match your mortar or alternatively you can send us a piece of the existing mortar in the post for us to offer free advice.

Our standard range of mortars are available for immediate dispatch throughout the UK. However, please allow an additional 3-5 day lead time for special coloured mortars as these are generally made to order.
Haired Lime Mortar.
Mixed at a ratio of 3:1 (sand:lime).
Use for backing coats of lime plaster and lime render. We also supply Extra Haired Lime Mortar for the scratch coat on to lath ceilings (with pozzolan).
Haired Lime Mortar uses 2 kg of natural animal hair per m3 of mortar.
Goat hair mixes available on request.
The high alkalinity of lime will dissolve natural hair. Therefore we recommend you use haired products within 2-3 weeks. You can still use the mortar beyond this period but may need to tease additional hair back in.
