Best suited for soft masonry* Masonry Density Chart
Non-hydraulic lime mortar is most suited to soft / low density building materials or masonry in poor condition that is prone to decay, crumble, scale or flake and where conservation is the principal requirement.*
Suitable for joints with a thickness of 10mm or more
Medium Stuff mortar has a medium texture and is suitable for bedding, pointing and repointing joints with a thickness of 10mm or more. Sometimes masonry has non-standard joints of varying thickness, this is very common with random stone walling. Where this is the case, find the narrowest joint in the structure and select a lime mortar suitable for that.
Not suitable for use with a pointing gun
The consistency of this product is not suitable for a pointing gun. Although additional water may eventually facilitate an adequete flow, this practice should be avoided as excess water will cause the separation of lime from aggregate and thus compromise the mortar. Where a pointing gun is required see Gunlime®.
Product Details
High Standards
Non-hydraulic lime mortar is CE certified and is manufactured to British Standards BS EN 998-2:2016 following heritage guidelines.
Authentic, Pure and Simple
100% natural, breathable and sustainable. The mortar doesn't contain anything artificial, no additives or plasticisers and absolutely, certainly no cement.
Premixed
Inside the bag you'll find a premixed lime mortar, ready to use, it is made with matured non-hydraulic lime (commonly known as “lime putty” or “fat lime putty”).
Non-hydraulic lime mortars set by carbonation, very gradually. This characteristic gives the product a long shelf life providing that the material is kept sealed air-tight preventing carbonation.
The mortar may stiffen over time in storage but can be “knocked up” again and again to the ideal consistency providing it is stored correctly.
Economy & Convenience
These bags are popular with building contractors as they're economical and practical for projects large and small.
Orders for 8 or more bags are typically delivered using the UK's largest pallet network companies to keep delivery costs to a minimum.

** Exposure is approximated and can vary, this information is presented as a general guide, disclaimer.
† Technical data is approximated as it can vary significantly depending on various factors, particularly weather conditions. The information presented outlines typical behaviour you might expect in the United Kingdom with ambient temperatures of 10°C in sheltered areas with low exposure to wind and moisture. The information is nevertheless useful to establish the relative properties and performance of different products, disclaimer.
‡ The colour of the mortar will continue to lighten until it fully cures. This difference in colour can be quite dramatic. In good weather, the mortar will appear much lighter after 10 days.
§ Products must be sealed airtight in their packaging during. Material will stiffen over time when sealed but can be 'knocked up' back to a workable state.
Disclaimer It is the customer's responsibility to determine the suitability of this product. Samples should be prepared and approved before complete application of this product. Appropriate testing should be undertaken prior to application where compressive strength or density are a critical factor.
