Non-hydraulic lime render is CE certified and is manufactured to British Standards BS EN 998-1:2016 following heritage guidelines.
Authentic, Pure and Simple
100% natural, breathable and sustainable. The render doesn't contain anything artificial, no additives or plasticisers and absolutely, certainly no cement.
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 renders 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 render may stiffen over time in storage but can be “knocked up” again and again to the ideal consistency providing it is stored correctly.

† 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 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.
