Product Details
High Standards
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.
It's All Inside the Bag
All the materials you need are packed inside:
- Natural Hydraulic Lime (NHL)
- Blended Sands & Aggregates
The lime, sands and aggregate are carefully selected and sourced from around the British Isles.
Easy to Mix
Mixing the render is really simple. All you need to do is stir the lime and aggregate together, then add clean water and mix to the correct consistency.
The product is mixed in its entirety using all the aggregate and natural hydraulic lime provided, this ensures consistent appearance and performance.
There is generally sufficient time to work with the mortar before it reaches an initial set. A little water can be added to the mortar as required throughout the day to keep it workable.
Integrity is Everything
As a heritage product, the hydraulic lime render's performance depends on the integrity of the natural material.
The tough, waterproof packaging keeps the material in perfect condition which is critical given it's hydraulic nature.
The material is not compromised in damp or wet conditions. It is also protected from internal condensation in hotter temperatures.
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.

* Masonry density can vary by quarry, manufacturer, age and condition of material, this information serves only as a general guide, disclaimer.
** 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 should be stored with packaging unopened, natural hydraulic lime is vulnerable once open and exposed.
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.
