Getting Started - Why use lime mortars?

Its breathable!
Lime mortar is highly breathable allowing water to pass through the building thereby avoiding a build-up of moisture within the fabric and the risk of subsequent condensation or damp taking hold.
Its sustainable!
Lime mortar is a truly an environmentally friendly building material in its production, its use and afterlife. Our lime putty is produced at our manufacturing site in Llangasty and we are continually working to improve the environmental credentials of our products, looking for more sustainable alternatives to freshly quarried sands which deplete a finite natural resource. By working with suppliers in the recycling sector, we are proud to say a number of our aggregates are now sourced from recycled building materials, the waste materials are processed, washed and then graded to ensure they meet the criteria required for Lime mortars.
Its flexible!
Because lime mortar is a flexible material, it will move with a building as natural thermal expansion or contraction occurs. If a hard, brittle, inflexible material such as cement is used, large cracks will develop, and the material will move away from the substrate (known as debonding) which is likely to also damage the substrate.
