The lime based system was chosen to allow the sandstone of the building building to ‘breathe’ as well as protect the substrate from the damaging effects of weather and water ingress.

Unlike traditional Natural Hydraulic Lime (NHL) materials which need to be re-wetted to stop then drying out too fast, Keim Universal Render retains its flexibility and does not craze whilst drying. Future thermal expansion and contraction of the building will not cause the render to crack. Unlike some alternative options, Keim Universal Render did not require any expansion joints, despite being applied to eleven adjoining buildings because of its inherent flexibility.

A mineral paint was selected to provide a high quality, matt paint finish.

The system will provide many years of protection to the building from weathering and moisture ingress, whilst the paint itself will provide a long life decorative finish. Made with only natural materials and earth oxide pigments the colours will never fade and be much more durable than a conventional finish. All Keim Mineral Paints are inherently resistant to mould and fungal growth and in addition the Keim Soldalit-ME has a catalyst which will actively kill mould and fungal spores helping to provide an even better aesthetic finish to the building.
