We offer a range of coloured mortars for matching historic lime pointing.
Blending selected coloured sands with lime putty creates special mortar mixes which closely match historic mortars. You can request sample biscuits to match your mortar, or alternatively we are happy to offer guidance on the closest available match if you send us a sample of the mortar in the post.
The image below shows a selection of lime mortar biscuits that we can mix and supply for specific requirements for colour and texture. Many special mortar mixes are charged at a slightly higher rate than the standard mortar.
