It is always a delight to provide lime training to the teams and volunteer groups working for the Canal and River Trust. We were at Apperley Bridge Depot today and built a wall with a mortar similar to the feebly hydraulic hot lime mixed used on one of the buildings within this complex. The mix was composed of quick lime, two sands, ash and brick dust.

The group also wanted to have a go with the most appropriate mix for repointing setts at this time of year. We used a mix of Ionic Old White NHL3.5: two parts Sharp Sand: half part clinker ash and 10% prompt just before use.
