Hot mixed mortars have shown to be the superior mortar and are well researched as historically correct through the sampling of many mortars and plasters from all over the world.
Using a mortar produced this way not only gives the lime worker the benefits of workability, it is also more adhesive and cohesive in its character.
The finished mortar, at the correct specification also offers the best practical elements to traditional buildings through its capillarity and function to manage moisture from within and through the external elements of our weather.
This is now being educated through the lime revival and must be considered when we look at working on traditional buildings.
