Hi, what are your thoughts on using a mortar made of your lime putty and sand (say, in a 1:3 ratio) for a paving application, both as a bed and as grouting, probably bricks, something like this below (not the final layout, just playing around), on concrete? Is there a durability issue to think about there? It would be exposed to the elements, though thinking about a roof in the future… I want the traditional look of the lime, plus breathability because there will be some contact with timber probably.
