Hi
I have read that old houses need to breath .
The mortar to be used should not be sand and cement as this prevents breathability.
Om Old buildings lime and sand was used.
This is breathable.
If cement motor was used this changes the dynamics because no longer is there lime instead hard cement based motor which is impermeable
You have to use a breathable mortar mix
