Would you add plasticiser (or washing up liquid) to shed-bought
ready-mixed mortar?Â* That's what I used on this latest effort, but
with nothing added.

yes. All you have bought is premixed sand and cement.

Mortar Mix" is a traditional 6:1:1 sand/cement/lime mortar and lime is a
time-served plasticiser.

after a hundred years you can pick out the bricks in a lime mortar wall.....
