is it hydraulic lime or hydrated?
if they just want it to look creamier than new mortar i would go 5 sand:1lime:1 cement
however traditional lime mortar contains no cement at all
the biggest problem for you is that lime comes in 25kg bags :;):

It's the two bricks below damp course, it's been painted previously but the paint has come off and the pointing has gone. Once it's been reprointed , he will repaint.

i would'nt bother with lime if its going to be painted. i would use 3 to 1 cement mortar.

Thanks for the replies.
I did suggest this but apparently because its a really old building, it needs it, as cement mortar would be problematic, something to do with moisture.

I emailed him earlier and he says although from outside it looks like it has a dpc (render stops @ floor level) it doesn't so that's why it requires lime mortar?
Maybe I shouldn't do this favour!
