Lime pointing of internal flags prior to cleaning?

[Itchinfilth]

Hi all,
Happy Friday!
Has anyone any idea how long lime pointing on internal flags takes to be 'safe' to take a good general deep clean without the pointing being damaged? I mean without having to skirt around the pointing with a mop.
NHL2 used for pointing.
I keep having nightmare visions of smearing or damaging the pointing if not ready to take a mop!

Wouldn't have thought it would be too long. Couple of days or a week maybe. It just needs to dry and doesn't need to wait to cure.
