If you really need to chisel it out with an sds then it probably

Potential diy disaster looming here!

Yes I realise this. Reason for SDS is twofold...
There are some small areas which strictly don't need it, but I
don't want to leave them looking different from the rest of the
wall. Secondly, some parts have been done with a very hard cement
mortar (on a lime mortar house). These have of course all cracked
away from the brick on one side, but it's still hard work.

It can all be done by hand, but it's taking too long.
