Default How to patch spalling brickwork?

I've got a large North-facing house wall of soft Norfolk red bricks -
and a large number have spalled.

It's really an impractically large number to cut out and replace.

I've been trying to patch over them with lime mortar (lime putty,
sharp sand and red brick dust).

Mix is good consistency & sticky - but it still isn't bonding very
well to the bricks (which have been gone over roughly with a wire
brush, brushed down and then wetted).

So I'm thinking - maybe wet down with 10% pva solution?

Other suggestions?
