How to strengthen brickwork which has spalled from removing plaster

[HaloThree]

Removing old plaster from this solid brick wall with an SDS has left it looking a little worse for wear.

 

We're going to build a stud wall/battens in-front of this wall to bring it flush with the new extension cavity wall - I was wonder if it's worth mixing up some mortar or similar to give the bricks a bit more strength.. some are wobbly.

 

Thoughts?

Definitely worth it, to secure bricks and from droughts etc

Might be worth using some expanded metal lathe fixing that first and cement rendering over.
