Fitting board to timber battens

[trogg]

Hello,
I'm not a expert but I do quite a bit of taping and jointing on property refurbishments​, however this is either dot and dab or screwing to study partition.
On my latest project the walls look ok but the plaster on a lot of it has actually lifted off the brickwork, so dot and dab is out the question and I don't fancy removing all the plasterwork,
So I'm going to batten it.
My question is what timber should I use, I was thinking of using 25x50mm roofing battens.... what do you think ?

If you fix battens to wonky plasterwork, you will get wonky walks. Better to fit a gypliner system.

Plasterwork is not wonky and I did think about using MS batten however I've never used this system before, but I quite often use timber stud walls so I thought timber would be the best way for me to go, however I don't want to fit 4x2 or 3x2 to the existing walls when something smaller will do, if MS is the way to go then I'll give it a go.

Thanks for your help TonyM
