Would multi finish cover this?

    Hiya, I had a friend plaster 2 internal walls but they have ended up looking like this. Don't know why. But could I just multi finish over it? Or would I be better off removing the old plaster and starting again??
    They are brick walls with lime morter. I had the bottom 40 inches removed back to brick and damp proof painted. The a sbr render coat then a multi finish top coat.
    Cheers

    The bottom needs straightening if you want a straight wall it wasn't ruled off properly by the looks of it if you just skim it you will see the dip

    Not too bothered about it being 100% straight. Just flat would be a bonus. It's an old cottage.
    Thanks

    No matter how old the wall wouldn't have a dip like that

    What would you have done?
    Iv gone back to brick, as it was bonding on top of the paint able dp not render, and it hadn't stuck in places, and some of the plaster hadn't stuck to the bonding.
    1) do I have to remove ALL the bonding or just the loose stuff.
    2) what should I do now?? Render on to the dp, then multi finish all of it?.
    Or render just on the dp, then bonding the whole wall then multi finish??

    I will paint the bonding with a 2-6 mix of pva and water 24 hrs before applying a new bonding/plaster an also aply a pva mix just before I start to mix so it's damp an tacky when I'm applying the plaster. Is that the correct method?
    Thinking of the same pva mix but with sand in it and applying that to the dp? Would that give it a key,
    Tia

    I thought all the bonding was taken off and replace with render? I have just looked at your pic you don't use bonding for dp what kind of dp did you use?
