Help with patching plaster please pics inside

[mood]

Hi

I'm redoing both the bedrooms in my terrace house before i go travelling. I want to get the walls skimmed so i can redecorate but the problem ive got is that when i took the wallpaper off alot of the plaster was cracked and lose against the wall so it had to be removed which has left me with this see pics.

If you look at the edges they are all diff depths from the wall at the top the plaster comes away from the wall about 1 1/2 inches and at the sides its all around an inch from the wall.

My question is how do i prepare this for skimming? my next door neighbour said cut up plasterboard and use some kind of adhesive to stick the board to the brick. How do i get it all level if all the edges are different depths from the wall?

Thanks aaron

are you preparing it to skim yourself? Use browning to fill the hole and rule off the door casing with a straight edge to get it flat.

browning? sorry m8 don't understand what that is? I'm not skimming gonna get a plasterer to do that just thought it might be cheaper to do the filling myself so that he could just come in and skim.

I got a quote today though to skim 4 walls and fill the patches £300 so i'm gonna go with that i think the guy said he would fill the patches then skim the other walls and then skim that wall last he seemed to know what he was talkin about said it was to small to dot n dab all whatever its called sound ok?
