Fixing messed up wall after removing tiles? Skimming/plastering?

floppydisk1

Don't plaster over paper, strip it off first.  Does not really matter if you make a mess of it and damage the wall while doing it as it will be plastered anyway. AS stated above, it's such a small area you can try it yourself, one coat of multifinsh, let it go off for about 20 - 30 min , run your trowel over it and put second coat of the same mix from the same bucket, flatten straight away and then 3 time more some 20 min apart... It  " might " not be a perfect finish ( as it will be your first go at it ) but small area by the door cab be sanded down later. Plasterer , even on mates rate will charge a day ( might be an easy day ) but still too much for that little bit of a wall you need done. Try first on kitchen, as said correctly earlier, in will be tiled over so use it as a training run, finish on it, or making a mess of it or whatever  makes no difference to tiling job and gives you little bit of practice.

Ideally you don't want to be using the same mix for the second coat, you want to mix fresh, slightly wetter plaster.

  I never charge day rate for small jobs, just a price for the job. And for mates, if they get the plaster etc then it's free.

Thanks, good advice. The wall was just falling apart, so I ended up taking it off back to the lats, the thin strips of wood behind. I have ordered a small trowel, hawk and bucket, and some one coat. So I'll give it a go when that arrives! Depending on how it goes I'll post my results!

One coat isn't very good for filling out, only for skimming in 1 coat...it isn't much good for that either.
Get some Bonding Coat, put that on first. Rule it off flush with the old plaster then take it back a mm.
Give it a couple of hours then skim over it (pva not needed).

Oh dear I already ordered it, and it s abut of a nightmare getting anything currently. I have to queue for an hour just to use the b and q website and many things are not available. I'll see how it goes with the one coat, and if it goes really wrong I'll have to start again!

If you are gdown to the lathe then it can't be done easily with finish, it has to be built out first. One coat says up to 13 mm costs but really anything over 6 or 7 mm is a pain.
  If you take your time you can do it ok but it uses quite a bit of plaster and takes a fair bit longer.

This is a lathe - - You don NOT want to be plastering over one.

These are laths - - Typically, one would use three coats of lime plaster.

The OP may be better off finding a small piece of plasterboard and fixing that to the wall before using the OneCoat.

Thanks, yeah I considered putting some plasterboard in first, but it was quite a thin layer to start with, I don't know if plasterboard and plaster will fit and allow the door architrave to go back on flush

Plasterboard comes in two standard thicknesses - 9.5mm and 12.5mm. A lath and plaster finish is often 20mm or more thick (including the laths). To use plasterboard, you really need a nogging top and bottom to screw the stuff to. In the absence of suitable support timbers, and assuming the laths are in good shape, a base coat of bonding plaster would be recommended. You can apply bonding in quite thick layers and then give the wall a thin skim with a finishing plaster.

Looking at the British Gypsum White Book, boding plaster can be applied to walls in layers up to 11mm thick. OneCoat can go on up to 13mm thick !

If OneCoat is on order, I'd suggest sticking with it. Mix some 20mm screed fibres in for the base coat, and it shouldn't crack.
