Doesn't that skim and sand take ages and creates lots of dust?
Wouldn't it be easier just to get a skim done? Or if it is really poor dryline?
Also paint pad :P

Maybe skim with plaster would be quicker if you had the skirting off the room. Can get problems with super thin skims on some friable renders. If the skirting is on you either lose some depth of skirting moulding or have to fix the edges next to the skirting or minimum clean the skirting. Plaster dust aftermath is usually worse than filler.
I have a 225mm long necked sander with a massive dust extractor which is designed to sand pb joints which makes the job easier, they are more popular on the continent where they don't skim plasterboard. You could just use a wet sponge to smooth out the worst of it after it dries, Easy Fill is very good like that or just make a good job of plastering it! Skimming a 8ft 4m wall should take about 30-40 mins or less.
Never been able to use paint pads as they leech the very fine hair into the paint. I've not tried every one on the market but there is a reason why they are not more popular than rollers.

Clean the wall with a product to remove any wall paper paste residue. Sand it with 100 grit and apply a watered down coat of emulsion (mist coat). There are lots of different opinions on the best emulsion brand to use as a mist coat, I would usually use something mid price like Leyland brilliant white emulsion, if you only want to use one type then Dulux Trade Supermatt is a good option. Then apply filler to any of the defects that stand out. I would opt to cover the entire wall with easy fill then sand it back but you can just pick out any problems, feather the filler and paint with an undiluted coat of emulsion. If you plan to use a fancy emulsion as a top coat of colour then start with something that is designed to cover well, a high opacity emulsion like Dulux Trade Supermatt. Denib by sanding between coats and don't lay it on too thick as you'll just end up with a terrible roller pattern.
If I were doing this in my own home I'd use a lining paper, 1100 or 1400 weight.
