We are redecorating our hall. We have stripped all the wallpaper off and have discovered that the plaster behind is not in great condition.
What suggestions do people have for preparing a slightly damaged wall for painting? (See photos below)
Our budget is fairly low. I think a professional re-plaster is probably out of the question.
Is lining paper a sensible option?
Are there any other products or techniques suitable?
The house is ~1920s.
Update: I've had a quote from a plasterer - £400 to have the hall & stairs fully re-plastered. I know it's hard without seeing the size, but does this sound reasonable for a short hall and stairs? It's also way above my budget though so any other cheaper suggestions or advice would still be welcome.
80% of the wall is passable. The plaster is fairly smooth although there are lots of little bumps. I'm assuming that sanding it down to remove bumps and polyfilla to fill cracks will be sufficient here. Followed by a normal priming process (50/50 paint/water).
Around 15% of the wall has worse damage. Bits of the top layer (~1mm) of plaster are missing. I don't think polyfilla will work here as I'd end up layering it over large areas.
Finally, about 5% of the wall has big cracks:
