I'm decorating my front room. When I removed the wallpaper in the
bay, in places the top surface (ie no more than 1mm) of plaster came
off with the wallpaper. What's left behind is sound.

The house was built in 1912 and I think the existing plaster is lime
based (it's a creamy with animal hair in either the finish or undercoat
plaster). I'm planning to put lining paper up & emulsion it, but when
I tested it with a bit of lining paper the unevenness showed through.

Unless anyone's got a cunning solution / product I guess I'll need to
skim it. I haven't skimmed any more than small patches before, but I'm
prepared to give it a go - so any top tips would be very welcome.

What I don't know is if I can use modern finishing plaster on top of
lime plaster? I know that the purists answer is no - but what I don't
know is how dodgy it would be? If it means it would last 30 instead of
100 years - I can live with that. If it means I'm likely to have to
re-do it in 6 months (bearing in mind there's been movement at some
time in the bay) then I might as well do it properly.

Thanks,

Michael
