Plasterboarding

KinSt77

Hi, we have bought a new house and the living room ceiling has been papered then painted several time, does it need to be stripped before we plasterboard it and or has anyone just painted plasterboard with it been skimmed, thanks.

Underneath that 'wall'paper should be plasterboard. So the question is, what state will it be in after the paper is removed?

You can but try.

If the paper comes off without damaging the p'board underneath, you may be able to get the surface good enough to paint with just some sanding and filling. Worst case, it'll need a skim. But this should be straight-forward UNLESS the existing 'boards are damaged, loose, cracked.

If a plasterer declares that new boards are needed, then you should be able to over-board straight on to what's there - no need to remove the paper first. If what's there is in poor condition, it might have to come down first, and then new boards put up - the ultimate solution.

How new is the "new house"?

My guess is it's an old house with lath+lime ceiling. Papered to hold the lime falling apart.

You can paint bare plasterboard but the joins will need a skim to hide them and usually tapered edge boards are used to make sure the joins aren't proud of the rest of the board

And tapered edge plasterboard is only available in 2.4x1.2m sheets which are very heavy and a pain in the butt to put up. A job that should only be attempted with a muscled tall helper and some props.

1800x900mm sheets are easier to handle (just) if you are working on your own, but they only come with a square edge.

You need to find a new merchants, even B&Q sell TE 1800x900! . Usually find specialist boards are taper only though some suppliers do have the ability to order pallets of SE

It’s quite common to line ceilings before painting. Why do you want to remove what’s there rather than just painting it?

I stand corrected.

My usual supplier doesn't stock tapered edge in 1800x900, but then he will deliver free of charge even on small orders. His prices are also a lot more competitive.

Odds of the plasterboard underneath being good enough to paint are extremely remote. You're best off removing the paper and getting the ceiling skimmed.

Because of the light cast across a ceiling, imperfections are extremely noticeable. Even with a super flat matt paint. Get it skimmed and then paint it is my advice.

On wallpaper stripping use a paper tiger quite thoroughly and zinsser dif sprayed on from a pressure sprayer. It'll save you so much time stripping ancient painted wallpaper.
