Painting 'cardboard' wall

johnny182

Hello! We're redecorating our entrance hall and while removing the wallpaper off one of the walls we noticed that it was some sort of cardboard instead of plaster. The idea is to paint this wall but I'm not sure how I'm going to do that now. Should I plaster it first (not sure if it's possible because of said cardboard)? Or should I remove the whole thing and then plaster it? I'm not sure what's actually underneath. Any help is appreciated!

A cardboard wall sounds like a bodged repair attempt at some point.


Take it off and replace it with plasterboard.

Is it hardboard? Only about half a centimetre thick?

Take it off, replace with plasterboard and skim.

Virtually our whole house was done with it. I've not seen it in a house before or since! It's no good as you can put your hand through it, even when plastered.

It looks like plasterboard over studs. Not sure why the previous owner didn't just plaster it but decided to wallpaper it instead. You're right, Doozergirl. I think I'll just replace it with plasterboard and skim it.

Is this an external wall, or a stud construction thrown up round a cupboard ?

Drill a hole to see what it is. If its thick enough you could just use lining paper then paint.

Fairly obviously plasterboard on studs. Is there a reason for it being bent ? What is on the other side ?

I have no idea why they did it like that. Do you guys think lining paper would do the trick?

Is it Tentest? Used quite a bit years ago.

Just looks like plasterboard. If it's as solid as plasterboard then yes, just use a decent lining paper 1400 grade or higher at least and it will give a good finish.

Lots of places use plasterboard and just skim over the joints to neaten up.

If you wallpaper over it nobody can tell, paint would take a few coats to cover it though. It makes the whole job cheaper as you don't need a plasterer.

It's just cost-cutting.
