Is it okay to plaster?

[semi-acoustic]

Hi all

I bought my house a few years ago which had an integral garage conversion and just needed a skim of plaster, on plasterboards and a few other minor jobs to be completed.

Before completion the owners decided to decorate and just put up some textured wallpaper to make it look nice, however, I dont know if they sized the plasterboard beforehand (I suspect not) and am now considering redecorating.

I am wondering can you plaster over the wallpaper which will undoubtedly be left on the plasterboards when I try to remove the textured stuff, I know the cheaper option would be to replace like for like but to be honest I would have got the boards plastered in the first place.

Any advice would be truly appreciated.

You can't plaster over wallpaper. I tried it years ago - what a disaster that was.

You cannot plaster over wall paper- full stop.

You cant do ANYTHING over paper, i have just quickly painted a kids bedroom, just to spruce it up and the weight of the paint and the moisture is bubbling and pulling it off.

I was skimming a living room a few months back, over rubbish plastering( which had been on a few years ). Right near the end just as it was hardening up, trowelling away and i pulled off my coat, the other coat and then the paper underneath that.

Waited a few days, and went back an there was some patches where the moisture from my coat had soaked all the way through to the paper.

So i got my scraper and after 25 min on the floor was my plaster, the old plaster and the yellow wallpaper, back to a solid surface. So had to do it again ( not at my expense )

But when i first looked at the job, the wall was ( multi ) hard as nails, nothing blown nothing cracked, just a rough finish like fine sandpaper. So only found out after.

Poxy paper.......
