Wall with plaster-wallpaper several layers of paont

Question

Hi,
I’ve got walls in my house where the wallpaper has been put on the plaster without base coat. On top of the wallpaper there are several layers of different paints. Can I sand this down until the plaster, wash it with sugar soap and than apply a new layer of paint? Would that work?

Michael · Accepted Answer

Yes, the entire wallpaper needs to be removed and the old paint stripped. Then, the holes should be filled, filler applied, the walls leveled and sanded. After that, wash the surface and apply a mist coat, followed by two coats of paint.

Yes you can it might be worth  taking  off wallpaper  with a wallpaper  stripper

Hi There 😊
In my opinion the best way to get back to the basic wall is to steam strip the wallpaper along with the layers of paint being done previously. Also be aware that might have some imperfections and cracks here and there after stripping so it will need some repair works before new painting 👍🏻

The simple answer is  yes !
Make sure use a high  fought grade paper and reduce the grade of paper to as fine as you feel fit for the finish,

You can sand it down, but you don’t need to get all the way to the plaster. Just sand it smooth, wash with sugar soap, then apply a good primer,undercoat before painting. That should work fine.

You can sand all down but there might be damage to the plaster. 
You will need to sand the plaster too and then apply a mist coat and then wait for it to be fully dried. 
Then you will need up to 2/3 coats of paint for the wall to look the best

Good morning, without seeing it, you’ll need a nice steamer, a good scraper that doesn’t mark the walls, sand back and repair with filler etc. 2 coats of undercoat/primer top colour dependant.
Regards

No you need to remove paper, you'd be there for ever trying to sand through wallpaper

Lukas · Answer

Sanding won’t cut it. You need to strip the wallpaper + paint off, clean and prep the plaster, seal it, then paint.

Stephen · Answer

Just strip papers, smooth off then paint over.
