How should I handle old drywall with wallpaper remnants?

[ejkunnighusägare]

Hi! Our house is from '67 and I've stripped down like 67 layers of wallpaper. As you can see in the pictures, the wall looks pretty dingy, with some wallpaper remnants and some old putty left, but I've paused the work because I'm not sure if I'm just working myself into a corner. The surface is relatively even, but I think unevenness will show through a renovation wallpaper. Right now I just want to tear down all the old drywall and put up new ones, but it's hard to manage that at the moment. How would you handle a wall like this? We want to get a smooth surface and paint it The options are probably renovation drywall, using wide putty, continuing to remove wallpaper, and then applying renovation wallpaper. Thanks for the tips 🙏

I had sanded down all the old wallpaper tabs that were sticking out, painted with stop color, and applied a broad layer of spackling.

I had sanded down all the old wallpaper seams that stick out, painted with blocking paint, and applied a skim coat.

Okay, great thanks!
Now my partner “primed” with wallpaper paste instead of blocking paint )))) is it possible to prime over it? Or do you need to handle it in some other way? Or does it function like blocking paint too?

Wallpaper paste dissolves in water. You can't use it as a base if you're going to use wide filler. You need to paint with a blocking paint (I probably wrote stop paint in my previous post).

Why did she paint the wall with wallpaper paste?

Edit: No, it won't be good to paint the wall when you've first used wallpaper paste on it.

Wallpaper paste dissolves in water. It can't be used as a base if you're going to do a skim coat. You need to paint with a primer sealant (I probably wrote blocking paint in my previous post).

Ok! No, she simply made a mistake, took the wrong can when I wasn't home but okay, so then you kind of need to wash off the glue first? 🫠

Yes. You need to wash off the glue with wet sponges.

But it looks like you have asfaboard as the bottom layer, right? It might be easier for you to just take them down and replace them with a new base. That way, you avoid having to remove the wallpaper paste. Also, the walls from '67 might smell a bit bad, and you can check the insulation at the same time.
