Joint compound between drywall and chipboard

[Dennisen]

Hello!

I have removed a doorway where the wall is made of chipboard, and have framed and closed up this opening with a plasterboard. There is a small seam around it, and I would appreciate some tips and advice on how to proceed smartly now!

Can I just apply filler and skim before painting? Or is there a very high risk that the filler will crack?

Should I apply filler, then renovation wallpaper on top, and then paint?

Or is there an even better way?

A novice who gladly accepts tips, thanks!!

Plaster the entire wall.

It's possible to apply paper tape and putty, but what was the reason you didn't remove all the drywall up to the next long side seam?

You can probably apply paper tape and plaster, but what was the reason you didn’t remove all the drywall up to the next long-side joint?

Hi Bygges!

The reason is that the walls in my house are chipboard, built in 1981!

So what happened was that I removed the door and replaced it with drywall, today I used a tape and plaster, and I am satisfied with the result!

Hi Bygges!

The reason is that it's particle board walls in my house, built in 1981!

So what I did was remove the door and replace it with plasterboard, today I applied a strip and filler, I'm satisfied with the result!

Aha, I thought it looked like plasterboard next to it, but it's actually filled and painted particle boards?

Exactly! It's a wardrobe, it's particleboard then there's probably some paint/wallpaper on it simply

Here is the other side:

Absolutely! It's a walk-in closet, it's chipboard and then a little paint/wallpaper on it, simply

How did you do it and were you satisfied?

Hello! Yeah, I think it went quite well, I used a kind of "mesh" in the seam inside the closet because I wasn't going to put wallpaper there, so I applied filler over the mesh and then sanded and painted.

In the hallway, I filled the seam and then put renovation wallpaper on top, you can glimpse where the door used to be if you look "actively," otherwise it's not something you notice!

Then in the closet, it's slightly more noticeable, but it doesn't matter to me!
