Putty on chipboard.

[theswede78]

Hello!

I started renovating my hallway today. For the interior walls there, they have chosen chipboard which has been wallpapered over. I have now removed that wallpaper and am wondering if it's possible to apply filler on this surface, considering that the wood moves due to humidity. Will this lead to cracks in the filler?

Grateful for any answers.

You can fill with acrylic filler as far as I know, but it's expensive as poker. Renovation plaster? DON'T know, but I've heard and assume that regular filler adheres poorly to wood or, as you say, cracks over time.

As it stands now, there are a lot of wallpaper remnants still on the wall. So the filler will probably adhere to that. It's mostly the cracks due to the movements in the wood that I'm worried about. How much does a particle board actually move?

Another problem might be that the water in the filler causes the wallpaper remnants to come off. Or well.. problem and problem, but just so you think about it.

A chipboard probably doesn't move that much, I would think.

plaster instead.. all wood moves and cracks appear in the wallpaper.. I have been stingy myself and have to redo it

Another issue that might occur is that the water in the filler causes the wallpaper remnants to peel off. Well... issue and issue, but just so you're aware of it.

You should be able to avoid that by first applying an oil-based paint as a barrier.

If it were my wall, I would probably apply a layer of gypsum instead.
(Cheap gypsum from bauhaus or byggmax might not be much more expensive than oil paint + a lot of filler.)

Install with staggered joints compared to the chipboards in that case.

I've decided now. I'm putting up repair fabric. I have a few strips left from when I renovated the living room. The thing is, the wall is only 178 cm long and 79 cm high, so it's probably made of particle board.

Thankful for all the answers.

It should be fine to putty on chipboard. The movements within a board are negligible, and the elasticity of the putty absorbs it. The boards can move internally, and at the joints, paper strips should be puttied in. All the interior walls in our house from '66 are made with chipboard and joints puttied with paper strips, and there are no cracks anywhere. I have wide puttied on wallpaper with regular sand putty on several walls, and it works well.

In all new Älvsbyhus, wallpaper is applied directly on particle board, no problem!

I also have chipboards and there's no problem plastering on them and the wallpaper is still hanging after 33 years.

I have wallpapered directly on particleboard, leaving only a small gap between the seams and applying joint compound + tape on it.

Another important thing to consider is to prime the particleboard before wallpapering either with wallpaper paste or regular primer to ensure it is saturated.

I personally chose a slightly thicker wallpaper due to movements in the timber
