Repairing holes in the wall

[90rammar]

Hi, I'm wondering how I can best restore this hole in the wall where a fan has been located between the living room and the kitchen.

Seems to be hardboard. Buy a hole saw of the same diameter and cut out these circles in hardboard or another board of the same thickness (renovation plasterboard can be a suggestion). Glue some support over the holes on the inside, e.g., a wooden strip. Screw it to the support and glue the edges with wood glue. Spackle.

If you don’t want to repaint, buy vents with discs and install them in the holes.

Thanks for the great tips,
Is it okay to just glue the support or should it also be screwed into the wall?

Easiest - doslock.

Okay, simple is good, but I'm planning to put up wallpaper in the room so it would be nice to restore the wall as well as possible before, I thought.

Yes, it's probably wise to drive a screw into each end of the support, otherwise it would be difficult to secure it just by gluing. But with today's good mounting glue, it might be enough to just press the supports in place (if you have that kind of glue at home).

In that case, I wouldn't have cared at all. If the wallpaper is of the more modern, slightly thicker type, it's probably enough that the seam doesn't come over the hole. If it shows afterward - doslock...

Sounds good, do you think I can use regular drywall screws even though it's hardboard, so that the screw pulls down into the material making the plastering better?
