How should I fix a hollow drywall?

[Haas84]

We have a drywall between 2 bedrooms that is hollow. The previous owners had a rather large TV on the wall and therefore drilled a lot of holes that went through the wall on the other side and used some form of large metal plugs that expand when driven into the wall. To get them out, I had to enlarge the holes significantly to be able to remove them. In one of the holes, I was a bit careless and took some drywall with me.

The whole room needs to be patched up since there are a lot of plugs all over the room. Just filling these large holes won't hold for very long. The question is whether one can apply some form of mesh or something similar to reinforce the repair?

I hope you understand what I mean?

I'll try to take a picture if it's difficult to understand exactly what I mean...

If the holes are reasonably close to each other, I would have replaced the plaster there. Otherwise, there is mesh.

Or drill a slightly larger hole and insert a fitting piece, preferably made with the same hole saw (but without the center drill). It can be fastened using a long narrow piece of wood. Insert the wooden piece into the hole and screw it into the existing wall board - this way you get a "standard" to screw the cover into.

Plasterboard? http://www.gyproc.se/gör+det+själv/så+här+gör+du/reparera+skador/laga+hål+med+gipsplåster

The holes are probably about 10-15cm apart.
How do you "replace" the drywall around a certain area?

Bo:
That sounds a bit complicated

 

[Haas84]

That thing with the plaster looked smooth.
Should you sand down the wall a bit exactly where the plaster is attached so that it comes under the rest of the wall, so to speak? Won't the plaster itself be visible otherwise when you apply the filler?

Tip, next time you need to remove a metal expander, grab the outer ring with pliers and rip it off. Then push what's left into the wall instead. Less hole to fill.

was a long time ago I watched them, but hope they can help you.

How do you "replace" the plaster around a specific area?

Cut away the plaster in the area where the holes are. Take suitable "scrap wood" and screw it to the inside of the wall at the edge of the hole so that part of it protrudes. Screw on a new piece of plaster of the correct size to fill the hole. Fill the joint and screw heads with compound as with a regular plaster joint.

I usually go with a slightly larger drill, 8-10mm, to drill off the ring. Then push the expander into the wall.

If the wall is completely hollow between two bedrooms, I would remove the plaster on one side, insulate with Piano Ljudskiva, and put on new plaster. While you're at it! 😁

 

[Haas84]

Have now done a patch with mesh and filler and am now eagerly awaiting the result after the drying time is complete.
Was first tempted to cut out the plaster and put in a new section, but the holes are in a too awkward position to get a good piece.
We'll see how the result turns out. If it's not good, I'll have to rethink again.

How large a piece can you cut out and replace with a new one without having to replace the entire board?

if the wall is also completely hollow between two bedrooms, I would have pulled off the gypsum on one side, insulated with Piano Ljudskiva, and put on new gypsum. While you're at it! ��

Couldn't agree more with this, I hate paper walls.

But it's too late now that the repair is already done. Please get back to us, Haas84, preferably with pictures, so the rest of us can learn from your experience!

Is there anyone who usually screws a screw into the plug just a few threads so that the screw sticks out quite a bit? Then hammer on the screw until the plug has straightened out and just pull it out?
That's how I've always done it, and it works well, doesn't leave any gigantic holes

Is there anyone who usually screws in a screw into the plug just a few threads so that the screw sticks out quite far. Then hammer on the screw until the plug has straightened out and then just pull it out?

Not uncommon for the entire collar to pull in and thus make an even bigger hole.... At least my experience from some such attempts. I think, however, that molly is a necessary evil that just destroys.
