DIY Advice

I need a temporary fix. I have the hole in some verbally, fixed chipboard into which were hinges were screwed to hold a cupboard door.

I thought the baking soda/superglue trick would work a treat as I could screw into the plugs of the set mixture and they’d be strong enough to hold the door (there are six such hole). But of course the holes are in a vertical piece of chipboard. Any suggestions as to how I can pour baking soda and then very fluid cyanoacrylate into the holes without the former just pouring out? It doesn’t have to be neat looking.

There are YouTube videos on this. You will need to use a straight edge to draw a square around all of the damage, and then cut the square out. Then you take that square, and trace it onto a new sheet of drywall, and cut that that out. You put the new square in, following the instructions in the video using the plaster.

Not sure i have the skill to do that accurately enough, hence the NaHCO3 and superglue!

I’ve made a sling with Scotch tape around the hole and filled it with bicarbonate. Now I just need to dribble some superglue into it.

Any reason you’re avoiding using wood filler? Some wood fillers would probably be stronger than the pressboard.

If it’s a bigger hole (hard to tell how big that is), I’d probably use a dowel. Drill it out, tap a dowel in kind of like a cork with some carpenters glue, saw it flush… give it a quick sand.

I'd have a couple more questions -- but that's my first thought, as well. The big question is whether he intends to remount whatever pulled out there. If he does -- patches won't work; they'll likely pull right out again. That means replacing the section, not just filling the holes. Not really hard, but it does take a little bit of know-how.

If he's just trying to fill the holes... Wood putty will do the job, but I might use some tape on the back to minimize what pushes through. You just need enough to help hold the putty. Push the tape through so that the sticky side is facing out (even easier if you can get to the back side and don't have to play with sticking tape "inside" a box from the outside...

Honestly, if it's cupboard door... Long term, it's replace the chipboard crap.

Edit: Just re-read the original. If he's going to try to rehang the door... filling the holes is unlikely to work. The holes are concave and the fill will essentially make a plug that'll just pop out under stress. There are ways to patch it and have it hold, but it'll take some work and need some skill. It really takes a replacing that section or the entire door.

You could probably do it with epoxy resin with some of that brown filler stuff mixed in with it. No fuss or complicated stuff, just mix it up then apply and smooth off with a scraper

Now do you see why I say that chipboard is a form of violence inflicted on the proletariat?

Ah yes! B&Q here I come!

Just make sure to get the proportions of hardener and resin right

Agreed. Though it’s worth noting that modern wood glues can create a bond stronger than the wood itself. Meaning that if done correctly and with proper glue, the door will fail elsewhere before the plug fails.

They can -- and have been able to for years. Elmers used to have an ad for their wood glue when I was a kid that featured them gluing a diving board together. But in particle board like that, you just can't get a reasonable bond to have it work.
