I have a couple of holes in some plasterboard about the size of a 10p piece which I want to block up. However I still want to maintain the cavity behind the board (its attached to batons on the wall behind, so filling it with expanding foam or plaster is not an option. I ned to bridge the gap with something to provide some structure, fill in then skim over. Anyone aware of any products out there that I can use or any methods I can use?
The reason I want to maintain the gap behind the plasterboard is that it is a newly build extension and the builders installed some conduit behind the plasterboard so I can route speaker wires behind the wall. The holes were made at the exit of the conduit, but the are in the wrong place as I wasn't specific enough with the builders about their positioning. If I were to just fill in the cavity then it would render the system useless as I would no longer be able to route wires easily behind the cavity.
I was considering trying to glue some mesh or something behind the board, but this seems a bit fiddly and not sure how strong it will be. The other option I considered was to try to hammer some thin tacks or screw in some thin screws into the plasterboard to bridge the gap, or partially bridge it, and hope that that will be enough structure to hold some filler or plaster. Anyone with any better ideas or methods?
10p? I would have thought you would get away with just wapping some filler in and build it up over a couple of goes.
Yep, about a 10p, but not circular, but in terms of the span about the diameter of a 10p. I thought about building up the edges as you say but don't want to be in the situation where it gets pushed out further down the line if someone leans on the wall or something. Do you think filler would be strong enough especially if I taper/countersink the sides?
Cocktail parasol
No more nails
Polyfilla
Sandpaper
Paint
No one will ever know...........
Like!
Forget my suggestion thats actually brilliant!
It's a good idea, because it gives you great reason to get sh1t faced on wired coloured drinks with fruit in them.
Love it alex. Its ideas like that that built this nation! I might just give that a go, i'm sure i've parasol lying around in a drawer somewhere,and i'll make up a Brandy Alexander for the sheer hell of it.
Do it after thou, or you'll make a right mess of it! Use some masking tape to hold the cocktail stick thing Central whilst the no more nails drys. This is the time to make your cocktails, hopefully you'll of thought ahead and put ice in the crusher and opened the vermouth to 'breath' by the time you come around (in my case a day or two) the whole thing should be solid. Slightly trim the paper of the plater boards as you said in a taper, it'll prevent roughing it up when you sand flush. When your done, pour yourself another drink.
Good luck, but stay off the 'harvey will bangers' *boom* *boom*
Scrap piece of plasterboard, holesaw slightly bigger than the holes. Enlarge the holes, cut new pieces, glue in with no more nails solvent free, wet edges first. Gripfill won't stick properly, fill over and lightly sand flush
I was going to suggest a bit of cardboard from a cereal box, use a needle to stick a bit of thread through the centre and back out again. Push cardboard through hole and then use thread to hold against reverse of plasterboard.
Then apply some filler (I'd use plasterboard jointing compound as its very easy to sand, but it only comes in huge tubs), let it go off, then snip the thread and do your 'finishing' layer before sanding.
You could so that, but weatabix isn't as much fun as booze now is it.
I used to make a little device with piece of cardboard with a string through it, and a dab of plaster. I will now be using cocktail umbrellas 🙂
😀 ...got to do one soon a well
