Best raw plugs for 9.5mm plasterboard

Tim Robbins · 12-11-2023 9:07pm #1

Hi,

I have one wall with 9.5mm plasterboard and 20mm insulation so in total 29.5mm warm board.

I tried a few IKEA raw plugs that worked 12.5mm plasterboard and they are not really gripping well.

Any suggestions what to use?

Thanks

What are you fixing to wall?

windowcills · 12-11-2023 9:24pm

Keep going till ya hit concrete, then go another 2 inches

Then get a big long rawal plug, you can get then 8 inches long in woodies, essential for curtins and tellys

Bit mad if its just a painting

Sonos speaker one.

Looks like under 2kg

For peace of mind I would either find a batten if its battened to the wall or go into block beyond the insulation.

How many fixings does it have?

If it has 2 or 3 then I would be pretty comfortable using these for that weight, though many people don't seem to like them, I have never had a problem with them.

Horrible horrible creation.

These are very good. Using them for years in both plasterboard and concrete. Red are 6mm and the brown are 7mm.

I recently discovered GripIt fixings. (soz, cant post pics) . I put up brackets to hold a heavy shelf, and very happy with them. Loved that they dont need to go deep past the plasterboard in order to spread out. The surface area of the hole they make is quite big (about an inch) so not ideal for some situations.

....well, lets try post a link

I've used these for a few years now hung everything from 65" tv's, curtain poles to pictures and speakers can't recommend them high enough

Bullfix from Screwfix. Easy to fit to insulated plasterboard and will take massive weight. Fairly full proof to fit. In comparison tests they do far better than Gripfix.

Used them everywhere, but will be using them to fix concealed bracket scaff plank shelves into insulated plasterboard - absolutely certain they will not let me down.

I used to use them over 20 years ago and found them to be brilliant. (I haven't used them for at least 15 years as I reskilled during the recession, I used to work in construction)They hold far better than a red raw plug someone posted after your post. Raw plugs hold great in concrete but a raw plug by itself into plaster board will hold nothing.

Very limited carrying capacity and they pull out easily if you overtighten the screw in. I use them a lot but only with minimal load.

awec · 13-11-2023 4:13pm

You say you're using Ikea raw plugs, are you sure you're using the ones designed for plasterboard and not the ones designed for solid walls? The ones for solid walls won't work in plasterboard.

Are you definitely drilling the hole the right size?

The speaker you're hanging is less than 2kg, it's very light. You shouldn't need any of the more elaborate fixings for this.

loyatemu · 13-11-2023 4:17pm

Gripit won't work in the situation described in the OP as there is no cavity behind the plasterboard, just more insulation. I don't like those metal screw fixings either, in my experience they crumble up the plaster and leave a massive hole.

13-11-2023 6:54pm

Bullfix just eats into the insulation but doesn't damage the plasterboard. I have used them to hang kitchen cabinets.

tred · 14-11-2023 2:21pm

I have used the fischer Fixings ,but you need the fishcer mounting pliers to engage them. I can vouch they work very very well and can take weight.

I have a similar wall construcion as yours, I use the corefix fixings, they are especially good for heavier objects but they are bit expensive.I have used them for TV's, shelves, and heavy curtain pole/curtains.

They look good when you are dealing with dot and dab. My warm board is attached to wooden pillars every foot or so which are then attached to wall.

I got hallow wall anchors https://www.diy.ie/departments/fischer-steel-hollow-wall-anchor-m6-l-52mm-pack-of-4/1639069_BQ.prd

Drilled an 8mm hole put these bad boys in and so far so good

Exactly, a rawl plug in plasterboard might as well be a nail. The ones I linked are effectively large screws so have pull out resistance, which is what you want in plasterboard.

If you over tighten them they will just burrow through and keep going but if you use them as they are designed they work very well.

Granted the hole is bigger than a rawl plug would leave, but its no harder to fix so I dont see the relevance tbh.

Great short this.

Tim Robbins · 10-12-2023 10:38am

Folks, for anyone reading, I ended up using: Diall Self drill Plasterboard Cavity plug (Dia)13mm (L)32mm, Pack of 25 | DIY at B&Q they work well when there is a gap between you warmboard and your brick. They do not work well when the warm board is attached directly to the brick which is the case usually in the window reveal. I have a separate thread on this situation here: Putting up roller blinds in the reveal - Help — boards.ie - Now Ye're Talkin'

TheSunIsShining · 10-12-2023 10:47am

As someone said above, 2kg is actually very light. Almost any option, provided it is designed for plasterboard, should work for you

Was about to recommend these, the IKEA ones are horrible in comparison.

"I have used them for hanging kitchen cabinets".

Sweet Christ, I've heard it all now.

Look at the load carrying capacity.

I was going to scoff, but there are specific plastic rawlplugs for kitchen cabinets.

https://rawlplug.ie/products-filter/?rwl-tags-ch%5B%5D=domestic&rwl-tags-ch%5B%5D=Kitchen+Units

So yeah, as long as the pull-out force is satisfactory for the design load and not just the sheer rating, they should be fine.

Pages 28 to 37 are interesting that the respect, if that floats your boat:

Bullfix will far exceed the Raw plug offerings. Here's a vid of load testing, though I can tell you that the extra big Bullfix do not work in insulated plasterboard since the legs will not fully open, the normal size hammer open nicely though.

I wouldn't trust ANY fixing in plasterboard to hold up something that people will be interacting with.

Its one thing to hold a static load like a TV, its another to hold something that people could load with all manner of things and will have people pulling out of doors etc.

I'd agree with this 100%. Load carrying capacity is fine, but doesn't always take into account the the capacity/structure of the plasterboard wall. I've seen cabinets fall down, taking a full sheet of plaster board down.

Regarding that Rawl Plug document, there seems to be only 5 mentions of plasterboard from p 264 on, with some fairly poor ratings in comparison to concrete.

Hanging cabinets it wouldn't be too hard to find grounds or even fit bridging pieces!

10-10-20 · 14-12-2023 1:58pm

Sonos speaker one on plasterboard was the original objective of this thread... we have diverged into kitchen-cabinets hanging off plasterboard... which I think I missed in the text just above... doh!

I'd never be hanging kitchen cabinets off plasterboard, solid wall or wooden uprights only. Sorry if the confusion came from my side.

He uses 4 fixings on a small piece of plasterboard, with the fixings mounted perfectly between the two joists and carefully places a load on top, and they still fail. These seem perfect for certain types of fixings, but I wouldn't plan on using them for large installations such as kitchen cabinets as GreeBo states.

I always find these sort of fixings loosen over time if the unit\appliance is in constant use, doors opening, stacking stuff etc.

GreeBo · 14-12-2023 3:58pm

If you cant get a French cleat to work on a cabinet wall you shouldnt be putting anything on the wall :D
