Have to hang a TV on a plasterboard wall, will this do?

Look Loyatemu thought on it for a second and has presented a solution - 2 mins in B&Q looking at fixings would present 10 more.

That solution was literally what the OP didn’t want to do. And I agree with him, it would look messy.

And as others have pointed out. There’s no magic fixings that will do this. A flush mount, sure not a problem. But a fixed mount is basically a big lever prying the fixing out every time you extend it.

There are loads of options if your anyway practical minded.

Most he has to make up is 20cm

There are options that involved doing it properly with proper support. It's not that big a deal.

But I can't think how picking up a fixing is B&Q is an option. But by all means, if you can share away.

You don’t know that, your making an assumption about the build. Maybe it’s a wall some DIYer closed up.

it's going to be under the mount, and behind the TV. Paint it the same colour as the wall and it will barely be noticeable.

These are the options from what we've been told

1. screw into a stud - X no studs available at that location
2. screw into solid wall behind - X there's no solid wall behind
3. use heavy duty hollow wall fixings - X they won't support a cantilevered mount
4. screw some wood between the studs - X too messy
5. cut a hole in the wall and reinforce it from behind, then re-plaster. This also sounds pretty messy but it's the only one left.

For a fixed bracket, it’d be cover. But an swing arm will leave it visible. If your going to do it, do it right imo.

5. cut a hole in the wall and reinforce it from behind, then re-plaster. This also sounds pretty messy but it's the only one left.

That’s the option I referred to above. It’s a bit of extra work, cutting/patching. But shouldn’t leave any mess or be visible.

If it's a stud wall Option 5 is the only long-term safe option for this.
Find the studs, use a stanley knife and a pad saw, remove a portion of the plasterboard. Mount a proper grounds, replace plaster board, tape and joint.
I've done this numerous times at home now for TV's, extra kitchen presses and vertical rads.
It can be messy, but once it is filled and painted it isn't noticeable and hanging the bracket is easy

A foot? Not quite. Standard spacing is 400mm. But many modern extendable brackets have a single line of fixings. So there’s not much lateral adjustment
And even if the bracket is a foot wide. The fixing points may not land on studs. Aligning them means it’s off centre.

L

The fixing points should land on a stud as that’s what you mount them to. The TV can then slide along the rail. I.e the bracket doesn’t have to sit Center behind the TV. So no it won’t be off center

Here’s a bracket. Lots of holes to allign with studs. And room to slide TV to Center on wall

OP, assuming its a stud/partition wall, whats on the other side?

You dont need to cut open the wall on the side you are fixing to, you can do it from the other side just as easily (and often that other side will be in/behind a wardrobe etc and so your plasterboard patching skills dont need to be top notch.

If its just plasterboard over concrete/block wall then just frame fixings and dont even worry about the plasterboard.

I guess basically we need more info before we can offer an more suggestions

It’s an extendable arm that’s been spoken about here for the mount.

And being extendable it means it’s hinged so the wall fitting doesn’t need to be Centered. Personally I’d never use a single arm. I’ve linked to an extendable one previously that I recommend.

That looks like a good bracket. I've used similar types in commercial projects.
But the OP said he has a single arm bracket, if he is willing to buy a different bracket, that's an option.

okidoki987

He said there was no studs in that location, not there there were no studs in the entire wall.

The fixing points may not land on studs. Aligning them means it’s off centre.

Spot on.
As it needed to be in the middle of the wall, it was going to miss any studs.

OH has now decided she doesn't want it on the original wall as space was too tight for the TV and didn't look great so going to hang it on an wall
that has plasterboard and brick so much easier.
Will just use concrete screws which should do the job.
Thanks for the suggestions.

Ignoring the part where it’s going on a different wall the above isn’t right.

The bracket doesn’t need to be in the CENTRE behind the TV. Especially if it’s on a arm. So you can use studs and still have the TV in the middle

It's a small wall (30" in total) and TV needs to fold it in after use and because it's between a patio door and window, easiest way to fix it is mid point on the wall so the the TV folds back into the wall and doesn't obstruct the window or Patio doors and fits into the corner.

When it's up and working, I'll pass your thoughts to the OH but if I let her read all the comments/thoughts/suggestions etc on here, my brownie points will be zero. .
Yep, amazing the number of different suggestions from different posters.

I absolutely agree and if I had my way, one of you could put it up for me her .

I've used four blue GripIt fixings to fit a 32" television and bracket to plasterboard wall over two years ago now and it's still there,
Each blue GripIt is rated to 80kg



Here's an example of how they work,
Flat heat screwdriver push in and twist; to spread the wings at the rear of the plasterboard,





Four blue GripIt fixings fitted, rated at 80kg per fixture,

The Key to the Question is the Extending Arm!

To calculate the weight on the tip of the arm multiple by 5, TV 14kg + Arm 5kg X 5 = 95kg on the tip of the arm. As previously said the fixing will hold but the plasterboard will not, of course this depends on the thickness and how its fixed to the wall.

Option 1: use a fixed bracket

Option 2: cut the board and get back to the wall, fix timber to the wall and the bracket to the timber

They still rely on the strength of the plasterboard, which isnt 80KG in many, many cases.
(especially when you install them so close together as in one of your pics! :eek:)

Any crack or tear in the paper or dampness and the TV is on the floor. (Probably still attached to the bracket which is still attached to the plasterboard, so the fixings didnt fail, the plasterboard wall did)

Valid point, I see what your saying.
Would be a big job with a stud finder and a Stanley knife to locate the neighbouring Studs, then cut out some plaster to Fit an additional noggin (horizontal section)

Its actually not that big of a job tbh, most of the issue with plasterboarding work is trying to blend in the finish, in this case thats not terribly important since its going to be hidden behind a TV.

In some cases I have just screwed a rectangle of 1/2 or 3/4 inch ply or mdf across two studs (surface mounted) and then painted to match the wall, you can then fix the TV where you want and unless someone is standing beside it they wont even notice, and even then I'd argue that a painted to match piece of timber is no worse than the arm and associated cables.

In a small alcove/space like the OP has I wouldn't give it a second thought tbh!

small hole and some wire will find the stud in a minute.

If its still their fair play.

Would never hang in anything not solid myself

Fine Cheers

Will be doing something similar myself this weekend once my bracket arrives from Amazon Spanish Branch.
Another way of possibly locating studs is check for nail heads in skirting.
Took me ages to source a bracket that can go around corners:
https://www.youtube.com/watch?v=mzkCeu_WEZA
Timber frame house so will be locating stud also. 32" tv so not mad heavy.
Did a bigger one for kids and did as previously suggested - small piece of ply to bridge 2 studs, painted in, grand job in bedroom.

Not really. The sole plate runs the length of the skirting.
I guarantee nobody fitting a skirting reaches for a stud finder first

DublinDilbert

Get a strong magnet and go over the wall, it will stick to the nails/screws in the studs.

why not. its the properway to do it.
if there is only 1 sole plate then its only 44mm at best and 30mm with some flooring. thats not enough to fix to on its own. you need fixings at the top to hold it in. a magnet is great for finding studs

Hi guys.
Interesting threat!

I hung our 43 inch TV on a swivel mound back in Dec. This one has 3 screw holes to mount on the wall.

The wall is plasterboard and concrete behind it. I used a stud finder and found the studs but the seem to be well back from the plaster board. The bracket came with a screw kit and spacifickly for plaster.

However 3 months on and the tip screw and plug are starting to come away from the wall. The other 2 screws are still solid in the wall.

Just cansious that it may at some point come crashing down.

Any ideas how to resolve this with out recking a recently fresh painted wall?

Pics attached

Thanks

Surely all of the weight is acting on the top screw in that setup? Looks like a terrible design to my uneducated eye.

You say you found a stud? Why did you put a wall plug into a stud? Is this common or have I been doing it wrong every time?

ted1

Is it an insulated plasterboard? Or how are the studs so far back. If they are far back , where the screws long enough to reach the stud and go into it?
Looks like you just mounted into the plasterboard.
What kind is stud finder did you use ? Could it reach the depth ?


I’m not a fan of single arm brackets

Sorry but I am confused by your post.

Is it a stud wall or solid wall?

Plasterboard might be insulated board, 30mm + insulation.

Simple solution is screw in bolt 100mm long or as long as needed. Bolt type based on stud or solid.

My walls all have 52mm insulated plasterboard over a mix of solid and stud walls. All mounts bolted in, I could swing from them.

loyatemu

It would be useful to know what kind of fitting they supplied for use on the plasterboard.

As others have said, with the TV extended out from the wall, there's a lot of weight on that top screw. Some of the better plasterboard fixings are rated for surprisingly heavy loads, but when it's all concentrated on a single fixing, the issue is the strength of the plasterboard itself.

The boarder

Yeah that makes sence. I think I'll just replace the backet with a better one. Found this one on amazon which looks a better fit. That combined with a specialist raw plug for plaster boards weight rating. should do the trick.

https://www.amazon.co.uk/dp/B00N50Q66Y/ref=cm_sw_r_fm_apa_fabc_BH18YB5WRNRFC56504NZ

From this I don't think the single arm brackets work well for my situation. But we live and learn.

Just fix it to something solid instead of wasting cash on another bracket surely??

Plasterboard plugs might have great capacity but nothing to say the board they are in can handle it.

2 bolts into something solid = forever solved.

I had a similar issue when mounting a TV to an external wall. There seemed to just be a cavity behind the plasterboard and no way of reaching the brick exterior and studs were nowhere near where we needed? Very odd, I thought.

Managed to secure a single arm mount for a 32" TV which is going find (although we're careful when adjusting). When we upgrade we'll need to rethink the approach.

Cavity blocks are common, there are bolts that are designed to go in and catch which will do the job - head goes through - expands and then catches on inner of block.

Sorry maybe I didn't describe it well enough, but there was literally just a space of air behind the plasterboard and any brick was too far to feasibly reach with any screw or fixture. I put enough holes in the wall to be sure! Whenever we upgrade through the TV location will change slightly so we may have more look then.

wex96

You need a wider wall bracket that'll take 6 screws, zip toggle fixing are strong.

Interesting. Piece of threaded steel bar threaded into the wall behind? Only a few quid in B&Q or similar. Just a thought.

salmocab

It’s been mentioned a couple of times but worth remembering that using plasterboard fixings the real risk is the plasterboard failing not the fixing.
If a fixing is rated for x kg and the tv ends up on the ground the chances are the fixing will still be intact and attached to the bracket and there will be a big hole in the wall.
Also a tv that is on a wall is pushing down on the fixing whilst one on an arm is pulling the upper fixings.

It's gotten to the stage now that tv bracket manufacturers are including a link to this thread in their installation instructions.
