Will I pull the wall down?

I'm thinking of using the fitting which spread out in a X shape as you tighten the screw. Should I put a thin sheet of ply between the bracket and the wall and use additional fixings?

Depends how the plasterboard is mounted to the main wall. Battoned every 6-9 inches and studded properly with screws, it shouldn't be a problem. Likewise if studded with a generous amount of plasterboard adhesive.

You need something like these to mount it....



Fischer Spring toggles. Drill hole, collapse spring, push through, tighten up.

Just mounted some heavy kitchen cabinets to a stud wall using these, they aren't going anywhere. Not expensive, get something reasonable like 50-80mm though, just to make sure.

I recently used these to mount kitchen units to a plasterboard wall, rock solid and I don't expect them to come down anytime soon - cavity wall anchors, the sleeve bends in the middle and draws towards the back of the board as you tighten. Benifit of these over the spring toggles is you can take whatever you're mounting up and down until your hearts content, with the spring toggles once the fixing is through the hole if you need to undo the screw the toggle part falls down the back of the cavity and you need a new one!



Edited to add: I think these are the fixings you talk of in your OP, if so, yes, they should work fine.

I put a 32" TV on my wall but put batons across the upright beams to support it as it would have been too heavy. A 22" will be fine using the above suggested method.

As has already been said, the first suggestion will not work correctly if you wish to remove the tv from the wall.

I had a 32" plasma hung on a plasterboard wall, fortunately it was kitchen units the other side so i used some big coachbolts and some big diameter washers either side.

Hung there for 2 years with no problems.

Plasterboard is stronger than you think - the weight is directed downwards, not forwards.

However I'd put long screws into the timber uprights behind - strong as a house (literally!)

I've got a 42" hung in the bedroom, just found the studs behind the plasterboard and screwed straight into them. It ain't going anywhere biggrin

Spring Toggles are the easiest to use, that's if you can't pick up on a stud. Used them hundreds of times on hundreds of screens.

Can i ask how you located the studs behind the wall?

i want to mount one in my bedroom but am unsure how to locate the wooden things that run behind the plaster board.

You want some of these, much stronger than the other screws shown.

ETA: I have these holding up heavy shelves and a mountain of a mirror, not a hint of them moving.

Use a stud finder, emits a ultrasonic pulse? Is that right?

Yeah, about £15 and looks like a staple gun, good for finding pipework and wires as well.

I just tapped the wall, it sounds a bit different. They are usually on 16" centres IIRC. You can also use a bradawl if you don't mind making a few small holes. paperbag

this would depend on what type of hanging bracket your thinking of using

LCD's aren't very heavy so shouldn't cause much of a problem,
however if you intend hanging it with one of those adjustable brackets which pull out from the wall and then swivel/pivot in different directions I'd say it's not a good idea,

these types of brackets tend to cover only a small area when fixed to the wall which will increase the load and extending the bracket will only make things worse,

so your pretty much limited to the large flat brackets that just tend to tilt but will spread the load evenly across the wall

this type of bracket should be fine and as long as you use a suitable fixing (the ones shown above are all fine) and will last for years

plasterboard will take a fair bit of weight as long as it's well distributed.
I've hung large radiators on plasterboard walls before without any problems arising, so a LCD tv should be a walk in the park

having said this it's always best to fix to something solid and I always consider fixing to plasterboard as something of a compromise as unfortunately the solid bits aren't always where you want them to be

if your TV doesn't have to be in a specific spot as mentioned you could try finding a stud to fasten to,

a stud finder will do the trick or you could always try HRG's method biggrin

even if you only hit one stud and then have to rely on fixings for the rest it will make the bracket more secure

basically all you need to remember is try and spread the load as much as possible and you'll be fine thumbup

It does rather depend on the joiner who built it. wink

Remember that there are come types of plasterboard partitions that don't have studs in them (eg. Paramount and Stramit), in which case you ain't gonna find a stud no matter how good you are at tapping or how much you spend on stud detectors. biggrin

My experience of stud detectors is that they are a bit flaky, anyway, but that's another story....

... but to answer the OP's question, you're loading the fixings in single shear and plasterboard is usually a lot stronger than people give it credit for, providing the loads are static. You should be fine with heavy duty toggle fixings.

You've been lucky, they are not suitable for heavy loads.

Large spring toggles are the easy way out for a smallish set, but if it were my expensive TV i'd be cutting a section of plasterboard out and putting timber in behind it.

Because it's a huge generalisation and you're wrong wink

If you can find two studs behind the TV position
Cut away plasterboard
Replace with Ply Board
Job done!

Alternatively, the umbrella type fixings are very strong, I've hung some pretty large rads using them and have never had an issues.
