Can A 42in Lcd Tv Be Put Up Onto A Plasterboard Wall With Hollow Wall Anchors?
I'm just about to put up a 42inch LCD Tv (28kg) onto a plasterboard wall, there aren't any convenient wood studs to put it onto, can I use Heavy duty hollow wall anchors to put the tv and bracket onto up on the wall? can the plasterboard take the weight?

NO! Wallboard can hardly hold a picture. You will have to cut out a small section of drywall and add some support.

Within a 42 inch width, I would make new holes in the bracket and attach to the studs.

Absolutely not.
you need to strengthen the fixing point in the wall. Fitt a patress inside the wall by cutting a hole in the plasterboard and feeding a 50×25 batten into the void. Fill the hole when finished and make good the decoration

Please forgive any assumed irreverence…NO!
BUT….. in a direct answer to any CAN I questions I always answer YES; and add; you may not be happy with the result.
Very recentlyI answered a similar Q and I posted a Link, to an aol handy man DIY site that offers advice regarding your Q.
42 inch seems to be extremely popular, and a viable size even in a smaller room. Have you not considered that bracketing should be at/in studs? I guess if you insist on attempting it; you might load the floor underneath with a bunch of pilows.

only if you want to watch it on the floor.
plasterboard will not support the weight.

Tell me if it works, why not try to use the studs be much better than wasting $1500 that you will find on your floor when it falls down

not recommended

install a piece of batten ( wood ) across the area you wish to hang the t.v. make sure it is firmly screwed into the timbers ( stud ) inside the wall.
Then screw the t.v. bracket onto the batten.
job done

Hi,
As many butterfly bolts as the TV casing allows, which spring open in the plasterboard cavity should be OK, as the weight of either two 14kg is not massive, and four seven kg points is not a problem
I would first tap the wall to find the dull thud of the supporting woodwork to establish where he noggins are, and pencil mark them.
If you are lucky, the more solid wood bits will tally with the mounting hole centres on the TV. Then you can drill small holes into the timber, and use as big as possible wood srews
Much better & safer.
You will need to make a decent sized hole in the plasterboard anyway, to feed the signal & power cables through
Feeding those neatly & internally back to mains & ariel / DVD sockets is a trickier task if you don’t want wall mounted pvc trunking on show.
One small advantage of having thin platerboard internal walls is that they are easy to attack & repair.
I was stuck with mounting one above the fireplace, so had to remove several bricks and fit a fireproof tube through to the garage. Nightmare.
All the best with it, then

I would not think so good luck with that

Can be done you just need the right fixingshttp://www.fischer.co.uk/befestigung/ver…
convert the Kn into KG
Fischer toggle clamp KD 3 holds a recommened maximum of 0.14 Kilonewton = 14.27 Kg force.
So 4 of those will easily hold 28kg.

Don’t use hollow drywall anchors. For such a high load the plasterboard will fail at the fixings.
Hopefully the plasterboard wall you wish to attach too is not that dual layer plasterboard with a honeycomb paper interior that is commonly used as a non-load bearing partition in the UK and probably elsewhere in the world too.
Its not so much that the plasterboard can’t support a 28kg load its more that its not easy to transfer that load so that it stays within the plasterboard core. Even if you manage to achieve that feat you then have to consider how to stabilise the plasterboard so that accidental damage shock and vibration don’t compromise the load. Oh and did I mention that if anyone leans on the television all that force will be trying to tear those hollow fixings out of the plasterboard..
DON’T DO IT!

WHAT YOU NEED TO DO IS MARK OUT WHERE YOUR TELLY IS GOING THEN MAKE SOME SMALL HOLES TO LOCATE THE STUDWORK ,THEN FIT SOME 18MMPLY ACROSS THE UPRIGHTS IN THE STUD , ENOUGH TO BE ABLE TO FIT YOUR TELLY BRACKET , THEN PAINT THE PLY THE COLOUR OF YOUR WALL FIT YOUR TELLY AND HEY PRESTO ,YOU CANT SEE ANYTHING BEHIND IT

put mdf up first

hmmm…might be too heavy. would be a pretty expensive way of finding out too lol

Ummm…HELL NO!! There is no way I would hang my 42″ Aquos like you mentioned, unless you like throwing away over a grand on your new TV.
I would look for other mounting options, like the dual steel pole stand, which has a low profile, looks slick, and allows for verticle adjustment of mounted TVs.
Sanus and BDI are pretty sweet, just remember to keep your LCD within the vertical 30 degrees, or so, of your seated viewing plane.
Good luck, but don’t go cheap.

Not unless your doing it as a favor for an old girlfriend or boyfriend maybe to get back at someone!!

um…not really…the mounting should be attached to studs…how secure is your ceiling…you may want to hang it instead…the best thing to do would be check into professional installation.Would be a shame if the tv fell…plus if someone else does it,they are responsible for loss should it occur.

Hello all. I am facing the same saga and am intersted if anyone has done this. I too have a double layer honeycomb plater boaed. No stude at the back at all. The Plasma TV I have bought weiths 38 KG. I have also got a mounting bracket that can bear up to 70 Kg. I don’t want to drill masoney bolts into the concert wall behind the honeycomb wall as it may compromise the dryness of the drywall in long term. Have got 10 of those butterfly steel anchors but am not sure if the plaster wall will hold up ?

Well, I managed to put the TV up a week ago and seems pretty sceure. Here is how I did it in case anyone else is facing the same dilema.
1) I cut a rectangular piece of 12mm MDF. About 700 x 500mm. Big enought to spead the load and small engough to be hidden on the wall behind the TV.
2) I drilled 8 pilot holes in the MDF. These were to install the MDF to the wall.
3) I also positioned the TV wall mounting bracket on the MDF and drilled a further 6 holes coinciding with the holes in the mounting bracket.
4) I positined the MDF on the wall using spirit level to ensure it is level, then marked up the 8 holes on the plaster.
5) Drilled 8 holes of 60mm diameter right through both of the plaster layers and honeycomb cardboard inbetween them.
6) Bought 8 masonery ancher bolts from Jewson. These were the type that the M10 bolt in the inside is a straight bolt, hence the small feature at the end which pulls up and opens the ancher flanges is a seperate component and integral to the M10 bolt.
9) The gap between the plaster wall and masonery wall is about 50mm and the plaster wall is about 65mm, hence I needed the M10 bolt of the anchor bolts to be protuding out of the anchor bolt by at least 135mm so to allow for 12mm thickness of the MDF also about 8mm for an M10 nut.
10) I looked everywhere (B&Q, Screwfix, Homebase, White&Milne, Wicks) and none had any anchor bolt with that much of free length for the M10 bolt. Hence I bought the M10 anchor bolts desribed in (8).
11) Bought two M10 rodes of 1 meter length. Cut to the required size such that the free length outwith the anchor bolt will be 135. Replaced the bolts inside the anchor bolt with these.
12) Screwed all anchor bolts into the hole drilled in the masoney wall earlir.
To get to the nut of the anchor bolt (which were now positioned behind the plaster wall) I used the type of spanner which you nomally get to screw the spar plugs on the engine. Basicall a longth pipe with one end formed to act as the spanner. This way I did not have to cut a big piece out of the plaster wall.
13) Screwed the TV mounting bracket to the 6 holes drillered earlier in the MDF.
14) Screwed 8 nuts (M10) to all M10 bolts which wer now sticking out of the plaster wall by about 20mm. I screwed the nuts such that they were sitting level with the surface of the plaster wall.
15) Introduced the MDF and mounting bracket assembly to the 8 bolts so that back face of the MDF sheet was resting on both the plaster wall and the nuts screwed in (14).
16) Using 8 washers and M10 nuts, secured the MDF to the wall.
17) By TV wight 38 KG. The bracket is one of those type that allows TV angular position to be adjusted or indeed pulled away from the wall by about 600mm. The bracket itself weight about 10 KG.
18) Before introducing the TV, I hung from the bracket to ensure security and the hole thing is solid as rock.
19) added the TV and now happy viewing plus that I can change the angle of TV such that it sits on the corner of the room (45 degree to each wall) which is the preferred position of the TV that I wanted.
