Complete noob question: Walls to mount tv on?

[Richyboy]

How do you determine whether a wall is suitable to mount a tv on? Inner walls of my house are like this hollow plaster board (not sure of the terminology, its a new build house).

[Slagathore]

Ideally, you'd need to find a stud, but from what I've seen on the length of brackets, they won't necessarily span 2 studs, so you might get 1 side of fixings in, then the other side would be in to the plasterboard?

What size and weight TV is it? I'll put one up eventually, but I put ply behind the plasterboard, so I can screw straight in to that instead. The middle fixing in to the stud, then the 2 side fixings in to the ply. Using this type of mount:

You might get away with plasterboard fixings if it isn't a very heavy TV.

You could cut out the plasterboard between the studs and fit some ply, then tidy it up.

My brother wants the same doing in his bedroom, but the problem is finding a stud, and even if we could, it wouldn't really work with the type of wall mounts we're looking at, if the studs are where they would normally be.

Choose a wide mount such as this one (random Google but they are all very similar)

Locate your studs (400 or 600mm apart generally), pilot drill a hole and stick a decent fixing straight into the centre of the stud. I did this recently for a 40kg TV and even though the mount isn't Central on the studs it is going anywhere, although I did squeeze the plasterboard and stuck a superficial crack up the wall.

Unless it is a really big and really heavy tv it will be fine on plasterboard fixings. Ideally hit a stud, but if not it is no biggy.

How heavy is a kitchen wall unit full of stuff compared to your TV? What about a radiator full of water?

Dot dab hollow plasterboard or a studwall with probably metallic studs these days? The former will make life easy.

No more nails. Job done.

Drill straight through to the other side, through bolt it using washers on the other side of the wall and hang a picture over the bolt heads.
You'll never be worried about it falling off the wall. Can you honestly say the same using rawlplugs ?

[ecotec]

find a stud and use good wood screws with big washers

if its a thermalite wall use these:

Drill a hole, glue the plugs in with no more nails and let it try, then fix the bracket to the wall. If you don't do this, they will most likely pull out when you put the screws in. stty blocks used in most houses these days fall to pieces when you drill them.

Whatever you do make sure you do it properly and channel the cables in. If you don't properly hide the cables it will look st oh and get a proper spirit level I hung one once and it was out by something like 2mm annoyed me to death.

[anonymous-user]

I chased my cables into the wall using an angle grinder to cut the plaster board. You should have seen the dust, my wife went berserk!

With decorative trunking you can get this effect (this is not my house):

Impact drill and some of these, into blockwork, timber etc -http://www.toolstation.com/shop/Screws+%26+Fixings/d90/Frame+Fixings/sd1950/Fischer+FFS+Frame+Fixing+Screw/p85179

No offence, angle grinder on plasterboard. Lmfao. Straight edge and Stanley knife would have sufficed.

British Gypsum give some maximum fixing loads directly into their plasterboard - have a search of the White Book online. Having said that, they also recognise the issue this causes people and are looking at new plasterboards that get rid of the problem:
