Mounting TV - New build plasterboard

Rony

Hi there,

I am soon to be buying a 55" TV to wall mount in my lounge. However I have heard that plasterboard walls in newbuilds may not be the strongest and may not hold the weight.

However I have been reading the welcome pack that I got when I moved in and please see the highlighted in the picture below.

Does this mean I do not have to worry about any extra supports? I can literally just drill into this board? That's pretty convenient. It says it is 1500mm to centre from floor, but it doesn't mention how far left or right it is. I presume logically it would also be the centre of the wall.

Thank you,

It doesn't mention the horizontal position but I would guess it's central unless there are any other built in features which would influence that. But I would want to be certain before doing anything.

I imagine if you tap the wall in a few places it will sound quite different where the ply is. You may need to drill a few exploratory holes: ply should be pretty obvious compared to the void behind plaster board.

Make sure to use a wire detector and don't drill in a horizontal or vertical straight line from any switches or sockets.

Depending on the weight of the TV you can get away with mounting it on hollow plasterboard walls using spring toggle fixings.

It may be possible to remove a socket or switch to probe along the cavity to a stud, then measure along to see where the other studs are, usually 60cms appart.

Invest in a stud detector they’re not too expensive, the one I have finds cable, pipes and studs

Stud detector may detect metal studwork, but would it detect timber?

If your trying to find where it starts and finishes from left to right on the wall, walk along the wall tapping it with your knuckles. The sound will change where the ply is.

I've used a detector on a home I moved into. Very useful if annoying at times.

I also kept the magnolia walls while I was doing work so that I could lightly mark in pencil what I'd detected and levels for what I was putting up, then all work didn't have to be done at that moment. Easy to paint over when finished. Fine decorating can be done later.

Huh?

Of course it would a stud detector is actually a metal detector in a different name 

It of course won't detect wood but it will detect the screws in the wood that are used to secure the plasterboard to the timber

Op - you know the height to the centre of the batten , simply tap left and right of this centre to find out how far along it goes
