Hanging an LCD screen on hollow plasterboard Solved

Question

Hello everyone
I just acquired a 32-inch Sony LCD screen that weighs about 15KG

I want to mount it on the wall of my room, but the problem is that my walls are made of hollow plasterboard
For those who don't know what it is, it's 2 sheets of plaster that are 5-10 mm thick, and between these two sheets, there is cardboard in an alveolar shape (like honeycombs)

I would like to know if it is possible to hang my screen on the wall without damaging it or even preventing the screen from falling
And I'd also like to know which screws I need to buy (Molly plugs???)

Thank you for your help

Hello

You can use molly bolts. The simplest way is to fix a strip the size of your TV minus 1 cm so that it isn't too visible; this way, the weight distribution will be done by it and the 3 or 4 placed bolts. The bolts can support a considerable weight; the drawback is what the wall can support with this method, which eliminates that issue. It’s total weight / number of bolts.

Example for a 95 cm long TV

Strip of 93 cm fixed by 3 bolts spaced 30 cm apart (load per bolt ratio 5 kg)

Then you just need to fix the TV.

Hello,

I mounted my 40-inch LCD to the wall a month ago (also in hollow plasterboard) and there are no issues; it holds well! The weight of my TV is 13.6 kg.
I used a fixed wall mount (neither adjustable nor tiltable) that I bought for 25 euros at Ikea. 3 Molly plugs were enough to secure everything... Happy with the product!
However, the only downside with the hollow plasterboard is that even when drilling with a hole saw to pass the cables through the wall, it’s nearly impossible with the hollows, unless someone has an idea... (I do not want to install a cable management duct between my TV and my TV stand).

Hello
Regarding plasterboard, which is generally 13 millimeters thick,
For all weights under 10 kilos per anchoring point, you can use a wedge anchor (the real one). For any other situation, a Molly bolt (make sure of the quality) is the ideal product.
What you need to know is that the breaking point of plasterboard in terms of pull-out is 57 kilos per fixing point; you can use any type of anchor at that stage, it will always be the plasterboard that gives way.
If you have any other issues with fixing, I'm your guy!
Happy installation!

I also had this problem when buying a new apartment, surprise!
You can hear everything, in the bathroom, bedroom, toilet, and kitchen!
Not to mention the fact that hanging heavy and high kitchen items required a real handyman who came to reinforce the wall with thick wooden strips....
Cardboard walls, you have to be bold!
