TV wall bracket

randomstuff

Hi, trying to attach a swiveling TV bracket onto my wall.

I bought some of those metal anchor wall plugs to use, because there is plasterboard.

Issue is, I didn't realise it's the edge of the house and once I went through the plasterboard, there's a little gap, maybe 1 or 2cm, and then concrete.

What should I use to attach the bracket/TV to the wall? Its a 40" TV if that matters.

Will plastic plugs work with a gap like that?

Just to be clear: there's 2 cm of plasterboard, then 2cm of a gap, and then concrete.

No chance of them holding on a swivel bracket with a 40" TV. you'll need to find studs (vertical wooden beams between plasterboard and concrete) or better again, masonry drill through the concrete and then use proper concrete fittings.

If any of the above confuses you, don't risk it and get help. I've mounted many flat screens on plasterboard but they low weight LED, are on good wide brackets with the load well spread and non swivel. For anything adjustable, I'd definitely be aiming for stud or blockwork.

I see you're in Dublin so give ive us a shout if you've no luck and I might be able to help you out.

Op, my guess is that you have pb with a dab fixing, if your 20mm/20mm is correct and there wont be any studs.
If it is correct, then thats 40 mm so I would use 120mm long. 10mm diameter compress nails and then raw plugs in the compress nail holes

That's a great idea very clever

Thank you!, not mine originally, picked it up here: have used it many times, once the drilling is accurate it works really well

I'm not sure what compress nails are.
Do you mean express nails?

Yes, he does. It's s great idea but overkill as the hole has to be drilled anyway for the express nail so better off just getting the masonry plugs and screws. 75-100mm will work fine. Good spot on the blobbed boards. 1-2cms would obviously indicate the absence of studs.

Thanks for all the suggestions.

I got some 10*80mm bolts with matching plastic plugs to put into the wall.

Once the bolts are in the wall, the bolts will be about 50mm in concrete, 10mm empty and 20mm in plasterboard... This will be fine, right?

Manufacturer of the wall bracket recommends 4 bolts, I'll be putting 6.

The TV is a modern 40 inch flat screen, 7.8kg according to manufacturer.

I'm guessing you meant 10mm plasterboard and 20mm space

You'll be fine with that though (50mm in concrete), no issue.
