TV Wall Mount

jmike72

Hi,

I'm in the process of refurbishing my home office, and want to mount my 34" wide monitor to the wall and free um some space on the desk. The monitor weights 8kg and have a wall mount I was to use somewhere else that can hold up to 20kg, so in those regards I'm covered.

My problem is the wall I intend to mount doesn't have any studs... and before someone suggests it, this is the only part of the wall I can use, and have a 48cm surface from the window corner to the wall on the right (see picture).

The mount has a 6cm x 17cm mount base that should be fixed on brick wall or onto a stud, but was thinking I could get a metal plate, around the width of the wall (48cm) and have the mount welded into it. Then I would fix that metal plate into the drywall with 6 or 8 bolts (my Picasso skills aren't great, but you see the idea on the picture below). Mount will be mostly at 180 degrees (see second picture).

Will that work and the drywall will hold it? What would be the risks? And last, where could I get this metal plate made and welded to the TV mount (Dublin area)?

You don't need any additional metal plate fabricated, you just need to fix the bracket through the void into the blockwork/brickwork behind, using corefix or whatever.

Would a desk mount not solve the problem without having to drill the wall? Something like this?!

That's exactly what I did - I have 2 monitors mounted on a single arm attached to the desk. The width of the 2 monitors is about 40 inches in total. Biggest benefit of this solution is the ability to move the desk, you are not tide to one corner or part of the room. Got the arm on Amazon, but choose carefully to ensure you get a good quality one. Mine was about €30, money well spent.

This is the one I bought :https://www.amazon.co.uk/gp/product/B01MR397OH/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

Perhaps search for that brand,I was surprised by the quality of the item

I don't know at what distance is the block/brickwork, can be 1cm and will be easy, but can be 10cm and unreachable.

Have one, but due to space problems, need to build a foldable desk and can't use the desk mount on it.

Only option is the wall mount.

You can get express nails up to 150mm.

There's a fixing for every application.

Need to check the distance from the drywall to the brickwork.

But if the distance is too big, would my idea of a metal plate work?

irishbuzz

You already mentioned the wall does not have any studs so whatever way you mount it you will need to go back through and into the blockwork. Depending on the distance from your surface to the block I would probably use Corefix as Lumen suggested and just mount it directly.

If you are determined to use a backing plate then why not just use a square of plywood. Easier to work with and handy to paint afterwards and hide it.

As irishbuzz says, plywood is easier.

I don't really like fixing to plasterboard. If you don't do it properly you can just end up ripping huge holes out of the wall (this happened to me with some bookshelves in my last house). TVs aren't very heavy but the leverage on the top hole is substantial when the mount is extended.

I'd measure the cavity and see what you're dealing with.

jmike72

Just spoke with the builder and he told I would need 60mm screws to reach brickwork, and I should be good with 80mm masonry screws.

Can't post links, but might get this ones from B&Q to be on the safe side.

Lumen

I've only used that type on anchor directly into blockwork, not sure it's going to work through a cavity.

Is there a reason you wouldn't just use concrete screws?

What type of bricks/blocks do you have? Traditional high density blocks will take a concrete screw but new builds tend to use low density thermal blocks which are better suited to an expanding anchor.

jmike72

Don't know what type of bricks/blocks I have...this was build in 2008.

I thought about those ones as they are heavy duty, but if concrete screws work, I don't have a problem using them. I'm not into construction, but I assume concrete screws would be like this ones?

No, that's a frame fixing. Concrete screws are screws that go into concrete. :-)

Thanks, the builder told me to use masonry screws, so I had sent him the picture above and he told were these. Now I'm getting more confused what to use...

I just looked at Corefix to see if it was suitable for you, but they specify a max of 45mm from the face of the wall to the brickwork.

I'd measure the distance - stick a drill in through the plaster and measure it back to the block. If it really is 60mm or greater then go with this type of concrete screw:

You can get them in most/all hardware stores.

dodzy

Take a small tipped screwdriver and twist/punch a hole where you ideally want the bracket to go.

Push screwdriver all the way to blockwork, mark, extract & measure distance from plasterboard wall to block.

Get 2 concrete screws (Lumen linked above) 50mm longer than this depth along with a suitable masonry bit.

Drill 2 holes to required depth, fit screws to bracket, don't over-tighten.

Job done.

Lumen

I respectfully offer the following improvement to dodzy's suggestion:

Drill 2 holes to required depth, use a drinking straw to blow the dust out of the holes, fit screws to bracket, don't over-tighten.

Often thought about trying these GripIT yokes I saw on Amazon. https://www.amazon.co.uk/Grip-TV-Bracket-Plasterboard-Fixing/dp/B013YPWIWA/ref=sr_1_5?dchild=1&keywords=gripit&qid=1630345648&sr=8-5

"one fixing holds up to 113kg". I'd love to see that plasterboard! It must be as tough as Putin.

jmike72

Ended up buying and using the ones the builder mentioned and testing them during the evening with some weights on the TV mount.

Tomorrow should mount the monitor, but all seems good as it has a 60mm (if not more) grip on the wall.

Thank you all.
