Finally know what wall i'm mounting on,

It's plasterboard, then a gap, then a brick wall. The gap is maybe 2 inches.

So, i have rawl plugs that i got with the bracket but i'm unsure how to install them extacly, will i need a very big masonry drill bit that's the same size as the plug? I'm not sure on the exact size but i got them with the bracket.

Will i need any resin or should it be ok in brick? One last thing is should i buy new plugs for brickwork as the ones i've got have the wings on them which i don't see working on very hard materials like brick.

Thanks guys.

Here's a could of 'progress' pics.

Re: Finally know what wall i'm mounting on,

I had to mount some wall cupboards onto a stud wall and here's what I did. It may be overkill, but I prefer it that way

The wall will be created by vertical battens positioned every 16in or so. You can get a device called a stud finder or drill some holes and use a piece of wire to feel behind the plasterboard until you locate the studs. If you always win on the lottery, offer up the bracket and screw straight into those studs with standard wood screws and the jobs a guddun'.

If you are not so lucky, you can cut the plasterboard vertically down the centre of two studs and across horizontally, so you remove a rectangle of plasterboard. Try to keep it for a template if it comes off in more or less one piece. Then cut a piece of timber to fit in between the vertical studs horizontally where you need your bracket. You can screw either end into the existing battens and/or drill a larger hole half way and then a smaller hole into the actual horizontal batten, then use a masonry anchor to screw it into the breeze block (that assumes the timber is the same thickness as the existing battening. When you are done MARK IT, so you don't lose where it is and either replace the plasterboard with a new piece, with plasterboard nails and skim over to make good.

That is how I would do it, but it involves a bit of work.

Re: Finally know what wall i'm mounting on,

Hi Graham,

Thanks for the reponse, firstly, they're are no studs on this wall, just a gap & brick & then a few inches across will just be platerboard & brick (no gap) it's like this all over the wall. I brought a stud finder today hoping to find some studs but no luck. As you can see, at the bottom of my wall there's a vent where i stuck my hand in & couldn't feel any studs just solid brick.

Re: Finally know what wall i'm mounting on,

Its very strange theres no studs behind that plasterboard, there certainly should be. If that really is the case mate i wouldn't be hanging a TV on that wall.
Heres what i would CONSIDER looking into doing..... Depending on what is actually behind the plasterboard i'd think about cutting a hole in the plasterboard and mounting the bracket on the solid brickwall so you can have the tv recessed

Re: Finally know what wall i'm mounting on,

use 'long threaded bolts' to screw into the brick behind, my wall was the same and that was the solution.

Re: Finally know what wall i'm mounting on,

I'd use expanding anchors, something like this -

screwfix
- I can't tell the length of the threaded part from their description, but you can see the type of fixing I mean from the picture. Basically, you want the type with a long threaded stud, sufficient to go across your 2" gap. Have a look in your local B&Q, where you should see the right thing.

The important thing to remember is that you need a sleeve over the threaded rod, so that you are not tightening your bracket up against the plasterboard, but against the brick. If you don't, the plasterboard will simply collapse back against the wall. Pack it out with big washers or a short length of steel tube, or something like that, to level with the plasterboard. Then when you tighten it up, the load is transferred back against the wll, if you see what I mean.

Cheers,
markP
