Hi all

OK, i've laid out my trunking for wall mounting my TV and laid all my speaker cables behind the plaster board.

After the plasterer has been i'm ready to paint and get the TV mounted but i'm really unsure on how to do this.

I have the plasterboard then a 25mm gap. After that is a kind of breezeblock material which is 100mm deep. I say 'kind of' breezeblock because it's really very very easy to cut through it. I can cut through it with a knife in fact. Behind that is about a 50mm gap and then the bricks.

Anyway, anyone have any ideas how best to do this? It's a 46" TV and it's listed as being 25Kg in weight.

Hi Mr scared of Wakefield

this is Mr confident of Normanton

if the plasterer hasn`t been yet I`d cut out where the tv bracket is going to go and fix timber directly onto the blockwork.

Of you can use fischer fixings from B&Q (cathedral walk) make sure they go into the blockwork at least 75mm.

Or use rawl bolts at least 125mm long.

Use 6 at least and you`ll be fine

ps. if your really stuck pm me and we`ll see what we can do

Hehee, thanks Mr Confident

I was down at that B&Q today and the guy there wouldn't give any advice, said they weren't allowed for stuff like this (which I guess is understandable). So, I'll use one or the other of your suggestions, probably a bit too late for the timber option.

I have read about those Fischer fixings. If you had to go with one or the other which would you opt for? I can easily use 8, not a problem with the bracket. My only other concern was that this bracket can be tilted 15 degrees forward. You don't think that would loosen the fixing over time doing that do you?

But anyway, thanks for replying so quickly.

Dot and dab walls - Rigifix? I have used them and they are very good - I was also Mr Scared Witless

The prob with tilting brackets is.......they tilt.

this puts more strain on the fixings than normal so you need to be certain that you use the correct ones so my advice is to use fischer ones which so far when fitted correctly and using the correct size drillbit should be fine.

Thanks chaps. After doing further reading i'm gonna go with the Fischers. They look like they are the right thing for this job.

To be honest, I don't think i'll use the tilt all that much, it's just a feature I thought would be nice to have.

Will let you know how I get on.

Thanks again

Hi

I can strongly recommend the Rigifix mountings mentioned higher up. I used them to mount a 50" plasma on brick (though they say they are specifically designed to work on dot and dab walls too). Man are these things strong. I stuck 6 M8 in my bracket and could easily hang off it myself. The suggested max shear load in brick is 280Kg per fixing and 240Kg in aircrete.

The service from Mark grant was spot on too, nice quick delivery.

Couple of points to add -

1) Strictly speaking, the stength of these blocks is such that they aren't ideally suited to expnsion-type fixings. Resin anchors are the best bet, although that's not to say you can't have success with conventional fixings.

2) If the wall is dot and dab, be careful when tightening up the bracket. Thereis a gap between the plasterboard and the block, and it is very easy to comress the board back to the wall, braking it in the process. You can get round this by making bigger holes in the plasterboard, and packing the anchor out with washers so it is flush with the surface of the board. - Or as Al suggested, cutting the board out and fixing a piece of timber in its place.

HTH,

Thanks guys, posting this question and the help i've received has been invaluable.

I ordered those Rigifix from the place you mentioned last week and in the meantime also found some of the fischers.

Plasterer is coming today so i'll probably paint at the weekend and fix the bracket next week. In the meantime i'll work out which are best to use.

Thanks again!

[deniewibly]

oh, and yes, they are definitely dot and dab.
