How to hang a plasma on a dot and dab wall?
Discussion
As per the title really, got a fantastic (or at least i hope so as I haven't had a chance to turn it on yet!) Panasonic 46inch TV from DD (courtesy of Deristrictor) and need to mount it on my brick wall that has dot and dab plaster.
Can you get special bolts that will support the massive 35kg weight or will the plaster give way regardless of fixing?
Would a good alternative be to cut away the plaster to expose the brick, then cut a piece of wood out (same thickness as between the brick and plaster face)and fix direct to the brick so no air gap to worry about, then fix the plasma to the wood and brick, in which case, which fixing should I use?
Any help appreciated, preferably from experience so I'm not someone's learning curve!!

You need to get fixings that attach to whatever is behind the plaster board. I used these http://www.wickes.co.uk/Fixings-Frame/PVCu-Window-... can't remember which size though. They were long enough to go a decent way into thermalite bricks behind the plaster board. If I had 'proper' brick behind the plaster board I would have used anchor bolts, http://www.screwfix.com/prods/33836/Fixings/Shield... Again make sure they're long enough to anchor in the brick and not the plaster board. My 40'' Sony weighs 21.5kg, so I suppose you need to get a fixing that can take the weight of your tv. I dangled myself off the wall mount before I put the tv on it just to make sure !! I did a fair bit of research before deciding what to use, even considering resin injection anchor bolts.

How much of a gap is there between the plasterboard and brick? What type of bracket are you using? Does it have a large surface wall plate?
Use some 3" or 4" size 12 screws and brown plugs. 6 screws will be enough. If there is a gap between the plaster board and brick then use a spacer, I usually cut a piece of plastic conduit and screw through the centre of the spacer clamping it between the bracket and the brick.
If there is no air gap between the PB and brick then forget the spacer, the PB will be strong enough.

35kg really isn't that heavy. A few screws in brown plugs would take that weight easily.
However, I would do it properly and use these http://www.deltaleigh.co.uk/products10.htm they are specifically designed for what you are trying to do. I have used them loads of times to hang tvs up to 100kg on dot and dab walls and never had a problem.
Only word of caution would be is it proper brick, or thermalite block behind the plaster?

Those rigifix bolts are very good indeed.
Frame fixings or even shield anchors will also work.
If its thermalite there is another type of fixing but it would be relatively unusual for this to be the case, especially on the ground floor.

I have the unfortunate pleasure of living in a house on a newish estate (5yrs), every house is built of thermalite and brick cavity. Edited by SwanJack on Thursday 26th March 09:02
