Wall advice

[jimmyca69]

Plan to wall mount my TV (32" or 37") once purchased in the summer. Excuse the lack of technical "wall" terms as im not that knowledgable

TV will be going on side wall of house, from what i can gather it appears to be plasterboard of about 10mm thickness, which is connected to the brick wall. Instead of wood/metal frames found in floating walls, it appears to be connected via various random feet? i.e. when tapping wall there is solid bits of around 10x10cm where the plasterboard is connected to the brick wall i assume? Does that make sense?

Anyway plan was to mount the bracket directly onto wall with sufficient length screws to fit into the brick wall. Problem is though when im tightening the bracket to the wall will it "crush" the plasterboard thats sitting in between?

If so is it worth cutting out the bracket size to it sits directly onto the brick? or cutting out the plasterboard and then fitting a block of wood that fits flush to the rest of the plasterboard and then the bracket connecting to that??

Sorry if these are stupid questions im just trying to get on top of my planned work so im not doing it as i go along.

Any other suggestions welcome.

Thanks
James

The plasterboard on your wall is "glued" in place using a plaster based adhesive - technical term is dabbed i.e. dabs of adhesive on the back of the board fix it to the wall. You have already identified the main issue when fixing through plasterboard to the solid wall behind - it can be all too easy to crush the plasterboard if you overtighten the bracket unless you use spacers. You could do as you suggest, cut out a section of plasterboard, fit suitable timber to the wall and then fit the bracket on top. This has some merit as it also gives you a largish opening that you could use to help run cables behind the plasterboard and therefore avoids having cables running on the surface of the wall. The other option is to buy/make small spacers that are used at each fixing point and simply bridge the cavity in the wall.

Thanks Neil, thats what i thought. Didnt even know they used the dabbed method until researching this today! Cheaper than using a frame i guess.

I did just find a thread on here that mentioned the spacers idea which would probably be best for me.

I think i will run the cables down in the cavity but probably wait until the bracket is secure and then drill a hole (located behind where the tv would be) to pass the cables down the cavity.

The TV position will be above a simple fireplace surround and electric fire so can mess around with the wall behind that to get the cables out without worrying too much as any damage will be covered by the fireplace.
