Wall mounting a TV

[RizzoTheRat]

Not too sure what my wall is made of, is it fair to assume that a downstairs internal wall which definatly isn't studwork is probably concrete blocks and therefore best bet is to use those expanding bolt jobbies?

[Ricky_M]

If it is concrete block, you should be ok with 10mm plugs and coach bolts. Just to give you an idea, most of the boilers I fit come with 4x10mm plugs and coach bolts to secure them to the wall. They're around 50 kilos.

Anchor bolts are bit over kill IMO.

It probably is overkill, but boilers also tend not to move and the load is usually balanced equally.

Also most parents wouldn't let kids near a boiler.

If its block and set or brick then shield anchors every time.

If its stud then coach screws

If its dot and dab then rigifix anchors

If its thermalite then you're on your own.

If its Thermalite/lightweight blocks (very unlikely) use a drill bit 1mm smaller than recomended for the plug, eg: brown plug=7mm so use a 6mm bit. Use on drill, not hammer. Most likely to be concrete block.

Drill a test hole and see what comes out. I put a 43" Plasma onto a brick wall the other day for a amte, just used the hex head chunky screws and plugs that came with it, but as said, make sure the plugs are a tight fit. Gripfill the plugs in if loose.

Built in the late 1960's if that makes much difference to construction methods.

Defiantly not stud (doesn't sound hollow when tapped), what's dot and dab?

[callyman]

Dot and Dab is dabbing largeish blobs of adhesive directly onto a wall brick/block and sticking the dry wall to it, levelling up the board to one another with a long straight edge, saves having to batton and screw to an uneven wall etc. just stick on, tape edges and plaster. disadvantage of this method is when you want to fix something like a tv to the wall, meaning you will have to cut a rectangle out and baton the wall (gripfill/screws) to bring the bracket flush with the dry wall. I have done this once before and is a pain but works ok.

Dot and dab can sound hollow too. I have dot and dab walls with thermalite bricks behind and used these http://www.wickes.co.uk/PVCu-Window-Fixers/invt/51... to put up my bracket. When you screw the fixings, 'wings' come out of the plastic cover and embedd themselves into the thermalite.

As Plotloss says, if it is dot n dab use Rigifix... http://www.deltaleigh.co.uk/products10.htm

No need for cutting a section of the plasterboard - they are very secure.

If its a flat-to-wall mount there is not much load unless its a big plasma , if its an arm bracket be more careful . I use frame fixings with a hex head and use an impact gun to tighten . Not had one fall off yet and have fitted over a hundred so far .
