Fixing on stud walls...help!

buglawton

There are joists spaced at a standard interval behind the plasterboard. You can detect them by using a cable detector which will locate the nails so long as the plasterboard is not foil backed for insulation. These joists make good supports and I've put loo roll holders (which will always come loose) on them. Now I'm looking at fitting a large TV on a plasterboard wall, not so simple as the joists don't match with typical TV brackets. I'm wondering if flat metal frames can be bought, screwed to joists then a standard TV bracket could be attached to such a frame.

What you think the plasterboard is holding the house up? the plasterboard must be fixed to stud or dot and dab.

Wow, thank you everyone for your responses! Helped us loads.

If there's masonry behind the plaster board then I'd try to fix the cupboard to the masonry, so it's taking the weight rather than the plaster board.

You can do it with screws and wall plugs, but it can be tricky as you typically need quite long and heavy gauge screws to bridge the gap between the masonry and the plaster board surface and transfer the weight. And you need to get the wall plug securely into the masonry.

There are specific fixings which make it easier, they look well designed but are quite pricey:

You can also get quite long, heavy gauge hammer fixings which may do the job and they're a bit cheaper.

Personally I wouldn't hang anything too heavy like a cupboard or cabinet off a plaster board fixing.

as with a few people above,

for proper stud walls I use GripIt's the blue ones can hold a huge amount.

for plasterboard dot and dab on a breeze block wall I use Rigifix, again put in well and they are not going anywhere!

New LCD TV are light* even including the bracket.

Standard fixings are fine unless you are using a bracket with a large cantilever or plan to swing on the TV.


here are some load test for gripit that was mentioned above there are other and the info is available for them.

* 65" will be under 25kg and a bracket less than 10kg

The wall units in the kitchen will be held up by the kitchen fitter drilling through the plasterboard then into the blockwork and using wall plugs in the blockwork to support the units

Exactly, but if it's stud, then doing what Ganga said wouldn't be any use.

These are probably the best fittings i've used so far.. Better than the screw in ones, and easier to use!

I have used Rigifixes to hang a very heavy antique mirror on a dot and dab wall. You are right, they aren't cheap but they are easy to use and very effective. I would recommend them without hesitation.

I've used these for dot&dab:
