Fixing Mirror to Dry-Lined Wall

[00mrmark00]

Hi all,

It's been a while...

Quick Q, looking to hang a mirror approx 8KG onto a dry lined dividing wall.

So 1/2 inch plaster board + space of 1 - 3 cms then the air block.

Have a few ideas;

1, x2 Redidriva either side of mirror to hang it on - not quite sure what the max load of these are.

2, Drill 2 holes wide enough to get the nozzle of a gripfill cartridge in and squirt in enough to create a bridge between the two material and let that go off before using a standard plug and screw setup.

3, something else...

Anyone got any other comments or suggestions...

Cheers all...

I personally prefer the hollow wall anchors.

For heavy objects it is worth considering cutting in to the wall and installing some secure timber battens, then repairing the wall and using the battens as a secure fixing point.

The description says you need one of these to set it...

Is this really necessary?

Of course I will need to wind the screws back a couple of turns for the mirror frame hooks to sit on.

Would this be ok?

You don't need a tool, just mark up for holes, drill a pilot so you get a good centre. Then the appropriate sized drill for the anchor.
Then insert anchor with screw, so the sleeve teeth grab your wall surface.
Then tighten the screw up, so the expandable sleeve grabs the internal of the wall.
Don't over tighten, then the screw can be loosened or removed.

Ok, thats sounds easy enough... Just hope there is enough clearance between the back of the p/board and the block for the anchor to open... We shall see...

Just one other thought, with these anchor fittings, will the fixing still be secure enough after backing off the screw a few turns to hang the frame on to???

Cheers all...

It will take more than just a few turns, for the expandable sleeve to grip, but you will know when it has, just be careful not to over tighten.
And make sure you get them in the right spot first time round as they can be a sod to remove.
I have hung kitchen wall units up using them, the wall units have been filled with plates and cups and still sound and secure and that was over 8 years ago.

They are too long at 43mm they will hit the wall and spin when tightened as the spikes on them will not be touching the plasterboard, just drill and insert plugs [frame fixings will provide long plugs suitable ] then you can just use extra long screws.
