Fixings for dot and dab plasterboard

[ChrisinShropshire]

I want to hang some mirrors on dot and dab plasterboard walls. This means that the screws will not be screwed all the way into the plasterboard fixing as the bracket on the mirror needs to hang on it.
I am also worried that there may not be enough room between the plasterboard and the breeze block for the fixing to fit.
I did think of drilling through into the breeze block and inserting an 'old fashioned' rawlplug. The screw would expand the plug in the breeze block and in the plasterboard.

Would this work or are there better solutions, please.

A plastic plug expanding in plasterboard will blow it, best to try Corefix which is part plug and part steel ferrule. You can measure the gap between board and block by drilling a small hole and pushing a piece of wire through watching out for pipes and cables.

For a small mirror a self drilling fixing will be fine. Eg https://www.screwfix.com/p/easyfix-self-drill-plasterboard-fixings-metal-32mm-100-pack/2422H

For a bigger mirror hollow wall anchors are good. You do need to get the right length and have enough cavity to push the unexpanded fixing in. Eg https://www.screwfix.com/p/easyfix-hollow-wall-anchors-8-16mm-m5-x-52mm-10-pack/12229

It’s dot and dab , no cavity.

Corefix is what i suggest

I think he means the space left between the dabs?

As I said done correctly there should be no gaps and any there are totally inadequate to accommodate the fixings suggested .

Dot and dab done properly absolutely does have a cavity behind it albeit only about 5-10mm.

Agreed

Anyway, OP, use Corefix..
