Secure loose Plasterboards

[chriselevate]

In a house I've bought I have noticed that a room has been overboarded on the walls. Some of the boards are loose and when pressed you can feel the deflection. No crack have appeared yet but I'd like to secure them before they do or it causes any problems.

I'm guessing there are tips/tricks to secure the boards rather than having to rip them off and redo the job. Other than the fact they are loose in places the room is nicely finished so I don't really want to make a big mess but I'm happy to fill an holes and make good anything when/where necessary after carrying out the fixes.

Thanks for your time and help.

depends on construction
is this a new build ??
dot and dab??
plasterboard sandwich??
not enough studs/noggins ??

Yeah I've got you.

• Is this a new build - the house is early 70's
• Dot and dab - I'm not sure how they've secured it but I'm guessing not traditional dot and dab as the deflection is only a few mm's and it sounds like it's a Wall/pb underneath that they've gone onto.
• Plasterboard sandwich - it could well be this or it it's the original rendered/plastered wall behind.
• Not enough studs/noggins - definitely not this as it's not a stud wall.

The room backing onto it I can feel it's a solid internal wall as apposed to a partitioned wall.

Assuming it's a solid wall that's been dot and dabbed - but not held properly, then you could drill a few holes into the loose areas, and pump a bit of adhesive foam in the holes

Cool, thanks. The only problem is that I've had a feeling that the gap between the back of the board and whatever it's sitting on is literally mm's so I don't think there would be enough of a gap to pump some foam in. Any other suggestions or tricks/tips I could use?

The only other option I can suggest, is easydrive countersunk brick screws to ties the plasterboard into the wall.

Is that just a screw that allows you to screw directly into the substrate? Instead of drilling, plugging and having to sink a washer into the face of the plasterboard and making a mess?

Yes. Take a look at these. http://www.screwfix.com/p/easydrive...fOd6ftBUmBFYQIQxNdGoE_jtC-rGITMD_1RoCJCTw_wcB

Depending on how deep the plasterboard and adhesive behind it is, you may want to go for 60 or 75mm instead. You just drill in with an sds drill about the width of the screw shank (or half a point less) and then screw in using a tork bit.
