Plasterboard to Plasterboard help req

[pablopete80]

I am about to attach some insulated plasterboard to an existing (flat and straight) plasterboarded wall. I know its not technically woodworking but will be housing my tools once done. As i have always got good advice i thought i would ask you all for some this time too.

The existing wall is covered in lining paper on p/board - Does this need to be removed?

Whats the best way of attaching the new insulated plasterboard. (the exisitng is dot and dabbed not battened). I will be adding a mechanical fixing for fire safety but want to stick it up for speed. So is it dot dab (if so as the wall is flat is there a more economic way of doing it ie less adhesive) or some other sticky way?

Cheers in advance for your help.

How about PU foam adhesive/ gapfiller, easy and quick.

Is that what gripfill is?

Use expanding foam adhesive at work all the time. Screwfix stock it.

Get the loose paper off and buy some board adhesive and dot and dab it. I might not know much about woodwork but years of plastering experience
