I need to put some skirting board up which will be fixed to some skimmed, dot-and-dabbed plasterboard.
I need to fix it without nails / screws however, as it's in a basement/cellar conversion, and there is waterproof membrane behind the plasterboard which I can not puncture.
I'm planning on using No More Nails / Gripfill, but have struggled getting it flush in the past without putting some pins in until it goes off.
One useful thing is it is in a narrow hallway (about 1.2m) so I'm wondering if I can get away with "wedging" the skirting with 1.2m pieces of stud across the hallway until the glue goes off.
Is there a more elegant solution than this? (Am also worried in case the no more nails gives way at a later date!)
