Just been refitting some skirting boards after a re-plastering job
I decided to glue them back, and went through the Toolstation site to find a suitable adhesive. I was aware that the walls weren't perfectly true, so they'd need holding in place to avold gapd along the top edge. I went for Pinkgrip Solvent Based, on account of its description: "Its amazing grabbing strength not only removes the need to pin under the workpiece to prevent slumping, but its revolutionary initial 'direct bond' eliminates the need for double stick methods." which seemed to fit the bill.
So, I squirted the stuff liberally over the back of the skirting (about 3m long) and applied it to the wall. Came straight off; no way would it take even the *slightest* pressure to make it conform to the profile of the wall. Shit - time for screws then. I drilled the board and plugged the wall for 2" screws at the two most strategic points - but by this time the gloop on the board had skinned over and was useless. I scraped it all off, reapplied it, and screwed the board to the wall.
Looks absolutely fine now, its completely firm, no gaps etc. But I'm asking myself, really, what was the point of all that pratting about with Pinkgrip? Not convinced it's made any real difference to the end result; and certainly achieved nothing another couple of screws wouldn't have done (having already broken out the drill etc)
