I used some excess DPM instead of proper tile felt under the tiles of the roof of my shed when I built it (well - its only a brick-built shed...)
The damn (no that should be *&>$£"!) squirrels which live around here have managed to get into the roof space and have gnawed several holes in this DPM, with the result that the shed is no longer "dust proof" from the crud which blows in under the tiles.
So, what would be the correct kind of glue to use to glue DPM patches over the holes?
I reckon its a polythene DPM - its a blue "plastic" - but I've never come across a polythene glue...
