VHB double sided tape is the stuff to use Angela.
Various suppliers and brands available,we use 3M 4952 VHB

At a guess I would say poor surface prep to it failing.

Hi Angela
I have had similar problems before
You need to make sure that all surfaces totally de greased and keyed with scotch brite pad or similar so that the glue has something to bite into.
You also need to make sure that the two parts of the glue are actually mixing correctly especially when you first start using the glue
Hope this helps

hi, i am not sure what we are using now, but penlock also let us down on the same problem.

Interesting, I was just thinking of stocking some for sign trays etc.
I saw the info sheets stressed that the surface had to be roughed up though.I’ve also seen glued aluminum signs come apart because corrosion has lifted the surface coating.
