End of year task is getting a lightweight and portable backdrop onto the baseboard; the backdrop (Corflute) also supports some Knauf board attached perpendicularly (that is, the backdrop is vertical and the Knauf is horizontal and used to support some lightweight scenery).
Some time back, I tried using PVA and two-part epoxy but found that it didn't make a permanent bond. I then tried Gorilla glue which did the job but, some months later, I have found that a slight twisting or bending action causes the bonded parts to cleanly separate - it appears that the Corflute is quite impervious to glue! I also found the same problem with balsa wood glued to Corflute.
I am tempted to fix the Knauf board into position with pins and glue it with Gorilla glue, then horizontally drill a 5mm hole so I can glue a dowel in place as well. Seems overkill, but it looks like mechanical bonding is needed in addition to glue.
Has anyone successfully glued Corflute to anything?
