I want to fix a metal wire cable tray to an Ikea Linnmon desktop with screws, however the desktop has honeycomb filling therefore it is not suitable for screws. I think maybe attaching a timber block to the desktop then fixing the tray to the block will be a solution. What is the best way to do that? I am thinking of glue, but which type of glue? The material of the desktop is Fibreboard, Acrylic paint, according to Ikea website. The timber block I plan to use would be untreated (I guess?)
Thanks in advance!
