I need to repair a particle board desk where an "insert nut" pulled out of a recessed hole. An "insert nut" is one of those toothed monsters that screws into the wood, then you screw a bolt into it.
I plan to put the insert nut back in the hole and use epoxy to fill the void where the particle board crumbled. The epoxy will also hold down some splintered laminate. I'd like to put in the epoxy, then use a clamp to apply pressure with boards on each side of the hole.
Of course, I need something to put between the epoxy and the boards that is immune to the epoxy. Is there such a substance? I usually use plastic wrap or aluminum foil when I do this with carpenters glue. Am I SOL here? Thanks.
