Has anyone used an iron to set something glued with glue stick? Generally I find glue stick to bond poorly, but my extremely limited testing suggests that ironing it makes the bond very strong. I had to scrape it off with a blade/chisel and the glue bond was stronger than what I was gluing.
If anyone has tried this, is there some “gotcha” I should be aware of?
Detailed background
I need to glue a bunch of card stock squares onto an MDF base, in a pattern. I don’t want to use white glue or similar because I expect the card stock to warp, buckle, pucker, etc. I would prefer a solvent-based glue, but shy away from contact cement for this use because the working time is zero. I smeared some Elmer’s extra strength glue stick on the base, pressed on the card stock, ironed it with a very hot (dry) iron and wow - it surely seems like it’s stuck super well.
I plan to coat it with Mod Podge after completion, so that should deal with any minor lifting issues - I hope.
