What type of Glue to use on Polystyrene (or Styrofoam)?

If you are using polystyrene and you need to glue it together then there are a number of glues out there that purport to do the job. It can be confusing though trying to figure out which glues are going to work the best.

Terra over at HalloweenForum.com was getting so frustrated with all the mixed information out there that she decided to do a test of her own of the following types of glues:

  • Loctite PL300 Foamboard Glue
  • Super 77 Spray Adhesive
  • Glidden Gripper
  • Foam Fusion
  • Gorilla Glue
  • Great Stuff
  • StyroGoo

She used both scratched and unscratched surfaces in the tests and compared the results after 24 hours and then after 48 hours.

Firstly I recommend that you watch the video and also subscribe to her channel as there is lots of great content available. She goes into great detail and explains how easy each was to apply and which ones to avoid using in certain conditions.

If you don’t have time we also list the top three types of glue as a result of her experiment further down the page.
