How to Mount and Hang a Jigsaw Puzzle Without Glue, Optionally in Panels | Underwater 2000 Pieces

In this jigsaw puzzle mounting experiment, I built off of lessons learned in previous attempts.

Read about additional mounting projects here.

Note: The bond of this adhesive becomes permanent when pressure is applied, but it is positionable until then.

previously tried gluing in sections and using contact paper to create panels, but wasn't happy with those results.

I came across the 3M adhesive below in a search for larger foam boards, which I found hereherehere (not what the link sounds like!), and here.  During that search, I found self-adhesive foam board at the above links and here and here, which lead me to the 3M adhesive.  At some point I'll order some of the large foam boards for really large puzzles, but they have extra shipping charges due to the size.  I used this 3M 568 Positionable Mounting Adhesive in attempt 3 and was very happy with it.

In this attempt, I'm continuing a proof of concept to make the panels separable by adhering each half of the puzzle independently to foam boards while keeping both halves interlocked.

Ready to mount!


1) I drew the outlines where I needed to cut the foam boards.  My hubby did this part and he did a much better job than I have before!


2) I wrapped the edges of each foam board with black duct tape


3) In order to make the halves separable, I need to not put adhesive along the joining line between the halves.  I made pencil marks to remind myself where to stop on each half.


4) Readying the adhesive, protective sheet, and supplied squeegee used to press it down


5) Adhesive placed on the left side.  When doing this half, I measured the size needed, used wax paper between my fingers and the adhesive to keep it from sticking, and cut it to size with an x-acto knife.  The wax paper doesn't stick with a light touch, but the with firmer pressure needed to hold it in place while cutting it, the wax paper did stick and brought up some of the adhesive when I removed it.


6) On the right side, I decided instead to lay the adhesive down and then carefully cut it along the edge with an x-acto knife.  With just a light touch it's easy to move without issues to get it positioned just right.  I liked this method much better.


7) On the remaining area I overlapped it and trimmed off the excess.  The adhesive doesn't stick to the backing paper on the existing area, so this worked well.


Both sides done!

8) I peeled the backing off of the left side


9) I decided to place the foam board on the left side before peeling the backing off of the right side.  While I did this my husband held the foam board on the right side in place so that I could get it lined up well.  I put the center part of the foam board down first.  After placing it down I pressed it down by hand.


The foam boards meet in the blank area in the middle.


This is what it looks like as you're peeling the back paper off.  The adhesive transfers from the backing to the puzzle from the pressure put on it by the squeegee.

10) I placed the foam board on the right side and pressed down by hand.


11) Preparing to apply pressure to the front with the supplied squeegee.


All done!

12) This is where I tested the ultimate goal - separating the halves.  This is also where I realized an oversight.  OOPS!  A knob from the right can go up, but a knob from the left can't go down, because the foam board from the right half is below it.  Well then.  I also tried carefully bending the halves upward towards each other, but no luck there.


I'm open to any ideas, but I think what I need to do is carefully cut away a sliver of the foam board from each half along the middle so that it's no longer in the way.

Update: I was able to resolve the issue - read more here.
