Thank you for writing. As soon as you are complete on the puzzle we would love to get your details and photo for our Hall of Fame.

As far as to specifics of actual brands of glue, I’m sorry but I do not have that information. We have not assembled the puzzle ourselves
( too busy at the moment creating new art for new puzzles and other products ) and so I cannot give a first-hand experience. I can only relay what others have told us, and for
that we have put write-up’s in our tips and FAQ.

Educa the manufacturer of the puzzle does not recommend putting anything onto the surface of the puzzle. However I do know that some have written and said that they used special puzzle fixative on the front – however because of the size of this puzzle that could be costly. Certainly anything that you try should be tested on a smaller ‘old’ or cheap puzzle, and then cautiously used in a corner of the Life puzzle and if it passes these tests then go ahead.

I know that a local puzzle shop owner used the white wood glue (like Elmer’s) to glue an 18,000 piece puzzle, with satisfactory results except he did not know to glue it as a whole and glued it in the four sections as he completed them…unfortunately they didn’t join up!! You MUST use a glue that takes a while to dry so that you have time to position the sections together. However you do not want to use a glue ( i.e. like wallpaper glue) that is too wet that would make the cardboard of the puzzle swell.

I hope that this helps.

Keep in touch. And congratulations on getting this far!
