I have a large LEGO project for school that I am hoping someone can
help with. The project involves building a large LEGO sculpture
requiring assembly with "glue" as it has to be on semi-permanent public
display and will be manhandled by kids. After 6 months of display, we
would like to recover the 50,000 LEGO pieces, so I am seeking a glue
that has the following requirements:
- Glue, adhesive, sealant or finish that holds bricks together
- does not eat ABS plastic (aka LEGO)
- clear and transparent so it does not effect aesthetics, should
dry to the same gloss of the original bricks
- water soluble (pieces can be soaked in hot water, possibly
requiring an agent also that is safe and environ friendly but ideally
just water) that completely recovers the bricks and does effect the
- a non-instant 'open' dry time (say, 12-24 hours) to allow for
correction of mistakes
- Sprayable since idealy it would hold on the outside so I don't
have to reassemble glued -or- easy to apply (a glue stick or
multiple-use tube or dispenser) and work with (does not bond to
fingers, easy clean-up).
- relatively inexpensive (not Elmer's but not industrially
- few fumes during use and none after drying
Does such a glue exist?
I have experimented with several glues and am currently using
watered-down Elmer's Washable glue sprayed in a light coating. It has
many of the above characteristics but the finish is slightly dull and
it's so watery that I cannot spray to an even coat (it drips and then
pools at the edges giving a uneven, bumpy look).
Thank you for your help!
