I used only Liquid Nails and a smile.....
to hold 2 x 4 foot sheet styrofoam panels of
insulation to my raw concrete basement walls.
None of it rests on the floor for support.

No idea how long it will stay glued.......
it's only been up 20 years to date without
a single panel coming loose.


That doesn't really surprise me. The solvent in
the liquid nails probably melted the styrofoam a
bit creating a good bond. Those panels are not
subjected to any significant stresses, certainly
no aerodynamic stresses nor do I imagine, does
your basement get as warm as an aircraft on a
hot day in teh sun. Probably not much exposure
to moisture or cold temperatures either.

Besides, those panels didn't weigh dick in the
first place.

For spars *I* would only use epoxy or a urethane glue
like Gorilla glue. Resourcinol glue, used in boat
building might be good too.

I suggest that you only rely on something that
a siginifacnt number of other folks have used
and survived. Learn from other people's mistakes.
