Hi Glennbob and others
Epoxies do tend to crystallize out if they are cold for a long time.
The solution to that problem is put the can in some hot water for
several hours. BE CAREFUL THAT THE CAN DOES NOT TURN OVER;
YOU DON'T WANT WATER IN THE EPOXY. The crystals dissolve and
it is still good to use.
I never had that problem with West System because I use it up too
fast. My Aeropoxy sits around more.
You can avoid that by keeping it warm enough for you to be comfortable;
in the pantry (your wife will love that), in the closet, under the bed, etc.
Nothing happens to the hardener, I think, at reasonable hot or cold temps.
Big batches: I never mixed very big batches because I did not have
anyone to help me; you have to stir vigorously and try to spread it at
the same time. Big batches work if you have someone to stir to get
the heat out while you spread. The warmer the weather, the bigger
the problem.
Of course I am speaking of the West System. Aeropoxy is never a
exotherm problem because it reacts much slower at any temp.
Good luck.
