Great Stuff - Black VS Red

[Jason]

Sooo, i went to home depot to pick up some GS and found 2 different cans, one was black and one was red. whats the diff in useage for BGs or does it matter?

There is also a blue can. It is the amount of expansion as it cures.

red- minimal expanding, what i use. cures rigid
Black- Maximum expanding, expands well over 2". cures rigid
blue- minimal expanding with less pressure, cures flexible.

There is also a pro series that loads into a gun.

Coolio, thanks. i picked up 3 cans of the red myself. did 36X24, lol, first time i forgot to lay down the eggcrate i put it on, i woke up in the morning to the background half covered and the rest folded over on the floor ;(. its not as sticky as the can mentioned when fresh outta the can

LOL.. it's sticky, but it's heavy too, so gravity hits it pretty hard. if you drip some in a bad spot on the glass, don't smear it, let it dry and it comes right off. after 5 minutes it's nasty sticky.
