I have a fair amount of leftover roofing cement, which I would likely be able to use in the next year or two. Times past, leftovers always dry out too much to use. Once, _long_ ago, we put water on top ... which rusted the can. Oops.
Does anyone know of a way to preserve this stuff?
Thanks, G
The storage enemy is air.
To maximize storage life, transfer the remainder of the cement to smaller airtight containers that you can fill within 1/4" of the top. Seal with an airtight lid.
Give it a shot of an inert gas, then seal it.
viz. bloxygen.
My guess, the solvents are evaporating. Either through the can, or the can seal.
Right! Fart in the can, and get roof cement all over your ass.
Naah, you wait for late night TV, and buy "Fart in a Can". And we'll throw in a whoopie cushion, too! But, wait.....
Fart in a can, does that make you a buttstucker?
I've been working on the same can of Henry I've had for over 10 years now and it's still just fine (sometimes I have to give it a stir, though).

I've had gallon cans half empty sitting in my garage for several years and it was still fine when I next went to use it. Maybe you aren't putting the cap back on tight?
Generally for stuff that dries out I use saran wrapped layed on top of the material as well as the move to a container that it fills completely. Both seem to help but everything seems to eventually dry out given enough time. The one I really can't even slow down is opened pure silicon caulk. Even with the tip well sealed it still slowly hardens from the tip in.
