This backer rod is closed cell and you will be able to use it outside
This will work perfectly for that application.
Thank you for the question. Backer Rod is intended to be used as a backing for caulking projects. The caulking should provide this barrier.
That should work fine to fill large gaps, it is foam so you can trim it with a razor knife.
It is a closed cell foam. Solvents in the paint would probably destroy it.
1" IS THE LARGES WE HAVE.

Yes. It is a type of styrofoam material that is meant to be covered-up with a caulking product. Thank you for your interest in our product. M-D Building Products
