I have wondered that, When I started this I took some large pieces of cured foam and put them in a bucket with a weight on top for a couple weeks and it never seemed to absorb any water. I left a huge blob outside, and while it is not UV resistant (o it looses its shiny coating and becomes porous looking) I have never seen it absorb any water. I know some foams can absorb water.
Does anyone else have insight on the "Great Stuff" expanding foam absorbing water?
