Rubberized spray to seal rigid foam seams?
I've installed rigid foam on the top four feet of the interior walls of my basement. I plan to tape the vertical seams (and use cans of spray foam in some other places), but on the top and bottoms where the rigid foam meets the concrete, I'm looking for an easier way to seal it. Particularly where the panels meet the sill plate, caulking and cans of spray foam both seem like less than ideal options. I was thinking about buying some rubberized undercoating spray (ala Flex Seal) to seal some of the more difficult seams where the panels meet the concrete. Any thoughts? Will rubberized spray (or a version I could brush on) provide a legitimate moisture barrier to prevent mold? Is there any reason not to do this?
