What type of spray foam and adhesive is best to use with XPS insulation?
I'm going to put XPS insulation in the stud bays up against the concrete block wall of my basement. We had water problems on that wall, but I think I've corrected them from the outside. But there's the possibility that the concrete block could get moist in the future.
Considering that, what is the best adhesive to use for the foam board, up against the concrete. Are some more water resistant than others?
And what type of spray foam do you recommend for filling the gaps/edges around the XPS foam boards? Should I use minimal expanding spray foam or the stuff that expands more?
