In the basement, gluing FOIL FACED Poly Iso to the foundation walls (Poured concrete). I was planning for XPS and was going to use proper foamboard adhesive.

However, I am now going to be installing Foil Faced Poly-Iso and really the adhesive I use has no contact with foam, but instead is in contact with the white foil backer of the foamboard and then concrete itself. Should I just use regular construction adhesive that is rated for sticking to concrete or...?
