We usually specify hot mopping of Iso board or polyurethane adhesive (Olybond 500) for adhering tapered insulation to a concrete deck as part of a modified bitumen roof system. We have heard of the use of a spray mastic in lieu of the polyurethane - any one have any experience with the mastic and know who manufactures it?

Dow makes a product called Insta-Stik which is a low rise foam that bonds insulation to a variety of commercial roof decks. I would suggest contacting your local Dow building products specialits. The product can perform quite well if applied in the proper conditions and has excellent wind uplift approvals.
