Adhesive for Foam Board Insulation

What is the best adhesive for bonding foam board insulation to a basement concrete block wall? The wall is coated with Thoroseal. Thanks!

I like PL Premium but you need good ventilation. PL300 foam board adhesive is supposed to be good as well, but I've not used it.

PL300 is fine. The adhesive should specifically say its for foam or else the solvents may dissolve the foam.

re: foam board

You want to use PL300, foam board adhesive. The adhesive doesn't always stick to the foundation wall so to help that make sure you lean a piece of heavy material against it for atleast 15 min to help facilitate the bond. Not all foundation walls are perfectly flat so the foam board may pop out in certain spots. Placing the heavy material will hold it down.
