So I'll be finishing my basement soon and will be using 1.5" pinkboard attached to my interior foundation walls.
What is the best method to fasten this to the wall (construction adhesive, caulk)?
Should the pink board touch the floor? if not how much room should I give myself?
Should it touch the joists?
What should I use to seal the between the boards (caulk, foam, teflon tape)?
Thanks,
Joe

For attachment, a few options:
It won't hurt anything.
Again, it won't hurt anything.
I've used house wrap tape in the past. Works fine. Another option, price allowing, is to use two thinner layers of foam instead of one thick one and overlap the seams.
You could also leave small gaps between all boards and then come back and fill with expandable foam. That'd give you the most air-tight and insulated envelope.
