I just installed some self-stick vinyl cove baseboard and it's not wanting to stay stuck ... what can I do to fix this?

What kind of surface did you apply it to? Did you prepare the surface as the manufacturer directed?

I'm replacing old cove baseboard on drywall. I might have applied it too quickly ... not giving it enough time to warm up to room temperature. But now that it has reached room temp, could I use adhesive to reapply it to the wall?
