Many of that type of adhesive is activated by pressure. So make sure to press really hard. Also many dont like being applied to cold surface temps. If applying in the winter it helps to clean the surface with alcohol and then warm it up with a blow dryer or heat gun.

YES! I used them to hang some large pictures (canvas wraps) in my office at work. The directions say to apply pressure for 1 minute, and preclean the surface with rubbing alcohol. Warming it makes sense, too.
