Velcro adhesive is failing

I'm having a Velcro problem.
The problem I am having is the Velcro was replaced in our TM with industrial Velcro before we bought it. It looks as if the job was very well done, all the old adhesive removed, top notch all the way.
The Velcro sticks to its counter part very well, however the adhesive holding the Velcro to the wall is not holding very well at all. I'm thinking some 1/2" flat head sheet metal screws, or a heavy duty adhesive, or maybe both would solve this. Any Ideas, comments, or experience will be much appreciated.

P.S. I've looked (but might have overlooked) thru advance search, keyword Velcro, found many post, but not this issue yet, still looking.
