Because the mat is flexible, glue alone will not hold it on for long. I've done a few and found, through trial and error, that my best success comes when I use a glue that remains flexible, and also using some type of mechanical fastener like the expansion type 2-piece rivets.
It takes some thought to get it affixed so that it will stay....my first few handles of it came off within a week of use....just took me a bit to understand the dynamics.
