The time will come when your mat completely loses all of its stickiness. We have a number of methods that will extend the life of your mat but we have found that one of the best products for making your mat sticky again is by using the Zig 2 Way Glue pen.
We have a mat that is one of our originals, so it is over 3 years old now and we are still able to use it because of this glue. We love it.
Check the video below to see how to re-sticky your mat using the Zig 2 Way Glue.
