How to make Cricut Cutting mats sticky again - by Sami. Cover the edges of the mat, then spray it (outdoors) with Krylon Easy-Tack. Spray lightly. Let it dry. The adhesive actually needs to dry before it becomes sticky. Dry to touch in 3 hours so says krylon.com. Krylon Easy-Tack is acid free, low odor.
Do you feel like your cricut mats loose their "stick" rather quickly? Here is a quick and inexpensive way to "re-stick" them! You will need a repositionable spray adhesive, I used Krylon. DO NOT use permanent! Tape, my favorite is FROG tape, and a scraper.
