I have an air bubble on my grip mat, what should I do?

When exposed to heat and sunlight, tiny air bubbles located between the EVA grip mat and the board’s PVC might expand due to heat. If such a bubble appears in the EVA grip mat, you simply have to puncture
a small hole in the EVA grip mat, using a sharp object such as a sewing needle.​

Make sure you puncture the bubble by inserting the sharp tool perpendicular to the board, this will mitigate the risk of damaging the PVC material. Do not apply too much pressure and do this operation carefully so as to not puncture the PVC of the board. The EVA grip mat is soft and should not be hard to puncture, unlike the PVC, so you really don't need much pressure. ​
