Mounting tape donut question

One side is red with a 3M logo, the other is plain white. Does it matter which side goes to the metal mounting disk and which goes to the mounting surface?

Since we mounted ours to an interior wall we did not use the supplied tape. I heard it was very hard to remove. We used the Velcro command strips and have not had an issue at all.

No, it doesn’t matter.

I have the white side to the disk, but can’t get the red 3M covering to come off. Now what?
