Does anyone know how to make it sticky again

Not sure how to make it sticky again but with a couple small ones I had which would not stick well, I used duct tape and attached it to the tank, flattening it as best I could.

I used the cardboard packaging they came in put it over the pad and then duct tape the the edge of the cardboard to the glass. It helps to insulate and direct heat a little better.

I also have used duct tape over the back to make stick again, and if you can get insulting foam sheet that really helped my tank keep the temp up, easy to cut.
