I recently shot a demonstration video to show the proper application of contact cement. During the first take I was somewhat distracted by the filming and I only applied cursory pressure with a J-roller. At the "moment of truth" when I tried to lift the laminate it separated easily from the substrate. Somewhat taken aback, I re-shot the video and concentrated on doing everything properly. I paid close attention to applying plenty of pressure with the J-roller. As expected, the laminate was impossible to remove in one piece. The moral of this story is to be sure to apply plenty of pressure when using contact cement. It may save you from a re-work!
