Yes, that cementex needs to dry and you need to keep it open and well ventilated to exhaust the smell and the chemical essence of Cementex. I adopted the following schedule
Day 1 - Completed the outer panel of the door by applying Jumboloon with cementex. In the day time kept the windows down and door panels off. While at night kept the door panels off and Windows a little but rolled down (have airpress so you really cant tell if they are open much(.
Day 2 - left the doors untouched and completed the boot and removed its plastic shield
Day 3 - Completed the inner frame with Peel and Seal and attached back the plastic shield of both doors and boot. Also had fixed the mid-bass by then.
All worked and still works like a charm
