Hiya, I haven't' read back through all of the posts (it's a long thread!) so excuse me if I'm repeating anyone but when removing gelicure I file the free edge slightly to removed the 'cap' before wrapping (i use the Nubar artificial nail remover) I then place the clients hands in a heated wheat & lavender bag (the ones you get to help with achey muscles etc). The size and shape is perfect as you can lay their hands on it and then fold the ends over their hands - This has really helps to speed up my removal time and I think the combo of filing off the gel 'cap' at the free edge and the heated bag for me, has meant a lot less scraping at the free edge.
To save time further, I also work in this order: file edge, buff surface, wrap nail - one by one on first hand then into the heated wheat & lavender bag, repeat on second hand and by the time you've finished the second hand the first hand is ready to be removed, by the time you've removed the gelicure from the first hand/ shaped nail etc, the gelicure on the second hand is ready to be removed. This way there is no waiting around
I find all gel and gel polish product tends to be more stubborn to remove from the free edge whether their is a primer applied or not, I believe this is because the free edge is the driest part of the nail.
