Hi,
I'm in the process of painting my sisters new house. The ceilings are primed and finished, and the walls are all primed. I would like to tape the ceiling to give a crisper line to the wall finish, especially since she is leaning towards darker colors on the walls.
Is a week enough time to insure no paint peeling when pulling off the tape? Is there a minimum time period ?
Also, is there a particular or better blue tape to use ?

Thanks
