So I'm from Michigan and it is reallllllllly humid right now. I think the humidity is making the 3M 77 spray adhesive difficult to adhere to the curved parts of the ceiling (where it defies gravity). This step has been the most challenging and expensive part of the
renovation thus far. If you're a novice like me, expect to have to do things twice because there is room for error/learning especially considering the weather while you work. This can make you tired, sweaty, and high on fumes (be sure to wear a mask and have a fan blowing while you work). Good luck to everyone and your projects ♡
